Mova zapitіv SQL. Selection of data from the Access database for additional SQL requests Creation of collapsible SQL requests ms access

Golovna / Korisne PZ

The skin of the web retailer is the responsibility of the nobility of SQL, to write a query to the databases. If you don't want to mess with phpMyAdmin, it's often necessary to get your hands dirty to write low-level SQL.

For this reason, we prepared a short excursion into the basics of SQL. Let's get started!

1. Table creation

The CREATE TABLE statement is recognized for creating tables. As an argument, the names of the stovptsіv, as well as their types, are given.

Let's create a simple table on im'ya month. Won is composed of 3 columns:

id– Month number of the calendar rotation (tsile number).
name– The name of the month (a row of maximum 10 characters).
days– Number of days of the month (whole number).

Axis as a visualized SQL query:

CREATE TABLE months (id int, name varchar(10), days int);

Also, when folding the tables, add the primary key of one of the columns. Tse allow trimati records unique and speed up the drink on the vibirka. Let our mind have a unique name for the month (stovpets name)

CREATE TABLE months (id int, name varchar(10), days int, PRIMARY KEY (name));

date that hour

data type	Description
DATE	Date value
DATETIME	Date value and hour to minty
TIME	Hour value

2. Insert rows

Now let's populate our table months basic information. Adding records to the table is done through the INSERT statement. There are two ways to write down the instructions.

The first way is not to indicate the names of the columns where the data will be inserted, but to indicate an extra value.

This way of recording is simple, but not safe, there are no guarantees that in the world of expanding the project, that editing tables, columns will be sorted in the same order as before. A safe (and at the same time more cumbersome) way to write the INSERT instruction will change the value as well as the order of the statements:

Here is the first value on the list VALUES give the first appointed name to the first one.

3. Examination of data from the table

The SELECT statement is our best friend when we want to take data from a data base. It will win over more often, so put yourself up to the first division with respect.

The simplest choice is the SELECT instruction - a query that rotates all the columns and rows from the table (for example, tables on the name) characters):

SELECT * FROM "characters"

The zirochka symbol (*) means that we want to take data from all the posts. Since the SQL data bases are composed of more than one table, then it is necessary to specify the keyword FROM in the language, after which you can use the name of the table after a space.

In some cases, we want to take the data out of the table from the necessary statements. For whom, the deputy of the stars (*) is guilty of me through whom to write down the names of the bazhan saints.

SELECT id, name FROM month

In addition, we want the results to be sorted out in order. SQL has the benefit of the ORDER BY help. You can accept an optional modifier - ASC (for locking), which sort for growth or DESC, which sort for falling:

SELECT id, name FROM month ORDER BY name DESC

At the same time, change the ORDER BY to leave it in the SELECT statement. Otherwise, you will see a reminder about the pardon.

4. Data filtering

Have you figured out how to choose from the data base for additional SQL data strictly the same rows, but how do we need to take the next row? To help here come the brains WHERE, which allows us to filter the data in the fallow of the mind.

We choose only those months from the tables month, which have more than 30 days for the additional operator more (>).

SELECT id, name FROM month WHERE days > 30

5. Expanded data filtering. Operators AND and OR

Previously, we victorious filtered data from victories of one criterion. For more collaborative filtering of data, you can win the operators AND and OR and the operators (=,<,>,<=,>=,<>).

Here we may have a table, how to avenge the most sold albums in the current hours. Let's take a look at those that are classified as rock and that may have sold less than 50 million copies. You can easily use the path to place the AND operator between two minds.

SELECT * FROM albums WHERE genre = "rock" AND sales_in_millions<= 50 ORDER BY released

6. In/Between/Like

WHERE also supports a few special commands, allowing you to quickly change the most common victories. Stink Axis:

IN - to serve for the appointment of a range of minds
BETWEEN - check what is the value of the specified range
LIKE - whispering for song patterns

For example, yaksho mi wanto vibrati albums z pіpі soul with music we can win IN("value1","value2") .

SELECT * FROM albums WHERE genre IN ("pop", "soul");

If we want to take away all the albums seen between 1975 and 1985, we are guilty of recording:

SELECT * FROM albums WHERE released BETWEEN 1975 AND 1985;

7. Functions

SQL stuffed with functions, like shattering different cursive speeches. Axis of action with the most frequent victories:

COUNT() - rotate the number of rows
SUM() - rotate the total sum of the numerical value
AVG() - rotate the mean value from the blank value
MIN() / MAX() - take the minimum / maximum value of the station

To remove the rest of our tables, we are responsible for writing the following SQL query:

SELECT MAX(released) FROM albums;

8. Drink

At the front point, we learned how to work simple roses from denim. If we want to win the results of these investigations, we cannot do without investments. Let's say we want to see artist, albumі release year for the oldest album at the table.

We know how to take into account specific items:

SELECT artist, album, released FROM albums;

We also know how to take the early river:

SELECT MIN(released) FROM album;

All that is needed at once - just combine two drinks for help WHERE:

SELECT artist, album, released FROM albums WHERE released = (SELECT MIN (released) FROM albums);

9. Joint tables

In folding data bases, there are a few tables, tied to one another. For example, below are two tables about video games ( video_games) and rozrobnikiv videogor ( game_developers).

In tables video_gamesє retail column ( developer_id), but he has a whole number, but not the name of the retailer. Tse number є іidentifier ( id) of the relevant retailer from the retailer tables of Igor ( game_developers), linking two lists logically, which allows us to win the information that is collected in them both at the same time.

If we want to create a file, which turns everything we need to know about games, we can use INNER JOIN to link the columns of both tables.

SELECT video_games.name, video_games.genre, game_developers.name, game_developers.country FROM video_games INNER JOIN game_developers ON video_games.developer_id = game_developers.id;

The simplest and most extensive JOIN type. A sprinkling of other options, but the stench zastosovuetsya to lesser parts of the vipadkiv.

10. Aliasey

If you marvel at the front butt, then you remember that there are two columns of the title name. You beat the pantel, so let's put in the pseudonym of one of the repetitions, for example, name from tables game_developers will be called developer.

We can also quickly ask for table aliases: video_games called games, game_developers - devs:

SELECT games.name, games.genre, devs.name AS developer, devs.country FROM video_games AS games INNER JOIN game_developers AS devs ON games.developer_id = devs.id;

11. Data update

Often we can change the data in some rows. SQL is asking for help with the UPDATE statement. The UPDATE instruction is composed of:

Tables, where the meaning for the replacement is known;
Names of stovptsіv and їх new meanings;
Selected for help WHERE rows, if we want to upgrade. As much as possible, then all the rows in the tables are changed.

Below is a table tv_series with serials with your own rating. However, a small pardon crept into the table: I want a series Gras of Thrones and is described as a comedy, but not really. Let's fix it!

Table data tv_series UPDATE tv_series SET genre="drama" WHERE id=2;

12. Vision of data

Seeing a row of tables behind the help of SQL is a very simple process. All that you need is to choose a table and a row, which you need to see. Let's see from the front butt the remaining row at the table tv_series. Rush for help instructions >DELETE

DELETE FROM tv_series WHERE id=4

Be careful when writing DELETE instructions and change your mind about WHERE, otherwise all rows of tables will be deleted!

13. Table view

If we want to see all the rows, or delete the table itself, then use the TRUNCATE command:

TRUNCATE TABLE table_name;

In case we really want to see both the data and the table itself, we need the DROP command:

DROP TABLE table_name;

Be careful with these commands. Їx you can’t say!

On which we will complete our assistant from SQL! We didn’t reveal a lot of things, but those that you already know can be enough to give you a little practical experience in your web-carrier.

Similar to Microsoft Access SQL and ANSI SQL z. Microsoft Access SQL is highly compliant with ANSI-89 (rіven 1) z. Deyakі ANSI SQL codes are not checked in Microsoft Access SQL z. Microsoft Access SQL reserved words that are not supported by ANSI SQL

Syntax extensions. Access 2000 (MS Jet 4.0) has an extension that brings language closer to the ANSI SQL-92 standard - a mode that is more accessible than the MS OLE DB Provider for Jet

Other rules are wicked for the Between construction. . . And, for example, the offensive syntax is: double 1 Between value 1 And value 2 In Microsoft Access SQL, value 1 can be greater, lower value 2; move ANSI SQL value 1 may be less than value 2 or more.

wildcards z At the move Microsoft Access SQL the hour of the operator's variable Like is trimmed as the wildcards of the ANSI SQL move, so the wildcards signs abo vіdpovіdat sing zrazku.), scho susuyutsya Microsoft Access. It is not possible to use ANSI wildcards and Microsoft Access overnight. It is allowed to use only one set of characters, they cannot be changed.

ANSI SQL possibilities that are not shown in Microsoft Access SQL z. Iznstrukiye TRANSFORM Feeling the piditrim of the Subsyvo recording Z (Subsyniya recording, in the yard of the pydrahovu, the number is the number of the Vikonchi Statistical Rosrakhunki, Pisly the results of the Vigilov Tables, one rows.).

ANSI SQL possibilities that are not shown in Microsoft Access SQL z. Alternative propositions LIMIT TO nn ROWS for the exchange of a number of rows, as they are rotated by the power supply. z. Additional statistical functions of SQL, such as St. Dev and Var. P

ANSI SQL possibilities that are not shown in Microsoft Access SQL z. For assigning parameters to the input (Input from parameters. Input, in either one or the same time, the value that you assign to the selection, is entered in the interactive mode in short order. Input from the parameters is not the only type of input; it is functionally expanding input to the PARAMETERS. option.)

Command syntax SELECT [predicate] (* | table. * | [table. ]field_1 [, [table. ]field_2 [, . . . ]]) FROM viraz [, . . . ]

Arguments of the SELECT statement Predicate One of the next selection predicates: ALL, DISTINCTROW or TOP. The predicates are victorious for the exchange of the number of records that are rotated. Even though it is impossible, the predicate ALL is used for the lock.

Predicates ALL, DISTINCTROW, TOP z. SELECT ]] FROM table z. ALL - All records are selected to match the mind, set in the SQL statement.

The DISTINCT predicate - includes records to remove the values that are repeated in the selected fields. The resulting set of data neonizations

DISTINCTROW predicate - Omit data based on exactly repeated records, not just fields that are repeated. The DISTINCTROW predicate is ignored, as it only requires one table to be deleted, or the fields of all tables.

DISTINCTROW z. SELECT DISTINCTROW spіvrobіtnik. fio, layout. item_code z. FROM Spіvrobіtnik INNER JOIN layout z. ON Spіvrobіtnik. practice_code = layout. practitioner_code;

DISTINCT SELECT DISTINCT SPIVROBITNIK. PIB, layout. item_code FROM SPIVROBITNIK INNER JOIN layout ON SPIVROBITNIK. Practice_code = distribution. practitioner_code;

In order to be included in the DISTINCT query, it is required to select the value “so” for the power of the query “unique value”, and to be included in the query DISTINCTROW it is required to select the value “so” for the power of the query “unique records”.

Predicate like TOP. TOP n - Rotate the number of records that are on the cob or in the last range, described by the additional proposition ORDER BY.

butt. Pick up the 5 largest departments SELECT TOP 5 department. [Department_name_outside], Count(resource_resources. Requirement_code) AS [Number of requisitioners] FROM department INNER JOIN requisitioners ON department. Code_department = spіvrobіtniki. Department_code GROUP BY department. [External_department_name] ORDER BY Count(resource_resource_code) DESC;

Arguments of the SELECT statement field_1, field_2 are the names of the fields, for which you need to select data. As soon as you increase the sprat of watering, the stench will be taken in the appointed order.

Arguments of the SELECT statement Alias_1, Alias_2 are the names that will become the headings of the columns instead of the original names of the columns in the table.

Apply an alias name for the name of the enumerated field. Example 1 SELECT speller. PIB, [salary]*0. 5 AS Prize FROM Spivrobitnik; Butt 2 SELECT Avg (salary) AS Average_salary FROM salary;

Arguments of the supporter of the koristuvach SELECT Zovnishnya. Base. The name of the data base is given, so as to avenge the tables, assigned for the additional argument of viraz, because the stench is not found in the current data base.

Proposition FROM SELECT list. Watering FROM viraz z Viraz - viraz, which designates one or more tables, stars are drawn. This script can be named after the table, saved data, or as the result of the operation INNER JOIN, LEFT JOIN, or RIGHT JOIN.

Spіlna obrobka kіlkoh (3) table SELECT spіvrobіtnik. PIB, subject. [item name in short] FROM list INNER JOIN (item INNER JOIN [volume with items] ON item. [item code] = [volume with items]. [discipline code]) ON list. Code = [volodine items]. [spіvrobіtnik code];

Between construction. . . And viraz 1 BETWEEN viraz 2 AND viraz 3 z. Microsoft Access SQL may have higher 2, lower 3, but ANSI SQL may not.

The Like predicate Symbols for the template Variable symbols for the template are matched with the Like predicate. Character template ANSI SQL MS Access SQL z Which character? _ (subscript) z Be a group of any characters * % z Be a single character that must appear before character_list [char_list] daily z Any single character that must not appear before character_list [!char_list] daily

z. Two remaining capacities - only for Access 2000 z. Access 2000 like ANSI SQL-92 can use ANSI z wildcards. It is impossible to mix signs in one drink

Proposition GROUP BY z. SELECT list. The FROM field is the WHERE table of the mind. Vіdboru z are grouped. Fields – field names (up to 10), which are selected for grouping records. The order of field names in arguments is grouped. Fields determine the level of grouping of skin s cich watering.

GROUP BY z Vary the WHERE clause to exclude records from the grouping, and the HAVING clause to stop the filter before the records after the grouping. z When the GROUP BY proposition is chosen, all fields in the field list of the SELECT statement must be included in the GROUP BY proposition, otherwise they are chosen as arguments of the SQL statistical function.

butt. Chairs, where there are more than 5 practitioners. SELECT spіvrobіtnik. [Department code], Count(requirer PIB) AS [Number_of_staff] FROM reference GROUP BY reference. [Department code] HAVING (((Count(spіvrobіtnik. ПІБ))>5));

Head of the table “firms”, “spivrobitniki” and “attestation”. It is necessary to determine the number of attested specialists for skin firms (one specialist can be certified for a PP kilkom).

SELECT statement. . . INTO Syntax z. Creates a request to create tables. SELECT field_1[, field_2[, . . . ]] INTO is new. FROM table dzherelo

Request for a joint (appendix 1) SELECT Name, Location FROM Postal workers UNION SELECT Name, Location FROM Clients ORDER BY Location;

Request for a union (Example 2) SELECT Name, Location FROM Postal workers UNION ALL SELECT Name, Location FROM Clients; - UNION ALL ensures the rotation of all records, including repetitions

The creation of a subordering query with a selection of the query retailer QBE As a subordering query to select the minds of the field, enter the SELECT statement in the row row of the Umova selection in the column of the field. The SELECT statement must be placed at the round head.

Instruction DELETE z Delete records delete records more than once, but not more than the specified fields. To view the data of a specific field, create a request for updating records, which replaces the actual values. On the view of the DROP command, the table structure and all powers are saved

Access DBMS has two types of requests: QBE - request for an instant i SQL(Structured Query Language) - language of structured queries. The request is formed on the basis of a way to fill in a special form for the request at the "Constructor of Requests" window. SQL - requests are created by programmers from the SQL sequence - instructions. SQL is formed, as a rule, by programmers on the request form, which is entered by the command "Designer of requests" on the "Creation" tab, and then "SQL Mode" is selected from the View menu. Mova SQL assignments to work with data, tobto. for creation, modification and data management in relational databases.

Specify that the number of SQL request modes (for ANSI-89 SQL and ANSI-92 SQL modes) conforms to ANSI-89 SQL and ANSI-92 SQL standards.

Instructions to write a description of a set of data in mov SQL. SQL statements are composed of propositions (SELECT, FROM, WHERE, etc.). Propositions in mov SQL, terms are combined (operators, commands, identifiers, constants, etc.). The instruction is initiated by the operator (one of the commands SELECT, CREATE, INSERT, UPDATE, DELETE, etc.) and ends with a blob. Basic SQL statements: SELECT, FROM and WHERE.

For example, the SQL statement:
SELECT Students.StudentID
FROM Students;
the propositions "SELECT Students.StudentCode" and the propositions "FROM Students".

SELECT proposition revenge operator SELECT and identifier"Students.StudentCode". Here, outside the name of the "Student Code" field, it will display the name of the "Students" table of the data base. SELECT - selects a field to retrieve the required data. The FROM clause is composed of the FROM operator and the identifier "Students". FROM - designates a table to sweep fields assigned to the SELECT keyword.

The next step is to specify that it is necessary to correct the syntax for shaping my SQL query. Irrespective of those that the syntax of the SQL movie is based on the syntax of the English movie, but for different DBMS the syntax of the SQL versions can be changed.

Іsnuє kіlka types of requests: for vibrating, updating, adding and revising records, cross-request, creating that remote table, adding tables again. Let's widen the most - ask for a vibrate. Ask for a selection to select the necessary cortical information to be included in the tables. The stench is created less for po'yazanih tables.

To have a look at SQL - ask for a selection in Access 2003 or 2007 DBMS;

Rice. one.

We take the SQL statement (SELECT) to select data from the Access 2003 database according to the student success criterion "Score = 5" (Fig. 2).

Rice. 2.

Like the SELECT statement (Fig. 1), it shows the data to be collected in the SQL language: SELECT - sets the names of the fields, which are changed by the names of the tables, in which the data is to be stored; FROM - assigns tables and relationships through the key fields of the table (for which the INNER JOIN...ON construction is selected), based on which data is selected; WHREME - determines the choice of watering; ORDER BY - sets the sorting method by age (sorting by age is selected by default) the value of the "Priority" field in the "Students" table.

As you see the instructions for selecting data from the database, SQL language determines what is necessary to take from the data base, the DBMS is entrusted to its user, the SQL language language does not have its own tools for managing the programs.

SQL request - this is a request that is created for additional SQL instructions. Mova SQL (Structured Query Language) is used when creating queries, as well as for upgrading and managing relational databases, such as Microsoft Access databases.

When you create a query in Design mode, Microsoft Access automatically creates an equivalent SQL statement. Є a number of zapitіv, yakі can be zrobiti less in SQL mode. It is often easier for advanced programmers to write once in SQL, then form a request.

Type of request in the constructor:

With folded roses, the result is brought to successively work a little water. It dawned on me that the duties of vikonuvatsya automatically without the participation of the koristuvach.

For which macros are victorious, which are composed of dekіlkoh commands, which are sequentially victorious.

Calculation of requests, the possibility of creating and editing formulas.

For fields from assignments in the scheme, the table can be specified whether it is calculated.

In order to increase the calculation, it is necessary to add additional calculation fields, the values of which are calculated on the basis of the values of other fields.

Sub-bag requests, grouping, sub-bag functions.

The sub-bag supply is created for the support of the Zvedeniya supply mode.

You can twist three tables, including a lucky table.

With this, you can either power up the shortcut menu (right mouse button) and select the “Group Operations” sign.

A new row of grouping will appear at the letterhead.

Sub-bag functions: for the field, if you want to protect the sub-bags, select the “Sum” function from the list to add all the values of the selected fields. The function "Pidrahunok" takes into account the number of field values. Info editing microsoft

Request - tse completion to the DBMS to the end of any operations from data: the selection of part of the data from the pledge, the addition of the calculation of the fields, the mass change of the data, and so on.

At the request you can:

- select information from a number of related tables;
- Vykoristovuvati skladnі umovi vіdbora;
- Koristuvach can enter the values of the parameters himself, add the fields that are calculated;
- Vikonati pіdbags rozrahunki.

Types of requests:

- vibrka;
- Creation of tables;
- updating (change of data);
- Adding records;
- Viewing records.

Ask for vikoristovuyutsya like dzherela records for forms and calls. Zdebіlshoy and in forms, and in zvіtakh before the seer, it is necessary to select a part of the data for whatever minds and sort the data. Tse rush for help drinking. Zapit can be saved okremo or bindings to the form or zvitu.

Microsoft Access has several types of requests.

Sometimes you may need to transfer the Microsoft Office Access (Access) file-server database to the client-server DBMS format. Ring out for whom ODBC is victorious. However, for porting to Microsoft SQL Server (MS SQL) Access DBMS and MS SQL may need to be manually specialized.

There are three ways to transfer databases from Access to MS SQL. Let's take a look at everything on the example of a simple database of data, which is composed of two tables and one charge.

Data base transferAccess ("Master of conversion to the formatSQLserver")

To perform the transfer, you need to click on the "SQL Server" button in the "Data Migration" area of the "Database Robot" tab.

It is necessary for you to choose where the data will be transferred.

Two options are possible:

Export from already existing MS SQL data base;
Creation of a new base of tribute (for lock-in).

Specify the name of the server to which the data base is transferred, the name of the data base and specify the password for the connection.

To select one table, use the ">" button, and to select all tables, use the ">>" button. In order to see the transferred recognition of the button "<» и «<<» соответственно.

After selecting the table, you can insert additional parameters of their transfer. Other versions of Access can export both the tables themselves and the data, and link to them. It means that the hour of the necessary migration of the data base will soon pass, the shards do not need to be recreated after the transfer.

Create a new client-server add-on with an Access interface;
Turn on the transfer of tables in the external database as if they were the same (for locking);
Do not beat the annual days with the weekend data base.

If all the necessary information is selected, you can turn up to one of the front edges for verification, or start the transfer process by pressing the "Finish" button.

The head of the transfer process is visualized in a special window.

Once the migration is complete, you can open SQL Server Management Studio and view the result.

This method is the most simple and convenient, but, unfortunately, it allows you to transfer only tables and accompanying elements (indexes, links, etc.).

Database importAccessMicrosoftSQLserver

MS SQL can import data from different servers. However, direct import from Access is only possible for databases in the old format (.mdb).

Detailed instructions for importing such databases can be found.

Import of databases of new formats (2007 and above) is richly folded.

There are two ways to accomplish this task:

First, export the Access database in the old format.
With such a mindset, one can easily speed up the instructions given for the help;
Wicker ODBC.
Created a database database for Access databases from upcoming connections through a new one from MS SQL Server.

Unfortunately, the way, due to ODBC hacks, is to fold in different 64-bit versions of Windows.

The reason is that 64-bit versions of MS SQL are bundled with 32-bit versions of SQL Server Management Studio. Tsya conditions lead to the fact that Access data bases, for some kind of data creation on the basis of 64-bit drivers, cannot be imported for additional software programs.

There are still two exits here (there are only ways to use the graphical interface for help):

tweak 32-bit versions of Windows, MS SQL, Office;
Vykoristuvate more than 32-bit Access and nalashtuvati dzherelo danih behind the help of a 32-bit ODBC manager (name the file C:\Windows\SysWOW64\odbcad32.exe);
Vykoristovuvaty alternative software for robotic MS SQL.

However, it is still worth trying to improve the process of import, coryst, which may appear richer less, lower strength and time.

When importing, the tables themselves and theirs together and more than nothing are transferred (come with the possibilities of the previous method).

Also, it should be noted that with direct import from Access, the problem of exporting requests is often violated (there is no access to requests via ODBC). Prote, ask for locks, they are imported to the MS SQL data base like standard tables.

Luckily, you can more fine-tune the settings of import parameters and you can manually override SQL request for table creation with application notification.

For what you need in the window on the screenshot for the selected Access request, press the "Change" button.

At the end, press the button “Change SQL…”

Vіdkriєtsya vіkno editing SQL request, in the future, in the state, it is necessary to replace the request, generating automatically

let's get our hands on it.

As a result, the request from Access will be transferred to the MS SQL database correctly, as a representation, not a table.

Obviously, it’s like nalashtuvannya tse kopitka is hand-made, which means you have the same knowledge and skills, but still, as it seems, “better, lower than nothing.”

Therefore, this method of transferring Access databases to MS SQL is more suitable for qualified practitioners of both DBMSs.

Below is an example of importing Access databases for the help of ODBC in a 32-bit version of Windows. For the 64-bit version of Windows, the same time the import works for the 32-bit version of Access, but sometimes it works in the 32-bit ODBC manager.

Let's create a hell of a lot of data.

Vіknі vkazuemo yoga im'ya.

Let's press the "Select" button and indicate to which Access database you need to connect.

If it is indicated that the data base file is to be stored, it is not necessary to press the "OK" button and the data base for the required Access database is ready.

Now you can proceed directly to the import of data bases from MS SQL.

For this, in the context menu of the data base, in which it is necessary to select the import, select the item “Download” -> “Import data”.

Approved by "Master of Import and Export of Data"

In the "Dzherelo data" list, as it turns out, it is necessary to select ".Net Framework Data Provider for Odbc" (as it is not selected for locking) and in the Dsn row in the table, indicate the name of the created data provider for the Access data base. The Connection String will be formed automatically.

It is necessary to indicate in the database which instance of MS SQL import is required. For this next pressing, the "Dal" button can be selected in the "Assigned" list or "Microsoft SQL Server Native Client" (as shown in the screenshot below) or "Microsoft OLE DB Provider for SQL Server", you may need a database named after that password for connection.

Then it is necessary to select tables, which will be imported. As it was set higher, the hour of the ODBC request import request Access is not available. Therefore, on the front screen in front of the list of objects for import, this list will have only tables.

For the help of the ensigns, you can choose like a mustache table in a row (which is broken in the same butt), so the deacons are okremo from them.

Then a window with residual parameters for the import process will be shown. Let's leave all the meaning behind the locks.

When you click on the Done button, the import process will be clicked. If everything is done correctly and the import is successful, the window with information about the import will not receive pardons (div. screenshot below).

To complete the robotic master, just press the "Close" button.

The result can be seen in SQL Server Management Studio.

Transferring the data base from the sideODBC

This method is universal for exporting data from Access to any other DBMS. More than enough to get the job done with ODBC.

An example of such an export is already seen in the article ""

ForMSSQL data base transfer methodAccess is not a problem, shards are exported less than tables with data, and zapity are exported less than standard tables.

However, such a possibility of transferring dosi є (version 2014 did not turn out to be a fault). To that we can look and її tezh.

For the cob, let's create data for robots with MS SQL (let's not forget the Koristuvalnitsky DSN).

Specify driver for gerel.

After that, the process of creation and creation will be launched.

Assignment im'ya dzherela danih that vkamo іm'ya instance of MS SQL, which is necessary for connection.

If the data base is specified, it is planned to transfer the chi request table. Rescheduled for helpODBC can only be used with an existing data base. To that, as it is necessary to transfer the data to the new data base, it is necessary to create it in advance.

After pressing the “Done” button, a window will be shown with sub-bag information about the data that is being created.

For the rest of the dzherelo danih bulo done, just press the "Ok" button. And better yet, in front of you, reverse your practice by clicking on the button "Reverse the data."

If everything is done correctly, you will be informed about the successful revision.

Now, if there is a need for them, it is possible to start the process of transference without any intermediary. As an example, it is exported from the data base of the single request “Contacts Request”.

For whom it is visible to the target, press the "Dodatkovo" button in the "Export" area of the "External data" tab. At the menu that has opened, select "ODBC Database".

Time has no other meaning.

After pressing the "OK" button, it is necessary to select the created data.

Let's enter your password to connect to the server.

After pressing the "OK" button, the export will be disabled.

Prote, as it was said above, the result of the export from time to time is not correct.

Instead of the "Contacts Request" representation, a one-menu table was created in the MS SQL database.

On the other hand, to export more than tables, after export it is necessary to add anonymous addendums (re-creation of links later.). For this reason, the descriptions of the method of transferring databases from Access to MS SQL are practically not zastosovuetsya.
