Structured Query Language (SQL) Non-procedural (declarative) language common to most relational database systems. – Used by the database system internally and by users to manipulate and query the data. – Uses set theory (as opposed to row processing) to process requests. – Limited but flexible set of commands. – Free-form, uses semi-colon as statement terminator in most databases. Name: The relationships for the Northwind Database are shown below. Paste the SQL statements for the queries below the query statements. OutOfStockProducts: Make a.

This topic shows you how you can use SQL Prompt. The following examples are provided:

You can follow the examples on your own system. Most examples in this topic use SQL Server 2005 and you will need access to a SQL Server on which the AdventureWorks example database has been installed. In addition, the cross-database queries and queries using linked SQL Servers examples use SQL Server 2000 on which the Northwind and pubs example databases have been installed.

Before you follow the examples, to ensure that you see the same results as those illustrated, set your options to the default values. To do this on the SQL Prompt menu, click Options, and then click Restore All Defaults.

Typing a simple query

This example shows you how you can use the SQL Prompt candidate list to assist you when you are typing a query.

1. On the Options dialog box, click the Inserted Candidates tab, click the Formatting page, and then select the Qualify object names check box and click OK.
2. In your query editor window, type:

   and press SPACEBAR.

   The candidate list displays the Suggested candidates category; tables are displayed at the top of the list.

3. Type c to filter the list by candidates that begin with c.

   The Contact table is highlighted.

4. Press ENTER to insert the Contact table.

   SQL Prompt inserts the table name. Because you selected the Qualify object names option, SQL Prompt qualifies the table name with the schema (owner) name Person. The identifiers are surrounded with brackets [ ]; this is another option in Inserted Candidates, Formatting, which you can switch off if required.

5. Type WHERE and press SPACEBAR.

   The candidate list displays column names for the Contact table and associated data types.

6. Type L and press ENTER to insert the LastName column.
7. Type LIKE 'Fr%' so that your query returns rows where LastName begins with Fr.

   By default, when you type an opening quotation mark, SQL Prompt automatically inserts the closing quotation mark. If you type the closing quotation mark (for example, because you have not noticed the automatic insertion), SQL Prompt overtypes the auto-inserted quotation mark. You can change this setting and other auto-completion options, on the Auto Insert, Closing Characters options page.

8. Delete the * (after SELECT) and press CTRL+SPACEBAR to display the candidate list.

   The candidate list displays columns from the Contact table.

   Note that you must always type * after the SELECT keyword, even when you want use SQL Prompt to insert the column list later. If you do not type * the candidate list may display incorrect candidates. For more information, see Troubleshooting

9. Type f and press ENTER to insert the FirstName column.
10. Press COMMA, type L, and then press ENTER to insert the LastName column.

Expanding column lists

These examples show you how SQL Prompt can expand a column list when you are using a SELECT statement.

In the first example, you type SELECT * and you specify the tables or views in the FROM clause; you can then complete the column list by placing the insertion point after the * and pressing TAB:

1. Ensure that Qualify object names is selected on the Inserted Candidates, Formatting options page.
2. In your query editor window, type:
3. Place the insertion point after the *
4. Press TAB.

   SQL Prompt expands the column list.

This next example shows how SQL Prompt can complete the column list for you when you type a SELECT table.* fragment and press TAB.

1. Type:

   SELECT [Person].[Contact].*

2. Press TAB.

   SQL Prompt expands the column list. This time, SQL Prompt qualifies the columns with the table name and schema (owner) name irrespective of your Qualify column names option setting, because you specified the table name.

Selecting columns

This example shows how you can use the SQL Prompt column picker to select columns for the column list in a SELECT statement:

1. Type:
2. Delete the * after SELECT and press CTRL+SPACEBAR to display the candidate list.

   The candidate list displays columns from the Address table and the AddressType table.

3. Press CTRL+LEFT ARROW or click to display the Column picker category.
4. Select the some columns.

   To select a column, click the check box, or highlight the column and press SPACEBAR. You can use SHIFT and CTRL to select multiple columns.

5. Press ENTER to insert the selected columns into your query editor.

For more information about how to use the column picker, see Using the Candidate List.

Generating full INSERT statements

These examples show how SQL Prompt generates full INSERT statements.

1. On the Options dialog, click the Inserted Candidates tab, click the SQL page, and ensure that the following check boxes are selected:
   • Insert full INSERT statement
   • Insert default values for data types
   • Show hints for data types
2. In your query editor window, type INSERT INTO cus
3. Select Customer.

   SQL Prompt inserts the INSERT statement. The insertion point is positioned for you to enter the values.

In the following example, hints are not shown.

1. On the Options dialog, click the Inserted Candidates tab, click the SQL page, and clear the Show hints for data types check box.
2. In your query editor window, type INSERT INTO cus, and select Customer from the candidate list.

   SQL Prompt inserts the INSERT statement. The insertion point is positioned for you to enter the values.

In the following example, default values are not shown for data types.

1. On the Options dialog, click the Inserted Candidates tab, click the SQL page, and clear the Insert default values for data types check box.
2. In your query editor window, type INSERT INTO cus and select Customer from the candidate list.

   SQL Prompt inserts the INSERT statement. The insertion point is positioned for you to enter the values.

Executing stored procedures

This example shows how SQL Prompt inserts the parameters for stored procedures when you type EXEC and you select a stored procedure.

1. On the Options dialog box, click the Inserted Candidates tab, click the SQL page, and then ensure the Insert parameters for functions and stored procedures and Show hints for data types check boxes are selected.
2. In your query editor, type EXEC and then press SPACEBAR.

   SQL Prompt displays a list of stored procedures at the top of the candidate list. The schema panel shows the creation SQL for the highlighted stored procedure. For example:

3. Select a stored procedure by pressing UP ARROW or DOWN ARROW to highlight it, and then press ENTER to insert it.

   SQL Prompt inserts the parameters for the stored procedure and inserts the associated data types as comments. For example:

Using snippets

SQL Prompt is pre-configured with default snippets. To see the snippets, press CTRL+SPACEBAR and then CTRL+LEFT ARROW to display the Snippets category.

This example shows you how to insert the snippet code for disabling all triggers on a table.

1. Type:

   atdta

   The candidate list displays a description of the snippet and the schema panel displays the snippet code.

2. Press ENTER to insert the snippet code.

   SQL Prompt places the insertion point after TABLE for you to type the table name.

Cross-database queries and queries using linked SQL Servers

These examples use SQL Server 2000 on which the Northwind and pubs example databases have been installed.

The first example begins using the pubs database, and then accesses a table in the Northwind database.

1. On the Options dialog box, click the Listed Candidates tab, and on the Cross-Database Support page ensure the Enable cross-database and linked server support check box is selected.
2. In your query editor window, type:

   The candidate list displays the candidates. For example:

3. Select Northwind.
4. Type . (dot).

   SQL Prompt caches the Northwind database, and displays a list of the owners in the database. (Note that you may be asked to enter authentication credentials if SQL Prompt has been unable to log on to the database.)

5. Select dbo, and type . (dot) again.

   SQL Prompt displays the candidate list containing tables and views.

6. Select the Products table, then place the insertion point after the *.
7. Press TAB.

   SQL Prompt inserts the columns from the dbo.Products table in the Northwind database.

This next example shows a distributed query using a linked SQL Server 2000 instance from a SQL Server 2005 instance. The linked SQL Server 2000 instance is configured with the name READONLY.TESTNET on the SQL Server 2005 instance. For more information about linking servers, refer to SQL Server Books Online.

1. On the SQL Server 2005 instance, in your query editor window, type:

   The candidate list displays the candidates. For example:

2. Select the linked SQL Server, and then type . (dot).

   If the SQL Server uses SQL Server authentication and you have not saved the connection details, SQL Prompt displays a dialog box for you to enter the authentication credentials.

   If you click Do Not Connect, in future SQL Prompt will not display the candidate list for that SQL Server automatically; if you want to enter the credentials at a later date so that you can see candidates, press CTRL+SPACEBAR.

   For this example, enter the credentials and click Authenticate, and then press CTRL+SPACEBAR to display the candidate list. The candidate list shows a list of databases on the linked server.

3. Select Northwind, and then type . (dot).

   You may need to press CTRL+SPACEBAR to display the candidate list. If the authentication credentials you entered allow you unrestricted access to the SQL Server, you are not prompted to enter them again.

4. Select dbo from the list of candidates, and then type . (dot).
5. Select the Customers table from the list of candidates, then place the insertion point after the *.
6. Press TAB.

   SQL Prompt inserts the columns from the dbo.Customers table in the Northwind database.

Common table expressions (CTEs)

This example shows you how you can use SQL Prompt when writing a query that contains a CTE (common table expression). A common table expression is a named results set that exists only for the duration of the query.

This example uses the Northwind database.

1. In your query editor window, type:

   This statement defines a CTE called DirReps that creates a simple set of results, the number of employees that report to each manager.

2. In your query editor window, type:

   and press SPACEBAR.

   The candidate list displays the Suggested candidates category. The common table expression you have defined is displayed at the top of the list.

3. Press ENTER to insert the DirReps common table expression.
4. Type

   The candidate list displays the ManagerID column, the only column defined in the common table expression that matches the first character typed.

5. Press ENTER to insert the column name.

Note that SQL Prompt also supports recursive CTEs, and multiple CTEs within a single WITH statement.
