Building Queries in an Access Project You can also use the query designer to edit an existing SQL statement. To do this, highlight the SQL statement, right-click on the highlighted selection, and choose Edit SQL from the shortcut menu. You can also click the Edit SQL button on the toolbar. Either method displays the highlighted text in a query designer dialog box where you can modify the text or check the SQL syntax using the syntax checker. Caution

Save your work often and keep backup copies of your text queries. (Notepad works great for this purpose.) The text editor does not have any undo features and can be very unforgiving if you make a mistake.

The most powerful query type that you can create in an Access project is the stored procedure. Thus far, you ve had a glimpse of what stored procedures can do by designing one using the query designer. To take full advantage of the capabilities of stored procedures, you must create them using the text editor. Here are some of the abilities that you have with a text stored procedure:

Execute other stored procedures and functions. You can make use of any available
Declare parameters and variables. You can input and output specific data as well as
declare variables that are referenced and changed within the stored procedure.
Use control-of-flow statements. Much like the statements available in Visual Basic
procedures, control-of-flow statements in stored procedures allow you to check for conditions, loop through statements multiple times, and trap errors.
Group multiple statements using transactions. You can make sure an entire group

of operations completes successfully by batching them inside a transaction and monitoring any errors. If any operation fails, you can ask SQL Server to roll back all changes made to the database within the transaction. Let s take the stored procedure you created in the query designer and rebuild it in the text editor. Along the way, you ll improve it by declaring variables, adding control-of-flow statements, including error trapping, and calling another stored procedure.
Beginning a New Stored Procedure in the Text Editor
Open the Contacts.adp sample project file. Select Queries on the Object bar of the Database window, click the New button on the Database window toolbar, and select Create Text Stored Procedure in the New Query dialog box (Figure 18-25). Click OK, and Access opens the text editor with some Transact-SQL code and comments already inserted, as shown in Figure 18-26 on the next page. 667

Figure 18-26. A new stored procedure in the text editor.
You can create a stored procedure using any text editing tool and import it into the Query Analyzer of SQL Server. In order for SQL Server to recognize that you are trying to create a stored procedure, you need to use the CREATE PROCEDURE statement followed by the name of the procedure in double quotes. Similarly, if you want to change an existing stored procedure, you use the ALTER PROCEDURE statement followed by the name of the procedure you want to alter. (You don t need to use quotes when referring to an existing procedure unless the procedure name contains blanks or special characters.) If you were to save this procedure, close it, and reopen it in Access, you would see the ALTER statement instead of the CREATE statement, because you would be altering an existing procedure. The /* and */ symbols mark the beginning and end of a block of comments. Anything written within those symbols is designated as a comment and is there only to provide information about the purpose of the stored procedure. You can also enter a single-line comment by typing two hyphens (--) at its beginning. Here are a couple of examples:
/* This is a multiple-line block of text that describes a section of the stored procedure */ -- This is a single-line comment
