Once defined by the CREATE PROCEDURE statement, a stored procedure can be used. An application program may request execution of the stored procedure, using the appropriate SQL statement. Another stored procedure may call it to perform a specific function. The stored procedure may also be invoked through an interactive SQL interface. The various SQL dialects differ in the specific syntax used to call a stored procedure. Here is a call to the ADD_CUST procedure in the PL/SQL dialect:

The ADD_CUST procedure in Informix SPL
The values to be used for the procedure s parameters are specified, in order, in a list that is enclosed by parentheses. When called from within another procedure or a trigger, the EXECUTE statement may be omitted, and the call becomes simply:
ADD_CUST( XYZ Corporation , 2137, 30000.00, 50000.00, 103, Chicago )
In the Transact-SQL dialect, the call to the stored procedure becomes:
EXECUTE ADD_CUST XYZ Corporation , 2137, 30000.00, 50000.00, 103, Chicago
SQL: The Complete Reference
The parentheses aren t required, and the values to be used for parameters again form a comma-separated list. The keyword EXECUTE can be abbreviated to EXEC, and the parameter names can be explicitly specified in the call, allowing you to specify the parameter values in any order you wish. Here is an alternative, equivalent Transact-SQL call to the ADD_CUST stored procedure:
EXEC ADD_CUST @C_NAME @C_NUM @CRED_LIM @C_OFFC @C_REP @TGT_SLS = = = = = = XYZ Corporation , 2137, 30000.00, Chicago , 103, 50000.00
The Informix SPL form of the same EXECUTE command is:
EXECUTE PROCEDURE ADD_CUST( XYZ Corporation , 2137, 30000.00, 50000.00, 103, Chicago )
Again, the parameters are enclosed in a comma-separated, parenthesized list. This form of the EXECUTE statement may be used in any context. For example, it may be used by an embedded SQL application program to invoke a stored procedure. Within a stored procedure itself, another stored procedure can be called using this equivalent statement:
CALL ADD_CUST( XYZ Corporation , 2137, 30000.00, 50000.00,103, Chicago )
Stored Procedure Variables
In addition to the parameters passed into a stored procedure, it s often convenient or necessary to define other variables to hold intermediate values during the procedure s execution. All stored procedure dialects provide this capability. Usually, the variables are declared at the beginning of the procedure body, just after the procedure header and before the list of SQL statements. The data types of the variables can be any of the SQL data types supported as column data types by the DBMS. Figure 20-4 shows a simple Transact-SQL stored procedure fragment that computes the total outstanding order amount for a specific customer number, and sets up one of two messages depending on whether the total order amount is over or under $30,000. Note that Transact-SQL local variable names, like parameter names, begin with an at sign (@). The DECLARE statement declares the local variables for this procedure. In this case, there are two variables: one with the MONEY data type and one VARCHAR. In Transact-SQL, the SELECT statement assumes the additional function of assigning values to variables. A simple form of this use of SELECT is the assignment of the message text:
