Only the system administrator ( sa) can mark a procedure to execute automatically. Set, clear, and control automatic execution

Because the procedure is being executed by SQL Server instead of an application or user, there is nowhere for the result sets to go. This uses only one worker thread.ĭo not return any result sets from a procedure that is executed automatically. If you must execute multiple procedures at startup but do not need to execute them in parallel, make one procedure the startup procedure and have that procedure call the other procedures. There is no limit to the number of startup procedures you can have, but be aware that each consumes one worker thread while executing. Any error messages generated by the procedure are written to the SQL Server error log.

This makes sure that such a temporary table will always exist when tempdb is re-created during SQL Server startup.Ī procedure that is automatically executed operates with the same permissions as members of the sysadmin fixed server role. Another use for automatic execution is to have the procedure perform system or maintenance tasks in tempdb, such as creating a global temporary table. Setting up procedures to execute automatically can be useful for performing database maintenance operations or for having procedures run continuously as background processes. Procedures marked for automatic execution are executed every time SQL Server starts and the master database is recovered during that startup process. Or, if the nonqualified procedure name appears inside the body of another procedure definition, the schema that contains this other procedure is searched next. The caller's default schema if it is executed in a batch or in dynamic SQL. If a nonqualified user-defined procedure is specified, the Database Engine searches for the procedure in the following order: For information about specifying input and output parameters, see Specify Parameters. Notice that the procedure accepts one input parameter. The following example demonstrates the recommended method to execute a user-defined procedure. It also prevents executing the wrong procedure if a database has procedures with the same name in multiple schemas. This practice gives a small performance boost because the Database Engine does not have to search multiple schemas. When executing a user-defined procedure, we recommend qualifying the procedure name with the schema name. The following example demonstrates the recommended method of calling a system procedure. However, we recommend schema-qualifying all system procedure names with the sys schema name to prevent name conflicts. Because they logically appear in all user- and system- defined databases, they can be executed from any database without having to fully qualify the procedure name. System procedures begin with the prefix sp_. Recommendations Execute system stored procedures If a user-defined procedure has the same name as a system procedure, the user-defined procedure might not ever execute. To display the exact system procedure names, query the sys.system_objects and sys.system_parameters catalog views.

For example, this code will fail if executed in the context of a database that has a case-sensitive collation: EXEC SP_heLP - Will fail to resolve because SP_heLP does not equal sp_help For this reason, always use the exact case of system procedure names in procedure calls. The calling database collation is used when matching system procedure names. Before you begin Limitations and restrictions The procedure can be called and executed without the EXEC keyword if the procedure is the first statement in the Transact-SQL batch. When a procedure is called by an application or user, the Transact-SQL EXECUTE or EXEC keyword is explicitly stated in the call. The second approach is to set the procedure to run automatically when an instance of SQL Server starts. The first and most common approach is for an application or user to call the procedure. There are two different ways to execute a stored procedure.
