![]() 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. This article describes how to execute a stored procedure in SQL Server by using SQL Server Management Studio or Transact-SQL. I sample this using a really bad way by casting the XML to string and then doing a wildcard search however XML queries are not things most do every day and string wildcards are easy for everyone.Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Analytics Platform System (PDW) SELECTĪnd cast(qp.query_plan as nvarchar(max)) like '%loop%' ![]() ![]() The XML query plan (the first column in both queries), contains the XML of the execution plan allowing you, in SSMS to click on it and view the actual plans but also allows you to scan for things you do not like to have like index scan or "god forbid" table scans. Join sys.objects as so on so.=QP.objectid There is a lot more data to look at, like how often is a procedure executed according to query cache SELECT Looking at the plans on a production server with the statistics of the data in the production server may show a different plan then of a dev box with a smaller dataset.
