Transact-SQL syntax conventions
Syntax
-- Syntax for SQL Server and Azure SQL Database
DROP { PROC | PROCEDURE } [ IF EXISTS ] { [ schema_name. ] procedure } [ ,...n ]
-- Syntax for Azure Synapse Analytics and Parallel Data Warehouse and Microsoft Fabric
DROP { PROC | PROCEDURE } { [ schema_name. ] procedure_name }
Note
To view Transact-SQL syntax for SQL Server 2014 (12.x) and earlier versions, see Previous versions documentation.
Arguments
IF EXISTS
Applies to: SQL Server ( SQL Server 2016 (13.x) through current version).
Conditionally drops the procedure only if it already exists.
schema_name
The name of the schema to which the procedure belongs. A server name or database name cannot be specified.
procedure
The name of the stored procedure or stored procedure group to be removed. Individual procedures within a numbered procedure group cannot be dropped; the whole procedure group is dropped.
Best Practices
Before removing any stored procedure, check for dependent objects and modify these objects accordingly. Dropping a stored procedure can cause dependent objects and scripts to fail when these objects are not updated. For more information, see View the Dependencies of a Stored Procedure
Metadata
To display a list of existing procedures, query the sys.objects catalog view. To display the procedure definition, query the sys.sql_modules catalog view.
Security
Permissions
Requires CONTROL permission on the procedure, or ALTER permission on the schema to which the procedure belongs, or membership in the db_ddladmin fixed server role.
Examples
The following example removes the dbo.uspMyProc
stored procedure in the current database.
DROP PROCEDURE dbo.uspMyProc;
GO
The following example removes several stored procedures in the current database.
DROP PROCEDURE dbo.uspGetSalesbyMonth, dbo.uspUpdateSalesQuotes, dbo.uspGetSalesByYear;
The following example removes the dbo.uspMyProc
stored procedure if it exists but does not cause an error if the procedure does not exist. This syntax is new in SQL Server 2016 (13.x).
DROP PROCEDURE IF EXISTS dbo.uspMyProc;
GO
