How to drop all stored procedures at once in SQL Server database?

Question

Currently we use separate a drop statements for each stored procedure in the script file:

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N\'[         


        

Answer 1

By mixing the cursor and system procedure, we would have a optimized solution, as follow:

DECLARE DelAllProcedures CURSOR
FOR
    SELECT name AS procedure_name 
    FROM sys.procedures;
OPEN DelAllProcedures
DECLARE @ProcName VARCHAR(100)
FETCH NEXT 
FROM DelAllProcedures
INTO @ProcName
WHILE @@FETCH_STATUS!=-1
BEGIN 
    DECLARE @command VARCHAR(100)
    SET @command=''
    SET @command=@command+'DROP PROCEDURE '+@ProcName
    --DROP PROCEDURE  @ProcName
    EXECUTE (@command)
    FETCH NEXT 
    FROM DelAllProcedures
    INTO @ProcName
END
CLOSE DelAllProcedures
DEALLOCATE DelAllProcedures

Answer 2

Try this, it work for me

DECLARE @spname sysname;
DECLARE SPCursor CURSOR FOR
SELECT SCHEMA_NAME(schema_id) + '.' + name
FROM sys.objects
WHERE type = 'P';
OPEN SPCursor;
FETCH NEXT FROM SPCursor INTO @spname;
WHILE @@FETCH_STATUS = 0
BEGIN
EXEC('DROP PROCEDURE ' + @spname);
FETCH NEXT FROM SPCursor INTO @spname;
END
CLOSE SPCursor;
DEALLOCATE SPCursor;
