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

ANSI compliant, without cursor

PRINT ('1.a. Delete stored procedures ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO
DECLARE @procedure NVARCHAR(max)
DECLARE @n CHAR(1)
SET @n = CHAR(10)
SELECT @procedure = isnull( @procedure + @n, '' ) +
'DROP PROCEDURE [' + schema_name(schema_id) + '].[' + name + ']'
FROM sys.procedures

EXEC sp_executesql @procedure
PRINT ('1.b. Stored procedures deleted ' + CONVERT( VARCHAR(19), GETDATE(), 121));
GO

Answer 2

I think this is the simplest way:

DECLARE @sql VARCHAR(MAX)='';

SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects 
WHERE type = 'p' AND  is_ms_shipped = 0

exec(@sql);

Answer 3

To get drop statements for all stored procedures in a database SELECT 'DROP PROCEDURE' + ' ' + F.NAME + ';' FROM SYS.objects AS F where type='P'

Answer 4

Something like (Found at Delete All Procedures from a database using a Stored procedure in SQL Server).

Just so by the way, this seems like a VERY dangerous thing to do, just a thought...

declare @procName varchar(500)
declare cur cursor 

for select [name] from sys.objects where type = 'p'
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec('drop procedure [' + @procName + ']')
    fetch next from cur into @procName
end
close cur
deallocate cur

Answer 5

DECLARE @sql VARCHAR(MAX)
SET @sql=''
SELECT @sql=@sql+'drop procedure ['+name +'];' FROM sys.objects
WHERE type = 'p' AND  is_ms_shipped = 0
exec(@sql);

Answer 6

Try this:

DECLARE @sql NVARCHAR(MAX) = N'';

SELECT @sql += N'DROP PROCEDURE dbo.'
  + QUOTENAME(name) + ';
' FROM sys.procedures
WHERE name LIKE N'spname%'
AND SCHEMA_NAME(schema_id) = N'dbo';

EXEC sp_executesql @sql;
