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

Try this:

declare @procName varchar(500)
declare cur cursor 

for SELECT 'DROP PROCEDURE [' + SCHEMA_NAME(p.schema_id) + '].[' + p.NAME + ']'
FROM sys.procedures p 
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec( @procName )
    fetch next from cur into @procName
end
close cur
deallocate cur

Answer 2

create below stored procedure in your db(from which db u want to delete sp's)

then right click on that procedure - click on Execute Stored Procedure..

then click ok.

create Procedure [dbo].[DeleteAllProcedures]
As 
declare @schemaName varchar(500)    
declare @procName varchar(500)
declare cur cursor
for select s.Name, p.Name from sys.procedures p
INNER JOIN sys.schemas s ON p.schema_id = s.schema_id
WHERE p.type = 'P' and is_ms_shipped = 0 and p.name not like 'sp[_]%diagram%'
ORDER BY s.Name, p.Name
open cur

fetch next from cur into @schemaName,@procName
while @@fetch_status = 0
begin
if @procName <> 'DeleteAllProcedures'
exec('drop procedure ' + @schemaName + '.' + @procName)
fetch next from cur into @schemaName,@procName
end
close cur
deallocate cur

Answer 3

ANSI compliant, without cursor

DECLARE @SQL national character varying(MAX) 
SET @SQL= ''

SELECT @SQL= @SQL+ N'DROP PROCEDURE "' + REPLACE(SPECIFIC_SCHEMA, N'"', N'""') + N'"."' + REPLACE(SPECIFIC_NAME, N'"', N'""') + N'"; '
FROM INFORMATION_SCHEMA.ROUTINES 

WHERE (1=1) 
AND ROUTINE_TYPE = 'PROCEDURE' 
AND ROUTINE_NAME NOT IN 
(
     'dt_adduserobject'
    ,'dt_droppropertiesbyid'
    ,'dt_dropuserobjectbyid'
    ,'dt_generateansiname'
    ,'dt_getobjwithprop'
    ,'dt_getobjwithprop_u'
    ,'dt_getpropertiesbyid'
    ,'dt_getpropertiesbyid_u'
    ,'dt_setpropertybyid'
    ,'dt_setpropertybyid_u'
    ,'dt_verstamp006'
    ,'dt_verstamp007'

    ,'sp_helpdiagrams'
    ,'sp_creatediagram'
    ,'sp_alterdiagram'
    ,'sp_renamediagram'
    ,'sp_dropdiagram'

    ,'sp_helpdiagramdefinition'
    ,'fn_diagramobjects'
    ,'sp_upgraddiagrams'
) 


ORDER BY SPECIFIC_NAME 


-- PRINT @SQL
EXEC(@SQL) 

Without cursor, non-ansi compliant:

DECLARE @sql NVARCHAR(MAX) = N''
, @lineFeed NVARCHAR(2) = CHAR(13) + CHAR(10) ;

SELECT @sql = @sql + N'DROP PROCEDURE ' + QUOTENAME(SPECIFIC_SCHEMA) + N'.' + QUOTENAME(SPECIFIC_NAME) + N';' + @lineFeed
FROM INFORMATION_SCHEMA.ROUTINES 
WHERE ROUTINE_TYPE = 'PROCEDURE' 
-- AND SPECIFIC_NAME LIKE 'sp[_]RPT[_]%'


AND ROUTINE_NAME NOT IN 
( 
    SELECT name FROM sys.procedures WHERE is_ms_shipped <> 0 
) 


ORDER BY SPECIFIC_NAME 


-- PRINT @sql 
EXECUTE(@sql)

Answer 4

1. Click on Stored Procedures Tab
2. Press f7 to Display All Stored Procedures
3. Select All Procedure By Ctrl + A except System Table
4. Press Delete button and Click OK.

You can Delete Table as well as View in same manner.

Answer 5

DECLARE @DeleteProcCommand NVARCHAR(500)

DECLARE Syntax_Cursor CURSOR
FOR
SELECT 'DROP PROCEDURE ' + p.NAME
FROM sys.procedures p

OPEN Syntax_Cursor

FETCH NEXT FROM Syntax_Cursor

INTO @DeleteProcCommand

WHILE (@@FETCH_STATUS = 0)
BEGIN

EXEC (@DeleteProcCommand)

FETCH NEXT FROM Syntax_Cursor
INTO @DeleteProcCommand

END

CLOSE Syntax_Cursor

DEALLOCATE Syntax_Cursor

Answer 6

I would prefer to do it this way:

• first generate the list of stored procedures to drop by inspecting the system catalog view:

  SELECT 'DROP PROCEDURE [' + SCHEMA_NAME(p.schema_id) + '].[' + p.NAME + '];'
  FROM sys.procedures p 
  

  This generates a list of DROP PROCEDURE statements in your SSMS output window.

• copy that list into a new query window, and possibly adapt it / change it and then execute it

No messy and slow cursors, gives you the ability to check and double-check your list of procedure to be dropped before you actually drop it
