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

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

IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OB开发者_StackOverflowJECT_ID(N'[dbo].[MySP]')   
  AND type in (N'P', N'PC'))  
DROP PROCEDURE [dbo].[MySP] 

Is there a way to drop them all at once, or maybe in a loop?

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

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

1. In the Object Explorer pane, select the Stored Procedures folder.
2. Press F7 (or from the main menu, choose View > Object Explorer Details).
3. Select all procedures except the System Table.
4. Press Delete button and select OK.

You can delete Tables or Views in the same manner.

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

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);

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

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);

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;

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

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;

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)

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

ANSI compliant, without cursor

PRINT ('1.a. Delete stored procedures ' + CONVERT( VARCHAR(19), GETDATE(), 121));

DECLARE @procedure NVARCHAR(max)
DECLARE @n CHAR(1)

SELECT @procedure = isnull( @procedure + @n, '' ) +

Try this:

open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec( @procName )
    fetch next from cur into @procName

close cur
deallocate cur
