Delete all stored procedures in a specific SQL Server schema - sql-server

Question

I have hundreds of procedures auto generated by DataSync.
I don't have the time and sense to delete them manually.
They all start with DataSync.
Is there a way to delete all stored procedures where the name start with DataSync.?

Answer 1

Use the information_schema.routines (which is fairly standard across RDBMSs such as MSSQL,Mysql):
If your proc names start "DataSync." then they are probably in a schema, so you can find them with:
select
'DROP PROCEDURE [' + routine_schema + '].[' + routine_name + ']'
from
information_schema.routines where routine_schema = 'DataSync' and routine_type = 'PROCEDURE'
If your proc names start "DataSync" then you can find them with:
select
'DROP PROCEDURE [' + routine_schema + '].[' + routine_name + ']'
from
information_schema.routines where routine_name like 'DataSync%' and routine_type = 'PROCEDURE'
If you wanted to execute all these drop statements, you can build a single execute using FOR XML PATH as follows:
declare #sql varchar(max)
set #sql = (
select
'DROP PROCEDURE [' + routine_schema + '].[' + routine_name + '] '
from
information_schema.routines where routine_schema = 'DataSync' and routine_type = 'PROCEDURE'
FOR XML PATH ('')
)
exec (#sql)

Assuming you mean SQL Server when you specify "SQL" - then the easiest way is this: run this query:
SELECT
name,
DropCmd = 'DROP PROCEDURE DataSync.' + name
FROM sys.procedures
WHERE
schema_id = SCHEMA_ID('DataSync')
and the even "lazier" version would be to use a cursor to do this automatically for you:
DECLARE DropSpCursor CURSOR FAST_FORWARD FOR
SELECT
name
FROM sys.procedures
WHERE schema_id = SCHEMA_ID('DataSync')
DECLARE #StoredProcName sysname
DECLARE #DropStatement NVARCHAR(1000)
OPEN DropSpCursor
FETCH NEXT FROM DropSpCursor INTO #StoredProcName, #SchemaName
WHILE (##fetch_status <> -1)
BEGIN
IF (##fetch_status <> -2)
BEGIN
SET #DropStatement = N'DROP PROCEDURE DataSync.' + #StoredProcName
EXEC(#DropStatement)
END
FETCH NEXT FROM DropSpCursor INTO #StoredProcName
END
CLOSE DropSpCursor
DEALLOCATE DropSpCursor

Answer 3

No need for XML or loops:
declare #sql varchar(max) = ''
select #sql += 'drop procedure [' + routine_schema + '].[' + routine_name + '];'
from information_schema.routines where routine_schema = 'DataSync' and routine_type = 'PROCEDURE'
exec(#sql)

Answer 4

DECLARE #name AS VARCHAR(max)
DECLARE MyCursor CURSOR FAST_FORWARD READ_ONLY FOR
SELECT name FROM sys.objects WHERE type='P' AND schema_id=SCHEMA_ID('DataSync')
OPEN MyCursor
FETCH NEXT FROM MyCursor INTO #name
WHILE ##FETCH_STATUS = 0
BEGIN
EXEC('DROP PROCEDURE DataSync.' + #name)
FETCH NEXT FROM MyCursor INTO #name
END
CLOSE MyCursor
DEALLOCATE MyCursor
EDIT: changed where clause since it turned out DataSync is a schema name.

Answer 5

I've been using this short script to clear all SPs from a given schema (when using SQL Server). It iterates direct sys.procedures.
DECLARE #schema VARCHAR(100)
SET #schema = 'DataSync'
DECLARE #CurrentStatement AS VARCHAR(MAX)
SET #CurrentStatement = (SELECT TOP(1) 'DROP PROCEDURE [' + #schema + '].[' + name + ']'
FROM sys.procedures
WHERE schema_id = SCHEMA_ID(#schema))
WHILE #CurrentStatement IS NOT NULL
BEGIN
EXEC (#CurrentStatement)
SET #CurrentStatement = (SELECT TOP(1) 'DROP PROCEDURE [' + #schema + '].[' + name + ']'
FROM sys.procedures
WHERE schema_id = SCHEMA_ID(#schema))
END
The premise is very similar to the answer provided by marc_s; however doesn't utilize a cursor for the iteration. While there's a record in sys.procedures matching our schema, we need to delete it.

try this with sql2012 or above,
this will be help to delete all objects by selected schema
keep 'P' and remove rest for stored procedure only (o.type IN ('P')
DECLARE #MySchemaName VARCHAR(50)='dbo', #sql VARCHAR(MAX)='';
DECLARE #SchemaName VARCHAR(255), #ObjectName VARCHAR(255), #ObjectType VARCHAR(255), #ObjectDesc VARCHAR(255), #Category INT;
DECLARE cur CURSOR FOR
SELECT (s.name)SchemaName, (o.name)ObjectName, (o.type)ObjectType,(o.type_desc)ObjectDesc,(so.category)Category
FROM sys.objects o
INNER JOIN sys.schemas s ON o.schema_id = s.schema_id
INNER JOIN sysobjects so ON so.name=o.name
WHERE s.name = #MySchemaName
AND so.category=0
AND o.type IN ('P','PC','U','V','FN','IF','TF','FS','FT','PK','TT')
OPEN cur
FETCH NEXT FROM cur INTO #SchemaName,#ObjectName,#ObjectType,#ObjectDesc,#Category
SET #sql='';
WHILE ##FETCH_STATUS = 0 BEGIN
IF #ObjectType IN('FN', 'IF', 'TF', 'FS', 'FT') SET #sql=#sql+'Drop Function '+#MySchemaName+'.'+#ObjectName+CHAR(13)
IF #ObjectType IN('V') SET #sql=#sql+'Drop View '+#MySchemaName+'.'+#ObjectName+CHAR(13)
IF #ObjectType IN('P') SET #sql=#sql+'Drop Procedure '+#MySchemaName+'.'+#ObjectName+CHAR(13)
IF #ObjectType IN('U') SET #sql=#sql+'Drop Table '+#MySchemaName+'.'+#ObjectName+CHAR(13)
--PRINT #ObjectName + ' | ' + #ObjectType
FETCH NEXT FROM cur INTO #SchemaName,#ObjectName,#ObjectType,#ObjectDesc,#Category
END
CLOSE cur;
DEALLOCATE cur;
SET #sql=#sql+CASE WHEN LEN(#sql)>0 THEN 'Drop Schema '+#MySchemaName+CHAR(13) ELSE '' END
PRINT #sql
EXECUTE (#sql)
