Using Query Analyser To Create A Stored Procedure

Experts;

I am use the Query analyser to buidl a Master Stored Procedure that would go through the Stored Procedures in the DB to recreate them again

I am tesing this in the Query Analyser

This is the section of my code to create on of the Stored Procedures in the DataBase


select @SQL = 'if exists (select * from dbo.sysobjects where id = object_id(N''[dbo].[IMGSAttributes'+@TableName+']'') and OBJECTPROPERTY(id, N''IsProcedure'') = 1)'
select @SQL = @SQL + char(13) + char(10) + 'drop procedure [dbo].[IMGSAttributes'+@TableName+']'
select @SQL = @SQL + char(13) + char(10) + 'GO'+ char(13) + char(10) +'SET QUOTED_IDENTIFIER ON'+ char(13) + char(10) +'GO'+ char(13) + char(10) +'SET ANSI_NULLS ON'+ char(13) + char(10) +'GO'+ char(13) + char(10) +'CREATE PROCEDURE dbo.IMGSAttributes'+@TableName
select @SQL = @SQL + char(13) + char(10) + '@pIndex varchar(50)'+ char(13) + char(10) + 'AS'+ char(13) + char(10) +'SET CONCAT_NULL_YIELDS_NULL OFF'+ char(13) + char(10) +'Select '+@PrimaryColumName + ' as GMKey,'+''''+@TableName +''' as TABLENAME, '+@ColText
select @SQL = @SQL + ' from '+@TableName+' where ' +@PrimaryColumName +' = @pIndex'
select @SQL = @SQL + char(13) + char(10) + 'RETURN '+ char(13) + char(10) +'GO '+ char(13) + char(10) +' SET QUOTED_IDENTIFIER OFF '+ char(13) + char(10) +'GO'+ char(13) + char(10) +'SET ANSI_NULLS ON '+ char(13) + char(10) +'GO'

exec(@SQL)
