Collation Checker Version 2

,

this is version 2 of a quick sproc I put together to do various collation checks.

now excludes offline databases (using state <> 6 from sys.databases)

checks are :-

databases that have different collations from server
databases that have different collations of columns within
databases that have column collations different from database collation

run by :-

exec sp_collation_checker

USE [master]
GO
/****** Object: StoredProcedure [dbo].[sp_collation_checker] Script Date: 07/13/2007 15:58:51 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
drop procedure sp_collation_checker
go
create procedure [dbo].[sp_collation_checker]
as
-- this procedure checks the collation as follows :-
-- databases that have different collations from server
-- databases that have different collations of columns within
-- databases that have column collations different from database collation
--
-- it returns some text with a description of the issue e.g :-
-- "there are no databases that have a different collation from master"
-- "the pgr_test database has more than one collation"
-- "the col2 column collation (Latin1_General_CS_AS) in the pgr_test database does not match 
-- the database collation (Latin1_General_CI_AS)"
--
-- this procedure has been tested on sql server 2000 sp4 and SQL Server 2005 sp2
-- any problems email pgr_consulting @ yahoo.com
