sp_ServerStatus

,

Have you ever wanted to check that a server exists before using it. Here is a solution that use SQLDMO from within TSQL to get the status of a SQL Server service. It also works for 2000 instances.
I have named it sp_ServerStatus for it to be based in master.

This returns the status integer and a text description through OUTPUT properties of the SP.

Example

DECLARE @s int, @t varchar(100)
exec sp_ServerStatus 'MySQLServer\instance1',@s output, @t output
select @s, @t

DROP PROCEDURE dbo.sp_ServerStatus
go
CREATE PROCEDURE dbo.sp_ServerStatus
