Hello all
I have the following cursor below (I have to admit I am not that strong with error handling or using cursors yet, but getting there). What I really need this cursor to do is keep running even if the linked server has no access (would like it to go to the next server that is stored in a list).
I put a comment where the code breaks. It has no problem adding the linked server, but when I try to run a sql statement (the "@sql") it retruns the following message and then stops. I would love for it to continue.
Anyone have any ideas?
Error message I am getting:
Server: Msg 17, Level 16, State 1, Line 1
SQL Server does not exist or access denied.

declare @sqlls varchar(1000)
declare @sql as varchar(1000)
declare @pLinkName varchar(100)
declare @pAction int
declare @database as varchar(50)
set @database = '.master.dbo.syslogins'
set @pLinkName = 'FindUsers'
set @pAction = '1'

Have you got a server called "FindUsers"??? That's where the error is on my machine...

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

My apologies. The "FindUsers" server is a linked server that is setup already. I believe if you set up a linked server to a server that you know is down then you should get the same error that I get.

Thanks for looking into this.
