Hi

I am trying to execute an update statement against a table available through linked server

(used sp_addlinkedserver and sp_addlinkedsrvlogin to configure linked server).

But to execute this query it takes more than 30 minutes, where as when executed on the

remote server directly takes only 1 second.

Query :

Update [RemoteServer].DATABASEName.dbo.TableAA
Set Fa_Enigma_Id = Cu_Customer_Id
From TableBB
Where TableAA.Fa_facility_No = TableBB.cu_gatsid
And TableAA.Fa_Enigma_Id IS NULL
And TableAA.ZZ_Location = 'UK'

Please note that TableAA is a table available on remote server and TableBB is a table in

local database where the query is executed.

Further Info, TableAA has 6000 records and TableBB has only 393 records.
Please help to improve the performance.

Thanks & Regards

Venkat

You can run SQL Profiler on both machines and find out which server takes more time to execute the query. In that way you can narrow down your problem.

Venkat,
Furthermore, the SQL query times are suspect because sometimes, the application will become un-hung if it is left alone for a few minutes. Please review the following info:

Many Thanks Ned for your help,
I tried profilers option and then realised that updating remote tables (even one record) is causing lot of delays.
so we changed the logic to have procedures in remote server to update.

Thanks Once again
