Hi

I am trying to check if some table exists in linked server.
The flow is this:
1.check if Linked Server Exists
2.Check if Needed DB exists
3.Check if needed table exists

Here the script:

IF EXISTS (SELECT 1 FROM [master].[dbo].[sysservers] WHERE srvname = 'LinkedServerName')

BEGIN
IF EXISTS(SELECT 1 FROM [LinkedServerName].[master].[dbo].[sysdatabases] WHERE [name]='DBNAME')

BEGIN
IF EXISTS (SELECT 1 FROM [LinkedServerName].[DBNAME].[dbo].[sysobjects] AS sysobjcts WHERE [sysobjcts].[name] ='TableName' AND [sysobjcts].[xtype]='U')

PRINT 'OK'
END
END

The problem occurs when the needed DB ('DBNAME') not exists in the Linked Server.
and i get the following error:

Server: Msg 7314, Level 16, State 1, Line 4
OLE DB provider 'LinkedServerName' does not contain table '"DBNAME"."dbo"."sysobjects"'. The table either does not exist or the current user does not have permissions on that table.
OLE DB error trace [Non-interface error: OLE DB provider does not contain the table: ProviderName='LinkedServerName', TableName='"DBNAME"."dbo"."sysobjects"'].

How can i check if table exists in linked server?

Thanks

Hi,
try to build functions for checking if the wanted object exists and use the returnvalue of each function to make your controlflow.
It's because, i think, the parser is not looking at your if-statement at parse-time and then the not existing DBNAME always results in an error.

OK,

Its working,
But instead Function,I created Stored Procedure.
UDF cannot be called in Linked Server.

Thanks
