I want to be able to programmatically (in T-SQL) check if a specific linked server already exists for my current server and database (so that if the link doesn't exist yet, I can create it). I tried stuff like this:
IF OBJECT_ID('myserver\devdb_1') IS NULL
BEGIN
PRINT 'Does not exist, need to create link'
EXEC master.dbo.sp_addlinkedserver @server = N'myserver\devdb_1',
@srvproduct=N'SQL Server'
END
ELSE
PRINT 'Link already exists'
But the OBJECT_ID test always returns null, even if the link already exists. Any way to do this check in T-SQL, so that the rest of my code can assume the link always exists?
Check in sys.servers
:
if not exists(select * from sys.servers where name = N'myserver\devdb_1')
