When were OLEDB based linked servers added to SQL Server? I guess what I'm asking is in which version of SQL Server were linked servers added to SQL Server?
I believe this was introduced in SQL 7. If memory serves me right, I was able to access a SQL 6.5 server from a SQL 7 server, but I could not access SQL 6.5 from/to another SQL 6.5 (I don't think the sp_addlinkedserver stored procedure existed prior to SQL 7).
