I'm using a query that joins two perf counters in one table, based on the Computer name.
I started to think on how to add a third counter and join it to the same table on the same query, and I wondered if it wouldn't be more efficient to restrict the results beforehand instead of doing a join of all results.
So that would mean bringing the perf counters where Computer == "Computer names values that are on the Computer column of the previous table"
Is that possible?
And, if not, how can I join more than two tables?
Thanks in advance
