>Table A with indexes on tCreated, iStopCode, iMachineID. In a view left outer joined to TableB on iCode into the iID PK for the table. TableA 1 million records, TableB 60 records. Filtered on iMachineID=?piMachine and iCode > 0, Setting view order to tCreated DESCENDING and have TopN set to 20 records. The ?piMachineID should filter TableA to about 10K records. Basically I'm trying to get the last 20 records for iCode>0.

I would say that neither of them. Still, for both of them, the index must be created. Did you use the sys(3054) to see the optimization status? Is an outer join optimizable?

I assume you also have an index on iCode and deleted().
