A method, system and computer program product includes receiving and parsing an SQL query, identifying at least one common sub expression, or sub-query, or combination thereof, used multiple times within the SQL query, constructing for the at least one common sub expression, or sub-query, or combination thereof, a query execution plan that maintains as part of an initial result set a bit vector for a fact table, storing a result bit vector and an indicator that tracks a last valid tuple processed to produce the result bit vector when a TEMP operation is indicated in the query execution plan, reassessing a TEMP result in other portions of the query execution plan, priming a list of tuples using the TEMP result, and retrieving respective columns for further processing in the query execution plan.
