Efficient technique to defer large object access with intermediate results

摘要

A method, apparatus, and article of manufacture for a computer implemented technique for deferring large object access with intermediate results. A query is executed in a database stored on a data storage device connected to a computer. A control structure representing an expression in the query is generated. An intermediate result is generated by retrieving data for the query that is not represented by the control structure. Then, a result table is built using the processed intermediate result and the control structure.
