TRANSITIVE LOCAL PREDICATES ACROSS MULTIPLE JOINS |
摘要 |
In an example, a transitive local predicates may be inferred across multiple joins, wherein the multiple outer joins include multiple outer joins. A query connecting tables by the multiple joins is analyzed. A local predicate may then be identified from the analyzed query and may be determined to be either a where-clause local predicate or an on-clause local predicate. Accordingly, a transitive local predicate may be inferred across a selection of the tables based on the determination. |
