Status: Geschlossen |
QUERIES USING OUTER JOINS AND SCALAR SUBQUERY RUNS SIGNIFICANTLY SLOWER COMPARING TO OUTER JOINS AND LOCAL PREDICATES |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problembeschreibung: |
When scalar subquery is used in a WHERE clause on a series of
Outer Joins, the scalar subquery is similar to a local predicate
that should be applied at the access of the table under the
Outer Joins
to early filter the rows. |
