| Produkt: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |

Complex queries referencing column organized tables may
experience slow prepare time when the queries involve common
table expressions, views or nested sub-selects with multiple
levels and include local predicates or subqueries referencing
the nested objects. |
