SQL0437W might be induced by runstats in databases that use locale-sensitive UCA-based collations | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
In databases that use locale-sensitive UCA-based collations, if there is a string column that is longer than 66 bytes, and this column is a leading column of an index, then the colcard that is reported by runstats can be less than the number of frequent values. This can lead to the following SQL0437W warning when DB2 compiles a query that have predicates on the column: SQL0437W Performance of this complex query might be sub-optimal. Reason code: "6".
