Status: Closed |
SQL0437W might be induced by runstats in databases that use locale-sensitive UCA-based collations |
| product: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problem description: |
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". SQLSTATE=01602 |
