  • Closed as program error.

Error description

  • Description:
    DB2 used to not consider routing left or right OUTER JOIN query
    construct to MQT unless this MQT is SELECT FROM a base table
    without any predicate. This fix relax the constraint of no
    presence of any predicate. Since MQT is dependant on a single
    base table, the predicate must be local predicate.
