Error description

  • When query is attepted to match with a MQT whose definition has
no GB, and if the query has a redudant join pred that is added
internally by query rewrite (e.g. when query has pred T1.c1 =
T2.c1 and T2.c1 = T3.c1, query rewrite may add a redundant join
pred T1.c1 = T3.c1, called redCorPrd), and if redCorPrd pred is
correlated, and if the MQT defintion includes the local table of
redCorPrd, the query may crash with the trap stack.
