DB2 FOR LUW / DB2FORLUW / 970 - DB2

With the number_compat database configuration parameter set to 
ON, creation of a refresh immediate MQT that 
references a distinct type as a group by column may succeed 
unexpectedly, while subsequent updates on the base table of the 
MQT may result in SQL0901N. SQL20058N rc 6 should have been 
returned during table creation.
