Queries with a MAX scalar function over a nullable column may 
not be routed to an MQT. 
 
A query of the form: 
           select max(col) from T ?     , where col is a 
nullable column 
may not be routed to a materialized query table (M) defined on 
base table T. 
 
The following will be observed in the diagnostic section of the 
access plan, where T is the base table of M: 
 
Diagnostic Details: 	EXP0062W  The following MQT or statistical 
view was 
			not eligible because one or more columns or 
			expressions referenced in the query were not found 
			in the MQT: <schema>.?M?.

expression that returns the same value as the column. 
 
For example, if col is a column of a numeric data type, 
modifying max(col) to max(col+0).
