gkodinov/kgeorge@magare.gmz d67cd9e8af Bug #31221: Optimizer incorrectly identifies impossible WHERE clause ...

No warning was generated when a TIMESTAMP with a non-zero time part
 was converted to a DATE value. This caused index lookup to assume
 that this is a valid conversion and was returning rows that match 
 a comparison between a TIMESTAMP value and a DATE keypart.
 Fixed by generating a warning on such a truncation.
