Calculations in a WHERE clause involving double-byte character set (DBMS) columns that are defined as datetime values can return incorrect results.

This problem occurs when a DBMS datetime column is listed in the SELECT clause and the column is aliased. The alias prevents the column's type from being identified as a datetime value in the operation.

This problem has occurred in left and right outer joins when the calculation is performed in a WHERE clause.
