SYMPTOM:
When defining a column expression in Query Builder with a Database Specific function such as with a 'CASE' statement, the following error is displayed when validating the expression in Strategy Developer 10.x:
The function `CASE` is not supported in DBMS DB2 UDB V8.1/8.2 for Unix/Windows
Note: This particular error message is only produced in the circumstance when a 'CASE' statement is used with a DB2 database.
CAUSE:
When using database-specific functions within query builder, users still need to use the Applysimple pass-through function in order to generate the correct SQL.
ACTION:
Utilize a pass-through function such as an ApplySimple, and include it in the definition of the column expression.
