Hi user7417334,
You cannot use any formulas in the presentation layer (not that I know of). But you can definitely use oracle database functions in the BMM layer.
You want to use the EVALUATE function. It works like this:
e.x. EVALUATE( 'TO_DATE(%1,%2)' AS DATE, '12/31/2009', 'MM/DD/YYYY')
Generic Version: EVALUATE( '<FUNC>' AS <DATATYPE>, VALUE1,VALUE2,etc)
FUNC) Is the syntax for the function you are calling. Any parameters have to be replaced by %<number>, where number refers to the order in which you specify your parameters.
DATATYPE) The datatype that the function will evaluate to. In this case, DATE.
VALUE1) The latter part of the formula is a comma separated list of all the parameters used in the function. In this case, it's the date I want to cast
VALUE2) This is the second parameter. You need as many as you referenced in your function. In this case, it's the date format.
Good luck and if you found this post useful, please award points!
