Re: ORACLE*FORMS and stored functions

Hello there,
we can use a stored function in a SQL stmt provided it is in a package and if you want to use it the function should not do any updations to the database.
the package creation script may look like this...
create package my_pack is
function compute(....) return ....;
pragma restrict_references(COMPUTE, WNPS, WNDS);
end my_pack;
I heard, this is to say this function does not update any tables.
Hope this helps.

: Note how the function was called outside of the Select statement.
