RE: Using SQL UDF in SQLRPGLE program gets decimal data error

["Tyler, Matt" <mattt@xxxxxxxxxxxxxx>]

Peter,
        I also noticed that the UDF definition specifies that the input
parameters are of DEC() type which equates to a PACKED in RPG.  Try using
NUM() (NUMERIC=ZONED) instead since you are only using fields that are
zoned.


Thank you,

Hi Matt,

You're making sense, in fact there's an APAR about getting an MCH1202 when
the UDF returns NULL and the receiving variable has not been initialized,
e.g.

    c            eval    x = TestUDF(parm1:parm2)

if TestUDF returns NULL, and x is an uninitialized numeric field, you'll get
a decimal data error.  However, in my case, the receiving variable has been
initialized.

Thanks for the reply!
