Re: SQL UDF From RPG Program

The issue is that literals are VARCHAR and you've defined the parm as CHAR.

Using CHAR() around the literal is one fix, the other is to change the
program to accept VARCHAR, ie. VARYING, parameters.

This bites everybody at least once, check the archives :)

Actually, life is better now at v5r4 as the DB will automatically
convert literals in most cases.

What error are you getting and when are you getting it?

The message was "GETZIPDIST in DMIPGMS type *N not found".  I finally
managed to get when the function working via a service program call.  My
problem was the literal value I was passing in my call to the function.

The following code doesn't work:

SELECT ZIPCODE FROM ZIPCENTER WHERE GETZIPDIST(ZIPCOD, '12345') <= 25

But this code DOES work:

SELECT ZIPCODE FROM ZIPCENTER WHERE GETZIPDIST(ZIPCOD, CHAR('12345')) <= 25

I haven't had much experience with SQL UDF's on IBM i, so maybe the
external UDFs won't play well with literal values.  Using the CHAR function
isn't a big deal, but out of curiosity, is there a way to define the UDF so
the literal would be accepted without casting it?
