Re: First SQL UDF

Hi Craig,

How about

set alpha =
Substr(Space(7), 1, 7 - Length(Trim(Char(numb)))) Concat
Trim(Char(numb));


I'm assuming that when you said it returns null values, that it's actually returning blanks.

I am trying to write my first SQL UDF converting a numeric value that is 8.0
to an alpha value that is 7 long right justified with no leading zeros.


The code currently used to tie files together in RPG is:

EvalR Work7 = %EditC(AiOrder:'Z')


In SQL I am using:

Substr(Space(7), 1, 7 - Length(Trim(Char(AiOrder)))) Concat

Char(AiOrder)

I tried creating a UDF to accomplish the above to shorten internal SQL Code.

Obviously I am doing something wrong. The Function does get created but
when I try to run, all I get is null values.



Create function CharOrder
(numb DEC)
Returns char
language SQL
returns null on null input
begin
declare numb dec(8);
declare alpha char(7);
set alpha =
Substr(Space(7), 1, 7 - Length(Trim(Char(numb)))) Concat
Char(numb);
Return alpha;
End


TIA,
