Allan,

Why don't you try a Regular Expression?

SELECT REGEXP_SUBSTR(searchString', '\D+') FROM SYSIBM.SYSDUMMY1

will get you back at least a one-char non-empty string of anything that is
NOT a digit in searchString. This result is NOT a number.
If searchString has only digits, this query will return NULL so this way
you know it is a number. The "pattern" to search for '\D+' will match at
least one non-digit character.

This query will detect only integer numeric expressions. If you want to
detect a decimal point or comma, you would have to try another search
pattern, and that makes it a little more complicated, but not impossible.

HTH.

Javier Sanchez.

I was told about te SQL TRY_CAST - but that looks to be available from

Hi everyone
We are on V7r3
Current on all ptf's and TFR's(?)
I may not be remembering this correctly - but wasn't there something

recently released , for SQL and/or RPG, that could be used to determine if
a string is numeric?

I do already have a method but if my memory is correct, would like to

use that new bif/command

If my memory is failing me (no surprise there), then I will resort to

what I have used in the past

As always - all replies gratefully accepted
