Re: Implicit cast on ORDER BY

Vern,
Not trying to be pedantic but who is Julian? Was it just an autocorrect of
Justin or did I miss something?

Hi Justin

I just googled for *conditional order by* and got an interesting hit
that might help.

In a CASE, the results must be the same data type, I saw. It wasn't IBM
i, but the rule still holds.

One solution was to use multiple CASE, something like this - I'm just
taking a wild shot here - each CASE can have its own data type -

order by
(case :H <> :H then NumericCol end)
(case :H = :H then CharCol end)

Your USING clause would add a couple values.

Here's a link to the page -
