Great question.

My guess is that SQL uses intermediate results, translating the fields in question as needed. DDS files need to match - is there a keyword for CCSID at field level - I forget.

Of course, a multi-format logical is not the same as JOIN in SQL - the logical is more like an SQL UNION. My assumption fits the UNION scenario better.

We encountered the following problem:

We try to create a logical file with multi-format (I know, it is not the
best way). The first physical file referenced by the logical one, has a
CCSID of 500, and the second one has a CCSID of 297. So the creation abort
with a CPF or CPD error. That's normal. To be able to create the
multi-format, we have to accord both physical file CCSID first. That's what
we do now.

My question is the following:
SQL join request is able to work on two different CCSID physical file, if
the join fields are identical. Why is it not possible with DDS multi format?
