Re: SQL multiformat logical

Closest thing I can think of is UNIONs, as you came to. Each SELECT could have some "format ID", a literal that you assign, plus the common fields from each file as separate columns, and finally a concatenation of whatever is left into a long character field. The program reading the file would need a way to break up this long field based on the format ID.
Or maybe just have the format ID and the common fields, then let the program using the result set take action to get the rest of the fields. 

Eh? Whadya think?

Is there some way to do a multiformat logical file in SQL?  Or, instead of
that is there something else I can do to fit that same bill?  Must be SQL
and not DDS.  We're not really talking about any particularly large files.
 Actually a small set of transaction data.  Like a days' worth of EDI
transmissions perhaps.  I am wondering if, instead of the multiformat
logical file I do something like
CREATE TABLE...  AS SELECT ... UNION this and that and the other thing.
Make sense?
