My question is, is there a way to not hardcode the file name SLSALL? It
doesn't accept a host variable there, like :FileName. I tried setting
it up
with dynamic SQL, parameter markers, and PREPARE, like this:
ActSQL = 'Select Coalesce(Min(INVDT),' + @Q + '0001-01-01' + @Q + ')' +
', Coalesce(Max(INVDT),' + @Q + '0001-01-01' + @@ + ')' +
', Coalesce(Count(*),0) ' +
'Into ?, ? , ? From ?';
Exec SQL Prepare Stmt1 from :ActSQL;
but then couldn't figure out how to execute it. The EXECUTE IMMEDIATE
doesn't like USING. All the examples I found in this regard use a
cursor.

Not to belabor a point, but you can do this with SEQUEL's run time
variables:
SELECT *
FROM &library/&filename
And so on.
I like SEQUEL too, but it's worth noting that this functionality doesn't
trump embedded SQL as you imply. What you suggest is no different than
Jeff using
ActSQL = 'Select Coalesce(Min(INVDT),' + @Q + '0001-01-01' + @Q + ')' +
', Coalesce(Max(INVDT),' + @Q + '0001-01-01' + @@ + ')' +
', Coalesce(Count(*),0) ' +
'Into ?, ? , ? From ' + qualifiedName;
to build his SQL statement, then doing a PREPARE each time he needs to run
it, as others have suggested.
