OVRDBF and SQL

I'm writing an SQLRPG program to insert data into one of three identical
files, depending on which brand the data is from.
 
When searching the archives, I see that OVRDBF has been suggested as an
option for dealing with multi-member files, and thought it might work in
my situation as well. 
 
I generally like to use QCmdExc to do my OvrDBF's when dealing with RPG,
then open the file.  But in SQL, I don't even declare the file on the F
specs, so open/close doesn't seem to apply.  
 
Will this work, or do I have to do my Override in a CL or calling RPG
program.  Or, should I declare the file and open it before I run the SQL
? 
 
Here's what I've got.  It works when the override is not necessary, but
when I pass in one of the "alternate" files, I get no data in any of
them.
