Making Matched Records with Primary File in Query an Outer join in SQL

I have a query that works just as I want it to. I used the RTVQMQRY command to retrieve the source and then I modified the source using interactive SQL to try to "mimic" the Query in SQL. I am *close* but not quite there.

I used "Matched Records with Primary File" in the query because I want the missing records to show up as blanks in the query output. The query produces the desired results. When I run the SQL, I get the same records, sans the "missing" ones. It is a complex query joining 5 files, some of which have 5 key fields to join. What I can't figure out is what the join syntax is in the query. It must be using an outer join but are all the 5 files using left outer join syntax? e.g

select (fields)
from
file 1
left outer join file2 on
(file1 and file2 field selections)
left outer join file3 on
(file1 and file3 field selections)'
left outer join file 4 on
(file 1 and file4 field selections)
where (field selections)
order by (whatever)

Any way to see what Query/400 is using?

Thanks,
