Thanks for the confirmation.

So far my tests corroborate.

No need for CTE's

UNION ALL is all the Richard needs

Select * from table1 join table 2 on date and type=?FI?
UNION ALL
Select * from table1 join table 2 on type=?I?

If you want duplicates between the two sets removed, then just use UNION Select * from table1 join table 2 on date and type=?FI?
UNION
Select * from table1 join table 2 on type=?I?

UNION is a SQL set operator. The others available are INTERSECT and EXCEPT https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_72/db2/rbafzmark.htm

Try this

Or something like that
