Union All is not bring the second part columns to the report

Question

I have 5 groups of series of Select statements and then I made a UNION ALL after the first group. Now it does run correctly and displays the output but it does not assign the second group' s field names.
For example. I am greatly abridging
Completed the SQL's needed to mimic a IBM i display screen. There are 5 product groups making up the screen. I was hoping to have one large Command SQL having the 5 SQLs using UNION ALL. This does 'compile' as a Command. However, it does only brings in the first part fields not the second. So this field is not included in the list of fields tree for COMMAND. PROGR2R2PST,
Is there something not correct how doing the UNION ALL? OUTPUT assigns the column name
of the first group to the second group. HLDGR1PUN 21454 87273
so if i wanted to have one large SQL with union ALLs, it wont work. is there something other than UNION ALL I should use? One idea is if I can have 5 commands to my disposal. I guess  using subreports you can but it will be too slow.
SELECT
count(*) as PROGR1PST,
SELECT COALESCE(SUM(OdQty#),0)

Answer 1

hi Paul,
a union combines record sets like this
field1     field2
1          2
union
field3     field4
2          8
will produce
field1     field2
1          2
2          8
note that there are no more field3 & field4 names. that's the way a union works.
if you need separate fields for your other values then you would need to use sub-queries instead. to do that delete "UNION ALL " and create sub-queries with anything that is beneath that statement.
