Beginning with Release 6.1 it is possible to include ORDER BYs into the
Sub-Selects. But IMHO it does not guarantee that final result is returned in
In this way you may add additional sort columns into the sub-selects and add
a final Order by based on this sort keys.
Select a.*, 1 SortFile, Row_Number() Over(Order By Key1, Key2, ... KeyN)
From YourTable1 a
Select b.*, 2 , RRN(b),
From YourTable2 b
Select c.*, 3, RRN(C)
From YourTable3 c
Order By SortFile, SortKey

Betreff: SQL UNION and ORDER BY
I would like to have a
SELECT with an ORDER BY
And UNION this to another SELECT without an order by.
Is this possible?
It seems that SQL requires the ORDER BY to sort the entire result file.
ORDER BY field1, field2
More field names
