Then is IBM's manual incorrect? (GASP!!)

According to the V7R1 version of the IBM i:DB2 for I SQL Reference, at pages 974-975, it states:

"The ORDER BY and FETCH FIRST clauses may not be specified except within
a common-table-expression."

It does not state that the ORDER BY will not be honored. My expectation was that the CTE would be constructed in the proper sequence and the subsequent select over the CTE would return the data in the proper sequence.

You've done nothing wrong ORDER BY simply isn't allowed/honored in a view.
Your ORDER BY will have to be in your code.


Thanks,

Hey all.

I trying to create an SQL View that will use a CTE in order to use the ORDER BY clause (as suggested by the IBM i: DB2 for i SQL Reference manual on page 974-975). I am on V7R1.

CREATE VIEW needles.VIEW (Fld1 , Fld2, Fld3, Fld4) AS with interim as (SELECT Fld1, Fld2, Fld3, Fld4 FROM needles.TABLE WHERE Fld4 = 'Y'
ORDER BY Fld3, Fld2)
select * from interim

This will create the view, but the ORDER BY doesn't seem to take. Using DBU to look at needles.VIEW, I find that the rows are not in Fld3, Fld2 order.

What have I done wrong?
