I will create some pseudo code to explain my problem:
WITH MAX_BES AS
(SELECT MAX(ID) AS MAX_ID FROM TABLE1);
SELECT .....
FROM
TABLE2, TABLE3
WHERE
TABLE2.ID IN (MAX_BES.MAX_ID);
The code above does not work. How should I reference a column from my WITH clause within an IN clause?
Thanks a lot for your quick feedback.
Use a sub-select and make that one statement, not two.
WITH max_bes AS (
SELECT max(id) AS max_id
FROM table1
) --<< no ; here!
SELECT .....
FROM table2
JOIN table3 ON ... ??
WHERE table2.id IN (SELECT max_id FROM max_bes);
