Question

SELECT   TRACK_NUM, MIN(sub_account) AS START_KEY, MAX(sub_account) AS END_KEY

              SELECT to_number(sub_account) as sub_account,
              RANK() OVER (PARTITION BY sub_account

              FROM  STG_SUB_MASTER_MONTH_HISTORY)
              WHERE ROW_INSTANCE = 1

Hi, Vakeel,
The usual way of using the results of one query in another is to join the two queries. Sometimes it's easier to do a corellated sub-query instead. I can't tell which is the best way for you, or exactly how to do it, because I don't understand exactly what results you want.
Please post a few rows of sample data and the results you want to get from that data. Simplify as much as possible. For example, post a query that uses NTILE (4) instead if NTILE (20). (If you know how to solve one, you can solve the other.)
Another example: only select a couple of columns in the second query.
