Using an Alias in a WHERE clause

Closed 9 months ago.
Here is my SQL code.
I used subquery and labeled it, but when I call column from that subquery, it shows that as invalid identifier.
SELECT TSR.Merchant_id, denomination, SUM (no_of_cards)
FROM sales_details
WHERE invoice_id IN (
SELECT invoice_id
FROM sales_header TSR
WHERE entered_by = (
(SELECT account_code
FROM bk_dsr_account_codes
WHERE user_name = 'C'
AND PASSWORD = 'D'
AND mobile_no = '8994035090213391259'))
AND entered_date BETWEEN (TO_DATE ('2013/04/01', 'yyyy/mm/dd')
)
AND (TO_DATE ('2013/06/30', 'yyyy/mm/dd')
))
GROUP BY denomination
error as per below
ORA-00904: "TSR"."MERCHANT_ID": invalid identifier
Please help me to sort out this issue.
I need to call subquery's columns also in my final SQL view.

Answer 1

You can only use colums that are in your FROM clause. So, your query should be something like:
SELECT TSR.Merchant_id, SD.denomination, SUM (SD.no_of_cards)
FROM sales_details SD
JOIN sales_header TSR on SD.invoice_od = TSR.invoice_id
WHERE entered_by = (
(SELECT account_code
FROM bk_dsr_account_codes
WHERE user_name = 'C'
AND PASSWORD = 'D'
AND mobile_no = '8994035090213391259'))
AND entered_date BETWEEN (TO_DATE ('2013/04/01', 'yyyy/mm/dd')
)
AND (TO_DATE ('2013/06/30', 'yyyy/mm/dd')
)
GROUP BY SD.denomination

Answer 2

select * from table1, table2 where table1.userid=x and table2.sdsd=x
also
select * from table1 t1, table2 t2 where t1.userid=x and t2.sdsd=x
same output these 2 above...
try this
SELECT TSR.Merchant_id, denomination, SUM (no_of_cards)
FROM sales_details,TSR
WHERE invoice_id IN (
SELECT invoice_id
FROM sales_header TSR
WHERE entered_by = (
(SELECT account_code
FROM bk_dsr_account_codes
WHERE user_name = 'C'
AND PASSWORD = 'D'
AND mobile_no = '8994035090213391259'))
AND entered_date BETWEEN (TO_DATE ('2013/04/01', 'yyyy/mm/dd')
)
AND (TO_DATE ('2013/06/30', 'yyyy/mm/dd')
))
GROUP BY denomination
