Hi!
I have a derived table in which there is an outer select statement and in FROM clause I have 2 more selects. I need to add a colum to outer select based on table in FROM clause. Now the other queries seemed pretty simple but here is the issue with this one. On DB level the table from which I have to add column to current derived table is in the FROM select clause of this derived table. Am I supposed to add this column if this table from which this column is coming, is in FROM select clause of the derived table? If I do then do I have to add this column to select clause in FROM clause first and then subsequently add to outer select? Thanks.

CONCAT(CONCAT(CONCAT('FY ',Table1."Period1"), ' to FY '), Table2."Period1") AS "YEAR_PERIOD",
ROUND(((Table1."SALES" - Table2."SALES")/Table2."SALES") * 100, 2) AS "PERCENT",
Table1."NEW COLUMN"
FROM
(SELECT "Customer ID", TO_NUMBER(SUBSTR("Period1", 3, 4)) "PERIOD1", SALES, "NEW COLUMN"
FROM BO."Company Sales" A1
WHERE TO_NUMBER(SUBSTR("Period1", 3, 4)) =
(SELECT MAX(TO_NUMBER(SUBSTR("Period1", 3, 4))) MAXPERIOD FROM BO."Customer Sales" WHERE "Period1 End Month" IS NULL GROUP BY "Customer ID" HAVING
"Customer ID" = BO."Customer ID" )
AND (NOT "Period1" = 'P')
AND "Fiscal Period End Month" IS NULL) TABLE 1,
(SELECT "Customer ID", TO_NUMBER(SUBSTR("Period1", 3, 4)) "Period1", SALES, "NEW COLUMN"
FROM BO."Company Sales" A2
WHERE TO_NUMBER(SUBSTR("Period1", 3, 4)) =
(SELECT MAX(TO_NUMBER(SUBSTR("Period1", 3, 4)))-1 PREVPERIOD FROM BO."Company Sales" WHERE "Period1 End Month" IS NULL GROUP BY "Customer ID" HAVING
"Customer ID" = A2."Customer ID" )
AND (NOT "Fiscal Period" = 'FY')
AND "Period1 End Month" IS NULL) Table2
WHERE Table1."Customer ID" = Table2."Customer ID"
AND Table1."NEW COLUMN"='Y'
I have the above derived table where I need to add this column called "NEW COLUMN". But I need to add NEW COLUMN only if the table from which it is coming from is present in the derived table. In this case the table is present in derived table's FROM clause called "Customer Sales". But since it is in another select therefore I am confused. So I have added this NEW COLUMN first in both selects in FROM and then outer select.Also, I need to add this NEW COLUMN as a condition at the end, not sure if I have done that correctly or not. Please let me know if this is the right way to do it since I am concerned about the results.
