Hi guys,
It is a situation where i have to produce some new rows with projected RETAIL_SALES_AMT based on the last quarter's
RETAIL_SALES_AMOUNT and next quarte'rs WHOLESALE_AMT. As you can see from the sample data for a specific customer,
product i have retail_sales_amt populated only upto 04/01/2006 but WHOLE_SALE amt for the same product and customer
are there upto 04/01/2007.
I have to produce a PROJECTED RETAIL_SALES_AMT and it should be inserted as a new row with a flag to identify
a projected row. Here in this case i have to produce a new row for 07/01/2006,10/01/2006 & 01/01/2007 projecting
the RETAIL_SALES_AMT. The formulae for calculation is as under:
projected retail_sales_amt for 07/01/2006=.345+( (07/01/2006 whole_sales - 04/01/2006 whole_sales)/(04/01/2006 whole_sale)))
*04/01/2006 RETAIL_SALES_AMT and going forward for subsequent quarters.
Is there any way i can use a query to produce these new rows by calculating the RETAIL_SALES_AMT on the fly or any
procedural way to do it.
Please help as it looks a bit complicated logic.
Regards

I'm not sure if this is exactly what you want but this shows you the possibilities:
WITH sales_table AS
        SELECT TO_DATE('01/01/2006','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, 454234 AS RETAIL_SALES_AMT, 65633456 AS WHOLESALE_AMT FROM DUAL UNION ALL
        SELECT TO_DATE('04/01/2006','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, 324562 AS RETAIL_SALES_AMT, 45333234 AS WHOLESALE_AMT FROM DUAL UNION ALL
        SELECT TO_DATE('07/01/2006','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, NULL AS RETAIL_SALES_AMT, 67845423 AS WHOLESALE_AMT FROM DUAL UNION ALL
        SELECT TO_DATE('10/01/2006','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, NULL AS RETAIL_SALES_AMT, 67453453 AS WHOLESALE_AMT FROM DUAL UNION ALL
        SELECT TO_DATE('01/01/2007','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, NULL AS RETAIL_SALES_AMT, 56754633 AS WHOLESALE_AMT FROM DUAL UNION ALL
        SELECT TO_DATE('04/01/2007','MM/DD/YYYY') AS QUARTER, 'ABC' AS CUSTOMER, 'VACUUM CLEANER' AS PRODUCT, NULL AS RETAIL_SALES_AMT, 45423434 AS WHOLESALE_AMT FROM DUAL
