Following query Provides summary of accounts receivable by ship to state for a particular date range. Used by Financial, Operations, etc. departments to track outstanding accounts receivable balances.
I Need to add some columns like
Outstanding Balance column logic:INVOICE_FACT_OES.ACCOUNT_RECEIVABLE_FACT.AMOUNT_TOTAL_REMAINING
Current: AMOUNT_TOTAL_REMAINING – summed up for today’s date through 30 days back
31-60 DaysAMOUNT_TOTAL_REMAINING – summed up for the 31-60 day time period
61-90 DaysAMOUNT_TOTAL_REMAINING – summed up for the 61-90 day time period
91-120 DaysAMOUNT_TOTAL_REMAINING – summed up for the 91-120 day time period
121-150 DaysAMOUNT_TOTAL_REMAINING – summed up for the 121-150 day time period
151-180 DaysAMOUNT_TOTAL_REMAINING – summed up for the 151-180 day time period
181-99999 DaysAMOUNT_TOTAL_REMAINING – summed up for the 181 day and beyond time period
Query I wrote :
SELECT
CS.STATE_ABBREV as State,
CA.ACCOUNT_NUMBER as Account#,
CA.CUSTOMER_ACCOUNT_NAME OrgName,
CS.CUST_SITE_USE_NAME CustName,
CS.EMAIL_ADDRESS ContactEmail,
CS.PHONE_NUMBER ContactPhone,
AR.APPLY_DATE,
AR.STATUS,
AR.AMOUNT_TOTAL_REMAINING "Outstanding Balance",
(select SUM(AMOUNT_TOTAL_REMAINING) from ACCOUNTS_RECEIVABLE_FACT
where
APPLY_DATE between GETDATE()-30 and GETDATE()
group by APPLY_DATE)as "Current",
(select SUM(AMOUNT_TOTAL_REMAINING) from ACCOUNTS_RECEIVABLE_FACT
where
APPLY_DATE between GETDATE()-60 and GETDATE()-30
group by APPLY_DATE)as "31-60 Days",
(select SUM(AMOUNT_TOTAL_REMAINING) from ACCOUNTS_RECEIVABLE_FACT
where
APPLY_DATE between GETDATE()-90 and GETDATE()-60
group by APPLY_DATE)as "61-90 Days",
(select SUM(AMOUNT_TOTAL_REMAINING) from ACCOUNTS_RECEIVABLE_FACT
where
APPLY_DATE between GETDATE()-120 and GETDATE()-90

(select SUM(AMOUNT_TOTAL_REMAINING) from ACCOUNTS_RECEIVABLE_FACT
where
APPLY_DATE between GETDATE()-180 and GETDATE()-150
group by APPLY_DATE)as "180-150 Days"

My guess is that writing your query to use correlated subqueries in that fashion is going to be obnoxiously slow.

You might consider restructuring that query to be something like this:

SELECT

CS.STATE_ABBREV as State,

CA.ACCOUNT_NUMBER as Account#,

CA.CUSTOMER_ACCOUNT_NAME OrgName,

CS.CUST_SITE_USE_NAME CustName,

CS.EMAIL_ADDRESS ContactEmail,

CS.PHONE_NUMBER ContactPhone,

AR.APPLY_DATE,

AR.STATUS,

AR.AMOUNT_TOTAL_REMAINING [Outstanding Balance],

ARP.[Current],

ARP.[31-60 Days],

ARP.[61-90 Days],

ARP.[91-120 Days],

ARP.[121-150 Days],

ARP.[151-180 Days]

FROM CUSTOMER_SITE_USE_DIMENSION CS

INNER JOIN CUSTOMER_ACCOUNT_DIMENSION CA ON CS.CUSTOMER_ACCOUNT_ID = CA.CUSTOMER_ACCOUNT_ID

INNER JOIN TIME_DIMENSION TD ON AR.APPLY_DATE = TD.STANDARD_DATE

AND AR.INCLUDE_IN_BALANCE_IND in ('Y')

AND AR.TRANSACTION_TYPE IN ('CM','INV')

INNER JOIN (

SELECT CS.CUSTOMER_SITE_USE_ID,

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-30 AND GETDATE() THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [Current],

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-60 AND GETDATE()-30 THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [31-60 Days],

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-90 AND GETDATE()-60 THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [61-90 Days],

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-120 AND GETDATE()-90 THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [91-120 Days],

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-150 AND GETDATE()-120 THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [121-150 Days],

SUM(CASE WHEN APPLY_DATE BETWEEN GETDATE()-180 AND GETDATE()-150 THEN AMOUNT_TOTAL_REMAINING ELSE 0 END) [151-180 Days]

FROM CUSTOMER_SITE_USE_DIMENSION CS

INNER JOIN ACCOUNTS_RECEIVABLE_FACT ON CS.CUSTOMER_SITE_USE_ID = AR.CUSTOMER_SITE_USE_ID

INNER JOIN TIME_DIMENSION TD ON AR.APPLY_DATE = TD.STANDARD_DATE

AND AR.INCLUDE_IN_BALANCE_IND in ('Y')

AND AR.TRANSACTION_TYPE IN ('CM','INV')

GROUP BY CS.CUSTOMER_SITE_USE_ID

) ARP

ON CS.CUSTOMER_SITE_USE_ID = ARP.CUSTOMER_SITE_USE_ID

This being 2005, you can do much the same thing with a CTE and possibly increase the readability of that some.

Consistency is only a virtue if you're not a screwup. 😉

Seth is spot on... here's an article that explains the performance advantage of the method he used...

http://www.sqlservercentral.com/articles/T-SQL/63681/

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
