Question

I have one intresting requirement to achieve. could you please help?
Please find the below tables

**CheckingAccountTable (Assume Table Name – CAT )

AccountNo  TransactionId    BalanceID       Balance1
123           080              103             $30
123           081              103              $20
123           082              103              $10
123           083              62              $0
123           084              63              $0  
123           085              64              $0
123           086              65              $0
123           087              66              $0  
124           090              103             $3
124           091              103             $2
124           092              103             $1
124           093              72              $0
124           094              73              $0  
124           095              74              $0
124           096              75              $0
124           097              76              $0

SavingsAccountTable (Assume Table Name – SAT)

BalanceID    Balance2
103                    $0
62                    $15
63                    $12  
64                    $20
65                    $0
66                    $0
72                    $11
73                    $0  
74                    $0
75                    $0
76                    $0

RESULT SHOULD LOOKS LIKE

AccountNo  Count(TransactionId)  Sum(Balance1+Balance2)
123            6                   107
124            4                   17  

Ok, Here, CAT is the main table and SAT is the sub table to return the balance
I want to find out count of transactionID’s and Sum(Balance1 + Balance 2)

Conditions. If the Balance1 OR Balance 2 is 0, I can’t take transactionID into count

Am not able to acheive it by doing below

SELECT  T.AccountNo,Count(T.TransactionId),
                SUM(T.Balance1 + T.Balance2) 'Stressdays'
        FROM 
                (
                    SELECT  CAT.AccountNo,CAT.Balance1,CAT.BalanceID,CAT,TransactionId  
                            ,CASE   WHEN SAT.BalanceID= 103 THEN
                                        0
                                    ELSE
                                        SAT.Balance2
                                    END AS 'Balance2'
                    FROM    CAT
                            INNER   JOIN  SAT ON CAT.BalanceID = SAT.BalanceID
                            WHERE   CAT.Balance1 <> 0
                            AND     SAT.Balance2 <> 0
                )T
        GROUP BY T.AccountNo

Answer 1

Try the following:

SELECT  CAT.AccountNo, 
        SUM(CASE WHEN CAT.Balance1 <> 0 OR ISNULL(SAT.Balance2,0) <> 0 THEN 1 ELSE 0 END) CountTransactionId,
        SUM(CASE WHEN CAT.Balance1 <> 0 OR ISNULL(SAT.Balance2,0) <> 0 THEN CAT.Balance1+SAT.Balance2 ELSE 0 END) SumBalance1Balance2
FROM CAT
LEFT JOIN SAT
ON CAT.BalanceId = SAT.BalanceId
