Compute By が SQL Server 2012 で廃止されたため、RollUp を使用した一種のハック- (「SQL SERVER – COMPUTE BY の代わりに ROLL UP 句を使用する」を参照)
DECLARE @t TABLE(AccountNumber VARCHAR(10),[Description] VARCHAR(100),ShortDescription VARCHAR(100),Balance INT)
INSERT INTO @t SELECT '1234567890','Some Description for 1st Account','Short Description for 1st Account',2000 Union All
SELECT '2345678901','Some Description for 2nd Account','Short Description for 2nd Account',3000 Union All
SELECT '1234567890','Some Description for 1st Account','Short Description for 1st Account',4000
SELECT
AccountNumber
,Balance
,Total = SUM(Balance)
FROM @t
GROUP BY AccountNumber,Balance
WITH ROLLUP
結果
AccountNumber Balance total
1234567890 2000 2000
1234567890 4000 4000
1234567890 NULL 6000
2345678901 3000 3000
2345678901 NULL 3000
NULL NULL 9000
また
以下を使用できます
DECLARE @t TABLE(AccountNumber VARCHAR(10),[Description] VARCHAR(100),ShortDescription VARCHAR(100),Balance INT)
INSERT INTO @t SELECT '1234567890','Some Description for 1st Account','Short Description for 1st Account',2000 Union All
SELECT '2345678901','Some Description for 2nd Account','Short Description for 2nd Account',3000 Union All
SELECT '1234567890','Some Description for 1st Account','Short Description for 1st Account',4000
;With CTE AS
(
SELECT
AccountNumber
,[Description]
,ShortDescription
,Balance
,SubTotal = SUM(Balance) OVER (PARTITION BY AccountNumber ORDER BY LEFT (AccountNumber, 2))
,Rn = ROW_NUMBER() OVER(PARTITION BY AccountNumber ORDER BY LEFT (AccountNumber, 2))
FROM @t)
SELECT
AccountNumber
,[Description]
,ShortDescription
,Balance = CAST(Balance AS VARCHAR(10))
,SubTotal = CASE WHEN Rn != 1 THEN NULL ELSE SubTotal END
FROM CTE
UNION ALL
SELECT
' ', ' ',' ' ,'Total Amount' , SUM(Balance) FROM CTE
出力は
AccountNumber Description ShortDescription Balance SubTotal
1234567890 Some Description for 1st Account Short Description for 1st Account 2000 6000
1234567890 Some Description for 1st Account Short Description for 1st Account 4000 NULL
2345678901 Some Description for 2nd Account Short Description for 2nd Account 3000 3000
Total Amount 9000
