SQL 2008 VS 2012 Error: Incorrect syntax near the keyword 'COMPUTE' - sql

Question

My friend sent me the commands that he wrote in server 2008 and they worked with no problems, mine however from a copy and past did not work with 2012. Is there any reason why? Here is the code:
Use Kudler_Database
SELECT AccountNumber, [Description], ShortDescription,Balance
FROM Chart_of_Accounts
ORDER BY left (AccountNumber, 2)
COMPUTE SUM(Balance) BY left (AccountNumber, 2)
COMPUTE SUM(Balance);
Here is the error :
Msg 156, Level 15, State 1, Line 6 Incorrect syntax near the keyword
'COMPUTE'.

Answer 1

COMPUTE is no longer available in SQL server 2012, thats why you are getting that error. See this page:
Discontinued Database Engine Functionality in SQL Server 2012
It said that:
This topic describes the Database Engine features that are no longer
available in SQL Server 2012:
*Transact-SQL syntax | COMPUTE / COMPUTE BY *

Answer 2

A kind of hack with RollUp since Compute By is deprecated in SQL Server 2012 - (see "SQL SERVER – Use ROLL UP Clause instead of COMPUTE BY")
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
Result
AccountNumber Balance total
1234567890 2000 2000
1234567890 4000 4000
1234567890 NULL 6000
2345678901 3000 3000
2345678901 NULL 3000
NULL NULL 9000
OR
you can use the below
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
The output being
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

You can create something similar with GROUPING SETS but it all comes in one resultset, eg something like:
SELECT AcGroup, AccountNumber, [Description], ShortDescription, SUM( Balance ) Balance, GROUPING_ID(AcGroup, AccountNumber)
FROM ( SELECT LEFT( AccountNumber, 2 ) AcGroup, * FROM Chart_of_Accounts ) x
GROUP BY GROUPING SETS( (AcGroup), ( AccountNumber, [Description], ShortDescription ), () )
SELECT AcGroup, SUM( Balance ) Balance
FROM ( SELECT LEFT( AccountNumber, 2 ) AcGroup, * FROM Chart_of_Accounts ) x
GROUP BY GROUPING SETS( AcGroup, () )
SELECT AcGroup, SUM( Balance ) Balance
FROM ( SELECT LEFT( AccountNumber, 2 ) AcGroup, * FROM Chart_of_Accounts ) x
GROUP BY AcGroup WITH CUBE
I've added GROUPING_ID() which makes it easier to work out if the source is an original, summary to total row.
I always wondered how you would consume something like that as the multiple resultsets make it difficult to handle. You can't pass it to another stored procedure, you can't copy it paste it directly to Excel (without messing around), passing to a .net client would be awkward. How did you consume the previous code?
