将SQL Server Query 2012转换为2008

Question

The Third Output is All I want I query that using sql server 2012 using this query

Select LACCT,LREFNO,CONVERT(char(10), LDATE, 101) AS DATE,Description,Debit,Credit,Balance
From 
    (
        SELECT 
        LACCT, 
        LREFNO, 
        LDATE, 
        Description,
        Debit,
        Credit, 
        SUM(Debit - Credit) OVER (ORDER BY LDATE  ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW) AS Balance
    FROM
        (
            Select  
                a.LACCT,
                a.LREFNO,
                a.LDATE,
                b.Description ,
                case when a.LDBCR = 'D' then cast(a.LAMOUNT AS decimal(20,2)) else '0.0' end Debit,
                case when a.LDBCR = 'C' then cast(a.LAMOUNT AS decimal(20,2)) else '0.0' end Credit

            FROM [dbo].[BCS02001] AS a
                 JOIN [dbo].[ref_LedgerParticulars] as b ON a.LCODE = b.Code  
                 where a.LACCT= @AcntNo 
          ) LedgerTable ) tblAll where year(LDATE) = @YEAR

But this Query is not Running on SQL SERVER 2008 r2

OVER (ORDER BY LDATE  ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW)

How can I convert this to sql; server 2008 r2

thank you

Answer 1

Remove this from the code:

 ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW

It is something v2008 doesn't support. However, removing it will not change anything, as this line is the default window.
