This work perfectly like the CTE, well done, but, how to edit sql query only show AccNo <> 1 ??

...

Easy - but first, we need to sort out your dates. You do yourself no favours by changing the date arithmetic back to the original each time I attempt to correct it. This...

where convert(Date,ti.Transaction_Date, 105) BETWEEN convert(Date,'16-09-2012', 105) AND convert(Date,'30-09-2012', 105)

will result in very poor performance, because even if there is an index on Transaction_date, SQL Server will not be able to use it. You need to match the datatype of the date constants to the column, not the other way around. In order to do that, you need to know the data type of Transaction_Date, and if it is a datetime, you need to know if the time component has values. Can you answer this?

because i m passing the value from web is nvarchar, so i need to convert the nvarchar to date format, otherwise, Transaction_Date is DateTime,i just want to compare date, so i need to convert Datetime to Date only, if not some data didn't show in result.

p/s:i just want to compare date, not Date and Time

and Chris,

how we can do at here

OUTER APPLY ( -- SUM of all the amounts prior to date range

SELECT

Top 1 Before_Amount as Open_Balance

FROM Tbl_Transaction ti

WHERE ti.Transaction_AccNo = a.AccNo -- outer ref

AND convert(Date,ti.Transaction_Date, 105) BETWEEN convert(Date,'16-09-2012', 105) AND convert(Date,'30-09-2012', 105)

ORDER BY Transaction_Date

) Option3

if the Open_Balance is null between 16-09-2012 and 30-09-2012,then change the sql query to check the transaction ONLY before 16-09-2012(NOT BETWEEN, IS ONLY BEFORE 16-09-2012) , how to do this??

OUTER APPLY ( -- SUM of all the amounts prior to date range

SELECT

Top 1 Before_Amount as Open_Balance

FROM Tbl_Transaction ti

WHERE ti.Transaction_AccNo = a.AccNo -- outer ref

AND ti.Transaction_Date < convert(Date,'16-09-2012', 105)

ORDER BY Transaction_Date

) Option3
