Hi
Incorrect syntax near the keyword 'Select'. & Must declare the scalar variable "@Opening".
Declare @fr_Date as Date Set @fr_Date = '2011/11/11' declare @to_Date as Date Set @to_date = '2021/10/10' Declare @Opening as double Select @Opening = (SUM(Credit)-SUM(Debit)) from JDT1 where RefDate < '2010/11/11' Union all Select (SUM(JDT1.Credit)-SUM(JDT1.Debit)) from OJDT inner join JDT1 on OJDT.transid = JDT1.transid AND JDT1.RefDate >= '2010/11/11' AND JDT1.RefDate < @fr_date
Thanks
