Pass a variable value to SQL Command in OLEDB Source

Question

Hi,
  I have the OLEdb Source where it has SQL Command as Data Access Mode. Below is the sample query that i have in that.
DECLARE @MonthOffSet int = 24
DECLARE @PaidDate_SK_Low datetime = dateadd(mm,MONTH(getdate())-@MonthOffSet-1,dateadd(year,datediff(year,0,dateadd(YY,0,getdate())),0))
DECLARE @PaidDate_SK_High datetime = dateadd(dd,-1,dateadd(MM,@MonthOffSet,@PaidDate_SK_Low))
followed by select statement which has where clause.
 Instead of hard code the value 24, i am trying to get the value from variable. I know there is a limitation to add the parameters only in where clause. Is there any work around or solution.

Answer 1

But i need to use the first four lines of code in lot other packages which has different sql statement. But if i make whole query variable then i have a limitation on length 4000 char.
DECLARE @MonthOffSet int = 24
DECLARE @PaidDate_SK_Low
datetime = dateadd(mm,MONTH(getdate())-@MonthOffSet-1,dateadd(year,datediff(year,0,dateadd(YY,0,getdate())),0))
DECLARE @PaidDate_SK_High
datetime = dateadd(dd,-1,dateadd(MM,@MonthOffSet,@PaidDate_SK_Low))
in my select statement in where clause i am using date range between @PaidDate_SK_Low
datetime  and @PaidDate_SK_High
datetime 
Any suggestions
