    What version of SQL Server/SSIS are you running? – MguerraTorres Jan 28 at 14:11
  • 2010 version please team – pete Jan 28 at 14:32

    Are those in your SQL query or in you Derived column? It looks like you're using the SQL syntax and not what SSIS uses. Also 2010 isn't a valid version of SQL Server. That may be the visual studio client you're using. – Zane Jan 28 at 14:38

Based on your comment about going back 3 months, I decided to take a different approach.

Create the following SSIS Variables below (I will describe the expression to be assigned to each)

enter image description here

DateIncrementDecrement will contain the number of months to add or subtract from the current date (3 for plus 3 months and negative 3 (-3) for minus 3 months). Altering the value of this variable with successive runs should give you the correct results.

AdjustedDate expression is

DATEADD("MONTH", @[User::DateIncrementDecrement], getdate())

FirstOfMonth expression is

(DT_WSTR,10)(DT_DBDATE)(DATEADD("DAY",-(DAY(@[AdjustedDate])) + 1,@[AdjustedDate]))

MonthName expression is

(DT_WSTR,15)(MONTH(@[User::AdjustedDate]) == 1 ? "January" : MONTH(@[User::AdjustedDate]) == 2 ? "February" : MONTH(@[User::AdjustedDate]) == 3 ? "March" : MONTH(@[User::AdjustedDate]) == 4 ? "April" : MONTH(@[User::AdjustedDate]) == 5 ? "May" : MONTH(@[User::AdjustedDate]) == 6 ? "June" : MONTH(@[User::AdjustedDate]) == 7 ? "July" : MONTH(@[User::AdjustedDate]) == 8 ? "August" : MONTH(@[User::AdjustedDate]) == 9 ? "September" : MONTH(@[User::AdjustedDate]) == 10 ? "October" : MONTH(@[User::AdjustedDate]) == 11 ? "November" : MONTH(@[User::AdjustedDate]) == 12 ? "December" : "")

In your Derived Column Transformation Editor, create two new derived columns

enter image description here

MonthName expression is


FirstOfMonth expression is


  • hi, this is great thank you. What happens if I need to please go back 3 months? got to be honest , hence why I was using the DATEADD(mm part. e.g so date is 01/10/2018, and month is October – pete Jan 28 at 16:03
