Delete Rows From A Table Matching A Calculated Date

Hello I am new to SSIS and learning as I go. Any guidance to my questions would be appreciated.

I wrote a script that takes the current date and subtracts a number of days/months from this date. I then attempted to use an SQL Task as a select with a parameter using the calculated date from the script. I was not successful in doing this. While performing searches on the WEB with the hopes of finding a solution I came upon the following text in the Microsoft forum under EXECUTE SQL TASK.

When you use an OLE DB Connection Manager, you cannot use parameterized subqueries because the Execute SQL task cannot derive parameter information through the OLE DB provider. However, you can use an expression to concatenate the parameter values into the query string and to set the SqlStatementSource property of the task.


Having come upon this statement I moved on to putting together an OLE DB SOURCE with a Flat File Destination. The SQL that I wrote is:

SELECT BP_ID, INVC_NBR, INVC_DT, BUS_ADD_DT
FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)

The flat file destination was mainly used to confirm the select.

Having confirmed my select, I changed the select in the OLE DB SOURCE as follows:

DELETE FROM DW.CUST_SALE_ADDR
WHERE (BUS_ADD_DT = ?)

I also removed the Flat File Destination. Needless to say when I tried to run the package I did not get very far as a package validation error was encountered since there were no output columns.

Can you share how I should go about peforming the delete as described from the table based on a calculated date? And am I not understanding the comment regarding the SQL Statement and the use of parameters?

Thank you and God Bless.
