Hi experts,

I am new to SSIS 2008 and I wanted to add a new derived column to my table.  What I really want is a way to write a SQL expression to do the same thing as this TSQL statement:

, ISNULL(DateTime1, Datetime2) AS Arrived

how do I do the same thing as above as an SQL expression and have it create a new Column for me called Arrived?

Well, I think it will work.  I have an ole db source, on success connected to a derived column.  The column exists in the Source (As I added it as a datetime column).  There are only around 200,000 rows from the source but It is reading 4X that.  Any ideas what I might have done wrong?  I can submit as a separate question if that would be better.

do I need to run the Derived column through a data conversion step first?
