SSIS DATA FLOW TASK - USING FIELD IN EXISTING TABLE

I have a package set up that successfully imports a csv file into a table in MS SQL 2008 database.  It imports data into all columns in that table except for 1.  In that last column, I wish to fill it in with whatever date rests in a field in another table.  The other table has only 1 record, so I thought somewhere I could say "select fieldname from tablename" and use the result for that last column.

Not sure what the best way to do this would be.

Isn't there a way to build a variable that selects whatever value I have in the other table and use it in the column mapping in my data flow?

Sure, map first the result set to your variable:

Then with 'Derived Column' you can add your variable as a new column inside the data flow.

I seem to be on the right track using liija's link above, but am getting an error in the Execute SQL Task:

An error occurred while assigning a value to variable "xyz".  The type of the value being assigned to variable "xyz" differes from the current variable type.  

The value I am trying to put in the variable is of "date" datatype.  The variable only lets me choose datetime.  

How do I fix?

Thanks

You could cast your date column to datetime inside your SQL - since there is no 'Date' data type in SSIS.

SELECT CAST(YourDateColumn AS DATETIME) AS YourDateColumn FROM YourTable

Thanks, but I seem to be getting a different error now.  It is still occurring in the Execute SQL Task:

"Unable to find 'mydatecolumn' in the result set".

Sorry, the above actually worked.  I neglected to put the " AS yourdatecolumn" at the end.

THANK YOU!
