I've made a Flat File Source (test.txt file) using a Flat File Connection. This TXT file contains one string value. I've assigned a COLUMN NAME in the FLAT FILE SOURCE.
Now, how do I get that value in the COLUMN NAME? Do I create a VARIABLE for it and if so, how. What is the next "task" in my data flow to enable me to use that data?
I need to read that text in that Flat File and then INSERT it (with some other data) into a database table.
thanks in advance

Create a Dataflow. In the Dataflow pane, create source and destination components and link them. Create a mapping from source to destination and then you can run the package.

Thanks, Phil. I did that.

I'm getting error

"Error1Validation error. Data Flow Task: SQL Server Destination 1 [1814]: Columns "InputFileName" and "FileName" cannot convert between unicode and non-unicode string data types."

1) I've Googled for solutions to that and everything I see says to put a DATA CONVERSION TRANSFORMATION between the Source & Destination. Is that correct?

2) Also, within the DATA FLOW, where can I write my INSERT statment in order to use the InputFileName from my Flat file, along with some other info, and then INSERT it into my TABLE?

1) Yes

2) Add a Derived Column transformation between your source and destination and assign these items to new columns which can then be used further along your dataflow to INSERT to your destination along with the other data.

sorry, can you point me to a web example of DERIVED COLUMN? I'm looking and playing around with it. IT, along with all the other "tasks" in BIDS have a lot of configurations! It's very confusing to someone whose never used it (like me!)

I'm looking at stuff like this and can not see where I can build a QUERY with a INSERT?

The Derived Column transform is not a place for building queries - it is a place for adding new columns to your dataflow which can then be used later to fire into your destination.

Trial and error and BOL will get you there fairly quickly - for simple dataflows, SSIS isn't that tough, once you get into a certain mindset.
