I am creating logs via Perfmon on things like Page File Byte Peak, etc. and I'm having a bit of trouble with getting them to import into a table with a datetime data type because the .csv file is being seen as a text field and throws an error. Is there something I can do in SSIS to convert the data before inserting into the table? I'm a little new to SSIS...but currently I have a package setup that works if I just import into a new table (as text) so there has to be something I can edit to convert it first.

Yes there is. You can fire the date into a derived column transformation where you can add a new column which 'derives' a proper date from your date text.

What format is the date text in?

The date is currently in 04/28/2010 12:34:13.868 format.

Here's your Derived Column formula:

SUBSTRING([Column 1],7,4) + "-" + SUBSTRING([Column 1],1,2) + "-" + SUBSTRING([Column 1],4,2) + SUBSTRING([Column 1],11,13)

This will create a new column with data type Unicode String. You can map this column directly to a datetime field in SQL Server, which will look after the conversion implicitly because it's in the universal date format.

Thank you for sending this. I am pretty new to SSIS, could you tell me what type of Control Flow Item I need to put this into or where this needs to go in order to use it properly? Right now I have a Flat File Source and a OLE DB Destination with a Data Flow Path between.

🙂 no problem. Put this between your source and destination, as part of the dataflow.

Hmm...my Data Flow Path Editor only shows General, Metadata, Data Viewers. I don't see anywhere that would allow me to transform the data.

When you double-click on a dataflow transformation, a new window opens. In this window, you will see boxes representing your source and target.

Drag a Derived Column transformation on to this window.

Then delete the line between the source and target.

Then connect source to derived column and derived column to target (use the green 'success' lines).

Then you can double-click on the derived column to set it up.

Then you can open up the destination to modify the mappings ...

Thank you! It worked like a charm (of course) and I've learned something in the process! 😀
