Syntax Error with Data Import and Upload - Date Field

My data import is set-up so that it picks up files daily from an SFTP.

My Data Warehouse Manager uses SQL to generate a daily TXT file to publish on my SFTP.

Ever since I asked him to add a date field to the daily file, I've been experiencing errors with my automated data import.

I tried just manually uploading the TXT file to Eloqua and get a syntax error message.

I suspect the way he's formatting the date field is causing the problem.

Does anyone have any recommendations on how he should query/format the date field to make it compatible with Eloqua 10?

Thanks!

P.S. I'm not a SQL expert so sorry if I'm not using correct terms, but hopefully you understand what I mean.
