Need a Standalone Visual Query Tool for multiple database types (ODBC), Any Suggestions?

Hello All,

I need to find a standalone program that offers a Visual Query Editor interface for designing select statements, that can execute SQL Statements against multiple types of Databases (through ODBC), and can export the results to a CSV file (or some other flat text format).

I have tried searching around on the net for a couple of days, and I have yet to find anything that meets these requirements.  I've been trying to limit my search to freeware programs, but if I have to pay a small fee for a program I do not mind.

I need to be able to run this program off of a flash drive (thumb drive, jump drive, whatever you want to call it).  I am in and out of clients offices all day and you would be surprised how many of them lack any program that can connect to a database through ODBC.  I mean, I thought that Excel was pretty much standard in any office setting, but I digress...

If anyone can make some recommendations on software that I should try, I'd really appreciate it.

Thanks.
