If you really want to give the driver a hint about what datatype you are passing, you can change the 'undef' in my "do" statement to { TYPE => SQL_BLOB } and it will have the same effect.

I could have been more verbose on the example, but the original poster did ask for the fastest way. :)

Update: Now that I look at it, he just said the best way, not the fastest. Heh. Oh well.
