Chris, it should be noted that a BLOB is binary data, not character data like VARCHAR. BLOBs will act differently in terms of case-sensitivity for example. The TEXT data type might be more what you're looking for.

See http://dev.mysql.com/doc/refman/5.0/en/blob.html for some more info on BLOB and TEXT.

Hard to say what difference in performance would be like. If database isn't used much, does it matter much?

Hello,

Originally I had this long explanation of what I'm doing and why I'm asking this question but I thought I'd just cut to the chase and ask...

For a db that doesn't get a lot queries is there much of a performance difference between BLOB and VARCHAR(255)?
