They are variable length. I believe they are assigned by blocks (disk chucks, I believe), but I could be wrong on that part. But in your case, you are safe using TEXT/BLOB. If you only store 1 byte, it's only taking 1 byte (plus a couple bytes overhead for the text field). This is all covered somewhere on the MySQL site. Do a google search on "mysql data type size" and you should find some additional information. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
