Unlike many database systems out there, the overhead for BLOB/TEXT fields in MySQL (I normally just use TEXT) is practically none. Other databases (Sybase, IME) allocate at minimum a 2kb page for each TEXT field in a table, even if the TEXT field is empty. Eeek!

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
