I'll add the following possibilties to Perrin's list:

5. You're forgetting to call the update() method after you change the value
   via its mutator.

6. You're correctly calling update(), but you're using Oracle or PostgreSQL
   (both of which default to AutoCommit off) or have set AutoCommit to be off
   in some other fashion, and you're forgetting to call dbi_commit().

7. You're correctly calling update() and dbi_commit(), but you overrode the
   db_Main() method and forgot to call __PACKAGE__->_remember_handle('Main')
   so that dbi_commit() will actually work.
