[drupal-devel] Critical error in use of timestamp!

17 Mar 2005

      I just spent two days trying to find out why database backups are not
running. It would seem that naming database columns with a reserved word
is the problem. Timestamp is used as a column name in about 15 instances.

Phpmyadmin and mySQL adminstrator both take the reserved word literally
and execute errors when trying to name a column with time when running
the script.

This is a basic database knowledge thing. Never should programming
language, database or columntypes reserved words be used as column names.

This use is present in 4.5.2 and 4.6
