MySQL Gotchas | Gotcha: "user" is not a reserved word

In MySQL, user is not a reserved word and can be used as-is as a table name. As web applications in particular often have their own user table, it is in common use, which is perfectly understandable.

However, according to the various ANSI SQL standards, user is a reserved word (see e.g. here or here), and this leads to problems when converting MySQL schema definitions to other databases, such as that described here.

Note that as of MySQL 5.0.19, even when selecting MySQL's ANSI Mode, "user" does not appear to treated as a reserved word, and no warnings are given when it is used to create a table.
