Different versions of the MySQL
server may return different
metadata. Unlike with some of
the PHP MySQL extensions no
attempt is made to hide MySQL
server version dependencies and
version details from the caller.
Please, refer to the MySQL C
API documentation that belongs
to the MySQL server in use for
further details.
The metadata list contains one
entry for every column.
