sqlupdate 读取 MySQL 的表定义 SQL 文件，然后与现有数据库中进行比较，然后生成更新数据库结构的 SQL 语句。

Usage:
    sqlupdate [options] >changes.sql
       (Creates an update script)

    -t tablefile          Describes the file containing
                          the new sql layout. Default: tables.sql
    -d database           Default: winnie3
    -h host               Default: localhost
    -u user               Default: root

Example:
  ./sqlupdate -t etimgr.sql -d etimgr | mysql -uroot

This program does not update a database. It only
produces update scripts (which show the differences).
