MySQL table patcher

Reads a table creation file (tables.sql) and compares it to what mysqldump gives, and creates SQL clauses to update the database to match the creation file.

sqlupdate v1.6.3 - Copyright (C) Joel Yliluoma (http://iki.fi/bisqwit/)

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

Options:
    -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
    -i                    Use CREATE INDEX instead of ALTER..ADD KEY
    -m                    Add comments explaining the differences
    -c                    Ignore character set differences
    -p pass
    -r                    Reverse operation. (new->old)

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).

Since version 1.3.0, supports also the InnoDB FOREIGN KEY constraints.

Since version 1.4.0, supports TINYINT, DATE, TIME and ENUM types.
Thanks to Leigh Purdie for this change!

Since version 1.5.0, supports LONGTEXT, MEDIUMTEXT and MEDIUMBLOB. Also now longer forces DEFAULT for AUTOINCREMENT columns.
Thanks to Frederic Lamsens for this change!
