以下是查询:
装备栏:

ALTER TABLE your_table MODIFY COLUMN equip int(11) unsigned NOT NULL default '0'

移动位置更改:

ALTER TABLE your_table CHANGE slotchange moves int(11) unsigned NOT NULL DEFAULT '0'

char_opt 至 unban_time:

ALTER TABLE your_table CHANGE char_opt unban_time int(11) unsigned NOT NULL default '0'

输入列:

ALTER TABLE your_table MODIFY COLUMN type enum('M','P','L','T','V','S','N','C','A','R','G','E','B','O','I','X','D','U','$') NOT NULL default 'P'

MODIFY 用于更改列的数据类型和其他属性，CHANGE 用于更改表列的名称和其他属性。
哦，并一一运行查询:D
