新破天一剑合区SQL（半成品）

--可以合区,但合区后人物的东西消失了  -_-!!

--存在这里，供以后遇到相关需要时翻查。

--[user]的触发器

CREATE TRIGGER update_chr ON dbo.[user] FOR insert AS
BEGIN        
         update [user] set chr2=chr1+1, chr3=chr1+2 where account = (select account from inserted)
END

--准备工作：

--取消db1库user表chr1字段、chr表cp_no字段的标识列
--取消db3库user表chr1字段、chr表cp_no字段的标识列

--删除db1库user表的触发器update_chr
--删除db3库user表的触发器update_chr

--用以下SQL修复db3的chr_data1-3表，记得改数据库名和表名（先选择要操作的库）

--更新db3中与db1相同的帐号，在后面加一个字母，比如'z'

--将db3的pcikuser所有记录插入到db1中的pcikuser

---pcikuser合并完成
