新手求教！急！！SQL sever 转MYSQL

create table users(userId varchar(10) not null, /*用户账号，主键*/userName varchar(10) not null, /*用户名*/userPassword varchar(10) not null, /*密码*/idNo varchar(20) not null, /*身份证号码,唯一*/userMoney numeric(10,2) default 0, /*总金额，不能小于零*/userStatus varchar(4) check (userStatus='使用' or userStatus='冻结') default '使用', /*用户状态（使用，冻结），默认是使用中*/userAddress varchar(30) not null, /*用户地址*/startTime DateTime, /*开户时间，应该是开户时的系统时间，不应该人为输入*/primary key(userId), /*设置主键*/)--用户的状态一旦变成冻结状态，那么卡也应该不能使用create trigger userstatus_updateon usersafter updateasif update(userStatus)begin if (select userStatus from inserted) = '冻结'update card set cardStatus = '冻结' where userId = (select userId from deleted)if (select userStatus from inserted) = '使用'update card set cardStatus = '使用' where userId = (select userId from deleted) end

CREATE TABLE users (
userId VARCHAR (10) NOT NULL,
userName VARCHAR (10) NOT NULL,
userPassword VARCHAR (10) NOT NULL,
idNo VARCHAR (20) NOT NULL,
userMoney NUMERIC (10, 2) DEFAULT 0,
userStatus VARCHAR (4) ,
userAddress VARCHAR (30) NOT NULL,
startTime DATETIME,
PRIMARY KEY (userId)
);

CREATE TRIGGER userstatus_updateon usersafter updateasif 

UPDATE
(userStatus)
BEGIN
IF
(SELECT
userStatus
FROM
inserted) = '冻结'
UPDATE
card
SET
cardStatus = '冻结'
WHERE userId =
(SELECT
userId
FROM
deleted) IF
(SELECT
userStatus
FROM
inserted) = '使用'
UPDATE

SET

WHERE userId =

END
