如何用mysql建立图书管理系统（图书管理系统的sqlserver数据库设计示例）

CREATE DATABASE BMS
 
IF OBJECT_ID(N't_booktype',N'U') IS NOT NULL
	DROP TABLE t_booktype
CREATE TABLE t_booktype(
	typeno int primary key not null,
	typename varchar(30) not null

	bookno int primary key not null,
	bookname varchar(30) not null,
	typeno int not null
)
 
IF OBJECT_ID(N't_readertype',N'U') IS NOT NULL
	DROP TABLE t_readertype
CREATE TABLE t_readertype(
	readertypeno int primary key not null,
	readername varchar(30) not null,
	lendnumber int not null

IF OBJECT_ID(N't_readerinfo',N'U') IS NOT NULL
	DROP TABLE t_readerinfo
CREATE TABLE t_readerinfo(

CREATE TABLE t_lendbook(

	returntime datetime
)
