请编写T-SQL语句实现如下功能
--check database whether exist, if true，drop database -- if exists (select * from sysdatabases where name = 'Student') Drop database Student else Create database Student
--create table-- Use Student Create table Member( MID char(10) primary key, MName char(50) not null )
Create table F( FID char(10) primary key, FName char(50) not null )
