insert into Student(Sno,Sname,Ssex,Sage,Sdept) values'95001','李勇','男','24','CS' '9500'1错误
insert into Student(Sno,Sname,Ssex,Sage,Sdept)

insert into Student(Sno,Sname,Ssex,Sage,Sdept) values'95001' 实验中的SQL部分学生表:Student(Sno,Sname,Ssex,Sage,Sdept) 课程范式的判断st(sno,sname,ssex,sage,sdept)c(cno,cname,cdept,tname)sc 2、给出如下关系模式：Student(sno,sname,sex,sage,sdept,add（家庭住址）) Cours select Student.Sno,Sname,Ssex,Cname,Grade from Student,SC,Co SQL中表 Student(S#,Sname,Sage,Ssex) Course(C#,Cname,T#) 中的 S# String sql="update student set sname='"+name+"',ssex='"+sex+ select sname,avg(grade) from sc,student wherestudent.sno=sc. String sql="insert into tb_IPcount values("+this.times+",'"+ insert into 具体是：insert into db_friend(Uid,Fid)values('3','Resource id') 有数据库学生s(sno ,sname ,age ,sex) 成绩 sc(sno ,cno,grade) 课程 c(cn
