本次要讲的连接查询有内连接,外连接,自连接

由于全连接性能太差,使用率太低,就略过它

 

内连接

  隐式内连接

--隐式内连接  查询招生部门所有男老师信息  
select tname,dname from teacher t,dept d
where t.deptno=d.deptno and d.dname=招生部
and t.gendar=

 

  显式内连接

--显式内连接  查询招生部门所有男老师信息   
select tname,dname from teacher t inner join dept d
on t.deptno=d.deptno and d.dname=招生部
and t.gendar=

 

外连接

  左外连接,意思是已左面的表为准,他所有的记录都要查出右面那张表中所对应的记录

--左外连接
select * from teacher t left join dept d
on t.deptno=d.deptno

 

  右外连接意思是已右面的表为准,他所有的记录都要查出左面那张表中所对应的记录

--右外连接
select * from teacher t right join dept d
on t.deptno=d.deptno

 

自连接

--查询teacher表中老师的导师
select t1.tname as "姓名",t2.tname as "导师姓名"
from teacher t1,teacher t2
where t1.mgrno=t2.tno
