select * from student

多行查询

--定义存储过程，返回游标
create or replace procedure  getallstudent(resule out sys_refcursor) is  --返回游标
begin 
	open resule for select * from student;
end;

--查询存储过程
declare
	cur sys_refcursor;  --游标
	result_row student%rowtype;  
begin
	getallstudent(cur);
	loop
		fetch cur into result_row ;
		exit when cur%notfound;
		dbms_output.put_line('id: '||result_row.id||' tid: '||result_row.tid||'sid: '||result_row.sid||' sname: '||result_row.sname||' age: '||result_row.age||' sex: '||result_row.sex);
	end loop;
	close cur;
end;

drop  procedure getallstudent 
select * from student

create or replace  procedure  delstudentofteacher(mytid in varchar2)
is 
begin
	delete from student where tid=mytid;
end delstudentofteacher; 

<delete id="teacherdelete" parametertype="int">
        {call delteacher(#{arg0})}
</delete>

<delete id="studentofteacherdelete" >
        {call delstudentofteacher(#{arg0}) }
</delete>

@test
    void contextloads() {
        teacherservice.deleteteacher(2);

<insert id="teacheradd">
        call addteacher(#{arg0},#{arg1},#{arg2})
</insert>

改

create or replace  procedure  updateteacher(mytname in varchar2,myage in varchar2,mytid in varchar2)
is 
begin
	update   teacher set tname=mytname,age=myage where tid=mytid;
end updateteacher; 

<update id="teacherupdate" >
        call updateteacher(#{arg0},#{arg1},#{arg2});
</update>

学生增删改
