Part6-向表中插入数据
一、场景如下
插入 insert:
1)向表class1插入数据
id = 1 ,uname = stu1 ,stu1 = 2020
id = 2 ,uname = stu2 ,stu1 = 2020
id=11,uname =stu3,sex=1
id=12,uname = stu4,sex=2
id=13,uname =stu5,sex=1
id=14,uname = stu6,sex=2
2)向表studen1插入数据
id=4,stu_id=11,c_name=stu1,grade=90
id=5,stu_id=12,c_name=lin,grade=100
id=6,stu_id=33,c_name=istester,grade=20
二、实践如下
1)
insert into class1 (id,uname,stu1) values('2','stu2','2020');
insert into class1 (id,uname,sex) values('11','stu3','1');
insert into class1 (id,uname,sex) values('12','stu4','2');
insert into class1 (id,uname,sex) values('13','stu5','1');
insert into class1 (id,uname,sex) values('14','stu6','2');
2)
insert into studen1(id,stu_id,c_name,grade) value('4','11','stu1','90');
insert into studen1(id,stu_id,c_name,grade) value('5','12','lin','100');
insert into studen1(id,stu_id,c_name,grade) value('6','33','istester','20');
用数据库查看表格
