(mysql不支持 select into from )


方法一:在mysql中用select into from报错

select into from与insert into select区别 - 图1
错误:1327 - Undeclared variable: score
select into from要求目标表target_table不存在,因为在插入时会自动创建
后来在网上看资料说Mysql不支持select into from语句,所以用其他方法来替代select into from语句:
create table score1 (select num from student);
select into from与insert into select区别 - 图2
查询表score1:
select into from与insert into select区别 - 图3

方法二:

INSERT INTO table_1 (SELECT * FROM table_2)
把table_2数据转存到table_1,此方法适合table_1已经创建的。
