1.相同表结构

INSERT INTO table1 SELECT * FROM table2;

2.不同表结构

INSERT INTO table1(filed1,…,filedn) SELECT table2.filed1,table2.filedn FROM table2;

3.如果是不同数据库之间，参考以下：

INSERT into db_ds_edu.t_exam_student(stu_id,stu_number,stu_name,school_id,campus_id,grade_id,class_id,xuebu_id) SELECT stu.id,stu.student_num,person.name,stu.school_id,stu.campus_id,stu.grade_id,stu.clas_id,stu.xuebu_idFROM db_ds.t_stu_info AS stu,db_ds.t_p_person_info as person WHERE stu.person_id = person.id——————— 作者：清无时空 来源：CSDN 原文：https://blog.csdn.net/sinat_34439107/article/details/70214335 版权声明：本文为博主原创文章，转载请附上博文链接！
