Mysql的语句

我们可以先把test下的t1表的结构导出来,然后新建立一个test1.t1表。

执行下面语句

insert into test1.t1 select * from test.t1 limit 2 (limit限制条数)

如果在一个中就是



insert into t1 select * from t2 limit 2

如果表结构不一样的两张表,可以考虑、、参考下面的语句

 

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_id 
FROM 
  db_ds.t_stu_info AS stu 
    ,db_ds.t_p_person_info as person 
    WHERE stu.person_id = person.id 

 

 

insert into test1.t1 select * from test.t1 limit 2
