1.如果2张表的字段一致，并且希望插入全部数据，可以用这种方法：
INSERT INTO 目标表 SELECT * FROM 来源表;
insert into insertTest select * from insertTest2;
2.如果只希望导入指定字段，可以用这种方法：
INSERT INTO 目标表 (字段1, 字段2, ...) SELECT 字段1, 字段2, ... FROM 来源表;(这里的话字段必须保持一致)
insert into insertTest2(id) select id from insertTest2;
3.如果您需要只导入目标表中不存在的记录，可以使用这种方法：
INSERT INTO 目标表
(字段1, 字段2, ...)
SELECT 字段1, 字段2, ...
FROM 来源表
WHERE not exists (select * from 目标表
where 目标表.比较字段 = 来源表.比较字段);
1>.插入多条记录：
insert into insertTest2
(id,name)
select id,name
from insertTest
where not exists (select * from insertTest2
where insertTest2.id=insertTest.id);
(id,name)
select id,name
from insertTest
where not exists (select * from insertTest2
where insertTest2.id=insertTest.id);
2>.插入一条记录：
insert into insertTest
(id, name)
SELECT 100, 'liudehua'
FROM dual
WHERE not exists (select * from insertTest
where insertTest.id = 100);
(id, name)
SELECT 100, 'liudehua'
FROM dual
WHERE not exists (select * from insertTest
where insertTest.id = 100);
