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 insertTest2mysql 操作杂记
