1.binlog format 启用Row Based Replication(行复制)模式: SET GLOBAL binlog_format = 'ROW'; 如果你想永久的启用这个模式,请修改my.cnf 配置文件: [mysqld] binlog_format=ROW 2.在执行你的sql语句前,设置当前会话的隔离级别 SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED; INSERT INTO t1 SELECT ....;
insert or replace:如果不存在就插入,存在就更新insert or ignore:如果不存在就插入,存在就忽略只对UNIQUE约束的字段起作用.举例:建表:CREATE TABLE TEST(id BIGINT, name text, birthday datetime, PRIMARY KEY(id, name));或者CREATE TABLE TEST (id BIGINT, name text, birthday datetime, UNIQUE(id, name));插入
