1.创建测试的表 CREATE TABLE mytable ( id INT auto_increment NOT NULL, NAME VARCHAR (100) NOT NULL DEFAULT '', introduce text NOT NULL, createtime TIMESTAMP NOT NULL, CONSTRAINT pk_mytable PRIMARY KEY (id)) : 2.创建存储过程,这里的存储过程主要提供给mysql的定时器even…
mysql定时器是系统给提供了event,而oracle里面的定时器是系统给提供的job.废话少说,下面创建表:create table mytable (id int auto_increment not null,name varchar(100) not null default '',introduce text not null,createtime timestamp not null,constraint pk_mytable primary key(id)) 创建存储过程,这…
1.前置条件,你需要将服务器和mysql的时间都设置成东八区,php.ini和my.cnf配置(参考上篇文章) 2.进入mysql客户端,推荐Navicat for mysql 3.首先查看是否开启了定时器的功能: ####调试MYSQL定时器 --时间设置正确情况下执行下面没影响 xzz1128 ##### set time_zone = '+8:00'; SHOW VARIABLES LIKE 'event_scheduler';##查看是否开启了event定时器功能 set GLOBAL…
相同的表数据在sqlserver和MySQL中使用各自的函数得到相同的结果,如下表 drop table tb;create table tb(id int, value1 varchar(10), value2 varchar(20));insert into tb values(1,'aa','11');insert into tb values(1,'bb','22');insert into tb values(2,'aaa','111');insert into tb values(2…
1.复制表(包括表结构.表数据) SqlServer: Select * into user_copy from user MySql: CREATE TABLE user_copy LIKE user; INSERT INTO user_copy SELECT * FROM user; 2.多表连接做update SqlServer: UPDATE s1 SET s1.salary= s2.salary FROM (SELECT * FROM s WHERE age>10) AS s1 JOI…
