php同步mysql两个数据库中表的数据

分别创建两个数据库和两张表

study库-zone表

teaching库-area表

//****sql脚本****//

1.创建teaching数据库area数据表

create database teaching;

CREATE TABLE  `area` ( 

 `id` int(11) NOT NULL AUTO_INCREMENT, 

  `areaID` varchar(50) CHaraCTER SET utf8 DEFAULT NULL, 

 `area` varchar(60) CHaraCTER SET utf8 DEFAULT NULL, 

  `father` varchar(6) CHaraCTER SET utf8 DEFAULT NULL, 

 PRIMARY KEY (`id`)) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=3187 ;

2.给area表中添加数据

INSERT INTO `area` (`id`,`areaID`,`area`,`father`) VALUES 

(2759,'610101','市辖区','610100'),(2760,'610102','新城区', 

(2761,'610103','碑林区',(2762,'610104','莲湖区', 

(2763,'610111','灞桥区',(2764,'610112','未央区', 

(2765,'610113','雁塔区',(2766,'610114','阎良区', 

(2767,'610115','临潼区',(2768,'610116','长安区', 

(2769,'610122','蓝田县','610100');

3.创建study数据库zone数据表

create database study; 

CREATE TABLE `zone` ( 

 `id` int(11) NOT NULL AUTO_INCREMENT, 

`areaID` varchar(50) CHaraCTER SET utf8 DEFAULT NULL, 

  `area` varchar(60) CHaraCTER SET utf8 DEFAULT NULL, 

`father` varchar(6) CHaraCTER SET utf8 DEFAULT NULL, 

  PRIMARY KEY (`id`)) ENGINE=MyISAM  DEFAULT CHARSET=utf8 AUTO_INCREMENT=3187 ;

PHP文件执行数据表同步

<?PHP

$conn = MysqLi_connect('localhost','root','','study');

 

$delsql="Dalete from `zone`";

$rel_del = MysqLi_query($conn,$delsql);

$sql = "insert into study.zone(`id`,`father`) select `id`,`father` from teaching.area order by id asc";

$result = MysqLi_query($conn,$sql);

 

if($result){

echo "<font color='green'>恭喜恭喜，数据同步成功</font>";

}else{

echo "<font color='red'>对不起，数据同步出错，请检查!</font>";

} 

?>
