关于node.js操作mysql数据库的相关介绍请阅读全文吧。下文介绍的非常详细，具体内容如下所示：

安装mysql模块

npm install mysql

数据库准备

mysql server所在的机器IP地址是192.168.0.108，登录账户就用root@123456

在mysql中创建test数据库

在test数据库中创建一张users表

操作

连接数据库

var mysql=require('mysql');

var connection = mysql.createConnection({

host : '192.168.0.108',user : 'root',password : '123456',database : 'test1',port:'3306'

});

connection.connect();

插入一个user

var usr={name:'zhangsan',password:'pwdzhangsan',mail:'zhangsan@gmail.com'};

connection.query('insert into users set ?',usr,function(err,result) {

if (err) throw err;

console.log('inserted zhangsan');

console.log(result);

console.log('\n');

});

更新user，带条件

connection.query('update users set password="ddd" where name="zhangsan"',{password:'ppp'},result) {

if (err) throw err;

console.log('updated zhangsan\'s password to ddd');

console.log(result);

console.log('\n');

});

删除一个user，带条件

connection.query('delete from users where name="zhangsan"',result) {

if (err) throw err;

console.log('deleted zhangsan');

console.log(result);

console.log('\n');

});

查询user，所有

connection.query('select * from users',rows,fields) {

if (err) throw err;

console.log('selected after deleted');

for(var i= 0,usr;usr=rows[i++];){

console.log('user nae='+usr.name + ',password='+usr.password);

}

console.log('\n');

});

关闭数据库连接

connection.end();

基本的CRUD完成

mysql模块的完整功能说明参见官方：

全部demo代码

var mysql=require('mysql');

var connection = mysql.createConnection({

host : '192.168.0.108',port:'3306'

});

connection.connect();

var usr={name:'zhangsan',result) {

if (err) throw err;

console.log('inserted zhangsan');

console.log(result);

console.log('\n');

});

connection.query('select * from users',fields) {

if (err) throw err;

console.log('selected after inserted');

for(var i= 0,password='+usr.password);

}

console.log('\n');

});

connection.query('update users set password="ddd" where name="zhangsan"',result) {

if (err) throw err;

console.log('updated zhangsan\'s password to ddd');

console.log(result);

console.log('\n');

});

connection.query('select * from users',fields) {

if (err) throw err;

console.log('selected after updated');

for(var i= 0,password='+usr.password);

}

console.log('\n');

});

connection.query('delete from users where name="zhangsan"',result) {

if (err) throw err;

console.log('deleted zhangsan');

console.log(result);

console.log('\n');

});

connection.query('select * from users',password='+usr.password);

}

console.log('\n');

});

connection.end();
