用的是 node.js 连接 mysql 数据库
代码如下
var mysql = require(‘mysql’);
var connection = mysql.createConnection({
user : ‘x x x’,
password : ‘x x x’,
database : ‘x x x’
});
connection.connect(function(err){
if(err){
console.log(err);
return;
}
})
var addSql = ‘INSERT INTO user(id,name) VALUES(0,?)’;
var addSqlParams = [‘菜鸟工具’];
connection.query(addSql,addSqlParams);
connection.end();
报错信息
