我不知道为什么mysql.end()或mysql.destroy()不能正常工作。这是我的代码。
var mysql = require('mysql');
var connection = mysql.createConnection({
host: 'localhost',
user: 'root',
database: 'db',
password: ''
});
connection.connect();
connection.query('SELECT * FROM ofertas ', function (err, rows, fields)
{
if (err) console.log(err);
else
{
console.log(rows);
}
});
connection.destroy(function (err)
{
if (err) throw err;
});
我执行此代码,然后我转到mysql命令行,我输入:
show status like 'Conn%';

您需要等到查询完成才能销毁连接。尝试
connection.query('SELECT * FROM ofertas ', function (err, rows, fields)
{
if (err) console.log(err);
else
{
console.log(rows);
}
connection.destroy();
});
