我想知道在node.js中使用更短或更优雅的方式来做mysql请求(使用池)
实际上这是我如何做多个请求(我简化了示例的代码,请参阅我的评论内容):
var Mysql = require('mysql');
//Creating the pool of sql connections
var Pool = Mysql.createPool({
host: Config.database.auth.host,
user: Config.database.auth.user,
password: Config.database.auth.pass,
name: Config.database.auth.name
});
//Using one of the connections available in the pool
PoolAuth.getConnection(function (e, c) {
if (e) {
//failed to use the connection
} else {
//Executing the first query
c.query("SELECT * FROM blabla WHERE id = ?", [1], function (e, r, f) {
//Releasing the connection, should i do that at this moment or before closing the pool ?
c.release();
if (e) {
//failed to exe the query
}
else {
//Executing second query
c.query("UPDATE blabla SET enabled = ? WHERE id= ?", [1, r[0].id], function (e, r, f) {});
}
});
}
});
能够做到这样的事情会更优雅,更干净:
var query = Pool->query("SELECT * FROM blabla WHERE id=?", [0]);
if(query) {
Pool->query("UPDATE blabla SET enabled = ? WHERE id=?", [1, query.id]);
}
(类似于我在PHP中所做的)
感谢您的帮助
