代码如下：
var mysql = require('mysql');
var conn = mysql.createConnection({
host:'localhost',
user:'root',
password:'',
database:'cluster_manager_dev',
port:3306
});
conn.beginTransaction(function(err) {
if(err) {
throw err;
console.log(err);
}
conn.query('insert into user set user_name = ?, password = ?, is_admin = ?', ['testkjk', '123456', '2'], function(err, result) {
if(err) {
conn.rollback(function() {
console.log('first insert into user');
throw err;
});
}
conn.query('insert into user', function(err, result) {
if(err) {
console.log('second insert into user');
conn.rollback(function() {
throw err;
});
}
conn.commit(function(err) {
console.log('enter the commit');
if(err) {
conn.rollback(function() {
throw err;
});
}
console.log('success');
});
});
});
});
最终的结果第一条语句执行了，向数据库中插入了testkjk，而且程序也打印了 second insert into user， 而没有回滚，这是为什么呢？
附上程序执行错误输出：
second insert into user

@ravenwang 亲 不加return确实会执行后面的语句，我加了return之后，第一条插入sql还是执行了，官方给的例子上页木有return，疑惑啊 附上链接：https://github.com/felixge/node-mysql#transactions
