egg.js报错不知道怎么解决

Question

module.exports = app => {
class UserService extends app.Service {
* show(i) {
const queryStr = 'show zc_user;';
const record = yield app.mysql.select(queryStr, '');
//yield this.app.mysql.query('select * from zc_user','');
return record;
}
}
return UserService;
};

## 这是我service里面的代码 调用之后报这个错误TypeError: app.mysql.select is not a function

Answer 1

没找到函数app.mysql.select，要么删掉了该函数，要么你没有添加一些相关的js文件
