Код ошибки: код ETIMEOUT
. Я использую SQL Server 2014, NodeJs версия v12.16.2 и запускаю этот код в коде Visual Studio.
Я создал базу данных, и таблица также создается с некоторыми записями. Что касается имени сервера, я также попытался указать полное доменное имя, но оно не сработало.
Это фрагмент кода:
const express = require('express');
const app = express();
var Connection = require('tedious').Connection;
var Request = require('tedious').Request;
app.get('/', function(req, res) {
res.send('<hHii</h');
});
const sql = require('mssql');
var config = {
user: 'domain\username',
password: 'mypwd',
server: 'servername',
host: 'hostname',
port: '1433',
driver: 'tedious',
database: 'DBname',
options: {
instanceName: 'instancename'
}
};
sql.connect(config, function(err) {
if (err)
console.log(err);
let sqlRequest = new sql.Request();
//var sqlRequest = new sql.Request(connection)
let sqlQuery = 'SELECT * from TestTable';
sqlRequest.query(sqlQuery, function(err, data) {
if (err) console.log(err);
console.log(data);
//console.table(data.recordset);
// console.log(data.rowAffected);
//console.log(data.recordset[0]);
sql.close()
});
});
const webserver = app.listen(5000, function() {
console.log('server is up and running....');
});
Ошибка:
tedious deprecated The default value for `config.options.enableArithAbort` will change from `false` to `true` in the next major version of `tedious`. Set the value to `true` or`false` explicitly to silence this message.
