How to Work with Databend in Node.js | ||
--- | ||
|
||
### Before You Begin | ||
|
||
* **Databend :** Make sure Databend is running and accessible, see [How to deploy Databend](/doc/deploy). | ||
* Install the mysql node module using the NPM: npm install --save mysql | ||
|
||
### Node.js | ||
|
||
This guideline show how to connect and query to Databend using Node.js. | ||
|
||
We will be creating a table named `books` and insert a row, then query it. | ||
|
||
```js | ||
const mysql = require('mysql'); | ||
const con = mysql.createConnection({ | ||
host: 'localhost', | ||
port: 3307, | ||
user: 'root', | ||
password: '', | ||
}); | ||
|
||
con.connect((err) => { | ||
if (err) throw err; | ||
console.log('Connected to Databend Server!'); | ||
|
||
var sql = "create database if not exists book_db"; | ||
con.query(sql, function (err, result) { | ||
if (err) throw err; | ||
console.log("Dataabse created"); | ||
}); | ||
|
||
var sql = "use book_db"; | ||
con.query(sql, function (err, result) { | ||
if (err) throw err; | ||
}); | ||
|
||
|
||
var sql = "create table if not exists books(title varchar(255), author varchar(255), date varchar(255))"; | ||
con.query(sql, function (err, result) { | ||
if (err) throw err; | ||
console.log("Table created"); | ||
}); | ||
|
||
var sql = "insert into books values('mybook', 'author', '2022')"; | ||
con.query(sql, function (err, result) { | ||
if (err) throw err; | ||
console.log("1 record inserted"); | ||
}); | ||
|
||
con.query("select * from books", function (err, result, fields) { | ||
if (err) throw err; | ||
console.log(result); | ||
}); | ||
|
||
}); | ||
``` | ||
|
||
The output: | ||
```shell | ||
Connected to MySQL Server! | ||
Dataabse created | ||
Table created | ||
1 record inserted | ||
[ RowDataPacket { title: 'mybook', author: 'author', date: '2022' } ] | ||
``` |
