In this tutorial, you have learned how to insert one or more rows into an SQLite table from a Node.js application. It inserted 5 rows into the langs table which is what we expected. Rows inserted 5 Code language: JavaScript ( javascript ) INSERT INTO langs(name) VALUES (?),(?),(?),(?),(?) Updating data example To update data in a table, you use the UPDATE statement as follows: UPDATE tablename SET columnname value1 WHERE id idvalue Code language: JavaScript (javascript) To execute the UPDATE statement in the Node. Let’s run the insert-many.js program to see how it works. To execute an INSERT statement, you use the run() method of the Database object: db.run(sql, params, function( err)`) Now, we are ready to insert data into the langs table. Let db = new sqlite3.Database( './db/sample.db') ĭb.run( 'CREATE TABLE langs(name text)') You can run the program to create the sample.db database and langs table as follows: const sqlite3 = require( 'sqlite3').verbose() To get started, install databases/sqlite using either yarn or npm: yarn install databases/sqlite. if you are using node.js in IOT, or an Electron app. In the sample.db database, we create a table called langs for storing programming languages: db.run( 'CREATE TABLE langs(name text)') SQLite is a great database for embedded use cases. let db = new sqlite3.Database( './db/sample.db') When you open a database connection in the default mode, the database is created if it does not exist. To insert data into an SQLite table from a Node.js application, you follow these steps:įor the demonstration, we will create a new database named sample.db in the db folder. Summary: in this tutorial, you will learn how to insert one or more row into an SQLite table from a Node.js application.
