Node script to test connection to database

NodeDBTest

This repository contains Node.js scripts to establish database connections for both MySQL and Microsoft SQL Server (MSSQL). These scripts can be used to verify the connectivity to the respective databases and serve as a starting point for performing various database operations.

Prerequisites:

1. Node.js and npm should be installed on your system.
2. Ensure you have a running and accessible MySQL server for the MySQL script.
3. Ensure you have a running and accessible Microsoft SQL Server for the MSSQL script.

Setup:

1. Clone the repository or download the script files (mysql_connection.js and mssql_connection.js).
2. For each script, install the required dependencies by running the following commands in your project directory:

   # For MySQL Script
   npm install mysql2
   
   # For MSSQL Script
   npm install mssql

3. Modify the connection_config.js file for both scripts with your respective database connection details (host, port, user, password, and database).

Connection Configuration:

• The connection_config.js file contains the necessary configuration for connecting to the databases. Update the following details in the file:

// connection_config.js

const connection_config = {
  host: 'server-name-or-ip',
  port: 3306, // Replace this with the appropriate port for your MySQL server
  user: 'username',
  password: "password",
  database: "database-name",
};

module.exports = connection_config;

MySQL Script:

• File: mysql_connection.js
• Description: This script establishes a connection to a MySQL database using the mysql2 package in Node.js. It reads the connection details from the connection_config.js file and performs a basic connection test.
• Usage:

  node mysql_connection.js

• Outcome:
  • If the connection is successful, it will display "Connected to MySQL server!" in the console.
  • If there's an error during the connection attempt, it will display an error message indicating the issue.

MSSQL Script:

• File: mssql_connection.js
• Description: This script establishes a connection to a Microsoft SQL Server (MSSQL) database using the mssql package in Node.js. It reads the connection details from the connection_config.js file and performs a basic connection test.
• Usage:

  node mssql_connection.js

• Outcome:
  • If the connection is successful, it will display "Connected to Microsoft SQL Server!" in the console.
  • If there's an error during the connection attempt, it will display an error message indicating the issue.

Note:

• Ensure that the respective database servers (MySQL and MSSQL) are running and accessible with the provided connection details.
• If you encounter any issues during the connection process, double-check the configuration settings and ensure the database servers are accessible from your environment.
• Review the options object in the mssql_connection.js script if you are connecting to a non-standard SQL Server setup, as it might need adjustments.

Feel free to extend these scripts to perform additional database operations based on your requirements. Happy coding!
