mssql-dbOperations

The mssql-dbOperations package provides a simplified interface for performing database operations on Microsoft SQL Server databases. It encapsulates connection handling, query execution, and basic CRUD operations into a reusable and modular class.

Features

• Connection pool management.
• Automated reconnection on connection loss.
• Simplified query execution with parameter support.
• CRUD operations including check existence, fetch, insert, update, and delete records.
• Truncate table functionality.

Installation

Install the package using npm:

npm install mssql-dboperations

Configuration

const config = { user: 'yourUsername', password: 'yourPassword', server: 'yourServerAddress', // You can use 'localhost\instance' if your SQL Server runs on the same machine but using a named instance database: 'yourDatabaseName', options: { encrypt: true, // Use this if you're on Windows Azure enableArithAbort: true } };

Creating an Instance

const Database = require('mssql-dboperations'); const db = new Database(config);

Checking if a Record Exists

async function checkExistence() { const exists = await db.isExist("TableName", "ColumnName", "ValueToCheck"); console.log('Existence:', exists); } checkExistence();

Get Database Values

async function fetchValues() { const records = await db.getDBValues('Employees', 'Name'); console.log('Employee Names:', records); } fetchValues();

Inserting Values into a Table

async function insertValues() { const resultId = await db.insertDBValues('Employees', { Name: 'John Doe', Position: 'Software Engineer' }); console.log('Inserted Record ID:', resultId); } insertValues();

Update Values

async function updateValues() { const success = await db.updateDBValues('Employees', { Position: 'Senior Engineer' }, "EmployeeId = 123"); console.log('Update Success:', success); } updateValues();

Update Values

async function clearTable() { await db.truncateTable('TemporaryData'); console.log('Table truncated successfully.'); } clearTable();
