Can you give me examples of query builders?
Sure! Query builders are tools that help you construct database queries programmatically. Examples include Laravel's Eloquent, Knex.js for Node.js, and SQLAlchemy for Python.
How does Laravel's Eloquent work?
Laravel's Eloquent is an ORM (Object-Relational Mapping) that allows you to interact with your database using PHP syntax. You can define models that represent your database tables and use methods to perform CRUD operations.
What are the advantages of using a query builder?
Using a query builder can simplify complex queries, improve code readability, and help prevent SQL injection attacks by using prepared statements.
Can you show me a simple example of a query using Knex.js?
Certainly! Here's a simple example: knex('users').select('*').where('id', 1)
retrieves all columns for the user with ID 1.
