SQL Fundamentals
Use SELECT, INSERT, UPDATE and DELETE with conditions, sorting and result limits.
Online MySQL Training for Practical Database Work
MySQL is a widely used relational database management system for storing and retrieving data in websites, content platforms and business applications. SQL allows developers to create tables, query records, combine related information and update data safely.
This course page presents a practical route into MySQL, from understanding table structure to writing queries that support application features. Learn how data is organised, how relationships are represented and how to reason about query results instead of relying on memorised syntax.
Create tables and choose appropriate data types
Write SELECT queries with filtering and sorting
Join tables and summarise data
Understand indexes, transactions and constraints
Who should start here? Beginners can start with relational database and SQL fundamentals. PHP and web developers can focus on using MySQL for application data, CRUD features and troubleshooting database queries.
