Learn how to write SQL (Structured Query Language) from scratch with the SQL Essentials training course. This course will easily step you through writing SQL using an online editor. SQL allows you to retrieve, sort, filter, group, aggregate and calculate data stored in a SQL Server database. This course is designed for people wanting to learn how to interrogate data from a relational database, how to manipulate this data (Insert, update, and delete records).
Although we use SQL Server to interrogate data throughout this course, SQL is a common language easily adapted to other RDBMS (relational database management systems) such as MySQL, IBM DB2, PostgreSQL, Oracle, Ingres, Sybase, and Microsoft Access.
