The one-day Introduction to SQL course provides the essential knowledge and skills needed to retrieve and work with data stored in relational databases. You will begin by exploring core database concepts, including tables, rows, columns, primary and foreign keys, indexes and data types, before learning how SQL can be used to query structured data.
You will learn how to write SELECT statements, filter and sort results, perform calculations and use aggregate functions to summarise data. The course also introduces GROUP BY and HAVING clauses, inner and outer joins, self joins, basic subqueries and set operators, giving you a solid foundation for working with SQL across a range of relational database platforms.
