JOIN Queries

JOIN queries are used to combine rows from two or more tables based on a related column between them. This allows you to retrieve data from multiple tables in a single query, forming a more comprehensive dataset than you could get from a single table alone. Different types of joins, like INNER, LEFT, RIGHT, and FULL OUTER, determine how rows are included in the result based on whether matching values exist in the related columns.
