What is SQL Join Types Explained about?

SQL joins are used to combine data from two or different tables. The main types of joins are inner joins, left joins, right joins, and full joins. Inner joins return rows when there is a match in both tables. Left joins return all rows from the left table even if no matches exist in the right table. Right joins are the opposite, returning all rows from the right table. Full joins return rows when there is a match in either table.
