SQL joins combine rows from two or more tables based on a related column. Here are the different types of joins you can use:
Returns only the matching rows between both tables. It keeps common data only.
Returns all rows from the left table and matching rows from the right table. If a row in the left table doesn’t have a match in the right table, the right table’s columns will contain NULL values in that row.
Returns all rows from the right table and matching rows from the left table. If no matching record exists in the left table for a record in the right table, the columns from the left table in the result will contain NULL values.
Returns all rows from both tables, filling in NULL for missing matches.
