The 4 Types of SQL Joins SQL joins combine rows from two or more tables based on a related column. Here are the different types of joins you can use: 1 - Inner Join Returns only the matching rows between both tables. It keeps common data only. 2 - Left Join 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. 3 - Right Join 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. 4 - FULL OUTER JOIN Returns all rows from both tables, filling in NULL for missing matches.
