SQL LEFT JOIN

SQL LEFT JOIN

The LEFT JOIN keyword returns all rows from the left table (table1), with the matching rows in the right table (table2). The result is NULL in the right side whenthere is no match.

SELECT column_name(s)
FROM table1
LEFT JOIN table2

ON table1.column_name=table2.column_name;
