Question 3In the following query, which join returns all records from the employees table, but only records that match on employee_id from the machines table?SELECT *FROM employees _____ machines ON employees.employee_id = machines.employee_id;1 pointRIGHT JOINFULL OUTER JOINLEFT JOININNER JOIN
Solution
The correct answer is LEFT JOIN.
In a SQL query, a LEFT JOIN returns all the records from the left table (in this case, the employees table), and the matched records from the right table (the machines table). If there is no match, the result is NULL on the right side.
