Question
Which of these is true of LEFT JOIN? (Select all that apply)1 pointAll records from the left table that have no matching record from the right table.It returns all matching records in both tablesAll records from the right table
Solution
The correct answers are:
- All records from the left table that have no matching record from the right table.
- It returns all matching records in both tables.
A LEFT JOIN in SQL returns all the records from the left table, and the matched records from the right table. If there is no match, the result is NULL on the right side. Therefore, it does not return all records from the right table, only the ones that match with records in the left table.
