In which join all the rows from the left table appear in the output irrespective of the content of the other table?

Solution (By Examveda Team)

This question is about different types of joins used in SQL, specifically in MySQL. Joins help us combine data from two or more tables based on a common column. Let's break down the options:

Option A: RIGHT JOIN
In a right join, the result includes all rows from the right table, and matching rows from the left table. If there's no match, the left table will have null values.

Option B: LEFT JOIN
This is the correct answer! A left join shows all rows from the left table, and matching rows from the right table. If there's no match, the right table will have null values. This means all rows from the left table are guaranteed to be in the output, regardless of the content of the right table.

Option C: INNER JOIN
An inner join only shows rows where there's a match in both the left and right tables. If there's no match, the row is not included in the output.

Option D: OUTER JOIN
An outer join is a general term for both left and right joins. It's not specific to showing all rows from one table.

So, the answer is Option B: LEFT JOIN because it guarantees that all rows from the left table will appear in the output, regardless of the content of the right table.
