What is the join where all possible row combinations are produced?

Solution (By Examveda Team)

This question is asking about a type of join in MySQL. Joins are used to combine data from multiple tables based on a shared column.

Let's break down the options:

A. INNER JOIN: An INNER JOIN only returns rows where there is a match in both tables.
B. OUTER: This isn't a specific join type. It refers to LEFT OUTER JOIN or RIGHT OUTER JOIN, which include all rows from one table and matching rows from the other.
C. NATURAL: A NATURAL JOIN is similar to an INNER JOIN, but it automatically joins based on columns with the same name in both tables.
D. CARTESIAN: A CARTESIAN JOIN creates every possible combination of rows from both tables, even if there's no matching data. This can result in a very large result set!

The correct answer is D. CARTESIAN.
