The join where all possible row combinations are produced is called . . . . . . . .

Solution (By Examveda Team)

This question is about different types of joins in SQL, specifically MySQL. Joins are used to combine data from multiple tables based on related columns. Let's break down each option:
Option A: INNER JOIN
An INNER JOIN returns only rows where there is a match in both tables. It essentially finds the intersection of the two tables.
Option B: OUTER
OUTER is not a specific type of join itself. It's a general term for joins that include rows from one table even if there's no match in the other table. There are two types of OUTER joins: LEFT OUTER JOIN and RIGHT OUTER JOIN.
Option C: NATURAL
A NATURAL JOIN automatically joins tables based on columns with the same name, creating a join condition based on matching column names.
Option D: CARTESIAN
A CARTESIAN JOIN produces all possible combinations of rows from the two tables, regardless of whether there are matching values. It's like multiplying the number of rows in each table. This is often called a "cross join".
Therefore, the correct answer is Option D: CARTESIAN. A CARTESIAN JOIN creates all possible combinations, resulting in every row from one table being combined with every row from the other table.
