What allows nesting one select statement into another?

Solution (By Examveda Team)

Imagine you have a box of toys, and you want to find a specific toy inside. You can't just look at the whole box at once, so you need to open it and check each toy individually.

This is similar to how subquerying works in MySQL. It lets you perform a query within another query, like looking inside a box to find a specific toy.

Here's an example: you want to find the names of employees who work in the department with the highest average salary. You can use a subquery to first find the department with the highest average salary, and then use that information to find the employee names.

So, the answer to the question is Option C: subquerying.

Let's break down the other options:

Option A: nesting - While nesting is related to putting things inside each other, it's a general term and doesn't specifically describe this concept.

Option B: binding - Binding refers to associating values with variables in SQL statements, not to nested queries.

Option D: encapsulating - This is also a general term and doesn't directly relate to how nested queries work.

Therefore, subquerying is the correct answer. It's like opening a smaller box inside a bigger box to find what you're looking for.
