Question
What is the use of subquery?

Answers

Subqueries provides you a more flexible option to filter the data as compared to an ordinary query filter. Using Subqueries you can limit the values returned with a WHERE clause. You can also compare the values of objects in a subquery with the other objects.
Using Subqueries, you can implement complex logic to limit the size of data which are not possible to apply with simple query filters.   Your Comment
