What query does he need to write to retrieve the information?

A WHERE clause in SQL specifies that a SQL Data Manipulation Language (DML)
statement should only affect rows that meet specified criteria. The criteria are expressed in
the form of predicates. WHERE clauses are not mandatory clauses of SQL DML statements,
but can be used to limit the number of rows affected by a SQL DML statement or returned by a query.

A pen tester is trying to gain access to a database by inserting exploited query statements
with a WHERE clause. The pen tester wants to retrieve all the entries from the database
using the WHERE clause from a particular table (e.g. StudentTable).
