1. We wish to create a Student Table containing the student ID number, name, address, and telephone. The student ID is designated as the primary key. Write SQL statements to create the table and grant the select right to user Alice.

2. Consider a database table that includes a salary attribute. Suppose the three queries sum, count, and max (in the order) are made on the salary attribute, all conditioned on the same predicate involving other attributes. That is, a specific subset of records is selected and the three queries are performed on that subset. Suppose the first two queries are answered, and the third query is denied, Is any information leaked?
