Consider the table Professor with attributes Id, Name, Dept, Salary, and Rank and primary key Id, and the statements:
where ssn is a host variable and sal is a literal.
(a) Give an ecient query plan for S1 and state what index (search key, clustered, nonclustered,
B+ tree, hash) is used.
(b) Now suppose, in addition to optimizing S1, we are equally concerned with optimizing the
execution of S2. Assuming sal is a large number (most rows do not satisfy the WHERE
clause) describe the query plan you would like the optimizer to use and any changes that
might need to be made to your previous answer. State what index (search key, clustered,
nonclustered, B+ tree, hash) is used for each statement. Explain your reasoning.
(c) Redo the previous part assuming that sal is a small number (most rows satisfy the
WHERE clause). Explain your reasoning.
