The SELECT statement
SELECT A FROM T WHERE Paccesses a table, T, with attributes A, B, C and K, where K is the primary key, and P is a predicate. The values of all attributes are randomly chosen over the integer domain. Since the table is updated frequently, there is a limitation of at most one clustered and one unclustered index. In each of the following parts choose the indexes (type, search key, clustered or unclustered) to optimize the SELECT statement and maintain the primary key constraint when the value of P is as specied. In each case give the query plan you expect the DBMS to choose for the SELECT and the reason you think that plan is best. Do not use index covering. (a) P is (B = 10) (b) P is (B > 10) (c) P is (B > 10 AND C = 5) (d) P is (B > 10) and the WHERE clause is followed by the clause ORDER BY A
