Introduction to SQL

Q1:

The wildcard in a WHERE clause is useful when?

A An exact match is necessary in a SELECT statement.

B An exact match is not possible in a SELECT statement.

C An exact match is necessary in a CREATE statement.

D An exact match is not possible in a CREATE statement.

ANS:B - An exact match is not possible in a SELECT statement.

"The wildcard in a WHERE clause" makes no sense whatsoever. The WHERE clause has not "wildcards". The LIKE operator supports wildcards, but not the WHERE clause (and together with CREATE the term wildcard makes even less sense).
