Question

You issue the following SQL query: SELECT FirstName FROM StaffList WHERE FirstName LIKE '_A%'

Which names would be returned by this query? Choose all that apply.
a) Allen
b) CLARK
c) JACKSON
d) David

Answer 1

The SQL query selects first names with any single character followed by 'A' and then any characters. In the options given, only 'CLARK' meets these conditions.

Step-by-step explanation:

The SQL query SELECT FirstName FROM StaffList WHERE FirstName LIKE '_A%' retrieves all names from the StaffList where the FirstName starts with any single character (_), followed by an 'A', and then followed by zero or more characters (%). Among the provided options, only option (b) CLARK matches this pattern since it has a single character before the letter 'A' (which is 'C' in this case), and then one or more characters following 'A'.
