You attempt to query the data base with this command:
SELECT name, salary FROM employee WHERE salary=(SELECT
salary FROM employee WHERE last name='Wagner' OR dept no=233)
Choose most appropriate option from the following:
1)Sub-queries are not allowed in the where clause.
2)a multiple row sub-query used with a single row comparison
3)a single row query is used with a multiple row comparison
