Which three statements about subqueries are true? (Choose three)
A)A single row subquery can retrieve only one column and one row.
B)A single row subquery can retrieve only one row but many columns.
C)A multiple row subquery can retrieve multiple rows and multiple columns.
D)A multiple row subquery can be compared by using the “>” operator.
E)A single row subquery can use the IN operator.

ANSWER: TK says B,C,D
I'm sure that options B and C are correct. But I can't find any other correct answer in the question. What do you think? |
