DISTINCT and its counterpart, ALL, can be used together on single field in a SELECT statement.
Answer
False
Reason — In SQL, DISTINCT
and ALL
cannot be used together on a single field in a SELECT
statement. As DISTINCT
eliminates duplicate rows from the results, while ALL
includes all rows, including duplicates. Therefore, attempting to use them together on the same field would result in a syntax error.
