Question

The All option can be used in the Select clause to indicate that all columns should be retrieved.

A) True
B) False

Answer 1

The statement is false; to retrieve all columns in SQL, you use the asterisk (*) symbol with the Select clause, not the All option.

Step-by-step explanation:

The statement that the All option can be used in the Select clause to indicate that all columns should be retrieved is false. In SQL, the correct symbol to use when you want to retrieve all columns from a table is the asterisk (*) symbol. Therefore, in the Select clause of a SQL query, you would use Select * to indicate that all columns of the table should be retrieved. The All keyword in SQL is actually used for a different purpose, which is to return all rows, including duplicates, when used with set operations like UNION ALL.
