mysql> select 1 from dual where false;
Empty set (0.00 sec)

In the above query, “dual” is a dummy table and the above condition false. Therefore, it returns empty set.

Let us check with true condition. It will return the selected value. The query is as follows −

mysql> select 1 from dual where true;

The following is the output −
