Table dropped.

Use the ALL operator in a WHERE clause to compare a value with all of the values in a list

You must place an =, <>, <, >, <=, or >= operator before ALL.

The following SELECT statement uses the ALL operator to retrieve rows from the employee table where the value in the id column is greater than all of the values 2, 3, and 4:
