Use Variables to Insert Data

In this example, a user is asked for three kinds of variables: Character, Date & Number. They are then inserted into an 'INSERT INTO' statement. (In entering the date, the year is assumed to be the current one.) After insertion, a SELECT is performed to show the user the data entered as it is in the table.
