If price is a string beginning with '$', MySQL will autoconvert
SubString(price,2) to a numeric iif it's in a numeric expression, but
you'd be much better off losing the leading '$' chars and converting the
column to Decimal.

| $21.59 |

When I use SELECT title_id, ytd_sales * price From titles;
I get:
| title_id | ytd_sales | price * ytd_sales |

It appears that mysys 4.1 does not know how to multiply a dollar
amount to another number. Has anyone else seen this problem?
