select round(CASE QtyFld < 0 THEN 0 ELSE QtyFld END * PriceFld, 2) as TotalPriceFld
       from invoice

(not tested, but should works)

>>>Is there a way to use the MAX function in a SQL statement (as opposed to the documented MAX "field function" that calculates the largest value in a column). To be more specific, for any particular record, I need to multiply the value in a field by the value in another field. However, the value in the first field will sometimes be negative 1 and in that case I don't want to multiply negative one by the value in the other field, I want to multiply 0 by the value in the other field.

>>>

>>>select round(QtyFld * PriceFld, 2) as TotalPriceFld;
>>>	from invoice;
>>>	into cursor TestCursor

>>>But if I change QtyFld to max(0, QtyFld) then I get an error during compile that says "function is missing ')'". VFP seems to be thinking I want to use the MAX "field function." Here's the code that doesn't work.

>>>select round(max(0, QtyFld) * PriceFld, 2) as TotalPriceFld;
