Well, don't divide by zero! Use DECODE function and choose either a very large value, or a very small value. For example:

SELECT square_footage / DECODE(sales_price, 0, 1E99) 
FROM TEST;

This will produce a very small result (pratically 0).

Your could also do

SELECT decode(sales_price,0,0,square_footage /sales_price)
FROM TEST;

I like converting it to NULL

SELECT square_footage / NULLIF(sales_price,0)
