Hi, I have a "discount" table that carries percentage discounts that should be looked up when the customer submits a discount code and taken into calculation of the total price. My table looks something like this:
field names: |senior|student|... values: |0.20|0.50|... Now, when the senior writes in the textfield "senior"(as a discount code), everything is fine since my SELECT query looks up $discount field (which in this case is "senior") and returns 0.20. However, if by mistake he misspells "senor" instead of "senior" (or tries to make up a discount code) he will get an error, because there is no such field in my MySQL table. How can I catch that error (such discount doesn't exist) and have perl do something? thanks, Mariusz ps. My Select query looks up bunch of other stuff at the same time, but I guess I could separate them into two and maybe react to the error caused during discount lookup and have perl continue... but how can I do that? How can I separate the error "such field doesn't exist" from any other error in MySQL? Would "prepare" stop the script the same way "selectrow_array" does?
