I need to CAST a varchar field (Product Number)  that has product numbers that always start with a "BP_some number" into an INT for just the numeric part. For example, if I have the product number BP_4361, I need to CAST this so that I have 4361 as a resulting INT.
Hope this makes sense.
Best regards,
W Delaney
