| Jason Beck writes "In a certain product database, SKUs of products listed by individual price start with a letter, while SKUs of products listed by case price start with a number. If the product is listed by individual price, I use a field ("list_price") to determine the price of an individual piece. If the product is listed by case price, I use a different field ("low_price") and the number of items in a case ("outerpack") to determine case price. Unfortunately, I don't have control over the design of the database, so in each query, I have to decide whether to use low_price or list_price, and in most cases, they both have a value, but the only valid value is the one following the rule I explained above. All I really need to know is a way to find out if SKU begins with a letter or a number, but I don't know of a way to do that in SQL." |
