I have 2 issues with constraints in Oracle 9i that I can't find out how to do.
1. Middle initial must be null, blank, or capital-A through capital-Z
2. INV_SIZE must be null, blank, a one or two digit number, S, M, L, XS, XL, XXS, XXL, 3XS, 3XL, 4XS, 4XL, … 9XS, 9XL
What would be the best way to put these constraints on my columns?
Thank you for your help!!
