This article is the second in a series on NULL complexities. Last month I introduced the NULL as SQL's marker for any kind of missing value. I explained that SQL doesn't provide you with the ability to distinguish between missing and applicable (A-values) and missing and inapplicable (I-values) markers. I also explained how comparisons involving NULLs work with constants, variables, parameters and columns. MORE
