One of the complexities that is of a specific importance to this section is comparisons that potentially involve NULL comparands, such as ones that you use in filter and join predicates. Most operators that you use in such comparisons, including the equals (=) and different than (<>) operators, use three-valued logic.

In Part 1 I covered the meaning of the NULL marker and how it behaves in comparisons. In Part 1 in the series I explained how NULLs behave in comparisons and the complexities around the three-valued predicate logic that SQL and T-SQL employ. Often in practice you want NULLs to behave just like non-NULL values for comparison purposes.
