Talk:Null (SQL)/to do


 * 1) Add a graphic.  Possibly a screenshot of a query with NULL in the results, or other relevant image.
 * 2) Continual copyediting and improvement.
 * 3) Please review for redundancies so we can eliminate them if necessary.
 * 4) Displaying the equality operator's truth table is wrong (like all "regular" comparison operators comparing against NULL always results in UNKNOWN, so the current truth table is a general operator truth table). The IS operator must be used with booleans.
