Talk:Null (SQL)/to do

Add a graphic. Possibly a screenshot of a query with NULL in the results, or other relevant image. Continual copyediting and improvement. Please review for red

  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.
