Excellent article - For more fun, check other DBMSes. I checked on Oracle and "select 'A' from dual where 1=0 or 1/0 = 1;" gives a division by zero error. (although it may need to be in a procedure on Oracle to do it with the IF statement). Anyone have DB/2 or Teradata handy?
You did the wrong test. You should have done "where 1=0 AND 1/0 = 1" or "where 1=1 or 1/0 = 1". Remember: AND short-circuits on false, OR short-circuits on true.
I am, however, interested in what you find out -- and we shouldn't necessarily limit the testing to DBMSes -- any system or language that evaluates boolean expressions can be tested for this behavior.
