Thanks !!
Do we need to look at the in list types in this case ? The in list types
could be literals of different types , right ? for example NULL not in (1, 'a')
Since the result of IN predicate is a boolean type, i thought it would be
safe to transform it to
a Null literal of boolean type. Are you thinking of a case where this would
not work ?
Thanks a lot in advance for your help.
