Hello: Can someone clarify this for me?
In "CASE a WHEN b THEN c [ELSE f] END", are the following rules necessary? 1. a and b should have the same TypeInfo, or an exception will be thrown. 2. c and f should have the same TypeInfo, or an exception will be thrown. Right now, even if c is int, f is smallint, it throws exception. Please let me know whether such restriction is there by design. Thank you very much! Xiu
