> Queries similar to {{SELECT 1 UNION SELECT 2, 3}} causes validator to throws a {{NullPointerException}} instance instead of a proper error message about the column count mismatch.
> {{SqlUtil#getSelectListItem}} is used by Set operators to get select items if the types of operands don't match. Unfortunately the method may throw an NPE exception if one of the operand doesn't have a FROM clause.
