pengzhiwei commented on CALCITE-2977:
-------------------------------------
I prefer to allow the case that the ambiguous field is not referenced and throw
exception for that is referenced.A PR is made for this issue,please have a
review,thanks!
PS: I also fix same test case which enable the _CaseSensitive_ to _true_ ,But
use the default _UnquotedCasing TO_UPPER,_ which make all identifier to upper
and make the test for case-sensitive no meaning.
