Rong Rong commented on CALCITE-2721:
------------------------------------
Hi folks. I just added some tests to verify and see which part of the parser is
missing.
For example, the following expression: {{my_column.my_member_func(my_arg)}},
seems to be resolved as:
{code:java}
operator = {SqlUnresolvedFunction@1718} "my_member_func"
category = {SqlFunctionCategory@1723} "USER_DEFINED_FUNCTION"
sqlIdentifier = {SqlIdentifier@1724} "my_column.my_member_func"
paramTypes = null
name = "my_member_func"
operands = {SqlNode[1]@1719}
0 = {SqlIdentifier@1729} "my_arg"
{code}
Was this want we want out from the parser?
