Julian Hyde commented on DRILL-1316:
------------------------------------
As you can see from all the <LBRACE_FN> tokens listed in the stack trace,
Optiq's parser does support {fn ...} syntax. It just doesn't support {fn
FLOOR}. It would be useful to know which "fn" functions Tableau expects.
> Drill does not support the "fn" syntax generated from Tableau
