Julian Hyde commented on CALCITE-2510:
--------------------------------------
I did an initial review. It looks OK:
* Is it necessary to add a keyword to the parser? (INITCAP is not a keyword,
and it parses fine because it uses ordinary function syntax.)
* In the reference, remove VARCHAR2 (that type is Oracle-specific). Mention
that the function is Oracle-only.
I'll need to do further testing. I'll mark if "fix in 1.18" so we don't forget.
