Satheesh Bandaram commented on DERBY-591:
-----------------------------------------

THANKS for filing this one... This has been wrong for a sometime.

I think non-escaped functions should be added to miscBuiltins() and escaped functions that could also be SQL operators should have been part of miscBuiltinsCore(). But looks like most recently added SQL only operators where put in miscBuiltinsCore() by mistake.

>          URL: http://issues.apache.org/jira/browse/DERBY-591
>      Project: Derby
>         Type: Bug
>     Versions: 10.0.2.0, 10.1.1.0
>     Reporter: Daniel John Debrunner
>     Priority: Minor

>
> Due to lack of direction in the way functions are added into the parser, any functions that are added into the parser's miscBuiltinsCore are also automatically JDBC/ODBC escaped functions.
> E.g. the new XML functions (e.g. XMLPARSE), COALESCE, VALUE etc. etc.
> The correct set of escaped scaler functions is defined in appendex C (C1- C5)  of JDBC 3.0.
> Discovered this while trying to make the JDBC escape functions table driven, at least for the valid subset of table driven functions added in DERBY-475.
> Probably just need to split the miscBuiltins core into two functions, one for functions that are SQL and allowed in JDBC escape, and one for ones only allowed in SQL.
