---------------------------------------

    Assign To: Satheesh Bandaram

> Several builtin functions are incorrectly exposed through the JDBC escaped function syntax
{fn <function_call>}
> ---------------------------------------------------------------------------------------------------------------
>
>          Key: DERBY-591
>          URL: http://issues.apache.org/jira/browse/DERBY-591
>      Project: Derby
>         Type: Bug
>   Components: JDBC, SQL
>     Versions: 10.0.2.0, 10.1.1.0
>     Reporter: Daniel John Debrunner
>     Assignee: Satheesh Bandaram
>     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.
