>                 Key: DERBY-5214
>                 URL: https://issues.apache.org/jira/browse/DERBY-5214
>             Project: Derby
>          Issue Type: Improvement
>          Components: JDBC, SQL
>    Affects Versions: 10.8.1.2
>            Reporter: Lukas Eder
>            Priority: Minor
>              Labels: derby_triage10_10, escape, function, sql, syntax
>
> Quite a few functions are supported in Derby's proprietary "JDBC escape syntax":
> http://db.apache.org/derby/docs/10.8/ref/rrefjdbc88908.html
> Most of those functions can also be used without that syntax, e.g.
> SELECT {fn abs(FIELD)}, abs(FIELD) FROM TABLE
> will return two times the same value.
> This doesn't hold true for TIMESTAMPADD and TIMESTAMPDIFF, which are not available in
the "regular" syntax according to:
> http://db.apache.org/derby/docs/10.8/ref/rrefsqlj29026.html
> It would probably be a lot simpler for most users, not to get used to the {fn ...} syntax.
