Rick Hillegas commented on DERBY-6763:
--------------------------------------
Hi Mark,
For builtin functions, overloading is easy. For user-defined functions, Derby
supports varargs routines. The trailing (variable) arguments must all have the
same datatype.
Thanks,

> Allow users to specify TRANSLATE function
> -----------------------------------------
>
> Key: DERBY-6763
> URL: https://issues.apache.org/jira/browse/DERBY-6763
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 10.11.1.1
> Reporter: Mark Buyukisik
> Priority: Minor
>
> I was wondering if Derby could please allow users to specify a TRANSLATE
> function. It does not look like one exists but when I try to create one I am
> denied because TRANSLATE is a reserved word. Right now we are using Derby as
> an embedded database used for local development and DAO impl testing (DB2 is
> used for official testing and production) and would like to be able to
> specify this function so our SQL statements work against both Derby and DB2.
> Thanks,
> Mark
