Robert Stupp updated CASSANDRA-7812:
------------------------------------
Attachment: 7812.txt
> DROP FUNCTION drops all function with a given name
> --------------------------------------------------
>
> Key: CASSANDRA-7812
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7812
> Project: Cassandra

>
> We support multiple overloads of a given function name, so that you can
> define:
> {noformat}
> CREATE FUNCTION div(int a, int b) RETURNS int 'myDivOnIntegerFct';
> CREATE FUNCTION div(double a, double b) RETURNS double 'myDivOnDoubleFct';
> {noformat}
> In other words, a function is uniquely identified by it's name *and* it's
> argument types.
> But the {{DROP FUNCTION}} syntax currently only take a function name and if
> there is multiple overload for that name, drop all of them without any way to
> drop one without the other.
> So we should probably allow to optionally pass the type arguments to DROP to
> select a specific overloading, something like:
> {noformat}
> DROP FUNCTION div(double, double);
> {noformat}
> Also, and while that's probably debatable, I'd also suggest to change the
> behavior of:
> {noformat}
> DROP FUNCTION div;
> {noformat}
> to complain if the there is multiple overload of the {{div}} method instead
> of dropping all overload as it feels somewhat foot-shooting otherwise.
