>                 Key: DERBY-3300
>                 URL: https://issues.apache.org/jira/browse/DERBY-3300
>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.3.1.4, 10.3.2.1
>            Reporter: Daniel John Debrunner
>            Priority: Minor
>
> Since CREATE INDEX statement succeeds the index should be created, the warning is useful
but doesn't imply the index was not created.
> Derby allows a single physical index to support multiple logical indexes so allowing
the index to be created should be fine.
> ij> create table t(i int);
> 0 rows inserted/updated/deleted
> ij> create index ti1 on t(i);
> 0 rows inserted/updated/deleted
> ij> create index ti2 on t(i);
> 0 rows inserted/updated/deleted
> WARNING 01504: The new index is a duplicate of an existing index: TI1.
> ij> drop index ti2;
> ERROR 42X65: Index 'TI2' does not exist.
