>                 Key: DERBY-6587
>                 URL: https://issues.apache.org/jira/browse/DERBY-6587
>             Project: Derby
>          Issue Type: Bug
>          Components: Store
>    Affects Versions: 10.10.2.0
>         Environment: Windows 7, Java 7
>            Reporter: Pascal GrĂ¼n
>            Assignee: Myrna van Lunteren
>         Attachments: DERBY-6587_tst.diff, RIBulkChecker.diff, TABLE1_T.csv, TABLE2_T.csv,

> There is a problem in org.apache.derby.impl.sql.execute.RIBulkChecker:
> result = fkCol.compare(refCol);
>             if (result == 1)
>             {
>                 return GREATER_THAN;
>             }
>             else if (result == -1)
>             {
>                 return LESS_THAN;
>             }
> where the JavaDoc for "compare" explicitly states that one must not use 1 or -1 to check
the return value.
> The problem can be reproduced when creating a table with two fields, "UUID_FIELD char
(16) for bit data" and "NUM_FIELD integer", then having a foreign key to these two fields
and then using the bulk import, i.e. "CALL SYSCS_UTIL.SYSCS_IMPORT_TABLE ..."
