Can't get all Imported Keys from dmd

От

Дата:
The following code SHOULD (according to the JDK1.4 docs) get all the
primary keys related to a table's foreign keys, if I read the docs
right. But I get back a ResultSet only containing one (1) key, not two,
as in my table.

Can someone explain this to me? Why won't it return all the keys in the
ResultSet?

Thanks!

ResultSet fkpk = dmd.getImportedKeys("", "", "login");

while (fkpk.next())
{
    System.out.println("PK: " + fkpk.getString("PKTABLE_NAME"));
    System.out.println("\t" + fkpk.getString("PKCOLUMN_NAME"));
    System.out.println("FK: " + fkpk.getString("FKTABLE_NAME"));
    System.out.println("\t" + fkpk.getString("FKCOLUMN_NAME"));
}

System.out.println(" ");
**********************************
Table creation script:

drop table login;
drop sequence login_id_seq;

create table login(
    id            serial primary key,
    memberid        int references members(id),
    userid            varchar(15) not null,
    password        varchar(15) not null,
    verification        char(20),
    verifydatesent        date,
    verifydaterecd        date,
    accesslevel        int references accesslevels(id),
    remoteip        varchar(16),
    reminderquestion    varchar(80),
    reminderanswer        varchar(25)
);
create index idxloginid on login(id);
create index idxlogin_memberid on members(id);

Test results:

PK: accesslevels
        id
FK: login
        accesslevel

David,

Try the development driver, this has been fixed in the latest sources

The development driver for the jdbc? Or the odbc driver in the
postgresql release?

Thanks!
