Subject [jira] Updated: (DERBY-3404) EmbedResultSet.getString() returns wrong value after auto-commit with CLOSE_CURSORS_AT_COMMIT
Date Mon, 11 Feb 2008 15:20:08 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3404?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-3404:
--------------------------------------

    Derby Info: [Regression]

On 10.2.2.0 the repro prints Y, whereas on 10.3.1.4 it prints null.

Although I'm not sure the pre-10.3 behaviour is completely correct either (it should perhaps
have thrown an exception), at least the correct value is returned, so I'm marking this as
a regression.

>             Project: Derby
>          Issue Type: Bug
>    Affects Versions: 10.3.1.4, 10.3.2.1, 10.4.0.0
>            Reporter: Knut Anders Hatlen
>            Priority: Minor
>         Attachments: CloseOnCommit.java

> The following code prints "null" to the console with the embedded driver:
>         Statement s = c.createStatement(ResultSet.TYPE_FORWARD_ONLY,
>                                         ResultSet.CONCUR_READ_ONLY,
>                                         ResultSet.CLOSE_CURSORS_AT_COMMIT);
>         ResultSet rs = s.executeQuery("select * from sysibm.sysdummy1");
>         rs.next();
>         c.createStatement().executeQuery("values 1").close(); // causes auto-commit
>         System.out.println(rs.getString(1));
> The call to rs.getString() should perhaps have thrown SQLException, since the auto-commit
between next() and getString() should close the ResultSet when the holdability is CLOSE_CURSORS_AT_COMMIT,
I think. Anyway, the value stored in SYSIBM.SYSDUMMY1 is 'Y' and not NULL, so it should definitely
not return null.
