[ http://jira.qos.ch/browse/LBCORE-15?page=com.atlassian.jira.plugin.system.is... ] Søren Boisen commented on LBCORE-15: ------------------------------------ It's important to note that the original suggestion, to use prepareStatement(String, int) will not work. In this case Oracle will return the ROWID of the inserted row instead of the EVENT_ID column. As John Gibson wrote, prepareStatement(String, String[]) should be used instead, specifying EVENT_ID as the name of the column to be returned. For other people that cannot wait for this bug to be fixed, a workaround is to write your own class extending DBAppender: public class OracleDBAppender extends DBAppender { @Override public void append (LoggingEvent eventObject) { Connection connection = null; try { connection = connectionSource.getConnection(); connection.setAutoCommit(false); PreparedStatement insertStatement = connection.prepareStatement( getInsertSQL(), new String[] {"EVENT_ID"}); subAppend(eventObject, connection, insertStatement); // we no longer need the insertStatement if (insertStatement != null) { insertStatement.close(); insertStatement = null; } connection.commit(); } catch (Throwable sqle) { addError("problem appending event", sqle); } finally { DBHelper.closeConnection(connection); } } } Then in your configuration file simply declare the class of the appender to attach as your new OracleDBAppender class.

Problems getting autogenerated Keys in Oracle with Oracle JDBC 10.2.03 ----------------------------------------------------------------------

Key: LBCORE-15 URL: http://jira.qos.ch/browse/LBCORE-15 Project: logback-core Issue Type: Bug Components: Appender Affects Versions: unspecified Environment: Operating System: Windows Platform: PC Reporter: Klaus Unger Assignee: Logback dev list Priority: Blocker

I've encountered troubles logging StackTrace/MDC entries with die DBAppender on our plattform! We are using Oracle 9.2.0.6.0 on a Solaris Box with Oracle JDBC Driver 10.2.0.3! I've debugged the processing of LogMessages into DBAppenderBase.append()! There I found a call "con.prepareStatement(getInsertSQL())" which is followed by a call "subAppend(...)" As far as I understand Oracle Drivers return generatedKeys only, if you use the right prepareStatement() methods, which is in my understanding the following: PreparedStatement prepareStatement(String sql, int autoGeneratedKeys) throws SQLException @see http://java.sun.com/j2se/1.5.0/docs/api/java/sql/Connection.html#prepareStat...) which is available since JDK 1.4
