    <p>You should use <code>ResultSet#getLong()</code> instead. If in vain, try <code>ResultSet#getRowId()</code> and eventually cast it to <code>oracle.sql.ROWID</code>. If the returned hex string is actually the ID in hexadecimal flavor, then you can try converting it to decimal by <code>Long#valueOf()</code> or <code>Integer#valueOf()</code>.</p> <pre><code>Long id = Long.valueOf(hexId, 16); </code></pre> <p>That said, Oracle's JDBC driver didn't support <code>ResultSet#getGeneratedKeys()</code> for a long time and is still somewhat troublesome with it. If you can't get that right, then you need to execute a <code>SELECT CURRVAL(sequencename)</code> on the same statement as you did the <code>insert</code>, or a new statement inside the same transaction, if it was a <code>PreparedStatement</code>. Basic example:</p> <pre><code>public void create(User user) throws SQLException { Connection connection = null; PreparedStatement preparedStatement = null; Statement statement = null; ResultSet generatedKeys = null; try { connection = daoFactory.getConnection(); preparedStatement = connection.prepareStatement(SQL_INSERT); preparedStatement.setValue(1, user.getName()); // Set more values here. int affectedRows = preparedStatement.executeUpdate(); if (affectedRows == 0) { throw new SQLException("Creating user failed, no rows affected."); } statement = connection.createStatement(); generatedKeys = statement.executeQuery(SQL_CURRVAL); if (generatedKeys.next()) { user.setId(generatedKeys.getLong(1)); } else { throw new SQLException("Creating user failed, no generated key obtained."); } } finally { close(generatedKeys); close(statement); close(preparedStatement); close(connection); } } </code></pre> <p>Oh, from your code example, the following line</p> <pre><code>stmt.RETURN_GENERATED_KEYS; </code></pre> <p>is entirely superfluous. Remove it. </p> <p>You can find <a href="https://stackoverflow.com/questions/1915166/jdbc-how-can-we-get-inserted-record-id-in-java/1915197#1915197">here</a> another example which I posted before about getting the generated keys, it uses the normal <code>getGeneratedKeys()</code> approach.</p>

    1. COI tried the ResultSet#getLong(), it didn't work. Error returned was "Invalid column type: getLong not implemented for class oracle.jdbc.driver.T4CRowidAccessor" Am going to try your second suggestion.

    3. COThe following: oracle.sql.ROWID rid = rs.getObject(1); ID = rid.stringValue(); ID contains a hexadecimal value which is exactly I was getting before with the rs.getString(1); Will try your last suggestion.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
