    <p>Is hibernatetemplate's <code>bulkUpdate</code> actually doing a <code>bulkUpdate</code>? I looked at the code, and it doesn't seem to be doing <code>bulkUpdate</code>. Or maybe am I missing something?</p> <pre><code>public int bulkUpdate(final String queryString, final Object... values) throws DataAccessException { return executeWithNativeSession(new HibernateCallback&lt;Integer&gt;() { public Integer doInHibernate(Session session) throws HibernateException { Query queryObject = session.createQuery(queryString); prepareQuery(queryObject); if (values != null) { for (int i = 0; i &lt; values.length; i++) { queryObject.setParameter(i, values[i]); } } return queryObject.executeUpdate(); } }); } </code></pre> <p>whereas <code>JdbcTemplate batchUpdate</code> (looks like) is doing a <code>batchUpdate</code></p> <pre><code>public int[] batchUpdate(final String[] sql) throws DataAccessException { Assert.notEmpty(sql, "SQL array must not be empty"); if (logger.isDebugEnabled()) { logger.debug("Executing SQL batch update of " + sql.length + " statements"); } class BatchUpdateStatementCallback implements StatementCallback&lt;int[]&gt;, SqlProvider { private String currSql; public int[] doInStatement(Statement stmt) throws SQLException, DataAccessException { int[] rowsAffected = new int[sql.length]; if (JdbcUtils.supportsBatchUpdates(stmt.getConnection())) { for (String sqlStmt : sql) { this.currSql = sqlStmt; stmt.addBatch(sqlStmt); } rowsAffected = stmt.executeBatch(); } else { for (int i = 0; i &lt; sql.length; i++) { this.currSql = sql[i]; if (!stmt.execute(sql[i])) { rowsAffected[i] = stmt.getUpdateCount(); } else { throw new InvalidDataAccessApiUsageException("Invalid batch SQL statement: " + sql[i]); } } } return rowsAffected; } public String getSql() { return this.currSql; } } return execute(new BatchUpdateStatementCallback()); } </code></pre>

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.
