    <p>You can do the following for e.g. using iBatis (I'm using iBatis version 2.3.4 so this example is based on that). Creating a batch of statements can improve performance. It is also important to note to wrap the batch in a single transaction as if it is not wrapped then a new transaction will be started for each statement (performance can be an issue depending on batch size I believe). </p> <p>See example below. You will notice that the start of the batch <code>startBatch()</code> is only started after the parent record is updated or inserted. This is because database generated keys will not be generated until you have called the <code>executeBatch()</code>. This means if you are using <code>selectKey</code> to update your objects with the generated keys they will return null. This is why the creation/update of the Parent record is before the <code>startBatch()</code> statement. Hope this helps as an example for you.</p> <pre><code>try { sqlMap.startTransaction(); if (parent.getId == null) { sqlMap.insert("createParent", parent); } else { sqlMap.update("updateParent", parent); } sqlMap.startBatch(); for (final Child exapleChild: parent.getChildren()) { exapleChild.setParentId(parent.getId); sqlMap.insert("createChildForParent", objectReference1); } sqlMap.executeBatch(); sqlMap.commitTransaction(); } catch (final SQLException e) { throw new XXXException(e); } finally { try { sqlMap.endTransaction(); } catch (SQLException e) { throw new XXXException(e); } } </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.
