ColumnHints in ODA driver extenstion

cwagner

<p><span>Hello everybody,<br><br>
I'm working on an ODA driver extension for BIRT and I like to specifiy aliase for the resultset columns. It seems to be possible by using ColumnHints. Unfortunately I haven't found a useable sample or documentation how exactly to do this.<br><br>
I have found some information about it, but however it's not really clear to me:<br>
<a data-ipb='nomediaparse' href='http://developer.actuate.com/be/documentation/JAVADOCS/BIRT-4.4.1/org.eclipse.birt.doc.isv/model/api/index.html?org/eclipse/birt/report/model/api/elements/structures/ColumnHint.html'>http://developer.actuate.com/be/documentation/JAVADOCS/BIRT-4.4.1/org.eclipse.birt.doc.isv/model/api/index.html?org/eclipse/birt/report/model/api/elements/structures/ColumnHint.html</a><br&gt;
<a data-ipb='nomediaparse' href='http://www.programcreek.com/java-api-examples/index.php?api=org.eclipse.datatools.connectivity.oda.design.ResultSetDefinition'>http://www.programcreek.com/java-api-examples/index.php?api=org.eclipse.datatools.connectivity.oda.design.ResultSetDefinition</a><br><br&gt;
Could anybody help, please?<br>
Thanks.</span></p>

<p>If you look at the dataSetHandle, there's a columnHintsIterator.</p>

<p>You might look into that.</p>
<p> </p>
<p>You could also look at the source code for BIRT to see the other ODA's to see exactly how they've done aliases. </p>

<p>Let me know if you run into issues.</p>
