What is the format of xml data set query String

bitisony

Hi all,

I want to create a new data set by using script.

I found a sample in the network.
But I do not understand the format of the xml data set query string.
As:

void buildDataSet(IReportContext reportContext) throws SemanticException
{
OdaDataSetHandle dsHandle =
reportContext.getDesignHandle().getElementFactory()
.newOdaDataSet("ds",
"org.eclipse.birt.report.data.oda.xml.dataSet");
dsHandle.setDataSource("reportDataSource");

String qry = "table0#-TNAME-#table0#:#[REPORT/RF-SUMMARY/OBJECT-SUMMARY/AP-RADIO-STATISTICS]#:#{time;String;}";
dsHandle.setQueryText(qry);
reportContext.getDesignHandle().getDataSets().add(dsHandle);
}

What is the meaning of "table0"?
And I want to query more attributes, how can I do that?

Thanks in advance for your help!
