public static void main(String[] args) throws Exception {
// database connection

Connection jdbcConnection = DriverManager.getConnection(

// partial database export

partialDataSet.addTable("FOO","SELECT * FROM TABLE WHERE COL='VALUE'");
partialDataSet.addTable("BAR");
FlatXmlDataSet.write(partialDataSet,new FileOutputStream("partial.xml"));

IDataSet fullDataSet = connection.createDataSet();
FlatXmlDataSet.write(fullDataSet,new FileOutputStream("full.xml"));
// dependent tables database export: export table X and all tables that
// have a PK which is a FK on X,in the right order for insertion
String[] depTableNames =
TablesDependencyHelper.getAllDependentTables( connection,"X" );
IDataSet depDataSet = connection.createDataSet( depTableNames );
FlatXmlDataSet.write(depDataSet,new FileOutputStream("dependents.xml"));
