 see also at http://dbunit.sourceforge.net/faq.html#extractHow to extract a flat XML dataset from my database?

The following sample demonstrates how you can export one or many tables from a database to an flat XML dataset file.

public class DatabaseExportSample { public static void main(String[] args) throws Exception { // database connection Class driverClass = Class.forName("org.hsqldb.jdbcDriver"); Connection jdbcConnection = DriverManager.getConnection( "jdbc:hsqldb:sample", "sa", ""); IDatabaseConnection connection = new DatabaseConnection(jdbcConnection); // partial database export QueryDataSet partialDataSet = new QueryDataSet(connection); partialDataSet.addTable("FOO", "SELECT * FROM TABLE WHERE COL='VALUE'"); partialDataSet.addTable("BAR"); FlatXmlDataSet.write(partialDataSet, new FileOutputStream("partial.xml")); // full database export 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")); } }
