Expoting Dataset to a xml file giving error in DBunit

Hi all i'm working using dbunit. I'm trying to export datset of db into a xml file.

import java.sql.Connection;
import java.sql.DriverManager;
import org.dbunit.database.DatabaseConnection;
import org.dbunit.database.IDatabaseConnection;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.xml.FlatXmlDataSet;
import java.io.FileOutputStream;

public class DatabaseExport

{
    public static void main(String[] args) throws Exception
    {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());
        Connection jdbcConnection = DriverManager.getConnection("jdbc:sqlserver://172.26.37.113:1433;DatabaseName=def_config","sqladmin_","halloween$2004");
        IDatabaseConnection connection = new DatabaseConnection( jdbcConnection );
       // full database export
        IDataSet fullDataSet = connection.createDataSet();
        FlatXmlDataSet.write(fullDataSet, new FileOutputStream("full.xml"));

    }
}

But it gives an error like this:

Exception in thread "main" org.dbunit.dataset.DataSetException: com.microsoft.sqlserver.jdbc.SQLServerException: Incorrect syntax near the keyword 'user'.

My guess is that you have a table called user in your database. But user is a reserved keyword in MSSQL. DBUnit creates some query like:

SELECT * FROM user;

But this creates the error you are seeing. Instead DBUnit has to create a query like:

SELECT * from [user];

I think you could fix this using the Escape pattern configuration setting of DBUnit. I didn't try this myself but something like this should work:

connection.getConfig().setProperty(DatabaseConfig.PROPERTY_ESCAPE_PATTERN , "[?]");

I hope this helps! :)

Thanks for above solution. That is the actual solution.

import java.sql.Connection;
import java.sql.DriverManager;
import org.dbunit.database.DatabaseConfig;
import org.dbunit.database.DatabaseConnection;
import org.dbunit.database.IDatabaseConnection;
import org.dbunit.dataset.IDataSet;
import org.dbunit.dataset.xml.FlatXmlDataSet;
import java.io.FileOutputStream;

public class DatabaseExport
{
    public static void main(String[] args) throws Exception
    {
        Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
        DriverManager.registerDriver(new com.microsoft.sqlserver.jdbc.SQLServerDriver());
        Connection jdbcConnection = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=def_config","user","passwd$2004");
        IDatabaseConnection connection = new DatabaseConnection( jdbcConnection );
        connection.getConfig().setProperty(DatabaseConfig.PROPERTY_ESCAPE_PATTERN , "[?]");
        // full database export
        IDataSet fullDataSet = connection.createDataSet();
        FlatXmlDataSet.write(fullDataSet, new FileOutputStream("C:/full.xml"));
    }
}

If you want to export the dataset usnig ant we can do like this

<dbunit driver="com.microsoft.sqlserver.jdbc.SQLServerDriver" url="jdbc:sqlserver://localhost:1433;DatabaseName=config1" userid="user" password="passwd$2004" escapePattern="[?]" datatypeFactory="org.dbunit.ext.mssql.MsSqlDataTypeFactory"> <compare src="C:/export.xml"/> </dbunit>
