You can use the SELECT INTO statement to export formatted data to a file.

Data Export with an SQL Query

The following query exports data into a file formatted in comma-separated values (CSV):

boolean ret = stat.execute("SELECT DslAddressDatabase, Type INTO [csv://c:/Tables.txt] FROM [Tables] WHERE Name = 'FactProductInventory'");
System.out.println(stat.getUpdateCount()+" rows affected");

You can specify other file formats in the URI. The following example exports tab-separated values:

Statement stat = conn.createStatement();
boolean ret = stat.execute("SELECT * INTO [Tables] IN 'csv://filename=c:/Tables.csv;delimiter=tab' FROM [Tables] WHERE Name = 'FactProductInventory'");
System.out.println(stat.getUpdateCount()+" rows affected");
