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 Id, OfficeId INTO [csv://c:/Departments.txt] FROM [Departments] WHERE Id = '1668776136772254'");
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 [Departments] IN 'csv://filename=c:/Departments.csv;delimiter=tab' FROM [Departments] WHERE Id = '1668776136772254'");
System.out.println(stat.getUpdateCount()+" rows affected");
