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 Worker_Reference_WID, Legal_Name_Last_Name INTO [csv://c:/[CData].[Human_Resources].Workers.txt] FROM [[CData].[Human_Resources].Workers] WHERE Legal_Name_Last_Name = 'Morgan'");
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 [[CData].[Human_Resources].Workers] IN 'csv://filename=c:/[CData].[Human_Resources].Workers.csv;delimiter=tab' FROM [[CData].[Human_Resources].Workers] WHERE Legal_Name_Last_Name = 'Morgan'");
System.out.println(stat.getUpdateCount()+" rows affected");
