A java.sql.PreparedStatement instance for adding delete operations to the download.

• DownloadTableData interface
• Direct row handling

In the following example, the setDownloadDeletes method uses the DownloadTableData.getDeletePreparedStatement to obtain a prepared statement for rows you want to delete. The java.sql.PreparedStatement.setInt method sets the primary key values for rows you want to delete in the remote database and the java.sql.PreparedStatement.executeUpdate method sets the row values in the download.

void setDownloadDeletes(DownloadTableData td) { 
    java.sql.PreparedStatement delete_ps = td.getDeletePreparedStatement();
    // This is the same as executing the following SQL statement:
    // DELETE FROM remoteOrders  where pk=2300;
    delete_ps.setInt(1, 2300); 
    delete_ps.executeUpdate();
    delete_ps.close();
 }
