import java.sql.ResultSet;
import java.sql.SQLException;

Used with SqlQuery to process potentially large queries reading directly from the JDBC ResultSet.

This provides a low level option that reads directly from the JDBC ResultSet.


 String sql = "select id, name, status from o_customer order by name desc";
 DB.sqlQuery(sql)
   .findEachRow((resultSet, rowNum) -> {
     // read directly from ResultSet
     long id = resultSet.getLong(1);
     String name = resultSet.getString(2);
     // do something interesting with the data
   });
