IncorrectResultSetColumnCountException: Incorrect column count: expected 1, actual 38

Question

I am using JdbcTemplate to retrieve a Bean from the db. Here is my method:

public List  getTrackerData() {
    return List         


        

Answer 1

Implementing Bean RowMapper Interface and maprow function solve this problem

public class Mmitrackerv3LivedataMapper implements RowMapper {

@Override
public Mmitrackerv3Livedata mapRow(ResultSet rs, int rowNum)
        throws SQLException {
}

And Now I have Change In JDBC Template

 List live = jdbcTemplate.query("select * from mmitrackerv3_livedata mlive " + 
 "join mmitrackerv3_device mdevice on mlive.accountid = mdevice.accountid where mlive.accountid = " +
     aid, new Mmitrackerv3LivedataMapper());
