SQL Active Record and aliases

Hello,

I'm trying to run a SQL Query with joins, and some fields share the same names in two different tables, but I need there status, my query works perfectly directly in MySQL, and to keep a record which column is from which table i'm creating an alias on it.

SELECT n.status as rds, i.status as installation FROM serveur as s join nas as n on n.id=s.nas_id join installation as i on i.id=s.installation_id WHERE s.id=447;

Normally the results look like this:

+---------+--------------+

| rds     | installation |

+---------+--------------+

| created | created         |

+---------+--------------+

But in my scriptable task, I see this:

[2016-08-30 13:00:19.371] [I] SELECT n.status as rds, i.status as installation FROM serveur as s join nas as n on n.id=s.nas_id join installation as i on i.id=s.installation_id WHERE s.id=447;

I have no clue which status is this and then the rest of my code doesn't work.

Here's my complete scriptable task:

var result = null;

var query = 'SELECT n.status as rds, i.status as installation ' +

            'FROM serveur as s join nas as n on n.id=s.nas_id join installation as i on i.id=s.installation_id ' +

            'WHERE s.id=' + vmid + ';';

 

 

System.log(query);

var response = database.readCustomQuery(query);

System.log(response);

 

 

for (var i = 0; i < response.length; i += 1) {

  if (response != null && response.lenght == 1) {

  nstatus = response[i].getProperty("rds"); 

  istatus = response[i].getProperty("installation"); 

  break;

  }

}

 

 

if (result) {

  nstatus = result.toString();

  istatus = result.toString();

 

  System.log('Result: ' + nstatus);

  System.log('Result: ' + istatus);

} else {

  throw 'Couldn\'t get a response from the database';

}
