This may be really simple but i have been looking at it to long and my head is about to expode. I am trying to do a left join on a category table to return the category name instead of the MyCategoryID (foriegn key) This is my code:

$sqlQuery = new SQLQuery();
      $sqlQuery->select = array(
       'v.ID AS vID',
       'v.vTitle AS vTitle',
       'v.vRef As vRef',
       'v.vPosition As vPosition',
       'v.vLocation As vLocation',
       'v.vSalary As vSalary',
       'v.vDescription As vDescription',
       'vc.vCategory As Category'
      );
      $sqlQuery->from = array(" Vacancy v LEFT JOIN VacancyCategory vc ON v.MyCategoryID = vc.ID");
      
      // $sqlQuery->where = "";
      // $sqlQuery->having = "";
      $sqlQuery->orderby = "vID DESC";
      // $sqlQuery->limit = "";
      // $sqlQuery->distinct = true;
      
      // get the raw SQL
      $rawSQL = $sqlQuery->sql();
      
      // execute and return a Query-object
      $result = $sqlQuery->execute();

if i return it, i get:

MySQLQuery::__set_state(array( 'database' => MySQLDatabase::__set_state(array( 'dbConn' => NULL, 'active' => true, 'database' => 'csITA', 'mysqlVersion' => NULL, 'tableList' => NULL, 'fieldList' => NULL, 'indexList' => NULL, 'schemaUpdateTransaction' => NULL, 'extension_instances' => array ( ), 'class' => 'MySQLDatabase', )), 'handle' => NULL, 'currentRecord' => NULL, 'rowNum' => -1, 'extension_instances' => array ( ), 'class' => 'MySQLQuery', ))

DOH! I dont want that.

How do i convert the $result to a Dataobject that i can easily plonk onto the template?

Any help will be REALLY appreciated!!!

BumP :-(

Anyone please??? I have been ripping my hair out for 2 days on this.

I have been trying to work of the documentation but it isnt working for me. http://doc.silverstripe.com/doku.php?id=sqlquery#transforming_a_result_to_dataobjectset

My code is returning results on the Debug::show($results); :

   $sqlQuery = new SQLQuery();
      $sqlQuery->select = array(
       'v.ID AS ID',
       'v.vTitle AS vTitle',
       'v.vRef As vRef',
       'v.vPosition As vPosition',
       'v.vLocation As vLocation',
       'v.vSalary As vSalary',
       'v.vDescription As vDescription',
       'vc.vCategory As Category',
       /*"if(`Vacancy`.ClassName,`Vacancy`.ClassName, 'Vacancy') As RecordClassName"*/
      );
      $sqlQuery->from = array(" Vacancy v LEFT JOIN VacancyCategory vc ON v.MyCategoryID = vc.ID");
      
      // $sqlQuery->where = "";
      // $sqlQuery->having = "";
      $sqlQuery->orderby = "ID DESC";
      // $sqlQuery->limit = "";
      // $sqlQuery->distinct = true;
      
      // get the raw SQL
      $rawSQL = $sqlQuery->sql();
      
      // execute and return a Query-object
      $result = $sqlQuery->execute();
            
      $vacancies = new DataObjectSet();
         
      foreach($result as $row) {
      
       $vacancies->push($row);
      
      }
       
      Debug::show($vacancies);
      
      return $vacancies;

But the return $vacancies is returning a blank page!!!!!

The problem is that you weren't using buildDataObjectSet().

You don't necessary need to use buildDataObjectSet, but you will need to build ViewableData objects somehow. The simplest is ArrayData. ArrayData will turn a regular PHP map into a ViewableData object suitable for use in a template.

Change
$vacancies->push($row);

to
$vacancies->push(new ArrayData($row));
