I have two tables.
Table invitations
Columns:
id email created_at
Table orders
Columns:
id amount email created_at
i need to create a DQL to select all the fields from invitations table and left join with count of all the record in orders table with on email
NOTE I need to view the results so I need to paginate the results and there is no relation between the two tables
Create the DQL query:
$q = Doctrine_Query::create()
->select('i.*')
->from('invitations i')
->leftJoin('i.orders o ON i.email=o.email')
;
You may add more conditions:
->having('COUNT(email) > 10')
->groupBy('i.email')
->orderBy('i.email ASC');
Print the result SQL query to check for errors:
echo $q->getSqlQuery();
Execute the DQL query:
$vrows = $q->execute(array(), Doctrine_Core::HYDRATE_ARRAY); //For speed use Hydrate_Array, read the documentation about hydrating methods. If not specified you will get a list of records objects.
Another way would be like ilSavo and Michal said, create your own query or write in your schema the relation between those two tables.
A third way would be to directly send the SQL raw query to the database, without using the ORM Doctrine:
$oConnection = Doctrine_Manager::getInstance()->getConnectionForComponent($sModuleName);
$vrecords = $oCurrentConnection->fetchAssoc($sSQLquery);
In order to paginate your results take a look here.
Remember to use try and catch in order to get exceptions.
