Re: [fw-db] Problem with JOIN

Hi Carlos,

The third parameter to join() accepts an array of columns to return for that table.

Since you are passing in an empty array, it is performing the join but not selecting any of the values. Try this and it should work:

->join(array('debe' => 'dirempresasbragaempresas'), 'debe.ID=sa.DirEmpresasBragaEmpresasID', array('Descricao'))

Hi,

I want to obtain a field from table 'dirempresasbragaempresas'. So:

$empresa = new Empresa();

$this->view->rows = $empresa->fetchAll($empresa->select()->setIntegrityCheck(false)

->join(array('sae' => 'sectoractividade_empresa'), 'sae.EmpresaNIPC=empresa.NIPC', array())

->join(array('sa' => 'sectoractividade'), 'sa.CAE=sae.SectorActividadeCAE', array())

->join(array('debe' => 'dirempresasbragaempresas'), 'debe.ID=sa.DirEmpresasBragaEmpresasID', array())

->where('empresa.Estado = ?', 'A')

->order('rand()')->limit(5, 0));

When i do:

foreach ($this->rows as $Row){

{$Row->Nome}

}

I can get the value from the field 'Nome' that came from table 'empresa'.

When i do:

foreach ($this->rows as $Row){

{$Row->Descricao}

} That is a field from table 'dirempresasbragaempresas', i have the next error:

Fatal error: Uncaught exception 'Zend_Db_Table_Row_Exception' with message 'Specified column "Descricao" is not in the row' in /Applications/MAMP/htdocs/BragaDigital/library/Zend/Db/Table/Row/Abstract.php:182

Thanks by helping me!!
