26. CONSULTAR select * from tabela where nome = 'Jean Nascimento' $filter = array( &quot;nome&quot; => &quot;Jean Nascimento&quot; ); $cursor = $collection->find($filter); foreach ($cursor as $arr) { echo $arr[&quot;nome&quot;]. &quot; - &quot; . $arr[&quot;_id&quot;] . &quot;<br />&quot;; }

27. CONSULTAR select * from tabela where nome LIKE 'J___ Nascimento' $filter = array( &quot;nome&quot; => new MongoRegex('/^J[a-Z]{3} Nascimento/i' ); select * from tabela where nome LIKE '%Nasc%' $filter = array( 'title' => new MongoRegex('/.Nasc./i') );

28. ALTERAR update tarefas set Tarefa='Terminar artigo' where Usuario='suissa' $db->collection->update( array('Usuario'=> 'suissa'), array('$set' => array('Tarefa' => 'Terminar artigo')) ); update users set a=a+2 where b='q' $db->users->update(array(&quot;b&quot; => &quot;q&quot;), array('$inc => array(&quot;a&quot; => 2)));

30. EXPLAIN EXPLAIN SELECT * FROM users WHERE z=3 $db->users->find(array(&quot;z&quot; => 3))->explain()

35. Talk is cheap. Show me the code .

36. $nome_banco = ‘prioridades’; $nome_collection = ‘tarefas’; $this->conexao = new Mongo(); $this->db = $this->conexao->$nome_banco; $this->collection = $this->db->$nome_collection;

37. function inserir(){ $this->query = array( ‘ UsuarioID’ => $this->UsuarioID, ‘ Usuario’ => $this->Usuario, ‘ Tarefa’ => $this->Tarefa, ‘ Tipo’ => $this->Tipo,//Obrigatório, idéia, outro ‘ Prioridade’ => $this->Prioridade); $this->collection->insert($this->query); }

38. function excluir(){ $this->mongo_id = new MongoID($this->_id); $this->collection->remove(array(‘_id’ => $this->mongo_id)); }

39. function mudar_tarefa(){ $this->mongo_id = new MongoID($this->_id); $this->collection->update(array(‘_id’ => $this->mongo_id), array(‘$set’ => array(‘Tarefa’ => $this->Tarefa)), false); }

40. function mudar_tarefa(){ $this->mongo_id = new MongoID($this->_id); $this->collection->update(array(‘_id’ => $this->mongo_id), array(‘$set’ => array(‘Tarefa’ => $this->Tarefa)), false); }

41. function mudar_prioridade(){ $this->mongo_id = new MongoID($this->_id); if($this->modo==’up’){ $this->collection->update( array(‘_id’ => $this->mongo_id), array(‘$inc’ => array(‘Prioridade’ => 1)), false ); } elseif($this->modo==’down’){ $this->collection->update( array(‘_id’ => $this->mongo_id), array(‘$inc’ => array(‘Prioridade’ => -1)), false ); } }
