while循环Python中的SQL查询

Question

嗨，我有尝试在运行良好的PHP这个查询和我做同样的事在Python

$select=mysql_query("SELECT DISTINCT A.entity_id AS entity_id ,A.email AS email,A.catquizid AS style_quiz_score ,A.catquizquesans AS style_quiz_answer,A.created_at AS date_joined,A.is_active AS is_active ,B.attribute_id AS attribute_id,B.value AS info FROM `customer_entity` AS A inner join `customer_entity_varchar` AS B on A.entity_id=B.entity_id WHERE B.`attribute_id` IN (1,2) limit 10",$conn); 

    $arr=array(); 

    while($result= mysql_fetch_assoc($select)) 
     { 
      if(!isset($arr[$result['entity_id']]['lastname'])){ 
       $arr[$result['entity_id']]['firstname'] = $result['info']; 
      } 
      $arr[$result['entity_id']]['lastname'] = $result['info']; 
      $arr[$result['entity_id']]["email"]=$result['email']; 
      $arr[$result['entity_id']]["style_quiz_score"]=$result['style_quiz_score']; 
      $arr[$result['entity_id']]["style_quiz_answer"]=$result['style_quiz_answer']; 
      $arr[$result['entity_id']]["date_joined"]=$result['date_joined']; 
      $arr[$result['entity_id']]["is_active"]=$result['is_active']; 

      $arr[$result['entity_id']]["username"]=normalize_str($result['email']); 
     } 

，并在Python我已经尝试过这种

def customer_migrate(request): 
    cursor = connections['migration'].cursor() 
    cursor.execute("SELECT DISTINCT A.entity_id AS entity_id ,A.email AS email,A.catquizid AS style_quiz_score ,A.catquizquesans AS style_quiz_answer,A.created_at AS date_joined,A.is_active AS is_active ,B.attribute_id AS attribute_id,B.value AS info FROM customer_entity AS A inner join customer_entity_varchar AS B on A.entity_id=B.entity_id WHERE B.attribute_id limit 4 ") 
    row = cursor.fetchall() 

如何使用while循环在Python查询，

Answer 1

使用fetchone（）或只是遍历光标：

row = cursor.fetchone() 
while row is not None: 
    print row 
    row = cursor.fetchone() 

或

for row in cursor: 
    print row
