Question

我有两个表，(1)表客户端和(2)表客户端操作。
这是我的样本表：

表客户端：

id_clients | name | id_user_created | id_user_owner
    1        alfa         4                0
    2        beta         4                0
    3       charlie       5                0

表客户端操作：

id_clients_action |       date_action   | id_clients | id_user_created | id_user_owner
         1           2015-09-04 17:09:37        1              4              0
         2           2015-09-05 18:19:07        1              4              0

然后，在表单中，我有两个输入参数，从日期到日期。
这些是我的条件：

Condition-1 : 
-id_user_created = 4
-from date = 2015-09-01 00:00:00
-end date = 2015-09-03 00:00:00

我想要一个这样的结果：

 id_clients | name | date 
     1        alfa   null
     2        beta   null

下一个条件：

Condition-2 : 
-id_user_created = 4
-from date = 2015-09-01 00:00:00
-end date = 2015-09-22 00:00:00

我想要一个这样的结果：

id_clients | name | date 
    1        alfa   2015-09-04 17:09:37
    1        alfa   2015-09-05 18:19:07
    2        beta   null

以下是我的查询，但我仍然有一个真实的日期，我希望得到我的条件的结果。请给我一个真正的问题。

select B.id_clients, B.id_user_created, B.name, A.date_action as  lastActionDate
from clients_action as A
right join clients as B on A.id_clients=B.id_clients
where 
B.id_clients in 
(
     select id_clients 
     from clients_action where 
     date_action between '2015-09-01 00:00:00' and '2015-09-03 00:00:00' and id_user_owner = '0'
)
or
B.id_clients in 
(
    select id_clients 
    from clients 
     where 
    id_user_created = '4' and id_user_owner = '0'
)
