选择。。在Mysql中选择

我正在尝试为mysql

（搜索模块）

编写一个查询，由于要在同一个表中执行select操作，我遇到了一些困难

我的问题是：

(SELECT * FROM user WHERE `user_name` like '%TOM%' OR `user_name` like '%AN%' 
and `login_datetime` BETWEEN '2013-01-01 00:00:00' and '2013-02-31 23:59:59')
    OR
(SELECT * FROM user WHERE `user_name` like '%PHP%' OR `user_name` like '%BA%' 
and `login_datetime` BETWEEN '2013-02-01 00:00:00' and '2013-03-31 23:59:59')
    AND
(SELECT * FROM user WHERE `user_name` like '%SUN%' OR `user_name` like '%MOON%' 
and `login_datetime` BETWEEN '2013-03-01 00:00:00' and '2013-04-31 23:59:59') 
    NAND
(SELECT * FROM user WHERE `user_name` like '%RAJ%' OR `user_name` like '%MUTH%' 
and `login_datetime` BETWEEN '2013-04-01 00:00:00' and '2013-06-31 23:59:59') 
    NOR
 (SELECT * FROM user WHERE `user_name` like '%BAG%' OR `user_name` like '%LAP%'
 and `login_datetime` BETWEEN '2013-05-01 00:00:00' and '2013-07-31 23:59:59')

上述查询是我的场景。。在无法更改的地方，我尝试为此编写一个查询

注:

上述查询在单个表中执行

OR、NAND、NOR和操作可根据情况相互更改

这取决于用户，他需要如何搜索

我尝试了很多方法来实现逻辑，但我在所有阶段都面临问题

检查我的尝试：

在SQL中，可以按如下方式执行NAND和NOR操作：

只需根据需要编辑以下查询

SELECT * FROM user WHERE 
(`user_name` like '%TOM%' OR `user_name` like '%AN%' and `login_datetime` BETWEEN '2013-01-01 00:00:00' and '2013-02-31 23:59:59') OR
NOT ( --NOR
   (`user_name` like '%PHP%' OR `user_name` like '%BA%' and `login_datetime` BETWEEN '2013-02-01 00:00:00' and '2013-03-31 23:59:59') OR
   (`user_name` like '%SUN%' OR `user_name` like '%MOON%' and `login_datetime` BETWEEN '2013-03-01 00:00:00' and '2013-04-31 23:59:59')
) OR
NOT ( --NAND
   (`user_name` like '%RAJ%' OR `user_name` like '%MUTH%' and `login_datetime` BETWEEN '2013-04-01 00:00:00' and '2013-06-31 23:59:59') AND
   (`user_name` like '%BAG%' OR `user_name` like '%LAP%' and `login_datetime` BETWEEN '2013-05-01 00:00:00' and '2013-07-31 23:59:59')
)

在上面的示例中，如果第一个括号之间的条件为true或（第二个条件或第三个条件）或（第四个条件和第五个条件），则返回所有记录

注意：条件是指括号之间的子句。

NAND和NOR操作链接是我之前的问题，我可以在哪里实现操作，但当它涉及多个查询时，它不起作用……你能帮我将此MySQL转换为条令吗。。结构。
