Php 带有IF条件的SELECT语句

我有一个表，它有列

menu_id , parent_id, controller , action , action_edit , action_view , 


select * from test where  
( action like 'my_action.php' or 
action_edit like '%my_action.php%' or 
action_view like '%my_action.php%'
) AND parent_id !=0 ORDER BY `controller` ASC 

当action或action\u view或action\u edit为home.php->我想省略父\u id=0

我试着用

和IFaction='home.php'或action\u view='home.php'或action\u edit='home.php'，家长=0，而不是和父\u id=0但它给了我一个令牌不匹配错误

但是不工作，提前谢谢你：

怎么样：

select * from test where  
(( action like 'my_action.php' or 
action_edit like '%my_action.php%' or 
action_view like '%my_action.php%'
)) AND (parent_id !=0)) 
ORDER BY `controller` ASC

试着这样做：

select *
from test
where  'home.php' not in (action, action_view, action_edit) or parent_id <> 0) and
       (action like 'my_action.php' or action_edit like '%my_action.php%' or 
        action_view like '%my_action.php%'
       )

也许你想要这个

select * from test where  
(( action like 'my_action.php' or 
   action_edit like '%my_action.php%' or 
   action_view like '%my_action.php%'
 ) AND parent_id !=0)
OR 
( action='home.php' OR 
  action_view='home.php' OR 
  action_edit='home.php') 
ORDER BY `controller` ASC

试试这个：

SELECT * FROM test
  WHERE NOT EXISTS ((SELECT A.* FROM test A)
                   JOIN (SELECT B.* FROM test B WHERE 
                         B.action like 'my_action.php'
                         OR B.action_edit like '%my_action.php%'
                         OR B.action_view like '%my_action.php%')
                   ON A.parent_id !=0)
ORDER BY `controller` ASC

嗨，我终于有办法了

select * from test where  
( action like 'my_action.php' or 
action_edit like '%my_action.php%' or 
action_view like '%my_action.php%'
) AND parent_id !=0 ORDER BY `controller` ASC 

而不是家长id=0我用过

和IFaction='home.php'或action\u view='home.php'或action\u edit='home.php'，parent=0，parent=0

现在开始工作了，谢谢你们的帮助。我发布了我的答案，因为我认为这将有助于解决类似问题的未来用户：

parent\u id=只有当action或action\u edit或action\u view为home.phpHi时，才应执行0行。您的代码工作：，但问题是action，action\u edit或action\u view可以为home.php，我要做的是在action为home.php时忽略父\u id 0，因为homep.hp的parant\u id=0，当我执行此查询时，当action为home.php时，结果为空：/action变量可以为NULL吗？action\u view和action\u edit可以为NULL，action不能为NULL

select * from test where  
( action like 'my_action.php' or 
action_edit like '%my_action.php%' or 
action_view like '%my_action.php%'
) AND parent_id !=0 ORDER BY `controller` ASC
