Where clause conundrum：where「LIKE」one thing but not「like another」is failing？

您好我有這樣一個表結構：Where clause conundrum：where「LIKE」one thing but not「like another」is failing？

mysql>DESC file; 
file_id   
fullpathname

與記錄

file_id | fullpathname           
--------+------------------------------------------------------ 
     6 | /var/tmp/4x4 and 6x4/test/test3.txt 
     7 | /var/tmp/4x4 and 6x4/test/somefile 
     8 | /var/tmp/4x4 and 6x4/test   
     9 | /var/tmp/4x4 and 6x4/6x4_1.JPG  
    10 | /var/tmp/4x4 and 6x4/6x4_2.JPG  
    11 | /var/tmp/4x4 and 6x4/4x4_2.jpg  
    12 | /var/tmp/4x4 and 6x4/4x4_1.jpg  
    13 | /var/tmp/dir/4x4 and 6x4

和查詢需要是差不多就是下面我有（但它不工作）

SELECT * FROM file 
WHERE fullpathname LIKE '/var/tmp/4x4 and 6x4%' 
AND fullpathname NOT LIKE '/var/tmp/4x4 and 6x4/%/'

，但它不需要返回它需要的file_id 6和7，只需要選擇一個節點深的「路徑」。這是一個奇怪的人，但這樣的情況

它應該返回的是

file_id | fullpathname           
--------+------------------------------------------------------ 
     8 | /var/tmp/4x4 and 6x4/test   
     9 | /var/tmp/4x4 and 6x4/6x4_1.JPG  
    10 | /var/tmp/4x4 and 6x4/6x4_2.JPG  
    11 | /var/tmp/4x4 and 6x4/4x4_2.jpg  
    12 | /var/tmp/4x4 and 6x4/4x4_1.jpg  
    13 | /var/tmp/dir/4x4 and 6x4

'13 |/var/tmp/dir/4x4和6x4'不會被返回，因爲它不是'LIKE'/ var/tmp/4x4和6x4％'' – StuartLC

不可以，沒關係那是我忘記識別的另一個遺漏，這對我的需求沒問題，我不想要'13''6'或'7' – conners

試試這個：

SELECT * FROM file 
WHERE fullpathname LIKE '/var/tmp/4x4 and 6x4%' 
AND fullpathname NOT LIKE '/var/tmp/4x4 and 6x4/%/%'

是的，你說得對，當然，因爲隨後的字符串，當然 – conners
