MySQL的：NOT LIKE

Question

我在我的分貝這些文字，

categories_posts 
categories_news 
posts_add 
news_add 

而且我不想categories選擇行，我用一個查詢這樣的事情，

SELECT * 
    FROM developer_configurations_cms 

    WHERE developer_configurations_cms.cat_id = '1' 
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%' 
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%' 

但它返回這兩個輸出以及...

categories_posts 
categories_news 

如何在我的查詢中忽略它們？

謝謝。

Answer 1

categories_posts和categories_news開始與子「categories_」，那麼就足夠了檢查developer_configurations_cms.cfg_name_unique是否以'categories'開頭，而不是檢查它是否包含給定的子字符串。將所有這些轉換成查詢：

SELECT * 
    FROM developer_configurations_cms 

    WHERE developer_configurations_cms.cat_id = '1' 
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%' 
    AND developer_configurations_cms.cfg_name_unique NOT LIKE 'categories%' 

Answer 2

我不知道爲什麼

cfg_name_unique NOT LIKE '%categories%' 

仍返回這兩個值，但也許它們排除在外明確：

SELECT * 
    FROM developer_configurations_cms 

    WHERE developer_configurations_cms.cat_id = '1' 
    AND developer_configurations_cms.cfg_variables LIKE '%parent_id=2%' 
    AND developer_configurations_cms.cfg_name_unique NOT LIKE '%categories%' 
    AND developer_configurations_cms.cfg_name_unique NOT IN ('categories_posts', 'categories_news')
