Question

我有这个搜索查询，我想基于“folder_restriction”过滤结果，但似乎AND子句不过滤结果。我哪里做错了？

    SELECT * 
     FROM mod_images
     LEFT JOIN mod_folders 
       ON folder_id = image_folder_id
     LEFT JOIN mod_cats 
       ON cat_id = folder_cat_id                    
    WHERE ((`folder_number` LIKE '%".$search."%') OR ('%".$search."%')) OR
          ((`titule` LIKE '%".$search."%') OR ('%".$search."%'))        OR
          ((`description` LIKE '%".$search."%') OR ('%".$search."%'))   OR
      AND `folder_restriction` = '0'
    LIMIT 2000

Answer 1

试试这个： -

SELECT * FROM mod_images
    LEFT JOIN mod_folders ON folder_id = image_folder_id
    LEFT JOIN mod_cats ON cat_id = folder_cat_id                    
    WHERE
     ((`folder_number` LIKE '%".$search."%') OR
     (`titule` LIKE '%".$search."%') OR
     (`description` LIKE '%".$search."%' ))
    AND `folder_restriction` = '0'
    LIMIT 2000

或尝试删除最后的OR： -

SELECT * 
 FROM mod_images
 LEFT JOIN mod_folders 
   ON folder_id = image_folder_id
 LEFT JOIN mod_cats 
   ON cat_id = folder_cat_id                    
WHERE (((`folder_number` LIKE '%".$search."%') OR ('%".$search."%')) OR
      ((`titule` LIKE '%".$search."%') OR ('%".$search."%'))        OR
      ((`description` LIKE '%".$search."%') OR ('%".$search."%')))   
  AND `folder_restriction` = '0'
LIMIT 2000

SELECT *

     LEFT JOIN mod_folders 
       ON folder_id = image_folder_id
     LEFT JOIN mod_cats 
       ON cat_id = folder_cat_id                    
    WHERE (((`folder_number` LIKE '%".$search."%') OR ('%".$search."%')) OR
          ((`titule` LIKE '%".$search."%') OR ('%".$search."%'))        OR
          ((`description` LIKE '%".$search."%') OR ('%".$search."%')))
      AND `folder_restriction` = '0'
    LIMIT 2000
