使用INNER JOIN后搜索SQL查詢

Question

在不進行搜索的情況下顯示表時，它可以完美打印，而在添加where查詢（在不包含內部聯接的其他搜索表中可以正常工作）時，則會產生語法錯誤。 這是代碼：

SELECT Date_entered, photo1, photo2, UserName, reserveName, species FROM Plant_Reserves 
                        INNER JOIN Plant_Species ON Plant_Reserves.plantID = Plant_Species.plantID 
                        INNER JOIN reserves ON Plant_Reserves.reserveID = reserves.reserveID
                        ORDER BY UserName WHERE UserName LIKE '%$search%'

這是錯誤的副本：

您的SQL語法有誤； 檢查與您的MySQL服務器版本相對應的手冊以獲取正確的語法，以在第4行的'WHERE UserName LIKE'％zz％'附近使用

Answer 1

order by前order by where

SELECT Date_entered, photo1, photo2, UserName, reserveName, species 
FROM Plant_Reserves 
INNER JOIN Plant_Species ON Plant_Reserves.plantID = Plant_Species.plantID 
INNER JOIN reserves ON Plant_Reserves.reserveID = reserves.reserveID
WHERE UserName LIKE '%$search%'
ORDER BY UserName 

關鍵字的定義順序為

select
from 
join
where
group by
having
order by
limit
