使用INNER JOIN后搜索SQL查询

Question

在不进行搜索的情况下显示表时，它可以完美打印，而在添加where查询（在不包含内部联接的其他搜索表中可以正常工作）时，则会产生语法错误。 这是代码：

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%'

这是错误的副本：

您的SQL语法有误； 检查与您的MySQL服务器版本相对应的手册以获取正确的语法，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 

关键字的定义顺序为

select
from 
join
where
group by
having
order by
limit
