錯誤在MySQL查詢

我運行此查詢：錯誤在MySQL查詢

select sm.stockid as 'id',description as 'descripcion',price as 'precio' 
from stockmaster as 'sm', prices as 'pc' 
where 
sm.stockid=pc.stockid and 
sm.stockid='ESPOLVOREO' and 
curdate() between pc.startdate and pc.enddate;

，我不斷收到這個錯誤，我沒有權原因：/

#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''sm', prices as 'pc' where sm.stockid=pc.stockid and sm.stockid='ESPOLVOREO' a' at line 2

我直接運行查詢在分貝。謝謝

不要將表別名放在引號中。

from stockmaster as sm, prices as pc

誰說別名不能用引號引起來？ :)關閉。手冊https://dev.mysql.com/doc/refman/4.1/en/identifiers.html我失蹤了什麼？ – user1954544

別名不能用單引號括起來。通常的引用字符是反引號。您可以使用雙引號，但前提是您已啓用ANSI_QUOTES。 – Joni

'SELECT 1 AS 1，2 AS'two';'從官方手冊中，我認爲它默認啓用。（更改關於單引號的答案） – user1954544

description as 'descripcion', price as 'precio'

變化

sm.description as 'descripcion', sm.price as 'precio'

關於你需要表（添加表名前列名）。

如果這是問題，那麼數據庫會抱怨字段列表中模糊的列。這種情況下的錯誤消息顯示了一般語法錯誤。 – Joni

首先，如user3456640所述，不要用別名寫別名。

SELECT sm.stockid AS id, description AS descripcion, price AS precio

其次，你在調用中缺少一些別名。應該看起來像這樣。

SELECT sm.stockid AS id, 
sm.description AS descripcion, 
pc.price AS precio 
FROM stockmaster AS sm, prices AS pc 
where 
sm.stockid=pc.stockid AND 
sm.stockid='ESPOLVOREO' AND 
curdate() BETWEEN pc.startdate AND pc.enddate;
