進入「新進商品」時，SQL執行錯誤

[cct0201]

mysql error: [1054: Unknown column 'p.manufacturers_id' in 'on clause'] in EXECUTE("select count(distinct p.products_id) as total from products p, categories c, products_to_categories p2c left join manufacturers m on p.manufacturers_id = m.manufacturers_id left join products_description pd on p.products_id = pd.products_id and pd.language_id = '1' where c.categories_status=1 and p.products_id = p2c.products_id and c.categories_id = p2c.categories_id and products_status = '1' order by p.products_date_added DESC")

每次要進入新進商品時，就會看到沒有p.manufacturers_id這個欄位的錯
可是我檢查資料庫應該是有
不知道為什麼會這樣
請前輩們幫我看一下囉　謝謝

參考一下kiss2000大大在KMD提出的解決方式
http://www.kmd.com.tw/Forum/viewtopic.php?...=Unknown+column
MySQL 5.x 上出現有關 Left Join 的問題時, 可以下列方法來解決。

Ｓelect 句子有一個 Left Join 時:
1. 在 From 後面加上一個 (
2. 在 Left join 前加上一個 )

Ｓelect 句子有兩個 Left Join 時:
1. 在 From 後面加上 ((
2. 在第一個 Left join 前加上一個 )
3. 在第兩個 Left join 前加上一個 )



答案在 OScommerce 的網站上:

-------------------------------------------
Here is my suggestion to correct this 1054 Error with Left join :

1. I give you the tips : every time you see a FROM followed by 1 or more LEFT JOIN, proceed like this :

ONE LEFT JOIN :

a. after the FROM add (
before the LEFT JOIN add )

TWO LEFT JOIN :

b. after the FROM add ((
before the 1st LEFT JOIN add )
before the 2nd LEFT JOIN add )
