MYSQL「SELECT CASE」查看語法錯誤

Question

我有幾個使用SELECT CASE語法的視圖。但是當我創建一個備份腳本並嘗試恢復時，我得到語法錯誤。但請記住，視圖已成功創建第一個地方。

在我的幾個「SELECT CASE」語法觀就在這裏

DROP VIEW IF EXISTS `v_stockmovement` ; 
CREATE VIEW `v_stockmovement` 
AS 
SELECT stock_mov.id AS ID, 
stock_category.stock_category_code AS categorycode, 
stock_mov_type, 
(SELECT CASE stock_mov_type 
WHEN 1 THEN 'Stock Issue' 
WHEN 2 THEN 'Stock Reorder' 
WHEN 3 THEN 'Stock Adjustment' 
ELSE '' END) AS stock_mov_typedesc, 
(SELECT stock_mov_unitcost * stock_mov_quantity) AS cost, 
stock_mov_comments 
FROM stock_mov 
INNER JOIN stock ON stock.stock_code = stock_mov.stock_mov_linkstockcode 
INNER JOIN stock_category ON stock_category.stock_category_code = stock.stock_linkcategory 
; 

什麼可能我會丟失？

試試這個：（我已經刪除周圍的CASE語句的支架和SELECT）

DROP VIEW IF EXISTS `v_stockmovement` ; 
CREATE VIEW `v_stockmovement` 
AS 
SELECT stock_mov.id AS ID, 
stock_category.stock_category_code AS categorycode, 
stock_mov_type, 
CASE stock_mov_type 
    WHEN 1 THEN 'Stock Issue' 
    WHEN 2 THEN 'Stock Reorder' 
    WHEN 3 THEN 'Stock Adjustment' 
    ELSE '' 
END stock_mov_typedesc, 
stock_mov_unitcost * stock_mov_quantity AS cost, 
stock_mov_comments 
FROM stock_mov 
INNER JOIN stock ON stock.stock_code = stock_mov.stock_mov_linkstockcode 
INNER JOIN stock_category ON stock_category.stock_category_code = stock.stock_linkcategory 
;
