MYSQL“SELECT CASE”查看语法错误

Question

我有几个使用SELECT CASE语法的视图。但是当我创建一个备份脚本并尝试恢复时，我得到语法错误。但请记住，视图已成功创建第一个地方。

在我的几个“SELECT CASE”语法观就在这里

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 
; 

什么可能我会丢失？

Answer 1

试试这个：（我已经删除周围的CASE语句的支架和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 
;
