選擇查詢不工作時MSSQL2014 我的架構使用的變量是: -使用可變Select查詢MSSQL中沒有運行
CREATE TABLE product
(idproduct int, name varchar(50), description varchar(50), tax decimal(18,0))
INSERT INTO product
(idproduct, name, description,tax)
VALUES
(1, 'abc', 'This is abc',10),
(2, 'xyz', 'This is xyz',20),
(3, 'pqr', 'This is pqr',15)
CREATE TABLE product_storage
(idstorage int,idproduct int,added datetime, quantity int, price decimal(18,0))
INSERT INTO product_storage
(idstorage,idproduct, added, quantity,price)
VALUES
(1, 1, 2010-01-01,0,10.0),
(2, 1, 2010-01-02,0,11.0),
(3, 1, 2010-01-03,10,12.0),
(4, 2, 2010-01-04,0,12.0),
(5, 2, 2010-01-05,10,11.0),
(6, 2, 2010-01-06,10,13.0),
(7, 3, 2010-01-07,10,14.0),
(8, 3, 2010-01-07,10,16.0),
(9, 3, 2010-01-09,10,13.0)
,我下面的命令執行: -
declare @price1 varchar(10)
SELECT p.idproduct, p.name, p.tax,
[@price1]=(SELECT top 1 s.price
FROM product_storage s
WHERE s.idproduct=p.idproduct AND s.quantity > 0
ORDER BY s.added ASC),
(@price1 * (1 + tax/100)) AS [price_with_tax]
FROM product p
;
這不在MSSQL中工作,請幫助我。 詳細檢查http://sqlfiddle.com/#!6/91ec2/296
和我的查詢工作在MYSQL 檢查細節: - http://sqlfiddle.com/#!9/a71b8/1
一個很好的例子爲一個很好的問題,感謝小提琴 – Shnugo
