MySQL查詢到MS SQL

Question

我有以下MySQL查詢：

SELECT date, time, custom_id, Number
FROM traffic t
WHERE CONCAT(date, " ", time) BETWEEN "01/06/2014 00:00" AND "01/10/2014 23:00"
AND Number = 
(SELECT MAX(CAST(Number as SIGNED)) FROM traffic WHERE t.date = date and t.custom_id = custom_id)
ORDER BY date, CAST(Number as SIGNED) DESC, custom_id

這是MySQL中的SQLFiddle（正在運行）： http ://sqlfiddle.com/#!2/6e1248/3

如何將其轉換/翻譯為MS SQL？ SQLFiddle（不起作用）： http ://sqlfiddle.com/#!6/6e124/1

提前致謝

Answer 1

SELECT date, time, custom_id, Number
FROM traffic t
WHERE CONCAT(date, ' ', time) BETWEEN '01/06/2014 00:00' AND '01/10/2014 23:00'
AND Number = 
(SELECT MAX(CAST(Number as smallint)) FROM traffic WHERE t.date = date and t.custom_id = custom_id)
ORDER BY date, CAST(Number as smallint) DESC, custom_id

Answer 2

主要問題是SQL Server不喜歡使用"來封裝字符串，它們將被視為列名，從而刪除了這些（和CAST ）起作用：

SELECT date, time, custom_id, Number
FROM traffic t
WHERE CONCAT(date, ' ', time) BETWEEN '01/06/2014 00:00' AND '01/10/2014 23:00'
AND Number = 
(SELECT MAX(Number) FROM traffic WHERE t.date = date and t.custom_id = custom_id)
ORDER BY date, Number DESC, custom_id

編輯：糟糕，只是注意到需要演員。 有關示例，請參閱@ bdn02的答案。
