Question

我需要帮助将此MS Access查询转换为SQL Server 2012：

TRANSFORM 
SUM(TTQTY * qty) AS quantity 
SELECT matlprodcode AS product_code, cvend_name AS supplier, CITMCD AS material, matldesc AS description, MIN(unit_cost) AS unit_cost 
FROM acs_Budget 
WHERE matlprodcode NOT LIKE ';I8*' 
AND matlprodcode NOT LIKE 'I1' 
GROUP BY matlprodcode, cvend_name, CITMCD, matldesc 
PIVOT budgetmonth;

我在这里尝试过转换它：

SELECT matlprodcode AS product_code, 
    cvend_name AS supplier, 
    CITMCD AS material, 
    matldesc AS 'description', 
    MIN(unit_cost) AS unit_cost 
FROM
(
   SELECT TTQTY, qty, matlprodcode, cvend_name, CITMCD, matldesc, unit_cost, budgetmonth FROM acs_Budget WHERE matlprodcode NOT LIKE ';I8*' AND matlprodcode NOT LIKE 'I1' 
) AS T
PIVOT
(
   SUM(TTQTY * qty)
) P

这是对的吗？有什么建议？或者我离开了？

我自己想通了。我不确定这是否会对其他人有所帮助，但这里是最终查询将在SQL Server中工作。我从MS Access转换了这个：

SELECT pt.* FROM 
(SELECT SUM(TTQTY * qty) AS quantity, matlprodcode AS product_code, cvend_name AS supplier, CITMCD as material, matldesc AS description, MIN(unit_cost) AS unit_cost, budgetmonth 
FROM acs_Budget 
WHERE matlprodcode NOT LIKE ';I8*' 
AND matlprodcode NOT LIKE 'I1' 
GROUP BY matlprodcode, cvend_name, CITMCD, matldesc, budgetmonth) AS src 
PIVOT (MIN(quantity) FOR src.budgetmonth IN ([4/1/2015], [5/1/2015], [6/1/2015], [7/1/2015], [8/1/2015], [9/1/2015], [10/1/2015], [11/1/2015], [12/1/2015], [1/1/2016], [2/1/2016], [3/1/2016])) AS pt;

一些帮助我的事情：

首先，我选择了我想看到的一切。包括MS Access正在转换和转动的内容。
然后我发现MS Access每个列都在转动，在这种情况下是数量。
所以我做了数量的MIN，因为PIVOT需要一个聚合函数。
在聚合函数之后，您需要MS Access正在使用的实际PIVOT，它位于FOR之后。
然后我做了一些类似于SELECT DISTINCT预算单从FROM acs_Budget获得的东西，以获得我可以转动的每个项目，这就是IN进来的地方。

不确定我是否解释得很好，但这就是我的工作方式！
