Question

ORIGINAL QUERY：

select DISTINCT  a.UniversalMemberID, a.Name, a.DOB, a.[First Service Date], 
(select count(b.UniversalMemberID)
      from WCV b
      where b.[First Service Date] <= a.[First Service Date] 
      and a.UniversalMemberID = b.UniversalMemberID) 
      AS  Visit_CNT
from WCV as a
ORDER by a.UniversalMemberID, a.[First Service Date]

需要将上述查询的结果插入临时表#TEMP

不断返回此错误：

Answer 1

This SqlFiddle似乎工作得很好......这是你正在尝试做的吗？

SELECT DISTINCT  a.UniversalMemberID, a.Name, a.DOB, a.[First Service Date],
(SELECT count(b.UniversalMemberID)
      FROM WCV b
      WHERE b.[First Service Date] <= a.[First Service Date]
      AND a.UniversalMemberID = b.UniversalMemberID)
      AS  Visit_CNT
into #MyTempTable
FROM WCV AS a
ORDER BY a.UniversalMemberID, a.[First Service Date]


Select * from #MyTempTable

Answer 2

当我遇到查询问题时，我总是尝试将其拆分并查看是否有问题，如果您尝试分开查询，从SELECT *这样的泛型开始到更多过滤查询，它也会有所帮助。

SELECT
DISTINCT a.UniversalMemberID, a.Name, a.DOB, a.[First Service Date], 
(
SELECT count(b.UniversalMemberID) 
FROM 
WCV AS b 
WHERE 
b.[First Service Date] <= a.[First Service Date] and a.UniversalMemberID = b.UniversalMemberID
) AS Visit_CNT 
FROM 
WCV as a 
ORDER by a.UniversalMemberID, a.[First Service Date]

我将首先尝试从括号中进行查询，然后开始添加内容。希望能帮助到你。
