摘要，按日期范围细分日期

Question

这是原始表格，其中包含带有日期和计数的ID列表。我需要对计数进行透视，然后将日期当前日期getdate()分解为桌子上的日期，该日期按0-5天，10-15 ....

Type        Date         Volume
--------    -----        ------
primary     mar 10,2019     1
Sub         mar 8,2019      2
Pending     mar 13,2019     3
XX          mar 4,2019      5

我想要的是显示结果，如下所示：

TYPE     0-5 Days    5-10 Days    11-15 Days    16-20 Days    21-30 Days    Total
primary  1           4            1             6             1             13 
sub      3           5            5             7             0             20 
pending  1           1            1             1             1             5 
         5           10           7             14            2             38 

Answer 1

我假设您正在寻找将日期与当前日期进行比较的卷的有条件总和。并具有汇总功能。

然后这样：

SELECT Type,
 SUM(CASE WHEN DATEDIFF(day,[Date],GetDate()) BETWEEN 0  AND 5  THEN Volume ELSE 0 END) AS [0-5 Days],
 SUM(CASE WHEN DATEDIFF(day,[Date],GetDate()) BETWEEN 6  AND 10 THEN Volume ELSE 0 END) AS [6-10 Days],
 SUM(CASE WHEN DATEDIFF(day,[Date],GetDate()) BETWEEN 11 AND 15 THEN Volume ELSE 0 END) AS [11-15 Days],
 SUM(CASE WHEN DATEDIFF(day,[Date],GetDate()) BETWEEN 16 AND 20 THEN Volume ELSE 0 END) AS [16-20 Days],
 SUM(CASE WHEN DATEDIFF(day,[Date],GetDate()) BETWEEN 21 AND 30 THEN Volume ELSE 0 END) AS [21-30 Days],
 SUM(Volume) AS Total
FROM yourtable
WHERE [Date] >= CAST(GetDate()-30 AS DATE)
GROUP BY Type WITH ROLLUP
