Question

我想返回一个唯一ID的计数以及自创建记录以来的分钟数。

我有这个查询：

SELECT DISTINCT
  batchid AS 'ID'
, COUNT(batchid) AS 'Count'
, DATEDIFF (MINUTE,CONVERT(char(10),MIN([createdOn]), 108),CONVERT(char(10),GETDATE(), 108))
FROM [UpdateRecords]
WHERE [status] = 'Pending'
GROUP BY batchId,createdOn
ORDER BY batchId

它返回ID，计数和分钟数。

ID      Count  Minutes
171836  1      28
171836  4      28
171836  10     28
171836  21     28

出现相同的ID会出现多次的问题。当加在一起时，该ID的计数是准确的。

我想通过ID和分钟数来进行计数

ID Count Minutes 171836 36 28

如何用几分钟来做到这一点？可以显示小时和分钟吗？

Answer 1

您需要按“选择”中的相同项目分组：

SELECT 
batchid AS 'ID'
, COUNT(batchid) AS 'Count'
, DATEDIFF (MINUTE,CONVERT(char(10),MIN([createdOn]), 108),CONVERT(char(10),GETDATE(), 108))
FROM [UpdateRecords]
WHERE [status] = 'Pending'
GROUP BY batchId, DATEDIFF (MINUTE,CONVERT(char(10),MIN([createdOn]), 108),CONVERT(char(10),GETDATE(), 108))
ORDER BY batchId

Answer 2

我认为您想要这样的东西：

SELECT batchid AS ID,
       COUNT(*) AS Count,
       SUM(DATEDIFF(MINUTE, CONVERT(time, createdOn), CONVERT(time, GETDATE()))
FROM UpdateRecords
WHERE status = 'Pending'
GROUP BY batchId
ORDER BY batchId

datediffs的不同计数不是很明显
