Question

我正在尝试检索特定于用户最小日期的特定日期范围与另一个表格中的最大日期之间的记录数。

这是我到目前为止所做的，但它至少排除了我所知道的13条记录。你能告诉我的逻辑是否有错误吗？

提前感谢您提供的任何输入！

SELECT   rtam.dbo.wfm_process_instance.user_id AS user_id,
         MIN(rtam.dbo.wfm_process_instance.LOCAL_USER_START_TIME) AS Min_Date,
         MAX(rtam.dbo.wfm_process_instance.LOCAL_USER_START_TIME) AS Max_Date,
         0 AS IVR_Calls,
         COUNT(*) AS Total_Calls

         LEFT OUTER JOIN

                     HAVING   rtam.dbo.wfm_process_instance.LOCAL_USER_START_TIME BETWEEN CONVERT (VARCHAR (10), MIN(rtam.dbo.gnr_tbl_72_type.LOCAL_COL_113), 101) AND CONVERT (VARCHAR (10), MAX(rtam.dbo.gnr_tbl_72_type.LOCAL_COL_113), 101))
GROUP BY rtam.dbo.wfm_process_instance.USER_ID
ORDER BY rtam.dbo.wfm_process_instance.USER_ID;

尝试：

HAVING rtam.dbo.wfm_process_instance.LOCAL_USER_START_TIME 
  >= CONVERT(DATE, MIN(rtam.dbo.gnr_tbl_72_type.LOCAL_COL_113)) 
AND rtam.dbo.wfm_process_instance.LOCAL_USER_START_TIME 
  < DATEADD(DAY, 1, CONVERT(DATE, MAX(rtam.dbo.gnr_tbl_72_type.LOCAL_COL_113))

您可能还会考虑使用别名，这样您就不必在代码中重复冗长且容易出错的引用，例如rtam.dbo.wfm_process_instance。

SQL在日期范围之间
