Question

它在BigQuery中可以正常运行，但我在MS SQL Server中没有得到正确的信息；

CASE 
    WHEN COUNT( RSM.RECEIVED_AT BETWEEN DATEADD(day, -84,UDATE.SQLDate) AND UDATE.SQLDate ) >= 1 
    AND COUNT(SAL.DATE BETWEEN DATEADD(day, -7, UDATE.SQLDate) AND UDATE.SQLDate) >=2  
    AND COUNT(SAL.DATE BETWEEN DATEADD(day, -14, UDATE.SQLDate) AND DATEADD(day, -7, UDATE.SQLDate)) >= 2 
THEN 'True' 
ELSE 'False' END AS AVAILABLE

出了什么问题？

'）'附近的语法不正确。

我怀疑你所追求的是：

CASE
            WHEN COUNT(CASE WHEN RSM.RECEIVED_AT BETWEEN DATEADD(DAY, -84, UDATE.SQLDate) AND UDATE.SQLDate THEN 1 END) >= 1
             AND COUNT(CASE WHEN SAL.[DATE] BETWEEN DATEADD(DAY, -7, UDATE.SQLDate) AND UDATE.SQLDate THEN 1 END) >= 2
             AND COUNT(CASE WHEN SAL.[DATE] BETWEEN DATEADD(DAY, -14, UDATE.SQLDate) AND DATEADD(DAY, -7, UDATE.SQLDate) THEN 1 END) >= 2 THEN 'True'
            ELSE 'False'
       END AS AVAILABLE;

正如我在评论中说的：“ COUNT（或任何其他聚合函数）中不能有布尔表达式，它需要一个标量表达式。”

COUNT内的MS Sql Server语句
