IIF聲明幫助 - 總和值大於或等於

Question

我被卡住了，需要建議。 這可能很簡單，但是，我是初學者，想盡快學習，所以請耐心等待。 我有一個包含「A」/「P」格式考勤數據的表格。我試圖在報告中顯示一個班級內有多少人在日期範圍內錯過了三次或更多次。大多數情況下，我有SQL語句執行所有工作，但有一個例外。我可以顯示某人錯過了多少次的總和，但我無法弄清楚如何僅顯示缺課時間超過3次的學生。

=SUM(IIF(Fields!Attendance.Value ="A",1,NOTHING))

如果我寫這樣的表達： 我進入上我想要的數據，在返回列的表達式如下

=SUM(IIF(Fields!Attendance.Value ="A",1,NOTHING))>=3

我得到TRUE/FALSE返回。如果我可以弄清楚如何只顯示TRUE的回報，那就沒問題了。

任何意見是讚賞！

我的整個SQL語句 - 還有兩個其他數據集被調用來將數據拉入到這個數據集中。

想要試試這個嗎？

道岔：你可能要檢查： 兩個[Start Date]和[End Date]設置爲CATD.occurrence_end_time

SELECT  *

     SELECT  smgp_group.group_id 
       , smgp_group.group_name

       , core_v_person_basic.birth_date AS Birthdate 
       , '*' + CONVERT(varchar, core_v_person_basic.person_id) + '*' AS person_id 
       , core_v_person_basic.street_address_1 
       , core_v_person_basic.city + ',' + core_v_person_basic.state + ' ' + core_v_person_basic.postal_code AS Citystatezip
