IIF声明帮助 - 总和值大于或等于

Question

我被卡住了，需要建议。 这可能很简单，但是，我是初学者，想尽快学习，所以请耐心等待。 我有一个包含“A”/“P”格式考勤数据的表格。我试图在报告中显示一个班级内有多少人在日期范围内错过了三次或更多次。大多数情况下，我有SQL语句执行所有工作，但有一个例外。我可以显示某人错过了多少次的总和，但我无法弄清楚如何仅显示缺课时间超过3次的学生。

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

如果我写这样的表达： 我进入上我想要的数据，在返回列的表达式如下

=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显示TRUE的回报，那就没问题了。

任何意见是赞赏！

我的整个SQL语句 - 还有两个其他数据集被调用来将数据拉入到这个数据集中。

SELECT  smgp_group.group_id 
    , smgp_group.group_name 
    , core_v_person_basic.last_name + ', ' + core_v_person_basic.nick_name as Name

    , '*' + CONVERT(varchar, core_v_person_basic.person_id) + '*' AS person_id 
    , core_v_person_basic.street_address_1

想要试试这个吗？

道岔：你可能要检查： 两个[Start Date]和[End Date]设置为CATD.occurrence_end_time
