getEinzelrisiko方法的问题。此方法返回整数，PageblockTable值属性的类型应为List

我已经更改了Visualforce页面，请检查这个

希望它能帮助您

我已将查询分为两个查询，并对其进行了测试。 但是，现在我得到了一个查询列表，但我只想要一个查询计数。可以再次查看代码

谢谢， 萨沙

谢谢你的支持。但我仍然得到一个未知属性“Gruppenvertrag_c9.CountClass.Count_u18”的错误。谢谢，peXTry将CountClass属性设置为public并检查..我已经编辑了答案。嘿，非常感谢，但现在我得到的visualforce错误集合大小1.172超过了最大大小1.000。通过筛选条件限制SOQL查询大小..如果适用，请将此答案标记为OK。您是否有其他方法来处理此查询。首先，我对所有年龄段的人都进行了查询，我认为如果我按照上面的方式进行查询，速度会慢一些。我可以用数组进行查询吗？
