我遇到了问题，我的公司有一个客户满意度计划，它从我们的数据库系统中的不同表中获取大量数据。
问题是我只想显示特定部门的客户满意度百分比，因此只显示此特定部门的员工。
表中的问题是我从中获取员工，如果他们已经切换了部门，那么同一员工会有重复，所以如果他们在1年前在1个部门工作，今天又搬到另一个部门，它会告诉我即使他们已经切换了部门，因为他们使用相同的ID注册，我们的SQL程序中的逻辑代码如下：
"KS_DRIFT.V_AGENT_ALLOCATION age ON " + (queryParams.JoinOnFirstAgent ? "FØRSTE_AGENT" : "SIDSTE_AGENT") + " = age.AGENT_INITIALS AND TRUNC(TIDSPUNKT) BETWEEN ALLOCATION_START AND ALLOCATION_END " +
"WHERE " +
"TRUNC(TIDSPUNKT) BETWEEN " + OracleConversion.ToOracleDate(queryParams.Interval.Lower) + " AND " + OracleConversion.ToOracleDate(queryParams.Interval.Upper)
我不确定如何根据此sql查询确保它仅取出当前员工处于活动状态的部门？我希望任何人都可以帮助我更接近解决方案。

只需在sysdate和分配列上添加测试
