我有简单的表员工id，开始年份，结束年份。我必须找出有多少员工在最低年份工作。如果分年是2000年和最大。应该列出所有这些年份从2000年到2017年的工作雇员人数每年有多少员工工作？

NOT_ACTIVE暗示什么？它是否会影响报告查询？有许多重复的行像第2行和第4行。如果相同的USER_ID在特定年份中有多个条目，那么您是否将它们作为单独的或相同的添加？ – Slkrasnodar

在这种情况下，我们只需要为特定的user_id选择ACTIVE GROUP条目，并从VALID_FROM和max中选择最小值。 VALID_TO的值来检查某个员工在公司工作的时间（时间范围）。除此之外，我们通过从DATE中提取年份（VALID_FROM，VALID_TO＆SYSDATE作为实际年份=在这种情况下，我假定提取（年份从SYSDATE）应该被处理为最大年份2017 =最大值而不是9999） MAX;） – HankerPL
