Question

我收到错误

  

分组条款中不允许使用Teradata Orderer分析功能

当我运行此查询时：

SELECT
    CC.CASE_ID as CASE_ID,
    FIRST_VALUE(CC.CASE_OWN_NM) OVER(PARTITION BY CC.CASE_ID) as FST_AGNT_CASE_OWN_NM,
    FIRST_VALUE(CC.LSTMOD_BY_AGNT_PRFL_NM) OVER(PARTITION BY CC.CASE_ID) as FST_AGNT_PRFL_NM,

我尝试了answer by anwaar_hell并稍微修改了一些列，但我仍然收到错误：

  

子查询中不允许使用有序分析函数
