我认为您从输出中看到重复的原因是因为您只在输出中显示没有时间的日期。每个WONUM日期（WO_DATE，RFQ_DATE）可能有多行。

如果您更改日期格式以包含时间：

alter session set nls_date_format='dd-MON-yy hh:mi:ss AM';

然后再次运行您的查询，您应该看到相同WONUM的行在同一天的时间不同。

如果您真的只想要日期的不同价值（无视时间），请将您的查询更改为：

select  distinct  WORKORDER.WONUM ,  WORKORDER.SVCGRP ,WORKORDER.STATUS ,
WORKORDER.DESCRIPTION ,trunc(WORKORDER.REPORTDATE) WO_DATE ,trunc(RFQLINE.ENTERDATE) RFQ_DATE,
PRLINE.RFQNUM,PRLINE.PONUM ,PRLINE.prnum  ,PRLINE.ENTERDATE PR_DATE,POLINE.ENTERDATE from ...
