Question

在我的 PS 查询上单击 HTML link 时，出现错误：发生 SQL 错误。有关详细信息，请查阅您的系统日志。我想知道这个错误的原因是什么，如果它是我的 PS 查询，因为它非常简单。请参阅下面的 SQL：

SELECT A.EMPLID, A.ACAD_CAREER, A.STDNT_CAR_NBR, A.ADM_APPL_NBR,

     AND A.SAD_PB_CAS_STATUS IN ('ASG','USD') ));

谁能帮我解决这个错误？非常感谢。

这部分看起来不对：

to_date(a.sad_pb_cas_statdt,'DD-MON-YY') = to_date(sysdate,'DD-MON-YY')

sysdate 已经是一个日期（sad_pb_cas_statdt 可能也是），因此对其应用任何字符函数都是自找麻烦。如果 nls_date_format 设置为与指定格式 'DD-MON-YY' 不兼容的任何内容，它将失败。（例如，您可以使用 'DD-MON-RRRR'，但不能使用 YYYY-MM-DD。）

尝试将其更改为：

a.sad_pb_cas_statdt >= trunc(sysdate) and a.sad_pb_cas_statdt < trunc(sysdate) +1

或

a.sad_pb_cas_statdt between trunc(sysdate) and trunc(sysdate) + interval '86399' second
