Sql 将SYSDATE分配给prompt

因此，我的SQL中有一行代码：

AND ((:3 IS NOT NULL
AND A.ADM_CREATION_DT BETWEEN :3 AND SYSDATE)
OR :3 IS NULL
AND :3 = SYSDATE)

我想让它做的是，如果提示符3或：3有一个值，它将获得ADM_CREATION_DT的所有值，该值介于：3和SYSDATE之间-这很好。不起作用的部分是：3为空时应将值设置为当前日期的SYSDATE

我得到以下错误：

由于SQL错误，运行查询时出错，代码=8006，消息=指定的无效数据类型50380

我认为这与将SYSDATE分配给prompt有关，因为它们的数据类型不同

有人知道如何解决这个问题吗？非常感谢你

完整查询如下：

基于您在问题评论中所说的假设是正确的，即当日期为：3时，未提供您想要当前日期之前的所有记录的条件，解决方案是只使用一个锚定日期，在此日期之前，您将保证不会有任何记录。例如1900年1月1日

那么WHERE子句就变成了

A.ADM_CREATION_DT BETWEEN NVL(:3,TO_DATE('01-01-1900','DD-MM-YYYY')) AND SYSDATE

希望有帮助？

这可能会有帮助

我的理解是：

1如果：3不为空，则应根据：3输入的日期和系统日期填充ADM_CREATION_DT

2但如果：3不为空，则ADM_CREATION_DT应设置为SYSDATE或小于SYSDATE，如果是这种情况，则请遵循以下步骤

 select NVL(A.date1,SYSDATE) dt from dummytab A
 where 
 (TO_DATE(:3,'YYYY-MM-DD') IS NOT NULL
  AND  A.date1 BETWEEN TO_DATE(:3,'YYYY-MM-DD') AND SYSDATE)
   OR (TO_DATE(:3,'YYYY-MM-DD') IS NULL
           AND TO_DATE(A.date1,'YYYY-MM-DD') <=  TO_DATE(SYSDATE,'YYYY-MM-DD'));

 select NVL(A.date1,SYSDATE) dt from dummytab A
  where 
  (TO_DATE(:3,'YYYY-MM-DD') IS NOT NULL
  AND  A.date1 BETWEEN TO_DATE(:3,'YYYY-MM-DD') AND SYSDATE)
  OR (TO_DATE(:3,'YYYY-MM-DD') IS NULL);

这里的date1是您的行政创建日期。

请填写完整的查询。无论您尝试什么，SysDate都已经是一个日期值。使用到日期。。。日期值无效。@SNC:已更新以提供完整的sql。您的意思是当：3尚未提供时，您希望所有记录保留到当前日期？这个假设正确吗？@a_horse_，没有名字，我已经更新了它，删除了to_日期，但仍然得到相同的错误。对。对不起。我不想为了这样一个简单的答案而将代码复制到IDE中。现在删除它。
