但是当我在蟾蜍上做一个简单的select *时，日期显示空白。在toad中，当我双击列中的任何日期字段时，我得到一个值。我不确定这里发生了什么，但由于某种原因，应用程序甚至无法查询日期列。
当我在select *中运行sqlplus时，它也会显示空白....
SQL> SELECT ROWNUM, T1.D_DTM_DAY FROM SFMV_DS3R_FH_1XRTT_BTS_LVL T1 WHERE ROWNUM < 6;

关于为什么会发生这种情况的任何想法？
答案 0 :(得分：0)
此代码：
TRUNC(D1."D_DTM", 'fmdd')
......可能是：
TRUNC(D1."D_DTM")
......或：
to_number(to_char(D1."D_DTM", 'fmdd'))
