我有一个这样创建的物化视图:

    DROP MATERIALIZED VIEW DMSN.SFMV_DS3R_FH_1XRTT_BTS_LVL;

但是当我在蟾蜍中做一个简单select *的事情时,日期显示为空白。在 toad 中,当我双击列中的任何日期字段时,我会返回一个值。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。

当我运行select *sqlplus,它也显示为空白....

SQL> SELECT ROWNUM, T1.D_DTM_DAY FROM SFMV_DS3R_FH_1XRTT_BTS_LVL T1 WHERE ROWNUM < 6;


ROWNUM D_DTM_DAY
     1
     2
     3
     4
     5

关于为什么会发生这种情况的任何想法?

这段代码:

TRUNC(D1."D_DTM", 'fmdd')

... 可能是为了:

TRUNC(D1."D_DTM")

... 或者:

to_number(to_char(D1."D_DTM", 'fmdd'))
