Question

我有一个DATA类型为date的列，另一个表也有数据类型date。

我使用insert语句插入tab1，如：

insert into tab1 
(Select date_from,col1,col2

from tab2,tab3
where tab2.date_from =tab3.date_from
and tab2.val='DES');

现在这是投掷

SQL Error: ORA-01858: a non-numeric character was found where a numeric was expected
01858. 00000 -  "a non-numeric character was found where a numeric was expected"
*Cause:    The input data to be converted using a date format model was
           incorrect.  The input data did not contain a number where a number was
           required by the format model.
*Action:   Fix the input data or the date format model to make sure the
           elements match in number and type.  Then retry the operation.

使用以下内容时：

merge
INTO    hr.TAB1 trg
using   (
       select * from( select distinct T1.rowid as RID, T2.CODE1, T2.SOURCE_SYSTEM_OWNER, T2.DATE_fROM  ,
       ROW_NUMBER() over (partition BY NAME order by t2.CODE1) rn
        from    HR.TAB1 T1
        join  XX_ORG T2
        on      UPPER(T1.NAME) = UPPER(T2.NAME)
        where   uppeR(T1.name) = upper(T2.NAME))
        where  rn=1
    --    and t1.ORGANIZATION_NAME='TMI Operations, M1'
        ) src
ON      (trg.rowid = src.rid)
when matched then update
    set TRG.CODE1 = SRC.CODE1,
   trg.DATE_fROM=  =SRC.DATE_fROM;

Gtting

    Error report:
SQL Error: ORA-30926: unable to get a stable set of rows in the source tables
30926. 00000 -  "unable to get a stable set of rows in the source tables"
*Cause:    A stable set of rows could not be got because of large dml
           activity or a non-deterministic where clause.

只需删除括号？

insert into tab1 
Select tab3.date_from,col1,col2
from tab2
join tab3 on tab2.date_from =tab3.date_from
where tab2.val='DES'

修改：

您可能需要指定插入的列。像
这样的东西
insert into tab1 (c1, c2, c3) Select ...

ORA-01858：因为日期问题iin插入和合并
