oracle - ORA-01861: 使用存储过程时文字与格式字符串不匹配

Question

我正在尝试在存储过程中执行以下语句

execute immediate 'insert into tmp_vw(TMP_SRC, SNAP_DATE) 
                   select TMP_SRC,Max(SNAP_DATE) as SNAP_DATE 
                   from tmp_demand group by TMP_SRC'

ORA-01861: 文字与格式字符串不匹配

SNAP_DATE 的类型为 Date，值的格式为“2001-01-01”

Answer 1

您必须将 TMP_DEMAND.SNAP_DATE 作为 varchar2。

例如。

SQL> create table tmp_vw(TMP_SRC varchar2(20), SNAP_DATE date);

Table created.

SQL> create table tmp_demand(TMP_SRC varchar2(20), SNAP_DATE varchar2(20));

Table created.

SQL> alter session set nls_date_format ='yyyy-mm-dd';

Session altered.

SQL> insert into tmp_demand select 'a', sysdate from dual;

1 row created.

SQL> alter session set nls_date_format ='dd/mm/yyyy';

Session altered.

SQL> insert into tmp_vw(TMP_SRC, SNAP_DATE) select TMP_SRC,Max(SNAP_DATE) as SNAP_DATE from tmp_demand group by TMP_SRC;
insert into tmp_vw(TMP_SRC, SNAP_DATE) select TMP_SRC,Max(SNAP_DATE) as SNAP_DATE from tmp_demand group by TMP_SRC
                                                      *

ORA-01861: literal does not match format string

您也需要将临时表更改为最新以避免错误。
