ORA-01843 不是有效月份 - 比较日期

问题描述

尝试从按日期过滤的表中选择数据时遇到问题.

例如:

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = '23/04/49';

Oracle 错误是:

通知错误:错误 SQL: ORA-01843: mes no válido01843. 00000 - 无效月份"*原因:*行动:

可能是表的源数据损坏了，在这种情况下:

• 我该如何解决这个问题?
• 我可以将此日期更改为空吗?

这个select的结果，select * from nls_session_parameters;，是:

您应该使用 to_date 函数 (oracle/functions/to_date.php)

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');

I have a problem when try to select data from a table filtering by date.

For example:

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = '23/04/49';

The Oracle Error is:

Informe de error:
Error SQL: ORA-01843: mes no válido
01843. 00000 -  "not a valid month"
*Cause:    
*Action:

Probably the source data of table is corrupted, in this case:

• How can i solve this problem?
• Can I change this dates for null?

The results of this select, select * from nls_session_parameters; , is:

You should use the to_date function (oracle/functions/to_date.php )

SELECT * FROM MYTABLE WHERE MYTABLE.DATEIN = TO_DATE('23/04/49', 'DD/MM/YY');
