INSERT语句中的“Not a valid month”

I have an sql statement:

我有一条sql语句:

Insert into MYSCHEMA.TABLE1 (ID,MY_DATE) values (167600,to_timestamp('15-APR-14 01.36.58.803000000 PM','DD-MON-RR HH.MI.SS.FF AM'));

As I read this format is correct (as described here) but oracle returns an error SQL Error: ORA-01843: not a valid month. Any idea how to solve this problem? I use Oracle Database 11b Express Edition.

正如我读到的这种格式是正确的(如本文所述)，但是oracle返回一个错误的SQL错误:ORA-01843:不是一个有效的月份。你知道怎么解决这个问题吗?我使用Oracle数据库11b Express Edition。

Unless you have a trigger on the table that is setting a date or timestamp column, which would give some indication in the full error stack, it sounds like your NLS_DATE_LANGUAGE is not expecting an English-language month abbreviation.

除非您的表上有一个正在设置日期或时间戳列的触发器，该触发器将在完整的错误堆栈中给出一些指示，否则您的NLS_DATE_LANGUAGE不希望使用英语月份缩写。

What you have is valid in English:

你所拥有的在英语中是有效的:

alter session set nls_timestamp_format = 'RR/MM/DD HH24:MI:SSXFF';
alter session set nls_date_language ='ENGLISH';

select to_timestamp('15-APR-14 01.36.58.803000000 PM',
  'DD-MON-RR HH.MI.SS.FF AM') as my_date
from dual;

MY_DATE                   
---------------------------
14/04/15 13:36:58.803000000

But if your session's default date language is Polish (guessing from your profile) it will give this error - with the error message still in English:

但是如果会话的默认日期语言是波兰语(从您的个人资料中猜测)，它将会产生这个错误——错误消息仍然是英语:

alter session set nls_date_language ='POLISH';

select to_timestamp('15-APR-14 01.36.58.803000000 PM',
  'DD-MON-RR HH.MI.SS.FF AM') as my_date
from dual;

SQL Error: ORA-01843: not a valid month
01843. 00000 -  "not a valid month"

If you don't want to set your session to English you can override that for a specific statement by giving the optional third parameter to to_timestamp():

如果您不想将会话设置为英语，您可以通过为to_timestamp()提供可选的第三个参数来覆盖特定语句:

alter session set nls_date_language ='POLISH';

select to_timestamp('15-APR-14 01.36.58.803000000 PM',
  'DD-MON-RR HH.MI.SS.FF AM',
  'NLS_DATE_LANGUAGE=ENGLISH') as my_date
from dual;

MY_DATE                   
---------------------------
14/04/15 13:36:58.803000000

You can also avoid the issue entirely by using month numbers instead of month names, or using the ANSI timestamp literal syntax:

您还可以使用月号而不是月名来完全避免这个问题，或者使用ANSI时间戳字面语法:

select timestamp '2014-04-15 13:36:58.803' from dual;

TIMESTAMP'2014-04-1513:36:58.803'
---------------------------------
14/04/15 13:36:58.803000000

These methods also all work for date columns; the to_date() function is affected by NLS settings in the same way and has the same optional date language parameter.

这些方法也适用于日期列;to_date()函数也受NLS设置的影响，具有相同的可选日期语言参数。
