将日期文本插入表中会返回“不是有效月份”

Question

My NLS_DATE_FORMAT is DD/MM/YY

When I enter values like these

Insert into EVENTREQUEST (EVENTNO,DATEHELD,DATEREQ,FACNO,CUSTNO,DATEAUTH,STATUS,ESTCOST,ESTAUDIENCE,BUDNO) values ('E100',to_date('25/10/13'),to_date('06/06/13'),'F100','C100',to_date('08/06/13'),'Approved',5000,80000,'B1000');

The row is inserted but when I use the following Format this error message appears.

Error starting at line 2 in command:

Insert into EVENTREQUEST (EVENTNO,DATEHELD,DATEREQ,FACNO,CUSTNO,DATEAUTH,STATUS,ESTCOST,ESTAUDIENCE,BUDNO) 
values ('E101',to_date('26-OCT-13','DD-MON-RR'),to_date('28-JUL-13','DD-MON-RR'),'F100','C100',null,'Pending',5000,80000,'B1000')

Error report:

SQL Error: ORA-01843:not a valid month

Can anybody help?

Answer 1

Exists somewhere else: Oracle insert failure : not a valid month

Maybe if you specify NLS_DATE_LANGUAGE ?

Insert into EVENTREQUEST (EVENTNO,DATEHELD,DATEREQ,FACNO,CUSTNO,DATEAUTH,STATUS,ESTCOST,ESTAUDIENCE,BUDNO) 
values ('E101',to_date('26-OCT-13','DD-MON-RR', 'NLS_DATE_LANGUAGE = AMERICAN'),to_date('28-JUL-13','DD-MON-RR', 'NLS_DATE_LANGUAGE = AMERICAN'),'F100','C100',null,'Pending',5000,80000,'B1000')
