Ora-01858 a non numeric character....... [message #389906]

We have been running a report that worked for months. Today when running the same report (no changes done to report) we get an ORA-01858 A non-numeric character was found where a numeric was expected.

The only difference is that the user has got a new PC. Could this be a data error. Or has a date in the format DD-MON-RRRR has got to be set in the regedit file on the pc?

Thanks

ORA-01858: 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.

Hi Michael

Can I rule out the possibility that the setup on the new PC could also be the cause of this error.

Thanks

Yes if the new PC is not configured for the usual territory and/or language.

I have found that on the database that this client is using, the nls_date_fromat is set as 'RRRRMMDD'. The report was doing a to_date of a field with a format mask of 'DD-MON-RRRR'.

I refreshed the test database from the clients site. The nls_date_format on the test database is 'DD-MON-RR'. Ran the same report and it works fine.

Could the nls_date_format throw out this error. Have now asked our dba to set the nls_date_format on the test database to 'RRRRMMDD' and would see what happens when I run the report.

No, change your code so you NEVER use implicit/default format.

Out of curiosity I changed the nls_date_format to 'RRRRMMDD' on our test database and the report still works fine.

The user had a new pc installed and am now wondering if there are any parameters that needs to be set in the regedit file. Perhaps these parameters are missing and causing the error.
