The ORA-01830 error occurs due to an incorrect date format. To resolve this error, you can take the following steps:

  1. Check the date format: Ensure that the input date format matches the date format in the database. You can use the TO_DATE function to convert the input date string into the correct date format.
  2. Check the NLS_DATE_FORMAT parameter: Verify that the NLS_DATE_FORMAT parameter is set correctly. You can use the following statement to query the current value of the NLS_DATE_FORMAT parameter:
  3. Retrieve the value from v$nls_parameters where the parameter is ‘NLS_DATE_FORMAT’.
  4. If the value of the NLS_DATE_FORMAT parameter does not match the date format you expect, you can use the ALTER SESSION statement to change it.
  5. Change the session’s date format to ‘YYYY-MM-DD’.
  6. Please note that changing the NLS_DATE_FORMAT parameter may affect the date format for the entire session.
  7. Check the date string: If you are using a date string, make sure that the format of the string is correct. The date string should match the format specified by the NLS_DATE_FORMAT parameter.
  8. Check the date values: If you are using date values, make sure they are valid. Date values should be within a legal date range and cannot be NULL.

If the above steps do not solve the ORA-01830 error, please provide additional context information, such as the query statement or error stack trace, to better assist you in resolving the issue.
