When I try to read data from a CSV file using an Oracle external table, I get the following error:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
What are the possible causes of this error, and how can I fix it so that the external table can read the CSV file successfully?
and Connor said...
Common causes
- user does not have access the database directory object
- the OS user that the database is running as does not have access to the read the actual file on OS (or the directory in which the file resides)
- file is not present or not correctly named.
We'd need to see the full DDL and the full error stack
