cx_Oracle has a major new release under a new name and homepage python-oracledb.
New projects should install python-oracledb instead of cx_Oracle.
All exceptions raised by cx_Oracle are inherited from
See Exceptions for more details on the various exceptions
defined by cx_Oracle. See the exception handling section in the
API manual for more details on the information available
when an exception is raised.
Applications can catch exceptions as needed. For example, when trying to add a customer that already exists in the database, the following could be used to catch the exception:
try: cursor.execute("insert into customer values (101, 'Customer A')") except cx_Oracle.IntegrityError: print("Customer ID already exists") else: print("Customer added")
If information about the exception needs to be processed instead, the following code can be used:
try: cursor.execute("insert into customer values (101, 'Customer A')") except cx_Oracle.IntegrityError as e: error_obj, = e.args print("Customer ID already exists") print("Error Code:", error_obj.code) print("Error Message:", error_obj.message) else: print("Customer added")
