class DatabaseCreation(BaseDatabaseCreation):

Undocumented

Method	`_create_test_db`	Internal implementation - create the test db tables.
Method	`_create_test_user`	Undocumented
Method	`_destroy_test_db`	Destroy a test database, prompting the user for confirmation if the database already exists. Return the name of the test database created.
Method	`_destroy_test_user`	Undocumented
Method	`_execute_allow_fail_statements`	Execute statements which are allowed to fail silently if the Oracle error code given by `acceptable_ora_err` is raised. Return True if the statements execute without an exception, or False otherwise.

Property	`_maindb_connection`	No summary

Inherited from BaseDatabaseCreation:

Method	`log`	Undocumented
Method	`mark_expected_failures_and_skips`	Mark tests in Django's test suite which are expected failures on this database and test which should be skipped on this database.
Method	`serialize_db_to_string`	Serialize all data in the database into a JSON string. Designed only for test runner usage; will not handle large amounts of data.
Method	`sql_table_creation_suffix`	SQL to append to the end of the test table creation statements.
Instance Variable	`connection`	Undocumented

def _create_test_db(self, verbosity=1, autoclobber=False, keepdb=False):

overrides django.db.backends.base.creation.BaseDatabaseCreation._create_test_db

Internal implementation - create the test db tables.

def _create_test_user(self, cursor, parameters, verbosity, keepdb=False):

Undocumented

def _destroy_test_db(self, test_database_name, verbosity=1):

overrides django.db.backends.base.creation.BaseDatabaseCreation._destroy_test_db

Destroy a test database, prompting the user for confirmation if the database already exists. Return the name of the test database created.

def _destroy_test_user(self, cursor, parameters, verbosity):

Undocumented

def _execute_allow_fail_statements(self, cursor, statements, parameters, verbosity, acceptable_ora_err):

Execute statements which are allowed to fail silently if the Oracle error code given by acceptable_ora_err is raised. Return True if the statements execute without an exception, or False otherwise.

def _execute_statements(self, cursor, statements, parameters, verbosity, allow_quiet_fail=False):

Undocumented

def _execute_test_db_creation(self, cursor, parameters, verbosity, keepdb=False):

def _execute_test_db_destruction(self, cursor, parameters, verbosity):

Undocumented

def _get_test_db_name(self):

overrides django.db.backends.base.creation.BaseDatabaseCreation._get_test_db_name

Return the 'production' DB name to get the test DB creation machinery to work. This isn't a great deal in this case because DB names as handled by Django don't have real counterparts in Oracle.

def _get_test_db_params(self):

Undocumented

def _handle_objects_preventing_db_destruction(self, cursor, parameters, verbosity, autoclobber):

Undocumented

def _switch_to_test_user(self, parameters):

Switch to the user that's used for creating the test database.

Oracle doesn't have the concept of separate databases under the same user, so a separate user is used; see _create_test_db(). The main user is also needed for cleanup when testing is completed, so save its credentials in the SAVED_USER/SAVED_PASSWORD key in the settings dict.

def set_as_test_mirror(self, primary_settings_dict):

overrides django.db.backends.base.creation.BaseDatabaseCreation.set_as_test_mirror

Set this database up to be used in testing as a mirror of a primary database whose settings are given.

def test_db_signature(self):

overrides django.db.backends.base.creation.BaseDatabaseCreation.test_db_signature

Return a tuple with elements of self.connection.settings_dict (a DATABASES setting value) that uniquely identify a database accordingly to the RDBMS particularities.

@cached_property
_maindb_connection =

This is analogous to other backends' _nodb_connection property, which allows access to an "administrative" connection which can be used to manage the test databases. For Oracle, the only connection that can be used for that purpose is the main (non-test) connection.
