django.contrib.gis.db.backends.mysql.base.DatabaseWrapper

Inherited from DatabaseWrapper:

Method	check_constraints	Check each table name in `table_names` for rows with invalid foreign key references. This method is intended to be used in conjunction with `disable_constraint_checking()` and `enable_constraint_checking()`, to determine if rows with invalid references were entered while constraint checks were off.
Method	create_cursor	Create a cursor. Assume that a connection is established.
Method	disable_constraint_checking	Disable foreign key checks, primarily for use in adding rows with forward references. Always return True to indicate constraint checks need to be re-enabled.
Method	enable_constraint_checking	Re-enable foreign key checks after they have been disabled.
Method	get_connection_params	Return a dict of parameters suitable for get_new_connection.
Method	get_database_version	Return a tuple of the database's version.
Method	get_new_connection	Open a connection to the database.
Method	init_connection_state	Initialize the database connection settings.
Method	is_usable	Test if the database connection is usable.

Method	__init__	Undocumented
Method	__repr__	Undocumented
Method	check_database_version_supported	Raise an error if the database version isn't supported by this version of Django.
Method	check_settings	Undocumented
Method	chunked_cursor	Return a cursor that tries to avoid caching in the database (if supported by the database), otherwise return a regular cursor.
Method	clean_savepoints	Reset the counter used to generate unique savepoint ids in this thread.
Method	close	Close the connection to the database.
Method	close_if_health_check_failed	Close existing connection if it fails a health check.
Method	close_if_unusable_or_obsolete	Close the current connection if unrecoverable errors have occurred or if it outlived its maximum age.
Method	commit	Commit a transaction and reset the dirty flag.
Method	connect	Connect to the database. Assume that the connection is closed.
Method	constraint_checks_disabled	Disable foreign key constraint checking.
Method	copy	Return a copy of this connection.
Method	cursor	Create a cursor, opening a connection if necessary.
Method	dec_thread_sharing	Undocumented
Method	ensure_connection	Guarantee that a connection to the database is established.
Method	ensure_timezone	Ensure the connection's timezone is set to `self.timezone_name` and return whether it changed or not.
Method	execute_wrapper	Return a context manager under which the wrapper is applied to suitable database query executions.
Method	get_autocommit	Get the autocommit state.
Method	get_rollback	Get the "needs rollback" flag -- for *advanced use* only.

Method	make_cursor	Create a cursor without debug logging.
Method	make_debug_cursor	Create a cursor that logs all queries in self.queries_log.
Method	on_commit	Undocumented
Method	prepare_database	Hook to do any database check or preparation, generally called before migrating a project or an app.
Method	rollback	Roll back a transaction and reset the dirty flag.
Method	run_and_clear_commit_hooks	Undocumented
Method	savepoint	Create a savepoint inside the current transaction. Return an identifier for the savepoint that will be used for the subsequent rollback or commit. Do nothing if savepoints are not supported.
Method	savepoint_commit	Release a savepoint. Do nothing if savepoints are not supported.
Method	savepoint_rollback	Roll back to a savepoint. Do nothing if savepoints are not supported.
Method	schema_editor	Return a new instance of this backend's SchemaEditor.
Method	set_autocommit	Enable or disable autocommit.
Method	set_rollback	Set or unset the "needs rollback" flag -- for *advanced use* only.
Method	temporary_connection	Context manager that ensures that a connection is established, and if it opened one, closes it to avoid leaving a dangling connection. This is useful for operations outside of the request-response cycle.
Method	validate_no_atomic_block	Raise an error if an atomic block is active.
Method	validate_no_broken_transaction	Undocumented
Method	validate_thread_sharing	Validate that the connection isn't accessed by another thread than the one which originally created it, unless the connection was explicitly authorized to be shared between threads (via the `inc_thread_sharing()` method)...
