Others are unlikely. However, you might want to make your own subclasses. In most cases, you will probably override Connection.default_cursor with a non-standard Cursor class.

It is strongly recommended that you only use keyword parameters. Consult the MySQL C API documentation for more information. :param str host: host to connect :param str user: user to connect as :param str password: password to use :param str passwd: alias of password (deprecated) :param str database: database to use :param str db: alias of database (deprecated) :param int port: TCP/IP port to connect to :param str unix_socket: location of unix_socket to use :param dict conv: conversion dictionary, see MySQLdb.converters :param int connect_timeout: number of seconds to wait before the connection attempt fails. :param bool compress: if set, compression is enabled :param str named_pipe: if set, a named pipe is used to connect (Windows only) :param str init_command: command which is run once the connection is created :param str read_default_file: file from which default client values are read :param str read_default_group: configuration group to use from the default file :param type cursorclass: class object, used to create cursors (keyword only) :param bool use_unicode: If True, text-like columns are returned as unicode objects using the connection's character set. Otherwise, text-like columns are returned as bytes. Unicode objects will always be encoded to the connection's character set regardless of this setting. Default to True. :param str charset: If supplied, the connection character set will be changed to this character set. :param str collation: If ``charset`` and ``collation`` are both supplied, the character set and collation for the current connection will be set. If omitted, empty string, or None, the default collation for the ``charset`` is implied. :param str auth_plugin: If supplied, the connection default authentication plugin will be changed to this value. Example values: `mysql_native_password` or `caching_sha2_password` :param str sql_mode: If supplied, the session SQL mode will be changed to this setting. For more details and legal values, see the MySQL documentation. :param int client_flag: flags to use or 0 (see MySQL docs or constants/CLIENTS.py) :param bool multi_statements: If True, enable multi statements for clients >= 4.1. Defaults to True. :param str ssl_mode: specify the security settings for connection to the server; see the MySQL documentation for more details (mysql_option(), MYSQL_OPT_SSL_MODE). Only one of 'DISABLED', 'PREFERRED', 'REQUIRED', 'VERIFY_CA', 'VERIFY_IDENTITY' can be specified. :param dict ssl: dictionary or mapping contains SSL connection parameters; see the MySQL documentation for more details (mysql_ssl_set()). If this is set, and the client does not support SSL, NotSupportedError will be raised. Since mysqlclient 2.2.4, ssl=True is alias of ssl_mode=REQUIRED for better compatibility with PyMySQL and MariaDB. :param str server_public_key_path: specify the path to a file RSA public key file for caching_sha2_password. See https://dev.mysql.com/doc/refman/9.0/en/caching-sha2-pluggable-authentication.html :param bool local_infile: enables LOAD LOCAL INFILE; zero disables :param bool autocommit: If False (default), autocommit is disabled. If True, autocommit is enabled. If None, autocommit isn't set and server default is used. :param bool binary_prefix: If set, the '_binary' prefix will be used for raw byte query arguments (e.g. Binary). This is disabled by default. There are a number of undocumented, non-standard methods. See the documentation for the MySQL C API for some hints on what they do. r)CLIENT FIELD_TYPE) conversions _bytes_or_strdbdatabasepasswdpasswordconvN cursorclasscharset collation use_unicodeTsql_mode binary_prefixF client_flagmulti_statements autocommitcSs"i|] \}}t|tur||qSr)typer).0kvrrr s  z'Connection.__init__..cSsg|]}t|qSr)r )r6nrrr sz'Connection.__init__...ascii)-MySQLdb.constantsr"r#MySQLdb.convertersr$r%copypopitems isinstancerlistdefault_cursorget_binary_prefix MULTI_RESULTSMULTI_STATEMENTS_set_attributessuper__init__r+encoderstupleget_server_infosplit_server_versionencodingcharacter_set_nameset_character_set set_sql_modeSTRING VAR_STRINGVARCHAR TINY_BLOB MEDIUM_BLOB LONG_BLOBBLOB converterstrJSONserver_capabilities TRANSACTIONS_transactionalr4messages)selfargskwargsr"r#r$r%kwargs2r*conv2r7r8r+r,r.r/r0r2r3r4t __class__rrrM8sxg                 zConnection.__init__Nr- cKs(|r|sd}||_||_||_||_dS)zset some attributes for otel localhostN)hostuserr'r&)rerorpr)r'port unix_socketrgrrrrKs  zConnection._set_attributescCs|SNrrerrr __enter__szConnection.__enter__cCs |dSrs)close)reexc_type exc_value tracebackrrr__exit__s zConnection.__exit__cCs*t|}||krtj||dSdSrs)boolget_autocommitr connectionr4)reonrrrr4s zConnection.autocommitcCs|p|j|S)z Create a cursor on which queries may be performed.
