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: sets ``MYSQL_OPT_LOCAL_INFILE`` in ``mysql_options()`` enabling LOAD LOCAL INFILE from any path; zero disables; :param str local_infile_dir: sets ``MYSQL_OPT_LOAD_DATA_LOCAL_DIR`` in ``mysql_options()`` enabling LOAD LOCAL INFILE from any path; if ``local_infile`` is set to ``True`` then this is ignored; supported for mysql version >= 8.0.21 :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 autocommitcFi|]\}}t|tu||S)typer).0kvs r z'Connection.__init__..s9   1Awwc!! q!!!r"c,g|]}t|Sr:)r!)r<ns r z'Connection.__init__..s L L L\!__ L L Lr".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_transactionalr8messages)selfargskwargsr&r'r(r)kwargs2r.conv2r=r>r/r0r2r3r4r6r7r8t __class__s r rTzConnection.__init__8sZ 98888888AAAAAAAA++-- 7??")++d"3"3GJ  w  ")++h"7"7GJ  V  &>DDDJJLL  DAq!S!! jD&9&9 QQQ4aakk-1DEE ++i,,KK R00 kk-66 ;;z2..%kk/5AAjj22 v++ ";;'94@@  3 62 2K!, [[u55 d.g...$*'***&       % L Ld&:&:&<&<&B&B3&G&G&K L L L     0--//G w 222  (   h ' ' '  2!%"$&$ 2 2%2q!!/2DN:? +"69LL   ,% +++ r"Nr1 c J|r|sd}||_||_||_||_dS)zset some attributes for otel localhostN)hostuserr+r*)rlrvrwr-r+port unix_socketrns r rRzConnection._set_attributess8  t D    r"c|SNr:rls r __enter__zConnection.__enter__s r"c.|dSr{)close)rlexc_type exc_value tracebacks r __exit__zConnection.__exit__ s r"ct|}||kr"tj||dSdSr{)boolget_autocommitr connectionr8)rlons r r8zConnection.autocommit sK "XX    B & &   ( (r 2 2 2 2 2 ' &r"c&|p|j|S)z Create a cursor on which queries may be performed.
