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. éNé)ÚcursorsÚ_mysql) ÚWarningÚErrorÚInterfaceErrorÚ DataErrorÚ DatabaseErrorÚOperationalErrorÚIntegrityErrorÚ InternalErrorÚNotSupportedErrorÚProgrammingErrorÚutf8Úcp1252Úkoi8_rÚkoi8_u)Úutf8mb4Úutf8mb3Úlatin1Úkoi8rÚkoi8uz^(\d+)cCs t |¡}|rt| d¡ƒSdS)zšReturns the leading numeric part of a string. >>> numeric_part("20-alpha") 20 >>> numeric_part("foo") >>> numeric_part("16b") 16 rN)Úre_numeric_partÚmatchÚintÚgroup)ÚsÚm©rúJ/var/www/html/kck/venv/lib/python3.10/site-packages/MySQLdb/connections.pyÚ numeric_part#s r cs´eZdZdZejZ‡fdd„Zdd„Zdd„Z dd „Z dd d „Z d d„Z dd„Z dd„Zdd„Zdd„Z‡fdd„Zdd„Zdd„ZeZeZeZeZeZeZeZeZeZeZ‡ZS)Ú Connectionz MySQL Database Connection ObjectcsXddlm}m}ddlm}m}ddlm}| ¡}d|vr%|  d¡|d<d|vr0|  d¡|d<d |vr9|d } n|} i} |   ¡D]\} } t | t ƒrXt | t ƒrX| d d …| | <qA| | | <qA| |d <|  d |j¡} | d d ¡}|  dd¡}|  dd ¡}|  dd¡|_| dd¡}||jO}|  dd¡}|r™||jO}||d<|  dd¡}tƒj|i|¤Ž| |_dd„|   ¡Dƒ|_tdd„| ¡ d¡d d…Dƒƒ|_d|_|sÕ| ¡}| |¡|rá| |¡|r|j|j |j!|j"|j#|j$|j%fD]}||j&|<qôt'|j&|j(<||ƒ‰d‡fdd„ }||jt'<|j)|j*@|_+|j+r'|d ur'| ,|¡g|_-d S) a¹ Create a connection to the database. 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 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. :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)ÚCLIENTÚ FIELD_TYPE)Ú conversionsÚ _bytes_or_str)ÚproxyÚdbÚdatabaseÚpasswdÚpasswordÚconvNÚ cursorclassÚcharsetÚÚ use_unicodeTÚsql_modeÚ binary_prefixFÚ client_flagÚmulti_statementsÚ autocommitcSs"i|] \}}t|ƒtur||“qSr)Útyper)Ú.0ÚkÚvrrrÚ »s"z'Connection.__init__..cSsg|]}t|ƒ‘qSr)r )r6ÚnrrrÚ ¾sz'Connection.__init__..Ú.éÚasciicsˆ | ˆj¡¡S©N)Ústring_literalÚencodeÚencoding)ÚuÚdummy©r'rrÚunicode_literalÛsz,Connection.__init__..unicode_literalr?).ÚMySQLdb.constantsr"r#ÚMySQLdb.convertersr$r%Úweakrefr&ÚcopyÚpopÚitemsÚ isinstancerÚlistÚdefault_cursorÚgetÚ_binary_prefixÚ MULTI_RESULTSÚMULTI_STATEMENTSÚsuperÚ__init__r,ÚencodersÚtupleÚget_server_infoÚsplitÚ_server_versionrBÚcharacter_set_nameÚset_character_setÚ set_sql_modeÚSTRINGÚ VAR_STRINGÚVARCHARÚ TINY_BLOBÚ MEDIUM_BLOBÚ LONG_BLOBÚBLOBÚ converterÚstrÚJSONÚserver_capabilitiesÚ TRANSACTIONSÚ_transactionalr4Úmessages)ÚselfÚargsÚkwargsr"r#r$r%r&Úkwargs2r+Úconv2r7r8r,r-r/r0r2r3r4ÚtrF©Ú __class__rErrU8sxY           ÿ  ù     zConnection.__init__cCs|Sr?r©rlrrrÚ __enter__æszConnection.__enter__cCs | ¡dSr?)Úclose)rlÚexc_typeÚ exc_valueÚ tracebackrrrÚ__exit__és zConnection.__exit__cCs*t|ƒ}| ¡|krtj ||¡dSdSr?)ÚboolÚget_autocommitrÚ connectionr4)rlÚonrrrr4ìs ÿzConnection.autocommitNcCs|p|j|ƒS)zÒ Create a cursor on which queries may be performed.
