The argument `attempts` should be the number of times a reconnect is tried. The `delay` argument is the number of seconds to wait between each retry. You may want to set the number of attempts higher and use delay when you expect the MySQL server to be down for maintenance or when you expect the network to be temporary unavailable.

NrQ )r� r� r� r� s rS �pingz MySQLConnectionAbstract.ping� r rR c � � y)a� Commits current transaction. This method is part of PEP 249 - Python Database API Specification v2.0. This method sends a COMMIT statement to the MySQL server, committing the current transaction. Since by default Connector/Python does not autocommit. It is important to call this method after every transaction that modifies data for tables that use transactional storage engines. Examples: ``` >>> stmt = "INSERT INTO employees (first_name) VALUES (%s), (%s)" >>> cursor.execute(stmt, ('Jane', 'Mary')) >>> cnx.commit() ``` NrQ r� s rS �commitz MySQLConnectionAbstract.commit� r rR c � � y)a^ Instantiates and returns a cursor. By default, `MySQLCursor` or `CMySQLCursor` is returned. Depending on the options while connecting, a buffered and/or raw cursor is instantiated instead. Also depending upon the cursor options, rows can be returned as a dictionary or a tuple. Dictionary based cursors are available with buffered output but not raw. It is possible to also give a custom cursor through the `cursor_class` parameter, but it needs to be a subclass of `mysql.connector.cursor.MySQLCursor` or `mysql.connector.cursor_cext.CMySQLCursor` according to the type of connection that's being used. **NOTE: The parameters read and write timeouts in cursors are unsupported for C-Extension.** Args: buffered: If `True`, the cursor fetches all rows from the server after an operation is executed. This is useful when queries return small result sets. raw: If `True`, the cursor skips the conversion from MySQL data types to Python types when fetching rows. A raw cursor is usually used to get better performance or when you want to do the conversion yourself. prepared: If `True`, the cursor is used for executing prepared statements. cursor_class: It can be used to pass a class to use for instantiating a new cursor. It must be a subclass of `cursor.MySQLCursor` or `cursor_cext.CMySQLCursor` according to the type of connection that's being used. dictionary: If `True`, the cursor returns rows as dictionaries. read_timeout: A positive integer representing timeout in seconds for each attempt to read any data from the server. write_timeout: A positive integer representing timeout in seconds for each attempt to send any data to the server. Returns: cursor: A cursor object. Raises: ProgrammingError: When `cursor_class` is not a subclass of `MySQLCursorAbstract`. ValueError: When cursor is not available.

Sends a ROLLBACK statement to the MySQL server, undoing all data changes from the current transaction. By default, Connector/Python does not autocommit, so it is possible to cancel transactions when using transactional storage engines such as `InnoDB`.

This method explicitly starts a transaction sending the START TRANSACTION statement to the MySQL server. You can optionally set whether there should be a consistent snapshot, which isolation level you need or which access mode i.e. READ ONLY or READ WRITE. Args: consistent_snapshot: If `True`, Connector/Python sends WITH CONSISTENT SNAPSHOT with the statement. MySQL ignores this for isolation levels for which that option does not apply. isolation_level: Permitted values are 'READ UNCOMMITTED', 'READ COMMITTED', 'REPEATABLE READ', and 'SERIALIZABLE'. If the value is `None`, no isolation level is sent, so the default level applies. readonly: Can be `True` to start the transaction in READ ONLY mode or `False` to start it in READ WRITE mode. If readonly is omitted, the server's default access mode is used. Raises: ProgrammingError: When a transaction is already in progress and when `ValueError` when `isolation_level` specifies an Unknown level. Examples: For example, to start a transaction with isolation level `SERIALIZABLE`, you would do the following: ``` >>> cnx = mysql.connector.connect(...) >>> cnx.start_transaction(isolation_level='SERIALIZABLE') ``` z Transaction already in progressr� � )zREAD UNCOMMITTEDzREAD COMMITTEDzREPEATABLE READ� SERIALIZABLEzUnknown isolation level "�"z SET TRANSACTION ISOLATION LEVEL N)� � r zMySQL server version z does not support this featurez READ ONLYz READ WRITEzSET TRANSACTION zSTART TRANSACTIONz WITH CONSISTENT SNAPSHOT) r� r1 r� rK r� rJ r� rh r )r� �consistent_snapshot�isolation_level�readonly�level�levels� access_moder� s rS �start_transactionz)MySQLConnectionAbstract.start_transaction s� � �N � � �"�#D�E� E� �#�)�)�+�3�3�C��=�C�C�E�E��F� �F�"� �#<�_�<M�Q�!O�P�P� � � �"B�5�'� J� K� � ��#�#�i�/� �+�D�,@�,@�+A� B+� +�� � � )� � *� � � � �"2�;�-� @� A�#�� � �0� 0�E� ���u� rR c � � y)a� Clears the current active session. This method resets the session state, if the MySQL server is 5.7.3 or later active session will be reset without re-authenticating. For other server versions session will be reset by re-authenticating. It is possible to provide a sequence of variables and their values to be set after clearing the session. This is possible for both user defined variables and session variables. Args: user_variables: User variables map. session_variables: System variables map. Raises: OperationalError: If not connected. InternalError: If there are unread results and InterfaceError on errors. Examples: ``` >>> user_variables = {'var1': '1', 'var2': '10'} >>> session_variables = {'wait_timeout': 100000, 'sql_mode': 'TRADITIONAL'} >>> cnx.reset_session(user_variables, session_variables) ``` NrQ )r� �user_variables�session_variabless rS � reset_sessionz%MySQLConnectionAbstract.reset_sessiong r rR r c � � || _ y)�� Sets the converter class to be used.

This method sends the query to the MySQL server and returns the result. To **send multiple statements, use the `cmd_query_iter()` method instead**. The returned dictionary contains information depending on what kind of query was executed. If the query is a `SELECT` statement, the result contains information about columns. Other statements return a dictionary containing OK or EOF packet information. Errors received from the MySQL server are raised as exceptions. **Arguments `raw`, `buffered` and `raw_as_string` are only meaningful for `C-ext` connections**. Args: query: Statement to be executed. raw: If `True`, the cursor skips the conversion from MySQL data types to Python types when fetching rows. A raw cursor is usually used to get better performance or when you want to do the conversion yourself. If not provided, take its value from the MySQL instance. buffered: If `True`, the cursor fetches all rows from the server after an operation is executed. This is useful when queries return small result sets. raw_as_string: Is a special argument for Python v2 and returns `str` instead of `bytearray`.

Similar to the `cmd_query()` method, but instead returns a generator object to iterate through results. It sends the statements to the MySQL server and through the iterator you can get the results. Use `cmd_query_iter()` when sending multiple statements, and separate the statements with semicolons. Args: statements: Statements to be executed separated with semicolons. Returns: generator: Generator object with `Result` or `OK packet` information. Examples: The following example shows how to iterate through the results after sending multiple statements: ``` >>> statement = 'SELECT 1; INSERT INTO t1 VALUES (); SELECT 2' >>> for result in cnx.cmd_query_iter(statement): >>> if 'columns' in result: >>> columns = result['columns'] >>> rows = cnx.get_rows() >>> else: >>> # do something useful with INSERT result ``` NrQ )r� � statementsrU s rS �cmd_query_iterz&MySQLConnectionAbstract.cmd_query_iter r rR c � � y)a� Send the Refresh command to the MySQL server.

This method permits the session state to be cleared without reauthenticating. For MySQL servers older than 5.7.3 (when `COM_RESET_CONNECTION` was introduced) , the `reset_session()` method can be used instead - that method resets the session state by reauthenticating, which is more expensive. This method was added in Connector/Python 1.2.1. Returns: `True` for a successful reset otherwise `False`.

The arguments will be set during this session, meaning they will be called like _<procname>__arg<nr> where <nr> is an enumeration (+1) of the arguments. Args: procname: The stored procedure name. args: Sequence of parameters - it must contain one entry for each argument that the procedure expects. Returns: Does not return a value, but a result set will be available when the CALL-statement executes successfully. `callproc()` returns a modified copy of the input sequence. `Input` parameters are left untouched. `Output` and `input/output` parameters may be replaced with new values. Result sets produced by the stored procedure are automatically fetched and stored as `MySQLCursorBuffered` instances. The value returned (if any) is a `Dict` when cursor's subclass is `MySQLCursorDict`, else a `Tuple` (RowType). Raises: InterfaceError: When something is wrong Examples: 1) Defining the Stored Routine in MySQL: ``` CREATE PROCEDURE multiply(IN pFac1 INT, IN pFac2 INT, OUT pProd INT) BEGIN SET pProd := pFac1 * pFac2; END; ``` 2) Executing in Python: ``` >>> args = (5, 6, 0) # 0 is to hold value of the OUT parameter pProd >>> cursor.callproc('multiply', args) ('5', '6', 30L) ``` References: [1]: https://dev.mysql.com/doc/connector-python/en/ connector-python-api-mysqlcursor-callproc.html NrQ )r� �procname�argss rS �callprocz MySQLCursorAbstract.callproc r rR c � � y)a= Close the cursor. Use close() when you are done using a cursor. This method closes the cursor, resets all results, and ensures that the cursor object has no reference to its original connection object. This method is part of PEP 249 - Python Database API Specification v2.0. NrQ r� s rS r� zMySQLCursorAbstract.closeB r rR c � � y)a> Executes the given operation (a MySQL script) substituting any markers with the given parameters. For example, getting all rows where id is 5: ``` cursor.execute("SELECT * FROM t1 WHERE id = %s", (5,)) ``` If you want each single statement in the script to be related to its corresponding result set, you should enable the `map_results` switch - see workflow example below. If the given script uses `DELIMITER` statements (which are not recognized by MySQL Server), the connector will parse such statements to remove them from the script and substitute delimiters as needed. This pre-processing may cause a performance hit when using long scripts. Note that when enabling `map_results`, the script is expected to use `DELIMITER` statements in order to split the script into multiple query strings. The following characters are currently not supported by the connector in `DELIMITER` statements: `"`, `'`, #`, `/*` and `*/`. If warnings were generated, and `connection.get_warnings` is `True`, then `self.warnings` will be a list containing these warnings. Args: operation: Operation to be executed - it can be a single or a multi statement. params: The parameters found in the tuple or dictionary params are bound to the variables in the operation. Specify variables using `%s` or `%(name)s` parameter style (that is, using format or pyformat style). map_results: It is `False` by default. If `True`, it allows you to know what statement caused what result set - see workflow example below. Only relevant when working with multi statements. Returns: `None`. Example (basic usage): The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation) result_set = cur.fetchall() # do something with result set ... while cur.nextset(): result_set = cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected. Example (statement-result mapping): The following example runs many single statements in a single go and loads the corresponding result sets sequentially. Additionally, each result set gets related to the statement that caused it: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation, map_results=True) # statement 1 is `SET @a=1, @b='2024-02-01'`, # result set from statement 1 is `[]` - aka, an empty set. result_set, statement = cur.fetchall(), cur.statement # do something with result set ... # 1st call to `nextset()` will laod the result set from statement 2, # statement 2 is `SELECT @a, LENGTH('hello'), @b`, # result set from statement 2 is `[(1, 5, '2024-02-01')]`. # # 2nd call to `nextset()` will laod the result set from statement 3, # statement 3 is `SELECT @@version`, # result set from statement 3 is `[('9.0.0-labs-mrs-8',)]`. # # 3rd call to `nextset()` will return `None` as there are no more sets, # leading to the end of the consumption process of result sets. while cur.nextset(): result_set, statement = cur.fetchall(), cur.statement # do something with result set ... ``` In case the mapping is disabled (`map_results=False`), all result sets get related to the same statement, which is the one provided when calling `execute()`. In other words, the property `statement` will not change as result sets are consumed, which contrasts with the case in which the mapping is enabled. Note that we offer a new fetch-related API command which can be leveraged as a shortcut for consuming result sets - it is equivalent to the previous workflow. ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation, map_results=True) for statement, result_set in cur.fetchsets(): # do something with result set ``` NrQ )r� � operation�params� map_resultss rS �executezMySQLCursorAbstract.executeM r rR c � � y)a� Executes the given operation multiple times. The `executemany()` method will execute the operation iterating over the list of parameters in `seq_params`. `INSERT` statements are optimized by batching the data, that is using the MySQL multiple rows syntax. Args: operation: Operation to be executed. seq_params: Parameters to be used when executing the operation. Returns: Results are discarded. If they are needed, consider looping over data using the `execute()` method. Examples: An optimization is applied for inserts: The data values given by the parameter sequences are batched using multiple-row syntax. The following example inserts three records: ``` >>> data = [ >>> ('Jane', date(2005, 2, 12)), >>> ('Joe', date(2006, 5, 23)), >>> ('John', date(2010, 10, 3)), >>> ] >>> stmt = "INSERT INTO employees (first_name, hire_date) VALUES (%s, %s)" >>> cursor.executemany(stmt, data) ``` For the preceding example, the INSERT statement sent to MySQL is: ``` >>> INSERT INTO employees (first_name, hire_date) >>> VALUES ('Jane', '2005-02-12'), ('Joe', '2006-05-23'), ('John', '2010-10-03') ``` NrQ )r� r� � seq_paramss rS � executemanyz MySQLCursorAbstract.executemany� r rR c � � y)a Retrieves next row of a query result set Returns: If the cursor's subclass is `MySQLCursorDict`, a dictionaries is returned, otherwise a tuple (RowType). `None` is returned when there aren't results to be read.

Args: size: The number of rows returned can be specified using the size argument, which is one by default.

NrQ )r� �sizes rS � fetchmanyz MySQLCursorAbstract.fetchmany r rR c � � y)a� Fetches all (or all remaining) rows of a query result set.

Returns: A 2-tuple; the first element is the statement that caused the result set, and the second is the result set itself. This method is used as part of the multi statement execution workflow - see example below. Example: Consider the following example where multiple statements are executed in one go: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation, map_results=True) result_set, statement = cur.fetchall(), cur.statement # do something with result set ... while cur.nextset(): result_set, statement = cur.fetchall(), cur.statement # do something with result set ... ``` In this case, as an alternative to loading the result sets with `nextset()` in combination with a `while` loop, you can use `fetchsets()` which is equivalent to the previous approach: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation) for statement, result_set in cur.fetchsets(): # do something with result set ``` N)r� rP r� r/ �nextset)r� �statement_cached� result_sets rS � fetchsetsz MySQLCursorAbstract.fetchsets2 s� � �� �r ���%�%� #�~�~� � � � � � �J� #� 4� 4�D�N�N�:J� �� � �l�l�n� � !�]�]�_� � #'�"8�"8����>N��� � �l�l�n�� � ��J� �� "� � � � �sQ �C �B �.C � B/ �-.C � C � B,�)C �+B,�,C �/ B=�:C �<B=�=C c � � y)a Returns an iterator (of MySQLCursorAbstract subclass instances) for stored results. This method returns an iterator over results which are stored when callproc() is called. The iterator will provide `MySQLCursorBuffered` instances.

This method is used as part of the multi statement execution workflow - see example below. Returns: It returns `None` if there are no more sets. Otherwise, it returns `True` and subsequent calls to the `fetch*()` methods will return rows from the next result set. Example: The following example runs many single statements in a single go and loads the corresponding result sets sequentially: ``` sql_operation = ''' SET @a=1, @b='2024-02-01'; SELECT @a, LENGTH('hello'), @b; SELECT @@version; ''' with cnx.cursor() as cur: cur.execute(sql_operation) result_set = cur.fetchall() # do something with result set ... while cur.nextset(): result_set = cur.fetchall() # do something with result set ... ``` In case the operation is a single statement, you may skip the looping section as no more result sets are to be expected.
