This method sets the character set and collation to be used for

name of a character set as a string, or the numerical equivalent
|
as defined in constants.CharacterSet.
|
|
When the collation is not given, the default will be looked up and

used.
|

For example, the following will set the collation for the latin1

|
|
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.
|
|
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')
|
|
Raises ProgrammingError when a transaction is already in progress
|
and when ValueError when isolation_level specifies an Unknown
|
level.

|
|
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.
|
This method takes two arguments user_variables and session_variables
|
which are dictionaries.
|
|
Raises OperationalError if not connected, InternalError if there are

unread results and InterfaceError on errors.

|
|
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.
|
|
Coding Example:
|
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 = (5,5,0) # 0 is to hold pprod
|
cursor.callproc('multiply', args)
|
print(cursor.fetchone())
|
|
Does not return a value, but a result set will be
|
available when the CALL-statement execute successfully.
|
Raises exceptions when something is wrong.

|
|
Executes the given operation 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,))
|
|
The multi argument should be set to True when executing multiple
|
statements in one operation. If not set and multiple results are
|
found, an InterfaceError will be raised.
|
|
If warnings where generated, and connection.get_warnings is True, then
|
self._warnings will be a list containing these warnings.
|
|
Returns an iterator when multi is True, otherwise None.
|
Nre )rd r ró r re re rf rG s zMySQLCursorAbstract.executez.Sequence[Union[Sequence[Any], Dict[str, Any]]])r Ú
|
seq_paramsr6 c C s dS )aÇ Execute the given operation multiple times
|
|
The executemany() method will execute the operation iterating
|
over the list of parameters in seq_params.
|
|
Example: Inserting 3 new employees and their phone number
|
|
data = [
|
('Jane','555-001'),
|
('Joe', '555-001'),
|
('John', '555-003')
|
]
|
stmt = "INSERT INTO employees (name, phone) VALUES ('%s','%s')"
|
cursor.executemany(stmt, data)
|
|
INSERT statements are optimized by batching the data, that is
|
using the MySQL multiple rows syntax.
|
|
Results are discarded. If they are needed, consider looping over
|
data using the execute() method.

such as a SELECT, or affected rows when executing DML statements

like INSERT or UPDATE.
|
|
Note that for non-buffered cursors it is impossible to know the

number of rows produced before having fetched them all. For those,

the number of rows will be -1 right after execution, and

incremented when fetching rows.
