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. Nr, )r* � operation�params�multir, r, r- r� � s zMySQLCursorAbstract.executec C s dS )a� 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.

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.
