Learn about the Python MySQL cursor object and how to use it for executing SQL commands and retrieving data from a MySQL database.

The following example shows how to query data using a cursor created using the connection's cursor() method. The data returned is formatted and printed on the console.

Replacing cursor_class= with dictionary=True works in v2. It's not the important problem, but it looks like you've got extra quotes in your code (e.g., it should be .connect(database='bananas')). A possible solution involves subclassing the MySQLCursor class like this: def _row_to_python(self, rowdata, desc=None):

insert_stmt = ( "INSERT INTO employees (emp_no, first_name, last_name, hire_date) " "VALUES (%s, %s, %s, %s)" ) data = (2, 'Jane', 'Doe', datetime.date(2012, 3, 23)) cursor.execute(insert_stmt, data) select_stmt = "SELECT * FROM employees WHERE emp_no = %(emp_no)s" cursor.execute(select_stmt, { 'emp_no': 2 })
