How to Insert a Python datetime.datetime Object into a MySQL DATE Column?

Inserting a datetime.datetime Object into MySQL

When attempting to insert a datetime.datetime object into a date column of a MySQL table, users may encounter a "TypeError: not all arguments converted during string formatting" error. The cause of this error is the incompatibility between the datetime.datetime object and the placeholder '%s', which is typically used for string values.

To resolve this issue, it is necessary to format the datetime.datetime object into a string that can be recognized by MySQL. The recommended approach is to use the strftime() method of the time module. Here's how you can do it:

import time

now = datetime.datetime(2009, 5, 5)
mysql_date = time.strftime('%Y-%m-%d %H:%M:%S')

cursor.execute("INSERT INTO table
(name, id, datecolumn) VALUES (%s, %s, %s)", ("name", 4, mysql_date))

By formatting the datetime.datetime object with strftime(), the resulting string is compatible with the MySQL date column. The strftime() method accepts a specific format string that specifies the desired output format of the date and time. In this example, '%Y-%m-%d %H:%M:%S' represents the format: year-month-day hour:minute:second. You can adjust this format string to suit your specific requirements.

This modified approach should allow you to successfully insert datetime.datetime objects into your MySQL table without any further errors.
