Try using <code>now.date()</code> to get a <code>Date</code> object rather than a <code>DateTime</code>.

If that doesn't work, then converting that to a string should work:

<pre><code>now = datetime.datetime(2009,5,5)
str_now = now.date().isoformat()
cursor.execute('INSERT INTO table (name, id, datecolumn) VALUES (%s,%s,%s)', ('name',4,str_now))

What database are you connecting to? I know Oracle can be picky about date formats and likes <a href="http://en.wikipedia.org/wiki/ISO_8601" rel="nofollow noreferrer">ISO&nbsp;8601</a> format.

**Note: Oops, I just read you are on MySQL. Just format the date and try it as a separate direct SQL call to test.

In Python, you can get an ISO date like

<pre><code>now.isoformat()
</code></pre>

For instance, Oracle likes dates like

<pre><code>insert into x values(99, '31-may-09');
</code></pre>

Depending on your database, if it is Oracle you might need to TO_DATE it:

<pre><code>insert into x
values(99, to_date('2009/05/31:12:00:00AM', 'yyyy/mm/dd:hh:mi:ssam'));
</code></pre>

The general usage of TO_DATE is:

<pre><code>TO_DATE(&lt;string&gt;, '&lt;format&gt;')
</code></pre>

If using another database (I saw the cursor and thought Oracle; I could be wrong) then check their date format tools. For MySQL it is DATE_FORMAT() and SQL&nbsp;Server it is CONVERT.

Also using a tool like <a href="https://en.wikipedia.org/wiki/SQLAlchemy" rel="nofollow noreferrer">SQLAlchemy</a> will remove differences like these and make your life easy.

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

With regards to the format, I had success with the above command (which includes the milliseconds) and with:

<pre><code>now.strftime('%Y-%m-%d %H:%M:%S')

Hope this helps.

<blockquote>
 MySQL recognizes DATETIME and TIMESTAMP values in these formats:
 
 As a string in either 'YYYY-MM-DD HH:MM:SS' or 'YY-MM-DD HH:MM:SS'
 format. A “relaxed” syntax is permitted here, too: Any punctuation
 character may be used as the delimiter between date parts or time
 parts. For example, '2012-12-31 11:30:45', '2012^12^31 11+30+45',
 '2012/12/31 11*30*45', and '2012@12@31 11^30^45' are equivalent.
 
 The only delimiter recognized between a date and time part and a
 fractional seconds part is the decimal point.
 
 The date and time parts can be separated by T rather than a space. For
 example, '2012-12-31 11:30:45' '2012-12-31T11:30:45' are equivalent.
 
 As a string with no delimiters in either 'YYYYMMDDHHMMSS' or
 'YYMMDDHHMMSS' format, provided that the string makes sense as a date.
 For example, '20070523091528' and '070523091528' are interpreted as
 '2007-05-23 09:15:28', but '071122129015' is illegal (it has a
 nonsensical minute part) and becomes '0000-00-00 00:00:00'.
 
 As a number in either YYYYMMDDHHMMSS or YYMMDDHHMMSS format, provided
 that the number makes sense as a date. For example, 19830905132800 and
 830905132800 are interpreted as '1983-09-05 13:28:00'.
