I was successful in getting Oracle's MySQL connector for python working with SQLAlchemy on Python 3.3. Your connection string needs to start with "mysql+mysqlconnector://...". After I changed my connection string everything (well, simple things) started working. 

The MySQL connector docs can be found here: <a href="https://dev.mysql.com/doc/connector-python/en/" rel="noreferrer">https://dev.mysql.com/doc/connector-python/en/</a>

The package is up on PyPi: <a href="https://pypi.org/project/mysql-connector-python/" rel="noreferrer">https://pypi.org/project/mysql-connector-python/</a>

Here are the SQLAlchemy docs about using the Python connector: <a href="http://docs.sqlalchemy.org/en/latest/dialects/mysql.html#module-sqlalchemy.dialects.mysql.mysqlconnector" rel="noreferrer">http://docs.sqlalchemy.org/en/latest/dialects/mysql.html#module-sqlalchemy.dialects.mysql.mysqlconnector</a>

I've gotten oursql + SQLAlchemy 0.8.1 + Python 3.3 to work. Building off of LukeCarrier's port, I modified oursql.c to use the correct import levels, and it worked! Try this, and be sure to follow the readme:

<a href="https://github.com/clintron/py3k-oursql" rel="nofollow">https://github.com/clintron/py3k-oursql</a>

You may also need to have the latest version of Cython.

blocks|key|2089537|text|正如@Brad所建议的，我尝试了Oracle的连接，但不幸的是，它非常慢，比我在Python2上使用的与MySQL-Python的“真实”SQLAlchemy连接要慢得多。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2089538|在检查了SQLAlchemy自己之后，|2089539|http://docs.sqlalchemy.org/en/latest/dialects/mysql.html#module-sqlalchemy.dialects.mysql.mysqldb|2089540|要在Python3上使用MySQL-Python，他们推荐一个叉子，mysqlclient，|2089541|https://github.com/PyMySQL/mysqlclient-python|2089542|它可以通过pip与pip+install+mysqlclient一起使用，但几乎可以肯定的是，您需要完成其他步骤才能开始设置它。不过，在那之后，我看到的性能回到了我习惯的水平，比Oracle的连接器快了大约5倍。|2089543|entityMap|0|LINK|mutability|MUTABLE|url|1^0|1G|C|1X|A|0|0|0|2P|0|0|C|C|Y|B|0|0|19|1|0|9|N|0^^$0|@$1|2|3|4|5|6|7|X|8|@$9|Y|A|Z|B|C]|$9|10|A|11|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|12|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|13|8|@]|D|@$9|14|A|15|1|16]]|E|$]]|$1|J|3|K|5|6|7|17|8|@$9|18|A|19|B|C]|$9|1A|A|1B|B|C]]|D|@]|E|$]]|$1|L|3|M|5|6|7|1C|8|@]|D|@$9|1D|A|1E|1|1F]]|E|$]]|$1|N|3|O|5|6|7|1G|8|@$9|1H|A|1I|B|C]]|D|@]|E|$]]|$1|P|3|-4|5|6|7|1J|8|@]|D|@]|E|$]]]|Q|$R|$5|S|T|U|E|$V|I]]|W|$5|S|T|U|E|$V|M]]]]

I tried Oracle's connection, as suggested by @Brad Campbell, but unfortunately it was extremely slow, much slower than the "real" <code>MySQL-Python</code> connection I had been using with <code>SQLAlchemy</code> on Python 2.

After checking SQLAlchemy themselves,

<a href="http://docs.sqlalchemy.org/en/latest/dialects/mysql.html#module-sqlalchemy.dialects.mysql.mysqldb" rel="nofollow noreferrer">http://docs.sqlalchemy.org/en/latest/dialects/mysql.html#module-sqlalchemy.dialects.mysql.mysqldb</a>

To use <code>MySQL-Python</code> on Python 3, they recommend a fork of it, <code>mysqlclient</code>,

<a href="https://github.com/PyMySQL/mysqlclient-python" rel="nofollow noreferrer">https://github.com/PyMySQL/mysqlclient-python</a>

It is available via pip with <code>pip install mysqlclient</code>, but there are almost certainly other steps you'll need to do to set it up initially. After that though, I was seeing the performance go back to what I was used to, which was about 5x faster than with Oracle's connector.

Currently:

<ul>
<li>SQLAlchemy installed and working (or at least import v0.8.0b2)</li>
<li>Mysql (v5.5.16)</li>
<li>Distribute (0.6.34)</li>
<li>Oracle mysql-python connector </li>
<li>Python 3.2</li>
<li>Windows 7 32/64 (note that I installed Python 32bits)</li>
</ul>

The problem is that MySQLdb or Oursql is required and I didn't managed to get any of them working.

Found <a href="https://github.com/davispuh/MySQL-for-Python-3" rel="noreferrer">this</a> but didn't manage to get it working neither.

Edit: If you are aware of an other orm that works with Python3, I'm interested.
