SQLAlchemy Python的ORM框架

SQLAlchemy是Python编程语言下的一款开源软件。提供了SQL工具包及对象关系映射（ORM）工具，使用MIT许可证发行。

SQLAlchemy 1.1.10 版本现在可用。

1.1.10 版本包含一系列针对指定行为的修复：

orm

• [orm] [bug] Fixed bug where a cascade such as “delete-orphan” (but others as well) would fail to locate an object linked to a relationship that itself is local to a subclass in an inheritance relationship, thus causing the operation to not take place.¶

postgresql

• [postgresql] [bug] Added “autocommit” support for GRANT, REVOKE keywords. Pull request courtesy Jacob Hayes.

mysql

• [mysql] [bug] Removed an ancient and unnecessary intercept of the UTC_TIMESTAMP MySQL function, which was getting in the way of using it with a parameter.

• [mysql] [bug] Fixed bug in MySQL dialect regarding rendering of table options in conjunction with PARTITION options when rendering CREATE TABLE. The PARTITION related options need to follow the table options, whereas previously this ordering was not enforced.

oracle

• [oracle] [bug] Fixed bug in cx_Oracle dialect where version string parsing would fail for cx_Oracle version 6.0b1 due to the “b” character. Version string parsing is now via a regexp rather than a simple split.

misc

• [bug] [ext] Protected against testing “None” as a class in the case where declarative classes are being garbage collected and new automap prepare() operations are taking place concurrently, very infrequently hitting a weakref that has not been fully acted upon after gc.
