Python sqlalchemy 模块，CHAR 实例源码
我们从Python开源项目中，提取了以下28个代码示例，用于说明如何使用sqlalchemy.CHAR。

return dialect.type_descriptor(sql.types.CHAR(32))

'autoincrement': False, 'default': None, 'name': column_name,
'nullable': nullable, 'type': column_type
}
result_column = sa_column_dict_to_column(attributes)
result = {attribute: getattr(result_column, attribute)
for attribute in attributes.keys()}
self.assertEqual(attributes, result)
