多个记录集和活动事务上的 Sybase Ase 15 错误
我们有非常古老的 VB6 应用程序连接到 Sybase 数据库。如今,它们通过 ODBC 连接到 Sybase ASE 15 服务器,使用 Open Client 12 驱动程序运行良好。
有计划升级到 OpenClient 15 驱动程序,在该版本中我收到此错误:
运行时错误“-2147467259(80004005)”
事务不能有多个具有此游标类型的记录集。
更改游标类型、提交事务或关闭记录集之一。
据我了解,在互联网上搜索,问题出在游标上。
在 ODBC 配置管理器的旧驱动程序中,有一个“性能”选项卡,并且光标中有“选择方法”,但在新驱动程序中,此选项卡消失了,我们得到的有关光标的全部内容只是“选择方法”中的一个部分。 常规选项卡名为光标行为,其中我们选中了使用光标选项。
这是一个小代码片段,我可以在其中重现该问题。感谢所有帮助。

We have very old VB6 applications connecting to a Sybase database. Today they are running fine using the Open Client 12 drivers via ODBC connecting to a Sybase ASE 15 servers.
There is a plan on upgrading to the OpenClient 15 drivers and with that version I'm getting this error:
Run-time error '-2147467259(80004005)'
Transaction cannot have multiple recordsets with this cursor type.
Change the cursor type, commit the transaction, or close one of the recordsets.
As I understand searching the internet, the problem is in the Cursors.
In the old drivers in the ODBC configuration manager there was a Performance Tab and we have the Select Method in cursor, but with the new drivers this tab is gone and all we got about cursors is a section in the General tab named Cursor Behavior, in there we have the option Use Cursors checked.
Here is a little code snippet where I can reproduce the problem. All help is appreciated.

最后,Sybase 人员给我们发送了新的驱动程序,解决了问题
in the end the Sybase guys send us a new drivers and that fixed the problem
