Refresh SQL Server Native Client after renaming a Field?

Hello,

I renamed a Field of a FeatureClass in an ArcSDE with the IClassSchemaEdit4.AlterFieldName Method.
This works fine, but as soon as I create a Cursor to iterate the FeatureClass I get an SQL Server Native Client Error, which can't find the old(!!) Fieldname in the Database.
m_pCursor = pFeatureClass.Search(Nothing, False)


But if i look for the renamed Field in the FeatureClass everything is fine --> I can't find the old fieldname and the new one is there.

I have no idea why the Native Client is looking for the old Fieldname? Do I have to refresh the Client somehow?

If I restart my application or look at the FeatureClass with ArcCatalog everything works fine.

Any idea whats going on with the Microsoft SQL Server Native Client 10.0?

Thanks
Mickey

We're currently encountering a similar issue. Have you ever found a resolution to this problem?

You have to reconnect to the Workspace, and look for the Feature-Class, again. Then only use the new FC-Object and dispose the old one.

Hi Mickey, thanks for your answer. While this would resolve the problem, it does not work for us in a performance critical environment where reconnecting to the workspace is not an option. We have, while exploring workarounds, found a way to avoid our original problem. Thanks!
