当您调用 JetUpdate() 时，第三个参数是“书签”。JetUpdate() 完成后，您可以使用
JetGotoBookmark() - http://msdn.microsoft.com/en-us/library/ms683554(EXCHG.10).aspx

Note that it is also possible to retrieve the autoincrement value before calling JetUpdate, because the value is assigned when JetUpdate is called. You need to use the JET_bitRetrieveCopy option with JetRetrieveColumn.
For an example in managed code see the "How Do I Retrieve an Auto-Increment Column Value?" section on this page.
