Using SSMS, I dropped an index.
In Toad, I right-clicked on the table in Object Explorer, selected Version Control | Update Status, and then selected Version Control | Perspectives. The table is still listed as UpToDate when it should be Modified. The icon by the table name did not change in Object Explorer.
I right-click on the table in Object Explorer and select Version Control | Diff with latest revision and it shows me that the index has been deleted.
I was able to right-click on the table and select Version Control | Commit, but if I didn’t know that this was needed, it would have been missed.
