I created a MSAccess application with the forms in one db (front end) and the tables in another db (back end). The network admin migrated the back end to SQL Server. With a few minor changes (changing -1 to 1 in queries, etc.) the migration seemed to go pretty smoothly and everything works fine except....
The MSAccess backend used to lock records when someone was editing them. The status of the record was indicated in the record selector on each form, a right pointing arrow to indicate the record was free, a pencil with three dots indicating the record was locked by the current user, and a circle with a diagonal line to indicate the record was locked by another user. When 2 users attempted to simultaneously edit a record, the first user got the lock on the record. The second user received a message as soon as they attempted to edit the locked record to the effect that the record was locked.
Now (since the migration to SQL Server) the record selectors no longer give any indication as to the locking status of the records. When 2 users attempt to simultaneously edit a record, both are able to enter information in their forms, but when the second user attempts to save the record they receive the following message:
This record has been changed by another user since you started editing it. If you save the record, you will overwrite the changes the other user made. Copying the changes to the clipboard will let you look at the values the other user entered, and then paste your changes back in if you decide to make changes.
Please help me find the cause of this behavior. Is it something I need to change in the MSAccess front end or something that needs to be set in the SQL Server back end by the network admin?
I am moving this question to the SQL Server Database Engine forum.
