Question

I’m wondering if anyone could help me out here.

Is it possible when deleting a record to assign all instances of the deleted record to a new record?

For example:

For each project in a time planning database, i can assign a worker as team leader for each project. If there was a duplicate entry for a team leader i would need to delete one of the instances of these details. If you did this you would then be left with empty values for the records assigned to this ‘team leader’. This would be a problem.

I appreciate that you would want to nip this in the bud, so to speak, and not allow duplicate entries. However, if you would need to delete a record is it possible to assign a separate record in its place?

Hope that makes sense, if you could help me out it would be greatly appreciated.

Cheers

Cascade update is a possibility, but probably overkill for something that will only happen occasionally and should not happen at all. I suggest that you run a query to update the relevant records before you delete the team leader:

Update Projects Set TeamLeaderID=123 
Where TeamLeaderID=456
