Is there any way to treat Lock record in table with clientdataset?

Hello guys

I have a table and two users request the record at the same time.

When the first user gets the record, the second should must get a message about the record is locked.

How should I do that with clientdataset?

This is more complex than you think. Please look at Optimistic concurrency control idea... Probably, you need additional field in a table... With Lock function set some value if empty (like username) and on Unlock - clear field... Assess row if username is equal...
