Hi.
Is there a convenient way to lock SQL records so that two users cannot
attempt to update the same row, thereby preventing users from overwriting
other user's data?
For example, we have a asp.net 2.0 application which allows a user to pull
up customer information, modify their information and save it back to the
database. if there is a different user attempting to pull up that same
customer record while the other user is viewing it in their browser we would
like to display a message "the customer record you are trying to access is
currently locked by another user."
We may also want to give each user a certain amount of time to have a record
locked before releasing it for access by other users.
Any advice would be appreciated.
Thanks!

As a followup, I now convert the timestamp/rowversion column to a bigint
when I pull it up to the webpage.
I've seen some other tricks, but that one works for me.
Select EmpID, convert(bigint, MyTimeStampColu mn) as
MyTimeStampColu mnAsBigInt, LastName, FirstName from dbo.Employee
something like that.

ACCESS 97, Pessimistic Record Locking!???
Does Access 97 allow record level Pessimistic locking?
In other words, when user A is editing a record (has it locked) and
User B tries to edit it (attempts to lock it), user B will get
an error
saying this record cannot be locked now.
It seems like Access 97 is doing optimistic record level locking. In
above scenario user B, is allowed to edit the record but when tries to

I have been ok with optimistic locking most of the time but I have a
situation now where there is more of a chance that users could try to
edit a record at the same time. I'd like to use pessimitic locking, but
it's not working quite as I expected. I've read all over, and by now
have posted elsewhere on this subject, and (strangely it would seem)
have made no progress. This seems to be a bit of a blank spot on the
