Hi All,
I need to auto increment an id (long int) based on the incoming
concurrent requests. I'll be incrementing the max of existing value by
1 and persist the value in the same xml. My assumption is since I'm doing
this in a single transaction and also I have an update statement in this
transaction, a lock will be obtained on that xml so that the next request
will have to wait for the lock to be released and when the second request
increments the id value from the max of existing values it will take the
latest value. Am I right? If not, is there some other way to do it? Please
note that I don't need a timestamp as my ID, I need to have an integer. I
just need the relational database style auto increment feature which should
give me unique id even if there are concurrent requests.Also note all the
requests are from the same user so I cannot use a lock acquire for that
user.
Thanks
Raghu
