c# MSSQL next ID
Posted on 2010-11-08
I have a web service which enters data in an SQL table. Website generates a request for the web service and gets an ID back immediately. Then the web service performs some actions and at last it enters the data with this id in the table. So I have to get the next possible id in the table, retur it to the website, perform some actions then insert the record with this id in the table.
Can you please tell me how I can get sure, that this ID will not be used by another thread? It seams insecure just to get the ID and then insert the record, because the actions which the service performs in between take quite some time. Can I look the table for this time? Will this influence the performance?
