| Our ASP / SQL applicaiton supports multiple administrators who can add users one at a time. The ASP page calls a SQL procedure to insert a user, something like...CREATE PROCEDURE UserInsert@Username varchar (100)ASINSERT Users (Username) VALUES (@Username)RETURN (@@IDENTITY)I see procedures coded like this frequently in textbooks, and @@IDENTITY defined as the most current row. I'm left wondering if @@IDENTITY could get involved in a race condition when two Administrators add users at the same time. Does this procedure's executable statements need to be wrapped in Transact SQL to ensure @@IDENTITY points to this Administrator's record???Sam |

| Nope. @@identity is the last identity allocated for that spid so what other admins are doing doesn't affect it..==========================================Cursors are useful if you don't know sql.DTS can be used in a similar way.Beer is not cold and it isn't fizzy. |
