Hello
I have created a table
CREATE TABLE MOD48_00_2007 ( ID text, N_GEN int PRIMARY KEY, FORMSTORE text, COD_NOTAIO text, PA_COGNOME text);
And i insert the rows via a form in ASP. When the form loads i have a functin that goes and gets the value of the field N_GEN adds 1 to it and shows it to the user.
The problem is when i have 2 users working at the same time.
For example the last value in my field N_GEN is 2
When both the users A and B loads the form (ASP page) it sees N_GEN = 3 :)
So they fill in the form and user A clicks on the button OK and the record has been inserted with N_GEN = 3. But when the user B clicks on the button the record is not inserted because it has the same key "3"
INSERT INTO MOD48_00_2007 (ID, N_GEN, FORMSTORE, COD_NOTAIO, PA_COGNOME) VALUES ('192168217200737122012', '3', '', '00128', 'DE MARTINIS')
Is there any way i can do this automatically? i mean maybe i have to use someother property instead of "Primary Key" ??
Thanks
