Re: Serial not nulla

Hello

I am working with a database that has a Index number defined as Serial NOT NULL

I used this because,
1. I want to make sure that when many users login at the same time the Index number won't be repeated.
2. I don't have to increment it by programming (I use ASP)

But now i have a situation that i need to index numbers. For Example i could have a structure like this

INDEX1 - N_SHEET - TOT_SHEET
1 - 1 - 1
2 - 1 - 3
2 - 2 - 3
2 - 3 - 3

N_SHEET and TOT_SHEET are filled by the user (via web) but i need to hold on to the INDEX. And while userA is filling the 3 row if userB loggs in i need to provide the INDEX1 with 3.

Any idea??

Thanks
 
Shavonne
