column formula

Hi everybody,

I have an company table and it has 2 columns, Company Code and User Code, I

am incrementing "User Code" with "column identity" property of MS SQL Server

2K. I have different companies and those companies have different users. When

I increment User Code one by one, of course it doesnt consider whether it is

the same company or not.

Question 1: How can I satisfy this condition below?

EX:

company user
1---1
1---2
2---3
2---4
3---5
4---6

What I want is

company user
1---1
1---2
1---3
2---1
2---2
3---1
3---2
3---3

etc.


Question 2: I want to know that whether it is possible to do that by writing

column formula or not?You may want to add a third column for that information, so that you can have a column with PK for joining other tables to. Are you asking whether a script can be written to modify the user codes after they're entered, or as they're being entered?|||it's ok now, thanx for help
