Does SQL Server Express support all programmability features?

Is a sequence a function or DDL trigger?

I am using this as a reference
http://www.sqlteam.com/article/custom-auto-generated-sequences-with-sql-server

Objective:

Create a Waste Hauler Unique Number. For instance, 00000-V/C 0000- AT- YR

What do you mean by this?

You posted this in the 2005 section so I assume you are using 2005? SQL 2012 introduced the sequence. It is an object but not a function or a ddl trigger.

I am guessing that you want to create some sort of incrementing complex value? This is almost always a bad idea because it it a nightmare to get right. Concurrency is a real issue with a roll your own type of solution. There is lots of pain and little to gain. It would be far easier to use an identity as one column and the rest of the "key" in a second column.

Let me explain what exactly we are trying to do.

Waste Hauler Unique Number Example: 00000-V/C 0000- AT- YR

Requirements:

Hauler # = 00000 (permanent)- there may be 1000 hauler companies
Asset = V / C (vehicle or container + permanent #)
Material/Classification = AT (landfill / temporary)- this may be different
(Material: A- Landfill B-Recycling C-Compost)(Classification: T- Temporary P- Permanent)
YR = Year (2013)

So the best way to implement this is to use the Identity Property? Is that correct?

I just need to know a logical way to implement this.

Not sure exactly what you are trying to do from this. Are you wanting a single column to have all this information?

If I were going to generate a table to hold this data it would look something like this.


create table #Haulers
(
HaulerID int identity primary key,
Asset char(1),
Classification char(2),
Material char(1),
DateCreated datetime not null default getdate()
)

Our department wants to automatically generate permit numbers for our customers when they apply for a license.They want something similar to a key generator. Yes SQL Server is my only resource at this moment.

I can help but you have to help me understand the scope of what you are trying to do. Is there a certain format you need this to be in? Is there any reason these permit numbers can't be numeric?

This is the format they want 00000-V/C 0000- AT- YR

They want to be able distinguish if it’s a vehicle or container. They want to be able distinguish if it’s a temporary or permanent. It can’t be a numeric permit number.
