Hi,
I have an identity column where the identity seed is 1 and identity increment is 1. When i insert a record from a web application, it enters zero in the identity column. Any ideas?
Thanks.

Is IDENTITY_INSERT set to ON for that table while inserting?

Can you please provide the table script?

Yes, Identity insert is ON. I just created the table. It has not been truncated or reseeded.

Thanks.

Then change it to OFF. The identity column is there to be computed at the time you insert into the table. If you set IDENTITY_INSERT ON you allow inserts on the identity column: you push 0, you get 0.

I misread your earlier post. IsIdentity is on. But i don't know if Identity insert is on. How can i tell?

Thanks.

Ok, let's start from the table definition script: can you post it please?

You may want to read the article linked in my signature, you would find it useful.

Are you seeing 0's in your table currently, or are you referring to @@identity returning a 0 during this proc?

According to script and table definition, you should not be inserting any 0's nor should you be able to have any more than one 0 in your table.

Try adding a semi-colon after the insert statement, and try using ident_current rather than @@identity.

Off topic, but it's not a best practice to start stored procedures with "sp_" . That's generally reserved for SQL system SPs.

This stored procedure and the table definition has been working since the past 2 years. I just scripted the table definition from another database and then created the table on another database using the same script.

When I insert a record using a web application (which used the stored proc), it inserts zero into the identity column and @@Identity returns zero as well. When i run a query "select * from Customers", I see zero in the identity column.

Thanks.

What is the difference between the table where it is working and this other database and app where you just scripted out the table from?

Please run dbcc checkident against the table.

How many 0's do you have in your table currently?

Just 1 record with zero. If i insert data manully using query analyzer, then the second record is inserted with the identity of 2.

Here is another user who is complaining the same thing:

Do you have a trigger on the table?

There are no triggers on the table

the following is having the same issue:

Is there any way you could setup the table to perform some fresh tests?

If possible, drop and recreate the table - else truncate it (if this is a test environment only please).

As soon as the table is prepped, do the following:

dbcc checkident('customers',NORESEED)

Run your app (to perform a test insert)

dbcc checkident('customers',NORESEED)

Give the values for each of the checkident commands that you run.
