Updating identity column sql server

All I'm doing is creating a new entity and then calling the entity Save() method, and I get the message: "Cannot insert explicit value for identity column in table when IDENTITY_INSERT is set to OFF."Maybe I could insert a cfquery and explicitly turn it on before calling the entity Save method, but wouldn't that defeat the purpose of the ORM framework? But it doesn't work when a table contains Foreign Keys.

I just keep getting "Cannot insert explicit value for identity column in table when IDENTITY_INSERT is set to OFF."I am using SQL Server 2008 and executing the the script from SQL Server Management Studio USE Adventure Works2008R2; GO-- Create tool table. Tool( ID INT IDENTITY NOT NULL PRIMARY KEY, Name VARCHAR(40) NOT NULL)GO-- Inserting values into products table. Is there some special command required for Foreign Key Inserts?

Let’s take a look at what a Sequence is in relation to an Identity Column in SQL Server. See this little folder, ever notice it under Programmability in Management Studio.

It’s amazing how much you can skip over and never notice in SSMS.

@Stephen - Make sure that the table with PK that the FK refers to is populated first.

Also, you can only have one table at time with SET IDENTITY_INSERT set to 'ON', so you must set it to 'OFF' if you before setting it to 'ON' for the next table in a script.

Summary So, this was just a quick look what a Sequence is compared to an Identity column. If you’re looking for a unique value your best bet it to go with an Identity Column and the Primary Key option.

If you want just an auto-generated value to be able to use in an application outside of a table a Sequence is a sure bet.

But in my case I generated a data warehouse house with bi GENi US, a data warehouse automation tool.

To avoid gaps in the values of the Identity column in cases where the server restarts unexpectedly or fails over to a secondary server, disable the IDENTITY_CACHE option.

This option is similar to the existing SQL Server Trace Flag 272, except that it can be set at the database level rather than only at the server level.

I have been moving over the data from one database to another and am currently using XML files as an intermediate step.

The process has been going very smoothly, and I just learned something new. I thought they were referring to the DB's insert functionality, and so, I thought I had to turn it OFF in order to insert my own values.
