问题 I'm trying to grab thousands of invoices (and other stuff) from a text file and insert them into SQL Server 2008. I wrote a little console app to do this and it uses LINQ to SQL. After I insert all the existing invoices I want the Invoice_ID to be an identity column and auto-increment, so I have it designed as such: CREATE TABLE [dbo].[Invoice] ( [Invoice_ID] int IDENTITY(1,1) NOT NULL PRIMARY KEY, /* Other fields elided */ ) Before I start inserting invoices I call a stored procedure that

I'm working on upsizing a suite of MS Access backend databases to SQL Server. I've scripted the SQL to create the table schemas in SQL Server. Now I am trying to populate the tables. Most of the tables have autonumber primary keys. Here's my general approach: For each TblName in LinkedTableNames 'Create linked table "temp_From" that links to the existing mdb' 'Create linked table "temp_To" that links to the new SQL server table ExecutePassThru "SET IDENTITY_INSERT " & TblName & " ON" db.Execute "INSERT INTO temp_To SELECT * FROM temp_From", dbFailOnError ExecutePassThru "SET IDENTITY_INSERT "

How to automatically reseed after using identity_insert?

I recently migrated from a PostgreSQL database to a SQL Server database. To switch the data over I had to enable IDENTITY_INSERT. Well come to find out that I get all sorts of strange errors due to duplicate identity values(which are set as primary keys) upon doing an insert in any of the tables. I have quite a few tables. What would be the easiest way of automatically reseeding the identity of every table so that it is after max(RID) ? Tommy Use the information in this link in combination with a SQL function that gets the max(RID) from each table that you need to reset. For instance, if you

Using IDENTITY_INSERT with EF4

I am trying to create a record in the db that has a predefined primary key value. I know how to do this with sql, but I was wondering if EF can do this for me? Otherwise, I will have to create a stored proc for the inserts. Devart In case you have the StoreGeneratedPattern attribute set to "None" for your entity, the Entity Key value you specify for it will be passed to database. In case this attribute is set either to "Identity" or to "Computed" there is no way to control what value will be set to this column in DB. So, if you have an auto-incremented column in your database and the ADO.NET
