Hi, There are three ways to get the identity value from the sql server. @@SCOPE_IDENTITY and @@IDENTITY return the last identity values that are generated in any table in the current session. However, SCOPE_IDENTITY returns values inserted only within the current scope; @@IDENTITY is not limited to a specific scope. Instead of writing separate logic to read the identity value after inserting it can returns the stored procedure with output parameter. CREATE PROC sp_getIdentity @id int output,@name varchar(20) as INSERT INTO t1 (name) VALUES (@name); select @id = SCOPE_IDENTITY() go Then call the stored procedure in a sql command: SqlCommand cmd = new SqlCommand("sp_getIdentity", connection); connection.Open(); SqlParameter sp= new SqlParameter("@id",SqlDbType.Int); sp.Direction = ParameterDirection.Output; cmd.CommandType = CommandType.StoredProcedure; cmd.Parameters.Add(sp); int id=sp.Value.ToString(); For more info: http://www.dotnetfunda.com/articles/article1547-how-to-retrieve-identity-auto-incremented-value-using-output-paramter-thr.aspx http://www.mikesdotnetting.com/Article/54/Getting-the-identity-of-the-most-recently-added-record http://ramanisandeep.net/tag/how-to-retrieve-the-identity-value/

using LINQ MyBDDDataContext db = new MyBDDDataContext(); record newRecord = new record(); newRecord.record_title = newRecordBDD.Title; newRecord.record_text = newRecordBDD.Text; newRecord.record_date = DateTime.Now; db.records.InsertOnSubmit(newRecord); try { db.SubmitChanges(); int id = newRecord.ID; // you can access your newRecord to get the ID } catch (Exception) { throw; } If it's helpful to you then please check as Accepted Answers
