Suppose you require to get the IDENTITY of the record just after inserting it in Database,using ADO.NET, using ExecuteNonQuery() command. You want ur sql_storedprocedure not to return the IDENTITY. IN that case you need to write the code as below:
//C#
string employeeName="developer";
string query = "Insert Into Employees(EmployeeName) Values (?)";
string query2 = "Select @@Identity";
int ID;
string connect = "Data Source=(local);Initial Catalog=TestDB;User ID=sa;Password=sa123";
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
cmd.Parameters.AddWithValue("", employeeName);
conn.Open();
cmd.ExecuteNonQuery();
cmd.CommandText = query2;
ID = (int)cmd.ExecuteScalar();
}
}
