Question

using (SqlConnection connection = new SqlConnection(ConnectionString))
    {
        string query = "INSERT INTO SocialGroup (created_by_fbuid) VALUES (@FBUID); SELECT CAST(scope_identity() AS int)";
        SqlCommand command = new SqlCommand(query, connection);
        command.Parameters.AddWithValue("@FBUID", FBUID);

        connection.Open();
        command.ExecuteNonQuery();

        int lastID = (int)command.ExecuteScalar();

    }

Without the

SELECT CAST(scope_identity() AS int)

One row is inserted. But since I need the ID from the created row im using scope_identity. However, when I use this, 2 rows are created instead of one.

Did I miss something?

Thanks

The problem in the code you’ve posted is that you run 2 times the same query… one with ExecuteNonQuery(); and the last with (int)command.ExecuteScalar();

If you try to use only the executeScalar i think you have the result’s you want….

Try and hope this helps…

If you want you can use Parameter to retrieve the Identity, like they do in this Article
