编写CLR存储过程中使用SqlDataRecord

[Microsoft.SqlServer.Server.SqlProcedure]
    public static void GetFruitByKind(SqlByte kind_nbr)
    {
        SqlConnection connection = new SqlConnection("context connection=true");
        connection.Open();

        string commandText = "SELECT [Fruit_nbr],[FruitKind_nbr],[FruitName] FROM [dbo].[Fruit] WHERE [FruitKind_nbr] = @Kind_nbr ";

        SqlCommand command = new SqlCommand(commandText, connection);

        SqlParameter param = new SqlParameter("@Kind_nbr", SqlDbType.TinyInt);
        param.Value = kind_nbr;
        command.Parameters.Add(param);

        SqlDataReader reader = command.ExecuteReader();

        SqlDataRecord record = new SqlDataRecord(
        new SqlMetaData("Fruit_nbr", SqlDbType.TinyInt),
        new SqlMetaData("FruitKind_nbr", SqlDbType.TinyInt),
        new SqlMetaData("FruitName", SqlDbType.NVarChar, 100, 1033, SqlCompareOptions.None)
        );

        SqlContext.Pipe.SendResultsStart(record);

        while (reader.Read())
        {
            record.SetByte(0, Convert.ToByte(reader["Fruit_nbr"]));
            record.SetByte(1, Convert.ToByte(reader["FruitKind_nbr"]));
            record.SetString(2, reader["FruitName"].ToString());

            SqlContext.Pipe.SendResultsRow(record);
        }

        SqlContext.Pipe.SendResultsEnd();
    }
