Как выполнить несколько пивотов на динамических столбцах

Question

Я пытаюсь сделать несколько сводок для динамических столбцов, но выдает ошибку. Я делаю группу, потому что она возвращает несколько пустых столбцов

Столбец «p.Parameter_1» недопустим в списке выбора. Образец таблицы

CREATE TABLE [dbo].[TrainingDetails](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Tid] [int] NOT NULL,
    [TrainingName] [nvarchar](50) NULL,
    [TDate] [nvarchar](50) NULL,
    [TPlace] [nvarchar](50) NULL,
    [Trainer] [nvarchar](50) NULL,
    [Facilitator] [nvarchar](50) NULL,
    [TrainingSubject] [nvarchar](50) NULL
) 


CREATE TABLE [dbo].[TrainngParticpntDtls](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [Tid] [int] NOT NULL,
    [PName] [nvarchar](50) NULL,
    [PRank] [nvarchar](50) NULL
) 

Может кто-нибудь, пожалуйста, помогите

желаемый вывод,

вставить оператор для вышеуказанного вопроса это: -
