Транспонировать строки в columsn в SQL

Question

Я хотел бы переместить строки в столбцы в sql.

Моя таблица выглядит следующим образом:

+-------+--------+--------------+---------+--------------+---------+----------------+---------+---------+---------+---------+---------+
|  ID   |  Desk  |   Reason1    | Amount1 |   Reason2    | Amount2 |    Reason3     | Amount3 | Reason4 | Amount4 | Reason5 | Amount5 |

| 34851 | Desk2  | TOC Reb      |       5 | SG & HK ETF  |       5 |                |       0 |         |       0 |         |       0 |
| 34853 | Desk3  | China        |      -5 | HK           |       0 | CNH            |       0 | HK2     |      35 |         |       0 |

| 34860 | Desk10 | CBBC TENCENT |       4 | CBBC HSI     |       1 |                |       0 |         |       0 |         |       0 |
+-------+--------+--------------+---------+--------------+---------+----------------+---------+---------+---------+---------+---------+

Как мне переставить таблицу в SQL, где причинами являются строкиа стол - колонны?

Требуется вывод:

+

----------------+---------+--------+-------------+--------+-------+--------+
|                |  Desk1  | Amount |    Desk2    | Amount | Desk3 | Amount |

Нормализованный дизайн может выглядеть примерно так:

reasons
+-----------+---------+----------------+--------+
| reason_id | desk_id | reason         | amount |

Если бы это был я, я бы начал отсюда.
