SQL Pivot на три столбца

/ 09 ноября 2011

У меня есть таблица с записями следующим образом 

  ID - Type - Code - Order
  1  - A - 3  - 1
  1  - A - 5  - 2

  1  - B - 88  -1
  1  - B - 99  -2
  1  - B - 123 -3

  2  - A - 7  - 1
  2  - A - 6  - 2
  2  - A - 1  - 3
  2  - A - 8  - 4

и т. Д.

Я хочу повернуть ID и произвести 

ID - A1 - A2 -  A3  -  A4  -  A5  - B1 - B2 - B3  -  B4  -  B5
1  - 3  - 5  - NULL - NULL - NULL - 88 - 99 - 123 - NULL - NULL

etc ..

Я могу сделать это, если ограничу его одним типом кода, но не могу понять, как включить второй.

Я попытался поставить префикс в поле «Заказ»с A и B, но это испортило порядок.

Я пытаюсь сделать это, но после DX100 перейдите к PROC1 -> PROC100Это точно такой же код, за исключением CodeType = Proce вместо Diagn

Вы не можете напрямую использовать два столбца в качестве источника для имен столбцов сводной таблицы.Но вы можете объединить их в исходной таблице следующим образом (если я правильно понимаю ваши намерения): 

SELECT
  ID,
  DX1 , DX2 , DX3 , DX4 , DX5 , DX6 , DX7 , DX8 , DX9 , DX10,

Взгляните на OUTER APPLY, здесь является хорошим примером.
