三列上的SQL Pivot

Question

I've got a table with records as follows

  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

etc..

What I want is to pivot on ID, and produce

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

etc..

I can make this work if I restrict it to just one code type, but I can't figure out how to include a second.

I tried prefixing my Order field with an A and B, but this screwed up the ordering.

EDIT:

SELECT  [ID], 
[1]  AS DX1 ,[2]  AS DX2 ,[3]  AS DX3 ,[4]  AS DX4 ,[5]  AS DX5 ,[6]  AS DX6 ,[7]  AS DX7 ,[8]  AS DX8 ,[9]  AS DX9 ,[10] AS DX10,

)AS DiagPivot

What I am trying to do is have that, but after DX100, proceed to PROC1 -> PROC100 It is exactly the same code, except CodeType = Proce instead of Diagn

Answer 1

看看OUTER APPLY， 这是一个很好的例子。

Answer 2

You cannot directly use two columns as the source for the pivoted table's column names. But you could concatenate them in your source table, like this (if I understand your intent correctly):

SELECT
  ID,
  DX1 , DX2 , DX3 , DX4 , DX5 , DX6 , DX7 , DX8 , DX9 , DX10,
  DX11, DX12, DX13, DX14, DX15, DX16, DX17, DX18, DX19, DX20,
  DX21, DX22, DX23, DX24, DX25, DX26, DX27, DX28, DX29, DX30,
  DX31, DX32, DX33, DX34, DX35, DX36, DX37, DX38, DX39, DX40,
