将行转置为SQLite的查询

Question

下午好，我想知道是否可以进行查询以根据表中的行数生成列

example:

      ID       COD    DIAG
    111111111 | Z359 |  D   
    111111112 | Z359 |  D   
    111111112 | Z359 |  D   
    111111113 | Z359 |  R   
    111111113 | Z359 |  P   
    111111113 | Z359 |  R   
    111111114 | Z359 |  D   
    111111114 | Z359 |  D   
    111111114 | Z359 |  D   
    111111115 | Z359 |  D   


it would be ideal that columns be created according to the number of rows for each id, if not possible it would put a fixed number of columns.

    result query

        ID    | COD1 | DIAG1 | COD2 | DIAG2 | COD3 | DIAG3 
    111111111 | Z359 |   D   |      |       |      | 
    111111112 | Z359 |   D   | Z359 |   D   |      |
    111111113 | Z359 |   R   | Z359 |   P   | Z359 |  R
    111111114 | Z359 |   D   | Z359 |   D   | Z359 |  D
    111111115 | Z359 |   D   |      |       |      | 

对不起，我的英语

非常感谢！
