如何在沒有聚合的情況下製作一張長桌子？

Question

我有金融交易的這個表..

PersonID | SeqId | FundId | PortfolioDbu | Date 
    ---------------------------------------------------------- 
     456  | 1  | B |  0.1  | 2012-04-03 
     456  | 1  | F |  0.5  | 2012-04-03 
     456  | 1  | H |  0.3  | 2012-04-03 
     456  | 1  | Z |  0.1  | 2012-04-03 
     8  | 1  | B |  0.5  | 2012-03-23 
     8  | 1  | A |  0.5  | 2012-03-23 
     8  | 2  | C |  0.3  | 2011-03-24 
     8  | 2  | X |  0.3  | 2011-03-24 
     8  | 2  | F |  0.4  | 2011-03-24 
     6001 | 1  | J |  0.5  | 2008-01-01 
     6001 | 1  | R |  0.5  | 2008-01-01 
     76  | 1  | A |  0.25  | 2010-09-26 
     76  | 1  | B |  0.25  | 2010-09-26 
     76  | 1  | C |  0.25  | 2010-09-26 
     76  | 1  | D |  0.25  | 2010-09-26 
     321  | 1  | X |  0.2  | 2012-02-21 
     321  | 1  | Y |  0.2  | 2012-02-21 
     321  | 1  | U |  0.2  | 2012-02-21 
     321  | 1  | P |  0.2  | 2012-02-21 
     321  | 1  | W |  0.2  | 2012-02-21 
     456  | 2  | Y |  1  | 2012-11-01 

，我需要轉換爲「寬」的格式，像這樣..

 Date  | PersonId | SeqId | Fund1 | Fund2 | Fund3 | Fund4 | Fund5 | Dbu1 | Dbu2 | Dbu3 | Dbu4 | Dbu5 
    ---------------------------------------------------------------------------------------------------------- 
    2012-04-03 | 456 | 1 | B | F | H | Z | . | 0.1 | 0.5 | 0.3 | 0.1 | . 
    2012-03-23 | 8  | 1 | B | A | . | . | . | 0.5 | 0.5 | . | . | .  
    2012-03-24 | 8  | 2 | C | X | F | . | . | 0.3 | 0.3 | 0.4 | . | . 
    2008-01-01 | 6001 | 1 | J | R | . | . | . | 0.5 | 0.5 | . | . | . 
    2010-09-26 | 76 | 1 | A | B | C | D | . | 0.25 | 0.25 | 0.25 | 0.25 | . 
    2010-02-21 | 321 | 1 | X | Y | U | P | W | 0.2 | 0.2 | 0.2 | 0.2 | 0.2 
    2012-11-01 | 456 | 2 | Y | . | . | . | . | 1 | . | . | . | . 

這是可能的，即使我不想要以任何方式彙總數據？

我不是真正的好樞軸表，但你可以使用下面這個替代CASE聲明圖案，讓你要尋找的輸出：

WITH T AS (
    SELECT 
    personid, 
    seqid, 
    row_number() over (partition BY personid,seqid ORDER BY FundId) AS ROW, 
    FundId, 
    portfoliodbu, 
    date 
    FROM 
    transactions 
) 
SELECT 
    date, 
    personid, 
    seqid, 
    max(CASE WHEN ROW=1 THEN fundid END) AS fund1, 
    max(CASE WHEN ROW=2 THEN fundid END) AS fund2, 
    max(CASE WHEN ROW=3 THEN fundid END) AS fund3, 
    max(CASE WHEN ROW=4 THEN fundid END) AS fund4, 
    max(CASE WHEN ROW=5 THEN fundid END) AS fund5, 
    max(CASE WHEN ROW=1 THEN portfoliodbu END) AS dbu1, 
    max(CASE WHEN ROW=2 THEN portfoliodbu END) AS dbu2, 
    max(CASE WHEN ROW=3 THEN portfoliodbu END) AS dbu3, 
    max(CASE WHEN ROW=4 THEN portfoliodbu END) AS dbu4, 
    max(CASE WHEN ROW=5 THEN portfoliodbu END) AS dbu5 
FROM 
    T 
GROUP BY 
    date,personid,seqid

Results：

|        DATE | PERSONID | SEQID | FUND1 | FUND2 | FUND3 | FUND4 | FUND5 | DBU1 | DBU2 | DBU3 | DBU4 | DBU5 |
