我需要转换为“宽”格式，如此..
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 | .

2012-11-01 | 456 | 2 | Y | . | . | . | . | 1 | . | . | . | .
即使我不想以任何方式汇总数据，这是否可行？
答案 0 :(得分：5)
我不是很好的PIVOT表，但您可以使用以下备用CASE语句模式来获取您正在寻找的输出：
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

<强> Results ：
| DATE | PERSONID | SEQID | FUND1 | FUND2 | FUND3 | FUND4 | FUND5 | DBU1 | DBU2 | DBU3 | DBU4 | DBU5 |
