Sql server 2005 如何在SQLServer2005中将多个表中的行转换为具有值的列

我有一个用户表

第二语言表，包含用户可以说的语言

第三个passport表，其中包含用户的passport详细信息（用户可以有多个passport）

[除了这些，我还有5张桌子]

我想将这些语言和passport行转换为列，并将其转换为一个结果集（同时包含用户详细信息），并且在结果集中，根据用户所能说的语言和持有的护照，每个用户记录的语言和passport列应显示是/否值。输出如下所示：

我们可以通过使用PIVOT来实现这一点。我尝试了使用单个表，但如何对多个表执行此操作

谢谢你能试试吗

select
  *
from
(
  select
    u.Username, u.department, c.countrypassport
  from User U
  inner join country C
    on C.userid=U.userid
) DataTable
PIVOT
(
  SUM(countrypassport)
  FOR countrypassport
  IN (
    [American],[Arabic],.....
  )
) PivotTable

也许是这样的：

DECLARE @query NVARCHAR(4000)=
N';WITH CTE
AS
(
    SELECT
        #tblContryPassport.userid,
        ''yes'' AS Answer,
        #tblContryPassport.contryPassport AS Name
    FROM
        #tblContryPassport
    UNION ALL
    SELECT
        #tblLanguage.userid,
        ''yes'' AS Answer,
        #tblLanguage.[language] AS Name
    FROM
        #tblLanguage
)
SELECT
    userName,
    department,
    '+@colsWithIsNull+'
FROM
(
    SELECT
        #tblUser.userid,
        #tblUser.userName,
        #tblUser.department,
        CTE.Answer,
        CTE.Name
    FROM
        #tblUser
        JOIN CTE
            ON #tblUser.userid=CTE.userid
) AS p
PIVOT
(
    MAX(Answer)
    FOR Name IN ('+@cols+')
) AS pvt'

EXECUTE(@query)

首先，测试数据：

CREATE TABLE #tblUser 
            (
                userid INT, 
                userName VARCHAR(100),
                department VARCHAR(100)
            )
CREATE TABLE #tblLanguage 
            (
                uniqueid INT,
                userid INT,
                [language] VARCHAR(100)
            )
CREATE TABLE #tblContryPassport
            (
                uniqueid INT,
                userid INT,
                contryPassport VARCHAR(100)
            )
INSERT INTO #tblUser
VALUES
    (1,'aa','TT'),
    (2,'bb','gg'),
    (3,'cc','rr'),
    (4,'dd','dd')
INSERT INTO #tblLanguage
VALUES
    (1,1,'American'),
    (1,1,'Arabic'),
    (1,2,'Azerbaujani'),
    (1,3,'Bulgarian'),
    (1,3,'Chaochow'),
    (1,4,'Behdini')
INSERT INTO #tblContryPassport
VALUES
    (1,1,'Hongkong'),
    (1,1,'Malaysia'),
    (1,2,'Spain'),
    (1,3,'China'),
    (1,4,'India'),
    (1,4,'UK')

然后单击轴的唯一列。如果有两个，则选择其中一个：

DECLARE @cols VARCHAR(MAX),
        @colsWithIsNull VARCHAR(MAX)
;WITH CTE
AS
(
    SELECT
        #tblContryPassport.contryPassport AS Name
    FROM
        #tblContryPassport
    UNION ALL
    SELECT
        #tblLanguage.[language] AS Name
    FROM
        #tblLanguage
), CTE2
AS
(
    SELECT
        ROW_Number() OVER(PARTITION BY name ORDER BY name) AS iRank,
        CTE.Name
    FROM
        CTE
)
SELECT  @cols = COALESCE(@cols + ','+QUOTENAME(Name),
                     QUOTENAME(Name)),
        @colsWithIsNull=COALESCE(@colsWithIsNull + ',ISNULL('+QUOTENAME(Name)+',''no'') AS '+QUOTENAME(Name),
                     'ISNULL('+QUOTENAME(Name)+',''no'') AS '+QUOTENAME(Name))
FROM
    CTE2
WHERE
    iRank=1

然后执行如下动态轴心：

DECLARE @query NVARCHAR(4000)=
N';WITH CTE
AS
(
    SELECT
        #tblContryPassport.userid,
        ''yes'' AS Answer,
        #tblContryPassport.contryPassport AS Name
    FROM
        #tblContryPassport
    UNION ALL
    SELECT
        #tblLanguage.userid,
        ''yes'' AS Answer,
        #tblLanguage.[language] AS Name
    FROM
        #tblLanguage
)
SELECT
    userName,
    department,
    '+@colsWithIsNull+'
FROM
(
    SELECT
        #tblUser.userid,
        #tblUser.userName,
        #tblUser.department,
        CTE.Answer,
        CTE.Name
    FROM
        #tblUser
        JOIN CTE
            ON #tblUser.userid=CTE.userid
) AS p
PIVOT
(
    MAX(Answer)
    FOR Name IN ('+@cols+')
) AS pvt'

EXECUTE(@query)

然后在我的情况下，我将删除临时表：

DROP TABLE #tblUser
DROP TABLE #tblContryPassport
DROP TABLE #tblLanguage
