在 SQL Server 中，如何在列中显示表行值？ [复制]

Question

我正在使用 SQL Server 2012，我的表如下所示：

Customer    Status         StatusType
----------------------------------------
  3         Ok             personalInfo
  3         Pending        FinancialInfo
  3         NeedUpdate     CompanyInfo

要在这里得到结果，我需要一个 SQL 查询：

Customer    PersonalInfo    FinancialInfo   CompanyInfo
---------------------------------------------------------
    3       Ok              Pending         NeedUpdate

Answer 1

    CREATE TABLE #Table1
    ([Customer] int, [Status] varchar(10), [StatusType] varchar(13))
;

INSERT INTO #Table1
    ([Customer], [Status], [StatusType])
VALUES
    (3, 'Ok', 'personalInfo'),
    (3, 'Pending', 'FinancialInfo'),
    (3, 'NeedUpdate', 'CompanyInfo')      
SELECT * 
    FROM #Table1
    PIVOT ( max([status])
      for [StatusType] in ([PersonalInfo], [FinancialInfo], [CompanyInfo])) AS pvt

输出

Customer    PersonalInfo    FinancialInfo   CompanyInfo
3             Ok             Pending         NeedUpdate

或

DECLARE @cols AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX);

SET @cols = STUFF((SELECT distinct ',' + QUOTENAME(c.[StatusType]) 
            FROM #Table1 c
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

set @query = 'SELECT customer, ' + @cols + ' from 

                #Table1
    PIVOT ( max([status])
      for [StatusType] in ([PersonalInfo], [FinancialInfo], [CompanyInfo])) AS pvt'


exec(@query)
