Question

我试图从SQL 2008查询生成以下输出 -

JobID | Repair & Reshape | Refit Stripped Parts | Polishing 
1000  | true             | true                 | false
1001  | true             | true                 | false
1002  | true             | true                 | false
1003  | true             | true                 | false
1004  | true             | true                 | false

我的表结构是 -

JobDetails

ID - PK Auto increment
JobID - Int (Joined to Jobs table)
PhaseID - String (joined to JobPhases table)

JobPhases

ID - PK String
Name - VarChar(150)

到目前为止，我有 -

SELECT JobID, [0], [1], [2], [3], [4], [5], [6], [7]
 FROM    
(   
    SELECT  JobID, PhaseID, [x] = 1 FROM    JobDetails  
) JobDetails
PIVOT
(   SUM(x)
    FOR PhaseID IN ([0], [1], [2], [3], [4], [5], [6], [7])
) pvt

但不确定我将如何用作业阶段名称替换0-7等？

干杯

检查一下你可能会知道如何实现它

Distinct Row values as Columns Sql Server

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

    select @cols = STUFF((SELECT ',' + QUOTENAME(jobtype) 
                        from yourtable
                        group by jobtype
                        ORDER BY jobtype
                FOR XML PATH(''), TYPE
                ).value('.', 'NVARCHAR(MAX)') 
            ,1,1,'')
    --SELECT @cols
    set @query = 'SELECT  JobID,' + @cols + ' from 
                 (
                    select JobID, jobtype, jobvalue from yourtable
                ) x
                pivot 
                (
                    MAX(jobvalue)
                    for jobtype in (' + @cols + ')
                ) p '

    execute(@query)

Answer 2

JOIN在锚点查询中包含表格JobPhases的表格，然后使用FOR Name IN中的阶段名称列表并列出阶段的名称：

SELECT *
 FROM    
(   
    SELECT  j.JobID, j.PhaseID, p.Name, x
    FROM    JobDetails  AS j
    INNER JOIN JobPhases AS p ON p.ID = j.haseId
) JobDetails
PIVOT
(   SUM(x)
    FOR Name IN ([phasename1], [phasename2], ...)
) pvt

SQL SELECT基于连接表
