SQL pivot query error: Unclosed quotation mark

Question

我有 3 个表（1.Emp，2.OnLeave，3.DaysWeeks）。我正在尝试编写一个将 empname 和 calenderdates 显示为列的数据透视查询）

当我尝试运行数据透视查询时出现以下错误。

1.Unclosed 字符串'2016-12-31])) as pvt'后的引号。

2.Incorrect syntax near '2016-12-31])) as pvt'

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

SELECT @cols = STUFF((SELECT  ',' + QUOTENAME([CalDate]) 
                    FROM DaysWeeks
            FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')

SELECT @query = 
'WITH cte AS (
SELECT EmpDays.Employee,EmpDays.CalDate, ISNULL(v.VacationType,1) AS LeaveStatus
FROM dbo.OnLeave v
RIGHT OUTER JOIN
 (SELECT e.EmpID AS Employee, dw.CalDate AS CalDate, dw.DayOfWeekName AS DoWName
  FROM daysweeks dw,
      dbo.Emp e
      WHERE dw.CalYear = 2016 AND dw.monthnumber=1) AS EmpDays
ON
   v.EmpID = EmpDays.Employee
   AND v.StartingDate <= empdays.CalDate 
   AND v.EndingDate >= empdays.CalDate
)
SELECT * FROM cte PIVOT 
(Max(cte.LeaveStatus) FOR cte.CalDate in([' + @cols + '])) as pvt'


EXEC SP_EXECUTESQL @query

Answer 1

因为 QUOTENAME 已经添加到这里

 STUFF((SELECT  ',' + QUOTENAME([CalDate])

这里不需要 [ 和 ]，

 FOR cte.CalDate in([' + @cols + '])) as pvt'

这是错误的。它将使整个数据透视列列表被视为单列

改为

 FOR cte.CalDate in(' + @cols + ')) as pvt'

更新： 通过传递 deptId 值（@deptId as smallint =1）来过滤记录。像这样更改您的查询

Declare @deptId SMALLINT = 1

......
RIGHT OUTER JOIN
 (SELECT e.EmpID AS Employee, dw.CalDate AS CalDate, dw.DayOfWeekName AS DoWName
  FROM daysweeks dw,
      dbo.Emp e
      WHERE dw.CalYear = 2016 
        AND dw.monthnumber=1 
        AND e.deptId = @deptId ) AS EmpDays
......

EXEC SP_EXECUTESQL @query,N'@deptId SAMLLINT',@deptId = @deptId
