为什么我收到Microsoft SQL：Power BI上的语法错误？

问题描述

我正在尝试使用CTE获取一些数据，但这给我一个错误，我必须使用分号。我想我把它固定了;在WITH前面，但现在我得到Microsoft sql: Incorrect Syntax near ';'. Incorrect Syntax near ')'.

有人可以告诉我哪里出了问题吗？过去非常简单，只需将查询从MS sql复制到Power BI。我的查询在MS sql中运行良好。

;WITH unit AS (
   SELECT
         tm.create_date,tm.timeslip_date,cases.case_sk,cases.case_number,cases.closed_ind,cases.atty2_sk,vc.atty2_name    AS [Business leader],em.smtp_reply_to AS [Business leader Email],cases.atty1_sk,vc.atty1_name    AS [Assign Attorney],tm.detail_notes
   FROM dbo.cases
   LEFT JOIN dbo.vcases vc ON cases.case_sk = vc.case_sk
   LEFT JOIN dbo.employee em ON cases.atty2_sk = em.employee_sk    
   LEFT JOIN dbo.timeslips tm ON cases.case_sk = tm.case_sk
   WHERE cases.closed_ind = 'O'
   AND NOT EXISTS(SELECT * FROM dbo.timeslips tsm WHERE tsm.case_sk = cases.case_sk AND tsm.timeslip_date > DATEADD(day,-90,GETDATE()) )
),agg AS (
   SELECT
         MIN(u.create_date)   AS [Created Date],MAX(u.timeslip_date) AS [Last Bill Date],u.case_sk,u.case_number,u.closed_ind,u.atty2_sk,u.[Business leader],u.[Business leader Email],u.atty1_sk,u.[Assign Attorney]
   FROM unit u
   GROUP BY 
         u.case_sk,u.[Assign Attorney]
)
SELECT agg.*,unit.detail_notes
FROM agg
INNER JOIN unit
   ON  agg.[Last Bill Date] = unit.[timeslip_date]
        AND agg.case_sk = unit.case_sk
        AND agg.case_number = unit.case_number
        AND agg.closed_ind = unit.closed_ind
        AND agg.atty2_sk = unit.atty2_sk
        AND agg.atty1_sk = unit.atty1_sk

谢谢

解决方法

当您使用自定义查询作为DirectQuery源时，必须提供一个PowerBI可以组成其他critera并在运行时加入的查询。

如果您使用这样的查询创建DirectQuery源

with q as (select * from sys.objects) select * from q

PowerBI将编写类似的查询

select * from (
    with q as (select * from sys.objects) select * from q
) SourceQuery where 1 = 2

您得到的错误与是否有语句终止符无关。在查询中间不允许使用;，但是with则是。 CTE很棒，但它们有一个缺点：它们不是“可组合的”。

您可以通过以下方式解决此问题：将查询安装为SQL Server中的视图，或将CTE子查询转换为嵌套子查询，但是该查询实际上太复杂了，无法在DirectQuery模型中使用。因此，您确实需要将结果加载到表中以使用DirectQuery，或者切换到“导入”并仅在刷新时运行查询。
