为什么我收到 Microsoft SQL: Power BI 语法错误？

Question

我正在尝试使用 CTE 获取一些数据，但出现错误提示我必须使用分号。我想我通过放置 ; 解决了这个问题在 WITH 前面，但现在我得到 Microsoft SQL: Incorrect syntax near ';'. Incorrect syntax near ')'.

谁能告诉我哪里出了问题？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.case_number
       , u.closed_ind
       , u.atty2_sk
       , u.[Business Leader]
       , u.[Business Leader Email]
       , u.atty1_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

当您使用自定义查询作为 DirectQuery 源时，您必须提供一个查询，PowerBI 可以在运行时组成额外的条件并加入。

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 将编写如下查询

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

你得到的错误与你是否有语句终止符无关。 ; 不允许出现在查询中间，但 with 是不允许的。 CTE 很棒，但它们有一个缺陷：它们不是“可组合的”。

您可以通过在 SQL 服务器中将查询作为视图安装，或将 CTE 子查询转换为嵌套子查询来解决此问题，但该查询确实太复杂了，无法在 DirectQuery 模型中使用。因此，您确实需要将结果加载到 table 中才能使用 DirectQuery，或者切换到导入并运行仅在刷新时查询。
