查询错误中使用“ with”语句进行数据提取

问题描述

我写了一个查询来提取一些数据，但出现错误，在使用多个WITH语句时我是sql的新手，出于隐私原因，我删除了一些列，如下所示，但是错误我如下所示。请给一些建议。谢谢

Database: Terradata 
Query: sql

错误：

SELECT Failed [ 3706] Syntax error: expected something between 'Study_Ongoing' and the 'AS' keyword 

查询：

 WITH Study_Ongoing AS
(
SELECT
    Clnc_Actv_Id
    
FROM
P_Clnc_Actv_Lif_Cyc
where Actv_Ongo_Fl=1
),Study_Ongoing_Group AS 
(
SELECT
    Clnc_Actv_Id as Actv_Id,Actv_Ongo_Fl
 
FROM
Study_Ongoing
GROUP BY
    Clnc_Actv_Id,Actv_Ongo_Fl,SO_Diff
)
Select 
    Actv_Id as "Protocol Id",FROM
Study_Ongoing_Group
 inner join X_Calendar Cal
 on Cal.CAL_DT >= Vldt_Strt_Dttm and Cal.CAL_DT < Vldt_End_Dttm
 where CAL_DT >= Date '2019-01-01'


WITH Study_Ongoing AS              --> ERROR Points here
(
SELECT
    Clnc_Actv_Id,Ptcol_Sts_Ctms

 inner join X_Calendar Cal
 on Cal.CAL_DT >= Vldt_Strt_Dttm and Cal.CAL_DT < Vldt_End_Dttm
 where CAL_DT >= Date '2019-01-01')

解决方法

Study_Ongoing AS （ 选择 Clnc_Actv_Id

FROM
P_Clnc_Actv_Lif_Cyc
where Actv_Ongo_Fl=1
),Study_Ongoing_Group AS 
(
SELECT
    Clnc_Actv_Id as Actv_Id,Actv_Ongo_Fl
 
FROM
Study_Ongoing
GROUP BY
    Clnc_Actv_Id,Actv_Ongo_Fl,SO_Diff
)
Select 
    Actv_Id as "Protocol Id",FROM
Study_Ongoing_Group
 inner join X_Calendar Cal
 on Cal.CAL_DT >= Vldt_Strt_Dttm and Cal.CAL_DT < Vldt_End_Dttm
 where CAL_DT >= Date '2019-01-01';   --> fixed with semicolon
