SQL - ";"附近的语法不正确

Question

我有一个写递归SQL查询,返回一些int值.SQL查询如下所示:

;WITH GroupHIERARCHY(ID)  
    AS  (  SELECT ID   
    FROM tFirstTable te  
    WHERE te.LevelID <> 0   
    AND GroupID =-1
    UNION ALL  
    SELECT t.ElementID  
    FROM tFirstTable AS t, tSecondTable,GroupHIERARCHY  
    WHERE t.TypeID=tSecondTable.TypeID  
    AND GroupHIERARCHY.ID= t.GroupID)

    SELECT ID FROM GroupHIERARCHY

这将返回一些整数值.(工作正常)我想要做的是我想写一个如下的查询:

Select * from tExampleTable 
WHERE FirstParameter IN (IntegerValuesHere) OR SecondParameter IN (IntegerValuesHere)

其中,IntegerValuesHere是我从递归查询中获得的值.

查询现在看起来像:

Select * FROM tExampleTable 
    WHERE FirstParameter IN (
        ;WITH GroupHIERARCHY(ID)  
        AS  (  SELECT ID   
        FROM tFirstTable te  
        WHERE te.LevelID <> 0   
        AND GroupID =-1
        UNION ALL  
        SELECT t.ElementID  
        FROM tFirstTable AS t, tSecondTable,GroupHIERARCHY  
        WHERE t.TypeID=tSecondTable.TypeID  
        AND GroupHIERARCHY.ID= t.GroupID)

        SELECT ID FROM GroupHIERARCHY
        ) 

    OR SecondParameter IN (
        ;WITH GroupHIERARCHY(ID)  
        AS  (  SELECT ID   
        FROM tFirstTable te  
        WHERE te.LevelID <> 0   
        AND GroupID =-1
        UNION ALL  
        SELECT t.ElementID  
        FROM tFirstTable AS t, tSecondTable,GroupHIERARCHY  
        WHERE t.TypeID=tSecondTable.TypeID  
        AND GroupHIERARCHY.ID= t.GroupID)

        SELECT ID FROM GroupHIERARCHY
    )

但是,我得到一个错误,说:

";"附近的语法不正确 和')'附近的语法不正确

首先,对于;前面WITH.第二,对于)以前OR.我错过了什么？

你不能CTE像你想要的那样筑巢.你可以像这样使用它:

;WITH GroupHIERARCHY(ID)  
    AS  (  SELECT ID   
    FROM tFirstTable te  
    WHERE te.LevelID <> 0   
    AND GroupID =-1
    UNION ALL  
    SELECT t.ElementID  
    FROM tFirstTable AS t, tSecondTable,GroupHIERARCHY  
    WHERE t.TypeID=tSecondTable.TypeID  
    AND GroupHIERARCHY.ID= t.GroupID)    
Select * 
from tExampleTable 
WHERE FirstParameter IN (SELECT ID FROM GroupHIERARCHY) OR 
      SecondParameter IN (SELECT ID FROM GroupHIERARCHY)
