Question

我试图转换使用connect_by_root并通过之前连接的查询来消除先前的连接。原始查询是

SELECT   distinct CONNECT_BY_ROOT user.userid AS userid ,     
    CONNECT_BY_ROOT user.username USERNAME,     
    gr.BALANCE,
    client.agentid , 
    gr.closedt
    FROM user
    LEFT JOIN GAMEGROUP gr  ON (gr.userid= user.userid)  
    WHERE gr.closedt>= to_date('1/2/2014 0:0','DD/MM/YYYY HH24:MI') and  gr.closedt<= to_date('10/2/2014 23:59','DD/MM/YYYY HH24:MI')    
    START WITH user.agentid      IS NULL     CONNECT BY PRIOR  user.userid=user.agentid ;

我已将查询转换为

WITH r (USERID, USERNAME, BALANCE, AGENTID, PARTITIONDATE) AS
(SELECT distinct CONNECT_BY_ROOT user.userid AS userid,     
    CONNECT_BY_ROOT user.username USERNAME,     
    gr.BALANCE,    
    user.agentid , 
    gr.closedt
     FROM client   
    LEFT JOIN GAMEGROUP gr  ON (gr.userid= user.userid)  
    WHERE gr.closedt>= to_date('1/2/2014 0:0','DD/MM/YYYY HH24:MI') and  gr.closedt<= to_date('10/2/2014 23:59','DD/MM/YYYY HH24:MI')
UNION ALL
SELECT distinct CONNECT_BY_ROOT cl.userid AS userid,     
    CONNECT_BY_ROOT cl.username USERNAME,     
    g.BALANCE,
    cl.agentid ,
    g.closedt
    FROM r, user cl
    LEFT JOIN BACKOFFICE.GAMEGROUP g  ON (g.userid= cl.userid)  
    WHERE g.closedt>= to_date('1/2/2014 0:0','DD/MM/YYYY HH24:MI') and  g.closedt<= to_date('10/2/2014 23:59','DD/MM/YYYY HH24:MI') AND r.userid=cl.agentId)
SELECT * FROM r;

我收到此查询块中所需的错误ORA-01788 CONNECT BY子句。有人在我的新查询中看到问题吗？

通过先前的查询将连接转换为WITH
