我有一个查询与几个聚合函数,然后几个分组列.我想从组中取出一个分组列,并对它具有的所有VARCHAR值执行某种聚合"连接".(理想情况下,在一个新的运输分离列表中).

这是我的查询,我注意到我想要这样做:

SELECT rownum, F.*
FROM (SELECT 
  c.logical_type "MerchantType",
  c.merchant_id "MerchantID",
  c.m_name "MerchantName",
  m.m_name "TransferredBy", /* <----- Make this aggregate */
  SUM(DECODE(b.ba_price,null,0,DECODE(b.BILL_SRVC_ID,'CREDITCHANGE',0,b.ba_price))) "TotalValue", 
  sum(DECODE(b.ba_price,null,0,DECODE(b.BILL_SRVC_ID,'CREDITCHANGE',b.ba_price,0))) "LimitChange", 
  SUM(DECODE(b.ba_status,'bdone',1,0)) "TxnCount",
  sum(to_number(decode(substr(b.ba_merchant_freetext,1,10),'Commission',substr(b.ba_merchant_freetext, 12,(instr(b.ba_merchant_freetext,';',1,1)-12))))) "Commission"
FROM bill_auth0 b,
  merchant0 m,
  merchant0 c
WHERE 
  b.srvc_prod_id = 'TRANSFER'
    AND b.ba_channel = 'WPSS'
    AND b.ba_status     IN ('bdone')
    AND b.merchant_id    = m.merchant_id
    AND b.customer_id    = c.merchant_id
    AND b.ba_timestamp BETWEEN to_date( '11/01/2009', 'MM/DD/YYYY' ) 
        AND to_date( '11/17/2009', 'MM/DD/YYYY' )+1
GROUP BY 
  c.logical_type,
  c.merchant_id,
  c.m_name,
  m.m_name /* <-- Remove from Grouped …
