我是 Oracle 分析的新手。任何人都可以帮我解决以下问题。

SELECT year,
           month,
           week,
           C.cpg_pk                                                        CPG,
           C.dep_pk                                                        DEPT,
           T.cust_id                                                       CUST_ID,
           D1.r_id                                                         R_ID,
           Decode(d2.at_code, '3', func1.Get_att(d2.at_code, D2.val_code)) AS P1,
           Decode(d2.at_code, '2', func1.Get_att(d2.at_code, D2.val_code)) AS IC,
           Decode(d2.at_code, '1', func1.Get_att(d2.at_code, D2.val_code)) AS B1,
           Decode(func1.Get_att(d2.at_code, D2.val_code), 2, d2.at_code)   AS P2,
           Decode(func1.Get_att(d2.at_code, D2.val_code), 5, d2.at_code)   AS B2,

           Count(DISTINCT T.txn_pk)
           TOTAL_TXN,
           SUM(am_amount)                                                  TOTAL_AMT
    FROM   t_header T,
           cust_master A,
           tx_details1 D1,
           tx_details2 D2,
           cpg_master C
    WHERE  A.TYPE = 0
           AND T.cust_id = A.cust_id
           AND T.txn_pk = 5001
           AND T.txn_pk = D1.txn_pk
           AND T.txn_pk = D2.txn_pk
           AND D1.cpg_pk = C.cpg_pk
           AND D1.op = 1
    GROUP  BY year,
              month,
              week,
              C.cpg_pk,
              C.dep_pk,
              t.cust_id,
              D1.r_id,
              Decode(d2.at_code, '3', func1.Get_att(d2.at_code, D2.val_code)),
              Decode(d2.at_code, '2', func1.Get_att(d2.at_code, D2.val_code)),
              Decode(d2.at_code, '1', func1.Get_att(d2.at_code, D2.val_code)),
              Decode(func1.Get_att(d2.at_code, D2.val_code), 2, d2.at_code),
              Decode(func1.Get_att(d2.at_code, D2.val_code), 5, d2.at_code)

其生成的输出如下：

这里的值是重复的。我试图用 a 消除重复group by，但没有成功。你可以帮帮我吗？

所需的输出是这样的：

YEAR    MONTH   WEEK    CPG DEPT    CUST_ID R_ID    P1  IC  B1  P2  B2  TOTAL_AMT
---------------------------------------------------------------------------------
2012    08      32      127 -1      10019   3665    21  714 723  41   134 23100.09

主要的是year, month, week, cpg, dept, cust_id, r_id, p1, ic, b1, p2,b2应该是唯一的行。使用分析函数可以实现还是我需要编写 PL/SQL？我的问题合理吗？
