Question

我有如下的SQL架构：

SELECT * FROM Table where rowid in(1,2,3)
SELECT * FROM Table where rowid in(2,1,3)
SELECT * FROM Table where rowid in(3,2,1)

这里我想得到多行相等的记录。条件是ANo，Code，Type，CPS，Tax需要直接比较。并且，如果Ex_Date和Rd_Date彼此相等或相差10天，那么它将被视为重复。注意：我想忽略Date1列。

所以，上面的架构应该是这样的：

ANo   | Code  |Type  | Date1  | EX_Date|Rd_Date |CPS | Tax 
______|_______| _____|______  |_ ______|_______ |____|__________
B1    |   AM  |  T   |4/1/2014|3/2/2012|4/2/2010| 99 | 1
B1    |   AM  |  T   |5/2/2014|3/5/2012|4/2/2010| 99 | 1
p1    |   4   |  X   |5/8/2014|3/4/2012|5/9/2015| 22 | 2
p2    |   3   |  Y   |8/1/2015|5/6/2011|7/8/2010| 20 | 3

它会很棒，如果有人能帮我PLSQL.Sql服务器也行。

Answer 1

如果你需要显示副本，它将类似于

select t1.* from Test t1
join Test t2 on 1=1
and t2.ANo = t1.ANo
and t2.Code = t1.Code
and t2."Type" = t1."Type"
and t2.CPS = t1.CPS
and t2.Tax = t1.Tax
and abs(t1.EX_Date - t2.EX_Date)  <= 10
and abs(t1.Rd_Date - t2.Rd_Date)  <= 10
group by t1.ANo, t1.Code,t1."Type", t1.Date1, t1.EX_Date,t1.Rd_Date,t1.CPS, t1.Tax
having count(t1.*) > 1;

SQL Fiddle

Oracle 11g R2架构设置：

CREATE TABLE Test ( ANo, Code,"Type", Date1, EX_Date,Rd_Date,CPS, Tax ) AS
          SELECT 'B1', 'AM', 'T', TO_DATE( '2014-04-01', 'YYYY-MM-DD' ), TO_DATE( '2012-03-02', 'YYYY-MM-DD' ), TO_DATE( '2010-04-02', 'YYYY-MM-DD' ), 99, 1 FROM DUAL
UNION ALL SELECT 'B1', 'AM', 'T', TO_DATE( '2014-05-02', 'YYYY-MM-DD' ), TO_DATE( '2012-03-05', 'YYYY-MM-DD' ), TO_DATE( '2010-04-02', 'YYYY-MM-DD' ), 99, 1 FROM DUAL
UNION ALL SELECT 'p1', '4',  'X', TO_DATE( '2014-05-08', 'YYYY-MM-DD' ), TO_DATE( '2012-03-04', 'YYYY-MM-DD' ), TO_DATE( '2015-05-09', 'YYYY-MM-DD' ), 22, 2 FROM DUAL
UNION ALL SELECT 'p2', '3',  'Y', TO_DATE( '2015-08-01', 'YYYY-MM-DD' ), TO_DATE( '2011-05-06', 'YYYY-MM-DD' ), TO_DATE( '2010-07-08', 'YYYY-MM-DD' ), 20, 3 FROM DUAL;

查询1 ：

SELECT *
FROM   TEST t
WHERE  EXISTS (
         SELECT 'X'
         FROM   TEST x
         WHERE  x.ROWID  <> t.ROWID
         AND    x.ANo    = t.Ano
         AND    x.Code   = t.Code
         AND    x."Type" = t."Type"
         AND    x.cps    = t.cps
         AND    x.tax    = t.tax
         AND    x.EX_DATE BETWEEN t.EX_DATE - INTERVAL '10' DAY AND t.EX_DATE + INTERVAL '10' DAY
         AND    x.RD_DATE BETWEEN t.RD_DATE - INTERVAL '10' DAY AND t.RD_DATE + INTERVAL '10' DAY
       )

| ANO | CODE | Type |                   DATE1 |                 EX_DATE |                 RD_DATE | CPS | TAX |
