oracle - Get records where multiple rows are equal value sql server -

i have sql schema below:

ano   | code  |type  | date1  | ex_date|rd_date |cps | tax  ______|_______| _____|______  |_ ______|_______ |____|__________ b1    |    |  t   |4/1/2014|3/2/2012|4/2/2010| 99 | 1 b1    |    |  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 

here want records multiple rows equal values.the condition ano,code,type,cps,tax needs directly compared. and, if ex_date , rd_date equal or 10days of each other considered duplicate.note: wanted ignore date1 column.

so, above schema should come like:

ano   | code  |type  | date1  | ex_date|rd_date |cps | tax  ______|_______| _____|______  |_ ______|_______ |____|__________ b1    |    |  t   |4/1/2014|3/2/2012|4/2/2010| 99 | 1 b1    |    |  t   |5/2/2014|3/5/2012|4/2/2010| 99 | 1 

its great, if 1 can please me plsql.sql server ok.

oracle 11g r2 schema setup:

create table test ( ano, code,"type", date1, ex_date,rd_date,cps, tax )           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 dual union 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 dual union 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 dual union 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 dual; 

query 1:

select *   test t  exists (          select 'x'            test x           x.rowid  <> t.rowid          ,    x.ano    = t.ano          ,    x.code   = t.code          ,    x."type" = t."type"          ,    x.cps    = t.cps          ,    x.tax    = t.tax          ,    x.ex_date between t.ex_date - interval '10' day , t.ex_date + interval '10' day          ,    x.rd_date between t.rd_date - interval '10' day , t.rd_date + interval '10' day        ) 

results:

| ano | code | type |                   date1 |                 ex_date |                 rd_date | cps | tax | |-----|------|------|-------------------------|-------------------------|-------------------------|-----|-----| |  b1 |   |    t |   may, 02 2014 00:00:00 | march, 05 2012 00:00:00 | april, 02 2010 00:00:00 |  99 |   1 | |  b1 |   |    t | april, 01 2014 00:00:00 | march, 02 2012 00:00:00 | april, 02 2010 00:00:00 |  99 |   1 |
