Pivot query question

Question

I've a query in Oracle 11:
select to_char(da,'DY-DD') days
from (
        select rownum -1 + to_date('2012-10-15','yyyy-mm-dd') da, l
        from   (select level l
                from   dual  connect by level <= to_date('2012-10-21','yyyy-mm-dd') - to_date('2012-10-15','yyyy-mm-dd')+1)
        order by 1) Result
"DAYS"
MON-15
TUE-16
WED-17
THU-18
FRI-19
SAT-20
SUN-21What I need is that the present in a row instead of a column:
MON-15  TUE-16  WED-17  THU-18  FRI-19  SAT-20  SUN-21This should be done with pivot queries? Any suggestion please!
Thanks in advance.

Answer 1

While testing I discoverd that for some days I've more than 1 record for the ending and beginning balance for a day:
Mon15 Tue16
BB EB BB EB
17 19 27 21
19 27 21 26create statement for the table:
create table balances(b_date date, begining_balance number(10,2) , ending_balance number(10,2));insert for date:
begin
  INSERT INTO balances values('15-OCT-2012',17,19);
  INSERT INTO balances values('16-OCT-2012',19,21);
  INSERT INTO balances values('17-OCT-2012',21,8);
  INSERT INTO balances values('18-OCT-2012',8,7);
  INSERT INTO balances values('19-OCT-2012',7,1);
  INSERT INTO balances values('20-OCT-2012',1,17);
  Insert Into Balances Values('21-OCT-2012',17,19);
  Insert Into Balances Values('15-OCT-2012',19,27);
  Insert Into Balances Values('16-OCT-2012',21,26);
  End;
commit;I I use the min(case.......) clause I only get one balance. I've I remove the min from the clause I get all but also a lot of empty rows:
WITH     all_dates     AS
     SELECT     LEVEL               AS n
     ,     TO_DATE ( '15-Oct-2012'
               , 'DD-Mon-YYYY'
               ) + LEVEL - 1     AS a_date
     FROM     dual
     CONNECT BY     LEVEL     <= 7
,     unpivoted_data     AS
     SELECT     a.n
     ,     TO_CHAR (a.a_date, 'DyDD')     AS dydd
     ,     TO_CHAR (b.begining_balance)     AS beginning_balance
     ,     TO_CHAR (b.ending_balance)     AS ending_balance
     FROM     all_dates  a
     JOIN     balances   b  ON  b.b_date  = a.a_date
SELECT       MIN (CASE WHEN n = 1 THEN dydd END)     AS bb_1
,       MIN (CASE WHEN n = 1 THEN dydd END)     AS eb_1
,       MIN (CASE WHEN n = 2 THEN dydd END)     AS bb_2
,       MIN (CASE WHEN n = 2 THEN dydd END)     AS eb_2
,       1                                            AS r_num
FROM       unpivoted_data
    UNION ALL
SELECT       'BB'
,       'EB'
,       'BB'
,       'EB'
,       2     AS r_num
FROM       dual
    UNION ALL
SELECT        (CASE WHEN n = 1 THEN beginning_balance END)
,        (CASE WHEN n = 1 THEN ending_balance    END)
,        (CASE WHEN n = 2 THEN beginning_balance END)
,        (CASE WHEN n = 2 THEN ending_balance    END)
,       3   AS r_num
From       Unpivoted_Dataresult:
Mon15     Mon15     Tue16     Tue16     1
BB     EB     BB     EB     2
17     19               3
          19     21     3
                    3
                    3
                    3
                    3
19     27               3
          21     26     3is there a way I could ommit the null values in the query? I only want the output as:
Mon15 Tue16
BB EB BB EB
17 19 27 21
19 27 21 26Thanks in advance!
