Question

There have been some questions on this but I couldn’t find a relevant result for me. I have a query that gives me 2 columns of results:

 Day            Tot_dLS   
 01-Sep-12      10000
 02-Sep-12      9920

I want to transpose the Date so it reads:

01-Sep-12    02-Sep-12 
10000         9920

Is this possible?

Since you can return a fixed number of columns and you can use generic column names, you can do a standard pivot query

SELECT max( case when rn = 1 then tot_dls else null end ) col_1,
       max( case when rn = 2 then tot_dls else null end ) col_2,
       max( case when rn = 3 then tot_dls else null end ) col_3,
       <<25 more>>
       max( case when rn = 29 then tot_dls else null end ) col_29,
       max( case when rn = 30 then tot_dls else null end ) col_30
  FROM (SELECT day,
               tot_dls,
               rank() over (order by day) rn
          FROM your_table
         WHERE day between date '2012-09-01' 
                       and date '2012-09-02' -- Use whatever criteria you want here
       )
