Multi-column report that repeats columns

Question

I don't know if this is possible:
COL A | COL B | COL C | COL A | COL B | COL C
1 | 2 | 3 | 4 | 5 | 6
7 | 8 | 9 | 10 | 11 | 12
So it would be a report being pulled from a single table, but the columns would be repeated across the page.
Has anyone ever done something like that?

Answer 1

Okay, firstly, the column titles can be defined any way you want except that they have to be unique names. This is called "aliasing" the columns.
select colA as A1, colB as B1, colC as C1, colA as A2, colB as B2, colC as C2
  from my_table
...What I am struggling with is the fact that you seem to have 12 distinct values (ostensibly coming from 12 distinct columns), so why would you want to show the same column name repeatedly?
If you are trying to combine information from several columns but place them in different rows, you can use a union and sort in this manner:
select A1, B1, C1, A2, B2, C2
from (
select ID, 1 as SORT_BY, colA as A1, colB as B1, colC as C1, colD as A2, colE as B2, colF as C2
  from my_table
union
select ID, 2 as SORT_BY, colG as A1, colH as B1, colJ as C1, colK as A2, colM as B2, colN as C2
  from my_table
order by ID, SORT_BYCan you give us an example of a record to go with the output?
