Row to Column conversion

Question

Hi,
i am having following table
SELECT* FROM Col_to_row;
output is:
A      B      C
X      Y      Z
1      2      3
i want to write query for below output, need to convert row into column for n number of rows for example i have taken only 3 rows:
A X 1
B Y 2
C Z 3

Answer 1

Three things to notice in this solution:
1) I am ordering by the original column name. You may want to order by something else.
2) When pivoting, you must indicate the name, number and datatype of the columns, so if there is a fourth line of input you have to add a column to the query.
3) This works on Oracle 11GR1 and above. Next time, be sure to indicate your Oracle version from the start.create table COL_TO_ROW(C1, C2, C3) as select
'A', 'B', 'C' from DUAL union all select
'X', 'Y', 'Z' from DUAL union all select
'1', '2', '3' from dual;
select * from (select rownum rn, a.* from COL_TO_ROW a)
UNPIVOT(VAL for COL in(C1, C2, C3))
PIVOT(max(VAL) for RN in (1,2,3))
order by col;
COL 1 2 3
C1  A X 1
C2  B Y 2
C3  C Z 3
