How to achive this result .
I dont have any idea to do this query.
Please help guys.
Thanks in advance.

Well,
As long as your code doesn't have to run in production, simplest way is:
WM_CONCAT (but it's not documented)
or use XMLAGG, it's simpler than a connect by:
MHO%xe> with t as (
2 select 1 col, 'xy' str from dual union all
3 select 2, 'xyy' from dual union all
4 select 3, 'mm'from dual union all
5 select 4, 'pp' from dual union all
6 select 8, 'pp' from dual union all
7 select 12, 'pp' from dual union all
8 select 40, 'pp' from dual
9 )-- actual query, based on id's generated above:
10 select rtrim(xmlagg(xmlelement(e,col||',')).extract('//text()'),',') col
11 from t;
COL
1,2,3,4,8,12,40
1 rij is geselecteerd.

How to convert single column into single row

I need to convert single column into single row having n no.of.values in a column. without using case or decode. I need a query to display as below.
emp_id
100
101
102
102
103
200
I need output like 100,101,102,103,104.........200.

I assume you want to convert 200 rows with one column into one row with 200 columns. If so, this is called pivot. If you know number of rows (max possible number of rows) and you are on 11G you can use PIVOT operator (on lower versions GROUP BY + CASE). Otherwise, if row number isn't known, you can use dynamic SQL or assemble select on clent side. Below is example emp_id = 1,2,..5 (to give you idea) and you are on 11G:
with emp as (
             select level emp_id
               from dual
               connect by level <= 5
select *
from emp
pivot(
        max(emp_id) for emp_id in (1 emp_id1,2 emp_id2,3 emp_id3,4 emp_id4,5 emp_id5)
   EMP_ID1    EMP_ID2    EMP_ID3    EMP_ID4    EMP_ID5
         1          2          3          4          5

Converting columns into rows

Dear all....I need to convert all columns into rows in a table. For example table has following columns:
Emp_Cod........Val1......Val2......Val3
1 a b c
Now I wish that each column should display as a value like:
Emp_Cod........Val1
1 a
1 b
1 c
Now the one way to solve this job is to write a union statement for each column but for this I'll have to write equal number of select statements as there are columns.
What I need that is there anyway to write minimum code for this job, is there any alternate way???

SQL> with t as(select 1 emp_code, 'a' val1, 'b' val2, 'c' val3 from dual)
2 select*from t unpivot(v for c in(val1,val2,val3));
EMP_CODE C     V
        1 VAL1 a
        1 VAL2 b
        1 VAL3 c
SQL> col COLUMN_VALUE for a20
SQL> with t as(select 1 emp_code, 'a' val1, 'b' val2, 'c' val3 from dual)
2 select*from t,table(sys.odcivarchar2list(val1,val2,val3));
EMP_CODE V V V COLUMN_VALUE
        1 a b c a
        1 a b c b
        1 a b c c

How to display the rows in to columns and columns into rows?

DES:- I know by using pivot and unpivot you can convert rows into columns and columns into rows but i don't know how to write the syntax?

Hi,
Besides the places Martin mentioned above, there are many examples in the forum FAQ:

Converting multiple columns into one.

All,
I have a requirement to convert multiple columns into one. Following is the pseudo code of current implementation. It unions the various columns ( col1, col2........) into a new column new_col. But perforamnce is extrmely slow owing to multiple unions. It may be noted that tables and where conditions of all these queries are same.
Can you help me create a more efficient query?
select col1 , col2, col3, col4 from my_tables where some_cols = my_condition;Below is the query used to convert these columns into one.
select col1 new_col from my_tables where some_cols = my_condition
union all
select col2 from my_tables where some_cols = my_condition
union all
select col3 from my_tables where some_cols = my_condition
union all
select col4 from my_tables where some_cols = my_condition

Without looking at those things you could be barking up the wrong tree by assuming the issue relates to the unioning of queries or other such things.Well, might be.........

Note that the above SQL performs the following steps:
    * determines how many elements are in each string (WITH clause);
    * for each string, generates a collection of n elements (TABLE expression), where n is the derived number of elements in the string. Note in particular the use of "less than" in the "CONNECT BY ROWNUM < ilv.no_of_elements" on line 26. In all versions other than 10.1.x, this will need to be "CONNECT BY ROWNUM <= ilv.no_of_elements" (i.e. "less than or equal to"). There is an unusual bug with this row-generation technique in 10.1 that generates an additional row from the CONNECT BY;
    * uses the generated rows in a Cartesian Product with the original data to generate n rows per string, based on the above definition of n;
    * calculates the start and end position of each element in each string (INSTR); and
    * cuts each element from each string (SUBSTR).

col2 d2
col3 d3
for this i have written the query as
select column_name,column_data from (select * from XXX where col1=123)
MODEL RETURN UPDATED ROWS
dimension by(col1)
measures (col1,0 column_name,0 column_data )
ignore nav
rules ITERATE(167)
column_name[iteration_number]=cast( iteration_number as varchar2(3)),
column_data[iteration_number]=cast( iteration_number as int)
here i am just assigning iteration_number but i want to assign name of the column and its value;
Note:--table contains nearly 200 columns

Something like (using one of my own tables):
select column_name colname,
       decode(column_name,'RUN_NO',to_char(run_no),
                          'SEARCH_ID',to_char(search_id),
                          'PROCESSING_START_DATE',to_char(processing_start_date,'DDMMYYYYHH24MISS'),
                          'PROCESSING_END_DATE',to_char(processing_end_date,'DDMMYYYYHH24MISS'),
                          'NO_OF_MATCHES',to_char(no_of_matches),
                          'ERROR_DETAILS',error_details,
                          'ADVREP_TIMESTAMP',to_char(advrep_timestamp,'DDMMYYYYHH24MISS')
              ) colvalue
from partial_search_history, (select rownum r, column_name
                              from user_tab_columns
                              where table_name = 'PARTIAL_SEARCH_HISTORY')
where run_no = 356You can build the decode by doing
SELECT ''''||COLUMN_NAME||''',TO_CHAR('||COLUMN_NAME||'),'
FROM user_tab_columns
where table_name = 'PARTIAL_SEARCH_HISTORY'A decode on DATA_TYPE field would allow you to add a format mask for DATE fields if necessary.

Convert string Column into set or Rows.

Hi,
I have a difficult time converting a string column in the source table to be spitted and insert them as individual rows in target table. The source sting is separated by "-" character. And the source sting can have any number of "-" which may result in any number of out put rows.
e.g. "- IL - NY - NJ - KY - TX" "RAY" should look like
RAY IL
RAY NY
RAY NJ
RAY KY
RAY TX
in the target table.
Thanks,
Ashvin.

This is working.
All you need to do in owb is pull the table function operator , config it take a ref-cursor and also give the attribute names that are declared in the type record to each of the out put variables in the table function operator.(in this case-8 variables).
Thanks,
Ashvin.
