Welcome to the forum!!! You can convert column to row like this
SQL>with my_table
2 as
3 (
4 select 'A' col1,'B' col2,'C' col3,'D' col4,'E' col5,'F' col6,'G' col7,'H' col8,'I' col9,'J' col10
5    from dual
6 )
7 select decode(no , 1, col1, 2, col2, 3, col3, 4, col4, 5, col5, 6, col6, 7, col7, 8, col8, 9, col9, 10, col10) col
8    from my_table
9    cross join (select level no from dual connect by level <= 10)
10 /
C

Need multiple lines in single column of header using alv oops

Hi
I am using alv oops in a report.
I need multiple lines in single column of header.
In header of my report i am using 9 columns.
In the second column i need to split the line
Notification description/activity/work/activity long text/
as
Notification description/
activity/
work/
activity long text/
Please guide me to achieve this functionality.

It is not possible to break the column description in the ALV disply.
Actually, if you have a longer description in one of the seltext_* field of the fiels catalog, it will automatically display it as a tooltip, if you put the mouse over the heading. In ALV OO, you can explicitly set the tooltip text.
Also you can get more help on the field pressing F1: If you use DDIC fields, it it automatic, otherwise you can do it as you like.

How to Concat multiple columns to single column at the report level

Hi All,
I have a requirement in such a way that I have to concat multiple colulmns to single column at the report level.
First of all the column I am using in my report is "X" with datatype as Integer. Now if the length of this column "X" is <8 then I have add zero's (0) before the number.
And then I have to concat with a column "Y" and then cocnat with a column "Z" and finally the datatype should be casted to CHAR.
Can anyone please let me know the logic how I can add to my column so that it satisfies all the above.
Thanks All

>Also, Another thing is if X < length of 8 Ihave to append with zero's..
>Ex: if the actual value of X is 123456 i wanted to show it as 000123456.
Try to be consistence what you said, you are looking for 8 length and above ex is 9 in length.
You need to learn many things one of those is CASE, at least do copy and also read

How to insert from one table to another (multiple columns to single column)

I want to insert data from table1 into table2 and the data looks in 3 columns as below
Table1
RepNm ObjNm DbNm
123     abc def
456     def xyz
789     123 456
and the data in table2 should be display as
Table 2
ObjNm
123
456
789
abc
def
xyz
the dupes should get eliminated and only the distinct values should be inserted into a single column in table2 from multiple columns in table1

How do you want to handle nulls? If there is a null in any value of a column, do you want to insert it?
Then,
WITH T
     AS (SELECT LEVEL colnum
           FROM DUAL
         CONNECT BY LEVEL <= 3)
SELECT DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) as ObjNm
FROM table1, T;if you dont want to insert nulls then,
WITH T
     AS (SELECT LEVEL colnum
           FROM DUAL
         CONNECT BY LEVEL <= 3)
SELECT DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) AS ObjNm
FROM table1, T
WHERE DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm) = DECODE (colnum, 1, RepNm, 2, ObjNm, 3, DbNm)G.

Merge multiple columns into single column?

Hi,
I need to execute queries dynamically and return the values. I need to fetch the values of the queries in single column only by concatenating the multiple columns. I cannot use PL/SQL in my scenario.
is there any way to execute a query and the result will be fetched in single column (values of multiple columns needs to be concatenated)?
Thanks,
Raja.

I have one query which is joining few tables and giving me output like below.

Indexes with multiple columns v/s multiple indexes with single column

Hi Everyone,
I have a table with below structure
Create Table Test_Table
Col1 int,
Col2 int,
Col3 int,
Col4 int,
Col5 int,
Col6 int,
Col7 int,
Col8 bigint
Col9 money
Col10 money
Now this table is being used in various reports. Since reports need various data, the filter clause for the report’s have various combination of table columns
Example, Report 1 can have query like
Select * from Test_Table where col1 = @val1
Report 2:
Select * from Test_Table where col1 = @val1 and col2 >=@val2
Report3:
Select * from Test_Table where col1 = @val1 and col2 >=@val2 and col3 =@val3 and col4 in(@val4)
Report4:
Select * from Test_Table where col1 = @val1 and col2 >=@val2 and col4 = @col4
And many more combinations.
Currently the table has many combinations of indexes
Index1: col1, col2
Index2: Col2
Index3: col1, col2, col4
Index4: col3 include (col9)
Index5: col1, col2, col3, col4, col9
Now I am into a performance issue where I have to create one more index with a slight variation from the existing combination of columns.
Can you please let me know instead of having these various combination of indexes can I create multiple indexes on individual columns.
Considering the above 4 examples which I have given for 4 reports, if I create 4 indexes separately on 4 individual columns col1, col2, col3, col4 will it be effective on all4 reports?
Please suggest me the best way to create indexes on this table
Thanks in advance,
Raksha

Do you really need to bring all columns ? Do not use SELECT *.
Just a guess try index on col1, col2, col3, col4

Collect Multiple Responses Into Single Column

I need a form that can collect multiple names and phone numbers and save the data in two columns. One column for names and one column for phone numbers.
How can I do this?

My form looks like this:

Phone:
Name:
Phone:
Name:
Phone:
So responses come in looking like this:
Name:          Phone:                 Name:          Phone:             Name:          Phone:

I need them to look like this:

Merging values of CKFs in two columns into single column

Hi ,
I want to merge values present in two different columns.The values present in rows of one column are not present in rows of other column, I have to merge the values into a single column.so that in the single column i can get all the values.how to do it in BEx.
regards ,
man.

Hi,
Dear murali , the solution you gave has helped me a bit as i am able to get the values for both the formula KF's in the same column,But another problem has arisen.
   For both the formula KF's I had to choose 'New Selection' (and not 'New formula')after R-cllick on the structure, as I had to use a Characteristic as restriction for Each of the KF's, and also to use the Characteristic I had to associate it with some KF so that the Characteristic wil be used as a KF in the formula.
   Now what is happening is that I am getting the values of that associated KF also in the empty rows.(i.e. the rows where the value of both the KF1 and KF2 is not present)
   What has to be done to remove them and keep the empty rows empty and not show the value of the KF taken with the Characteristic for restriction. Also its value is summing up with KF1 and KF2 in the coulmn which is having both KF1 and KF2 together.

Unique row based on two columns and single column

Dear Members,
I have a table which contains duplicate rows, for which a query should be able to fetch the unique row from the table. Here the unique is not based on one column, but it should be on two columns and also check for uniqueness on one column.
create table addr ( firstname varchar2(10), lastname varchar2(10), area varchar2(3));
insert into addr values('bob', 'james', '1');
insert into addr values('bob', 'james', '1');
insert into addr values('harry', 'bert', '1');
insert into addr values('jimmy', 'bert', '1');
insert into addr values('sam', 'mac', '1');
insert into addr values('sam', 'knight', '1');
insert into addr values('tom', 'sand', '1');
insert into addr values('cat', 'mud', '1');
The output of query should contain 3 rows.
bob - james
harry - bert or jimmy - bert [ either one of them, but not both ]
sam - mac or sam - knight [ either one of them, but not both ]
tom - sand
cat - mud
SELECT firstname, lastname as total from addr WHERE area = '1' GROUP by firstname,lastname; This does not take of single column duplication..
Any suggestions..

Not for that data, no. You have a set of characters with no information about 'order', so they could appear in any order.
If you had some numbering against them, you could pivot the data and concatenate them, but in truth even the concatenation symbol "||" is a built in function, as well as the functions needed to pivot it...
