Merge multiple rows of same ID into Single row

Hi All,
I need the requirements of merging multiple rows of same ID as single row.
My Table Data:
ID     Language1 Language2 Language3 Language4
1001 NULL         JAPANESE NULL          NULL
1001 SPANISH   NULL          NULL          NULL
1001 NULL        NULL           NULL         ENGLISH
1001 NULL        NULL           RUSSIAN    NULL
Required Output Should be,
ID     Language1 Language2 Language3 Language4
1001 SPANISH    JAPANESE RUSSIAN   ENGLISH
Please help me to achieve this output.
Tried grouping but its not working also producing the same result.
Thanks.
Live freee....Joy forever................ :)

Try the below:
create Table Test_Sample(ID int,Language1 varchar(50), Language2 varchar(50), Language3 varchar(50), Language4 varchar(50))
Insert into Test_SAmple Values(1001,NULL,'JAPANESE', NULL, NULL),
(1001,'SPANISH', NULL, NULL, NULL),
(1001,NULL, NULL, NULL, 'ENGLISH'),
(1001,NULL, NULL, 'RUSSIAN', NULL)
Select ID,MAX(Language1),MAX(Language2),MAX(Language3),MAX(Language4)
From Test_Sample
Group by ID
Drop table Test_Sample

Merging multiples of the same photo into one

I remember reading a couple tutorials on how to do this weeks ago, but now i cannot seem to remember what to search for to find a tutorial on this.
I multiple photos, its the same location (tripod) with me in a different position in each frame. I want to merge each frame into one picture so in one picture there are multiples of myself in different positions.
thanks!

You'll have to use File->Scripts->Load Files into Stack to load all the images into a single document, each on it's own layer, select all the layers and go to Edit->Auto-Align Layers. If all went well then you should be able to achieve your effect using a couple of simple layer masks

If you understand how SQL statements are executed it's along these lines...
1. Open Cursor
2. Parse SQL statement and determine columns
3. Bind in any input values
4. Fetch data
5. Bind out values to columns
6. Repeat step 3 until no more data
7. Close cursor
Now, you're expecting that you can determine the columns (step 2) from the fetched data (step 4 onwards). You can't. The SQL engine needs to know the expected columns before any data is fetched so, it can't base the number of columns on the data itself.
If you need that requirement, you would need to query the data first and build up a dynamic query based on the data and then execute that dynamically built query to fetch the data and pivot it into those columns, which means that you have queried the data twice. Not good practice and not good (or simple) coding.
What you're talking of doing is something that should be handled at the presentation/interface layer, not as part of the data fetch.
Typically these sorts of things are handled most easily in report generation/writer tools such as Oracle Reports, Business Objects etc. where they fetch the data from the database and then process it to format it on the display, pivoting the results as required.
It's not something that lends itself to be easily achieved in SQL. Yes, SQL can do pivoting of data quite easily, but NOT with a dynamic number of columns.
If you were to specify that there is a maximum number of columns that you could get (rather than wanting it dynamic), then you can do it simply in SQL with the max-decode method...

Merge multiple rows into single row (but multiple columns)

How to merge multiple rows into single row (but multiple columns) efficiently.
For example
IDVal IDDesc IdNum Id_Information_Type Attribute_1 Attribute_2 Attribute_3 Attribute_4 Attribute_5
23 asdc 1 Location USA NM ABQ Four Seasons 87106
23 asdc 1 Stats 2300 91.7 8.2 85432
23 asdc 1 Audit 1996 June 17 1200
65 affc 2 Location USA TX AUS Hilton 92305
65 affc 2 Stats 5510 42.7 46 9999
65 affc 2 Audit 1996 July 172 1100
where different attributes mean different thing for each Information_type.
For example for Information_Type=Location
Attribute_1 means Country
Attribute_2 means State and so on.
For example for Information_Type=Stats
Attribute_1 means Population
Attribute_2 means American Ethnicity percentage and so on.
I want to create a view that shows like below:
IDVal IDDesc IDNum Country State City Hotel ZipCode Population American% Other% Area Audit Year AuditMonth Audit Type AuditTime
23 asdc 1 USA NM ABQ FourSeasons 87106 2300 91.7 46 85432 1996 June 17 1200

Hi,
That's called Pivoting . The forum FAQ has a section on this subject: {message:id=9360005}
I hope this answers your question.
If not, post your best attempt, along with a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and also post the results you want from that data. (You did post the results you wanted, but they're very hard to read because they're not formatted. Use \ tags, as described in the forum FAQ, below.)
Explain, using specific examples, how you get the results you want from the data given.
Always say which version of Oracle you're using (e.g., 11.2.0.2.0). This is always important, but especially so with pivots.
See the forum FAQ {message:id=9360002}

How to display multiple lines of texts in a single rows in ALV

Hi,
I have a unique requirement in which i have to display multiple lines if texts for a single rows in ALV Grid. Right now in my output it is coming in single line which is not visible fully because that text is more than 255 character. So i want to display the test by splitting into multiple lines and show it on output. Please suggest some solution for this if this is possible in ALV.
Thanks,
Raghav

Hi Raghavendra,
Its not possible to display multiple line in one row of an alv, but i think you can acheive it by splitting the whole text into multiple sub-text.
For example, if your requirement is as below:
Field #1          Field #2
1                    xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx(200 characters)
2                    yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy(220 character)
then you can break Field#2 value into say 50 character and then populate the internal table with repetative entries of Field#1 and the finally sort it by Field#1 value... as a result of which you output will be somewhat as below:
Field#1          Field#2
1                   xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
                     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
                     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
                     xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
2                   yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
                     yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
                     yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
                     yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy
                     yyyyyyyyyyyyyyyyyyyy
Hope it will help you in meeting your requirement.
Regards,
Shradha

How to merge multiple XML or Text documents into 1 Word Document?

Hi all,
We're looking for a way to merge multiple XML or Text documents into 1 Word document.
All the XML or Text documents are oriented as a 'Paragraph', meaning smaller pieces of text.
By selecting some of these XML documents, the system should be able to create a new Word document with all the selected text paragraphs included.
The Word document can then be edited for applying a correct lay-out and the document is ready.
Actually, we are trying to do some kind of 'mail merge' but with multiple XML or Text documents!
Has anybody an idea whether something exist already or give us a direction how to proceed?
Thanks in advance,
Pascal Decock

You use Assembler for this purpose.
1) Assembler can be accessed through LC Java API. See http://help.adobe.com/en_US/enterpriseplatform/10.0/programLC/help/index.html
API Quick Starts (Code Examples) > Assembler Service API Quick Starts
2) Last week I posted on generating and merging PDF's from PostScript. Take a look at the assembly service instance in the .lca. Assembler uses DDX (Document Description XML) to describe document construction. NOTE the .lca was developed with ES 3 (aka ADEP). The .lca It contains the most basic DDX.

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

Want to be able to open tabs in multiple rows, rather than in a single row. I used tab mix plus before, but it says it is not compatible with New tab Homepage. The older version of Firefox allowed this very easily.

ALV - Multiple Rows into Single Row

I have a requirement to display the ALV output from CDHDR&CDPOS tables here in the output i have 15 columns( Fields ) any changes im displaying in report output ,but if there is same time multiple columns will change im displaying as individual record instead of that i need to show as single row.
in this output last three records have same time change but i have populated into three different columns i want to make it as SINGLE Row Record.
Thanks!!

We don't need script task for this. Use TSQL in the datasource. Refer below example
DECLARE @TEMP TABLE(ID INT, [VALUE] NVARCHAR(30))
INSERT INTO @TEMP VALUES(1 , 'MAZ')
INSERT INTO @TEMP VALUES(1 , 'HON')
INSERT INTO @TEMP VALUES(1 , 'FOR')
INSERT INTO @TEMP VALUES(2 , 'JEEP')
INSERT INTO @TEMP VALUES(2 , 'CHE')
INSERT INTO @TEMP VALUES(3 , 'NIS')
INSERT INTO @TEMP VALUES(4 , 'GMC')
INSERT INTO @TEMP VALUES(4 , 'ACC')
INSERT INTO @TEMP VALUES(4 , 'LEX')
SELECT [id],
Stuff((SELECT ',' + [VALUE]
FROM @TEMP
WHERE [id] = a.[id]
FOR xml path('')), 1, 1, '') [VALUE]
FROM @TEMP a
GROUP BY [id]
