Contatenate Rows Into One

Hi,
I have a table with different columns as follows
Select * from test
where ID=123456;
     ID     LINE_COUNT     CONTACT_DATE     CONTACT_COMMENT
     123456     1          01/21/2008     I want to Join This Line 1
     123456     2          01/21/2008     With This Line 2
     123456     3          01/21/2008     and this line and following lines to make 1 line
     123456     4          01/21/2008     ?
     123456     5          01/21/2008     ?
     123456     6          01/21/2008     ?
How Can I write a SQL to get the following output:
ID     CONTACT_DATE     CONTACT_COMMENT
123456     01/21/2008     I want to Join This Line 1 With This Line 2 and this line and following lines to make 1 line

Merging rows into one row but into SEPARATE Columns

Hello Gurus,
I have searched alot on OTN and many other places, but no where I could get the solution of how can we merge rows into one row but separate column. For example
Consider the below scenario
"DEPARTMENT", "EMP","NAME","SUBJECT"
"Electronics","1","Sam","LIC"
"Electronics","2","Pam","VLSI"
"Electronics","3","Tom","C"
"Mech","1","Abu","Thermo"
"Mech","4","Lina","Machines"Now, I need the output like
Based on Department as Group By Clause
"DEPARTMENT", "EMP1","NAME1","SUBJECT1","EMP2","NAME2","SUBJECT2","EMP3","NAME3","SUBJECT3"
"Electronics","1","Sam","LIC","2","Pam","VLSI","3","Tom","C"
"Mech","1","Abu","Thermo","4","Lina","Machines"
The row data to be loaded into separate columns. Name of the column is not an issue... can be anythingIn all the forums which I went through I could find them loading into a single column, but not into respective separate columns.
Any help would be much appreciated.
Thanks

Frank,
I saw your name nearly n number of times, as I went through many forums today... And the link which you have just posted, I went through it today afternoon.
Could you please explain this bit taken from your dynamic pivot post.
SELECT     DISTINCT
     ',     COUNT (CASE WHEN job = '''
||     job
||     ''' '     AS txt1
,     'THEN 1 END)     AS '
||     job
||     '_CNT'     AS txt2
FROM     scott.emp
ORDER BY     txt1;Many Thanks.You only need that when you need column aliases based on the actual data (and you explicitly said you don't need that) or when can't put an upper bound on the number of columns to be displayed. If that doesn't apply to this problem, then don't use any kind of dynamic SQL (like the code above); it makes the job much more difficult, less efficient and less robust.
Here's what the code above is doing.
If you were hard-coding a query that showed the number of people in each job, and you knew that the possible jobs were 'ANALYST', 'CLERK' and 'MANAGER', then you might hard-code a query like this:
SELECT    deptno
,       COUNT (CASE WHEN job = 'ANALYST' THEN 1 END)     AS analyst
,       COUNT (CASE WHEN job = 'CLERK'    THEN 1 END)     AS clerk
,       COUNT (CASE WHEN job = 'MANAGER' THEN 1 END)     AS manager
FROM       scott.emp
GROUP BY deptno
;If the jobs had different names, or if there were not 3 different jobs, then you would have to change the lines in the SELECT clause that start with ", COUNT ( CASE ...".
The code you posted is from an example of dynamic SQL, where you first run a Preliminary Query . (What you posted above is, in fact, the complete preliminary query.) The output of that preliminary query is exactly the variable part of the real query, such as:
,       COUNT (CASE WHEN job = 'ANALYST' THEN 1 END)     AS analyst
,       COUNT (CASE WHEN job = 'CLERK'    THEN 1 END)     AS clerk
,       COUNT (CASE WHEN job = 'MANAGER' THEN 1 END)     AS managerYou then use this output as part of your main query. In other words, you can write something today that will generate exacrly as many columns as you need next year, with names from the data as it is next year. How? because you're not writing the full query today. The variable part will be written by the preliminary query when it runs next year.

How to coalesce many rows into one?

I am using SSMS 2008 R2 and am simply trying to coalesce many rows into one. This should be simple I think, but it is currently repeating data in each row. Consider:
create table test
Name varchar(30)
insert test values('A'),('B'),('C')
select * from test
select distinct Name, coalesce(Name + ', ', '')
from test
How can I rewrite this to achieve one row like: A,B,C
Ryan D

Or as a variation
Declare @S varchar(MAX)
set @S = ''
select @S = @S + ', ' +Name
from test
Select substring(@s, 2, length(@s))
Would be interested to know performance difference between this style and the XMLPath used by Naomi though. The XMLPath technique certainly looks cleaner
A samll correction for RyanAB's solution:
Select substring(@s, 2, len(@s))

A way to roll up rows into one row

Is there a way to "roll up" a set number of rows into one row? I would like to have a row that can be expanded into several rows by clicking a plus sign or something similar. Anyway to do this?
Regards,
Mark

Mark,
Sorry, it didn't occur to me that you meant "hiding". It sounds like you already know how to hide and unhide but unfortunately there are no shortcuts. I agree that it would be nice to have a way to unhide a selected row or column and if my memory serves me I submitted a request for this feature some months ago. May I suggest that you also go to Main Menu > Numbers > Provide Numbers Feedback.
The more requests for features they receive the better the chance for getting them in future updates. Best wishes,

Consolidating three rows into one

Hello,
I am struggling to figure this out and my googling hasn't quite led me to what I need. I have found some ideas such as sys_connect_by_path but I want to convert my three rows into columns (using one row), not concatenate them. I can not quite find the right thing or work it out. The code below gives me the columns I want but I can not figure out how to consolidate it onto one row. When I uncomment the group by line it doesn't like it as the role and emp fields are not group expressions. The values I wish to pivot are strings and not numbers (role).
Would anybody be kind enough to help?? my brain has frozen!! :D
Thanks very much

Combining multiple rows into one row

Hi all.
My most humble apology for this question but solutions in previous threads did not seem to help much.
Apparently, my account has not been verified and I am currently at home with no access to the SQL code so i can't post the actual code.
We have this (mockup) of code
Select S.C1, AViewSS.Study, AViewSS.SlotName, IST.TakenByDate, IST.ScannedByTime, SE.TimepointCalculation
From IST
INNER JOIN
AViewSS ON IST.GroupID = AViewSS.GroupID and
IST.SlotID = AViewSS.SlotID
INNER JOIN
S ON AViewSS.StudyID = S.StudyID
INNER JOIN
SE ON IST.Line = SE.Line and IST.SubLine = SE.SubLine and
AViewSS.ScheduleID = SE.ScheduleID
WHERE
(IST.GroupID = 92) and (IST.SlotID between 1791 and 1795)
and (AViewSS.VisitID = 137)
The query currently returns this result set
Col 1   Col 2   Taken Date Date 1                Date 2               Date 3
Scanned DateTime
Data    Data    3/12/2015 3/12/2015 7:22
        3/12/2015 7:22
Data    Data    3/12/2015                            3/12/2015 8:47
3/12/2015 8:47
Data    Data    3/12/2015
3/12/2015 9:27 3/12/2015 9:27
Data    Data    3/22/2015                            3/22/2015 7:27
                 3/22/2015 7:27
Data    Data    3/22/2015
Data    Data    4/12/2015
Data    Data    4/12/2015
Data    Data    4/12/2015
You’ll notice that rows 1, 2, 3 are related as are rows 4, 5 and rows 6, 7, 8.
This is what we ultimately want to see given the results above.
In the report, rows 1, 2, 3 from the results should roll into one row with the ScannedByTimeStamp from each row returned by the query populating the appropriate report time column based on the value of a column in the row.
Col 1   Col 2   Taken Date Date 1                  Date 2
Date 3
Data    Data    3/12/2015 3/12/2015 7:22    3/12/2015 8:47   3/12/2015 9:27
Data    Data    3/22/2015                               3/22/2015 7:27
Data    Data    4/12/2015
We would appreciate any guidance.

Hi Duane,
The table and matrix data regions can display complex data relationships by including nested tables,matrices, lists, charts and gauges. Tables and matrices have a tabular layout and their data comes from a single dataset, built on a single data source. The
key diference between tables and matrices is that tables can include only row groups, where as matrices have row groups and columns groups.

Merging 2 rows into one

Greedings,
I have the following output
1       A       null     null
2      null      B         CHow is it possible to merge it into one line?
CREATE TABLE test_g
a VARCHAR2(1),
b VARCHAR2(1),
c VARCHAR2(1)
INSERT INTO test_g
VALUES (null,'B','C');
INSERT INTO test_g
VALUES ('A',null,null);

what you are asking of is a kind of Grouping?
If yes, you need to have a Grouping Trait, that stays common across the rows to be grouped.
Extending your example:
create table test_t (grp varchar2(5), col_a varchar2(5), col_b varchar2(5), col_c varchar2(5));
insert into test_t values ('A', 'A', null, null);
insert into test_t values ('A', null, 'B', null);
insert into test_t values ('A', null, null, 'C');
insert into test_t values ('B', 'B', null, null);
insert into test_t values ('B', null, null, 'D');
select grp, max(col_a), max(col_b), max(col_c)
from test_t
group by grp;
GRP   MAX(COL_A) MAX(COL_B) MAX(COL_C)
A     A          B          C
B     B                     D          If you do not have a Grouping Trait, then you can still simply merge the rows. To do this, remove the GRP column from Select and group by from above query; which I think answers your original question. However, would you want to club the data of entire table into a Single row? If not then you need a Grouping column (as demonstrated above).

Concatenate strings from more rows into one row.

Hi,
what's the name of that analytical function (or connect by) that
would return strings from more rows as one row concatenated. i.e.:
(I know this is possible using regular pipelined functions.)
ROW1:   STR1
ROW2:   STR2
ROW3:   STR3
select tadah().... from ...
result:
ROW1: STR1 STR2 STR3Thanks.

Hi,
Here's a basic example of SYS_CONNECT_BY_PATH.
The query below produces one row of output per department, containing a list of the employees in that department, in alphabetioc order.
WITH     got_rnum     AS
     SELECT     ename
     ,     deptno
     ,     ROW_NUMBER () OVER ( PARTITION BY deptno
                                     ORDER BY         ename
                          ) AS rnum
     FROM     scott.emp
--     WHERE     ...          -- Any filtering goes here
SELECT     deptno
,     LTRIM ( SYS_CONNECT_BY_PATH ( ename
                              , ','     -- Delimiter, must never occur in ename
           )          AS ename_list
FROM     got_rnum
WHERE     CONNECT_BY_ISLEAF     = 1
START WITH     rnum          = 1
CONNECT BY     rnum          = PRIOR rnum + 1
     AND     deptno          = PRIOR deptno
;Output:
.   DEPTNO ENAME_LIST
        10 CLARK,KING,MILLER
        20 ADAMS,FORD,JONES,SCOTT,SMITH
        30 ALLEN,BLAKE,JAMES,MARTIN,TURNER,WARDThe basic CONNECT BY query would produce one row per employee, for example:
.   DEPTNO ENAME_LIST
        10 ,CLARK
        10 ,CLARK,KING
        10 ,CLARK,KING,MILLER
        20 ,ADAMS
        20 ,ADAMS,FORD
...The WHERE clause: <tt>WHERE CONNECT_BY_ISLEAF = 1</tt> means that we'll only see the last row for every department.
SYS_CONNECT_BY_PATH (which is a row function, by the way, not an analytic fucntion) puts a delimiter (',' in the example above) before every item on the list, including the first one.
The query above uses LTRIM to remove the delimiter at the very beginning.
WM_COMCAT (or the equivalent user-defined STRAGG, which you can copy from AskTom) is much more convenient if order is not important.

How to combine data from two rows into one row

I have the following sets of data. I want to find all the duplicate sets of field values. in the data below there is only one duplicate set: brenda, analyst, green.
DocID and Doc Seq combine to form the set key. FieldID I believe are consistent in that 1 is always name, 2 is job, 3 is favorite color etc. but there are up to 20 field IDs.
To tell you the truth, my client is a bit sketchy about the data and the values. I would like collapse the sets by getting all the field values into a single row. They could be in the same column, or in their own columns. This way I can then look for whatever
dups my customer seems to think that he has.
the first image is what i want (either in same column or in different columns. but they have to be in the order of the FieldID), the second is what i have. THANKS
