sample my table test:
create table test (
     idsearch number,
     idtest number,
     p_nome varchar2(50),
     p_value varchar2(50),
     primary key(idsearch,idtest)
insert into test values(1,1,'name','alex');
insert into test values(1,2,'age','21');
insert into test values(1,3,'nick','alex');
select * from test;
return :
IDSEARCH IDTEST P_NOME P_VALUE
1 1 name alex

How to select rows whose one column contains some specific characters ?

These is a table say T1 with a column say C1
Let the field C1's values be:
row 1)DE/SPT/A/FWD
row 2)G/SPT/DE/DE/SPT
row 3)R/FWD/SPT/A/FWD/FWD
row 4)A/A/DE/SPT/FWD
row 5)FWD/SPT/E/DE/A
How to get only those rows whose C1 column contains FWD in last ?

We can solve this with the simple use of a wildcard:
    select *
    from t1
    where c1 like '%FWD'
    /Note that this query will execute a full table scan, because any index you may have on C1 will be ignored: indexes are organised on the leading characters.

Returning two rows with one column containing only one place

Dear all;
I have a query that returns two rows similar to this below
ID      PLACE            PROGRAM
A       NEWYORK      PROGRAM A
A       NEWYORK      PROGRAM B
I would like this instead
ID      PLACE             PROGRAM
A       NEWYORK       PROGRAM A
                               PROGRAM B

WOW...THanks a lot Solomon, I have never used partitions and row_number in such a manner...can you please explain your logic.Sure:
row_number() over(partition by id order by place,program)This will take all rows returned by the query andsplit them into buckets (partitions) by id. Inside each bucket it will order rows by place and program and assign them row numbers. So for each ID row number 1 will be row with first (alphabetically) place first programt. And this is the row where we want ID to show up. That is why we wrap the above analytic function in CASE statement which will do exactly that. Now:
row_number() over(partition by id,place order by program)does pretty much the same just bucket is ID and PLACE combination. So for each such combination we want to show only for the first (alphabetically) programt.
Now notice in ORDER BY clause I prefix ID and PLACE with table alias. You must do it since otherwise query alias ID and PLACE will take precedence resulting in wrong sort order (remember we nulled all ID and PLACE except for row number 1).

Dynamic table - some fields of different rows in one column

Hey guys,
i have the following problem:
i habe a itab with some data like:
name | id | date | number
pete | 1 | 27.07 |    2
pete | 1 | 28.07 |    2
pete | 1 | 30.07 |    2
ann   | 1 | 28.07 |    3
ann   | 2 | 30.07 |    2
the user can define a period of time, e.g. 28-29.07
so my dynamic table will consist of the "hard" columns name and id and the dynamic added columns for every day:
name | id | 28.07 | 29.07
that's what i already have!
so my problem is, that i have to read the data from the itab into the new dynamic table (field-symbol) like:
name | id | 28.07 | 29.07
pete   | 1 |    2     |    2
ann    | 1 |    3     |    -
i hope you can understand what i want! please give me code sample or a example report!
many thanks in adance!

after the loop, the 4 rows should be in my field-symbol only one row (no sum)!
but after the loop, there are to many rows! only one row is needed!
Look at the screenshot:

So the second row at column "tag20080801" should be initial and with the next loop, the next day "tag20080730" should be filled with the number!

Group by returning more than one column in a single query

Hello,
Sorry to ask such a simple question I guess, but here is my problem.
I'm building a query to get say the smallest user_id from employees in the company by department.
The query goes like :
select emp..department,
min(emp.user_id)
from employee emp
group by emp.department
This gives me the smallest user id by department, which is what I want. But how can I also get the name of that person ?
I know that the "min" condition singles out a unique record (there are no two persons with the same user_id in the department).
But how can I also get the name without turning the above query in a subquery that I would link to the employee table yet again ?
I know the following works but I don't think it's the best option:
select v1.department,
v1.user_id,
emp1.name
from employee emp1,
( select emp..department,
min(emp.user_id)
from employee emp
group by emp.department) v1
where emp1.user_id = v1.user_id
This is just an example of data. It is the principle that I don't quite get.
Any advice would be very much appreciated.
Cyril

Hi, Cyril,
To find the name of the person who has the lowest user_id
SELECT    department
,         MIN (user_id)   AS lowest_user_id
,         MIN (name) KEEP (DENSE_RANK FIRST ORDER BY user_id) AS person_with_lowest_user_id
FROM      emp
GROUP BY department;"MIN (name)" above means that if there is a tie for the lowest user_id, then the contender with the first name will be chosen.
If you want to display several columns from the row with the lowest user_id, you have to have a separate "KEEP (DENSE_RANK ...)" expression for each column. In that case, you may find it easier to use the analytic RANK or ROW_NUMBER in a sub-query, like this:
WITH sub_query AS
     SELECT department
     ,     user_id
     ,     name
     ,     col2, col3, col4, col5
     ,     RANK () OVER ( PARTITION BY department
                           ORDER BY          user_id
                    ) AS r_num
     FROM     emp
SELECT     *     -- or list all columns EXCEPT r_num
FROM     sub_query
WHERE     r_num = 1;

Highlight complete row if one column is null

Hi,
i want to highlight a complete row in my publisher report if a certain column of the
row is empty (no value at all). I already tried to get forward using the examples in the
XML Publisher developer guide (i checked the samples installed by xml publisher desktop
as well) but none of them delivered the desired result.
Any hints are welcome.
regards
Thomas

Hi,
You can write the following code to highlight a row if a certain column is null:
<?if@row:COLUMN-NAME=''?><xsl:attribute name="background-color" xdofo:ctx="incontext">red</xsl:attribute><?end if?>
You can place this code in a text form field and place in the first column after the for-each statement.
Hope this helps.
Thanks.

Hi,
That's called String Aggregation. This page:

shows several ways to do it.
Which way is best for your data ,your requirements and your version of Oracle? That depends on your data ,your requirements and your version of Oracle.
LISTAGG is especially useful.

Search one column for value in another column

Hello,
I am trying to take the whole value from one column, and see if that string appears anywhere in another colmn. So if one row in one column has the value "cat", I want to see if that string appears anywhere in any row in another column: so a row with the value "The cat sat on the mat" would return true.
I have tried:
select term from pic_lib_keywords, csv
where contains (csv.nhm_field_asset_description,pic_lib_keywords.term) >0;
But I get the error:
ORA-20000: Oracle Text error:
DRG-50901: text query parser syntax error on line 1, column 32
20000. 00000 - "%s"
*Cause:    The stored procedure 'raise_application_error'
was called which causes this error to be generated.
*Action:   Correct the problem as described in the error message or contact
the application administrator or DBA for more information.
Can you use 2 columns in this way, or does the search term have to be a literal? Any suggestions would be appreciated.
Thank you.

DataGrid alternating row colors per column

Is there a way to set different alternating colors to each
column in a DataGrid. I have a datagrid where I want two of the
columns to have different alternating row colors, one column (red
and light red) and the other (green and light green).
Many thanks

You can simply set the DataGridColumn property to the
approprate colors.
ex.
<mx:DataGrid y="0" x="0" width="100%">
<mx:columns>
<mx:DataGridColumn id="col1" backgroundColor="0x640000"
dataField="col1"/>
<mx:DataGridColumn id="col1" backgroundColor="0xFF0000"
dataField="col1"/>
<mx:DataGridColumn id="col1" backgroundColor="0x006600"
dataField="col1"/>
<mx:DataGridColumn id="col1" backgroundColor="0x33CC33"
dataField="col1"/>
</mx:columns>
</mx:DataGrid>
or you can use the setStyle:
col1.setStyle("backgroudColor", 0x640000)

Dropdownbykey. data is missing in one column

Hi,
I am facing issue in dropdownbykey UI element.
When pushbutton is clicked, there is table showing up. but the first column in the table is missing. There is no value. This column values are expected to be like hyperlink so that when any one is clicked that is selected and the field is populated by this value.
I have found the dropdownbykey UI element on the view and trying to find the code for this UI element.
I dont know anything about the dropdownbykey ui element as i am new to web dynpro. I am reading the sap help material but its not addressing very basic understanding
Could you please help get answers to following
1) When we click pushbutton of dropdownbykey ui element we see a table from which we can click on one of the rows (only one column of the table is link which we can click) How are the columns in the table determined ?
2) Which key of the table is selectable ?
3) From where are the values of the table fetched ? u2013 backend. so obviously will have to pick data type linked to the ui element from some model rite ? it cant be string.
4) Why is there a value-set ? is it for the dropdown part of the ui element ? is it mandatory to code them as contants when we make a ui element dropdownbykey on our view or there is any other way of fetching this value-set data?
thank you

Hi Yogesh,
Its perfectly alright.
Could you please tell me what is SVS code ?
Is it so that by using this I will have all the methods needed for coding required for dropdownbykey ui element ?
I dont want to go by dropdownbyindex because I am not developing any application, there is this problem in an already developed application which I have to investigate
My above questions were based on understanding that when we include dropdownbykey ui element in our view , the dropdown list, pushbutton and screen with all values are inbuilt. This is written in the sap help on the link -
http://help.sap.com/saphelp_nw04/helpdata/en/5c/1b76bc3da0504e8b535cf3e154eaa7/frameset.htm
But now I have seen in my system that there is actually a separate view for displaying values is created for the pop up.
there is linktoaction ui element in the view where the dropownbykey is put and this linktoaction calls the view for displaying values.
I am now checking inside the code which passes data to this pop up view , why the first column in the table is missing.
thanks

Update column with subquery returning more than one row

Hi Everybody,
Please let me know how to handle this. I am writing update statement in procedure with subquery and it is returning multiple rows. Please help me, how i can handle this :
UPDATE TABLEA A
SET A.ERROR_MESSAGE = (Select B.XERROR_MESSAGE from TABLEB B, TABLEA A WHERE B.id = A.id)
WHERE A.id = (Select B.id from TABLEB B, TABLEA A WHERE B.id = A.id);
(Select B.XERROR_MESSAGE from TABLEB B, TABLEA A WHERE B.id = A.id) --- This subquery is returning more than one rows. How i can handle this in Pl/SQL?
Please let me know. I will be very thankful to you all.
I will really appreciate your replies and comments.
Thank you

Try getting rid of tablea in your subqueries. You already have it in the UPDATE statement.
UPDATE TABLEA A
SET    A.ERROR_MESSAGE = (Select B.XERROR_MESSAGE
                          from   TABLEB B
                          WHERE B.id = A.id
WHERE A.id = (Select B.id
               from   TABLEB B
               WHERE B.id = A.id);You can also try a simple MERGE:
merge into tablea a
using tableb b
on    (a.id = b.id)
when matched then update
      set a.error_message = b.xerror_message;
