Dynamic display of columns in pivot query

I have a table called STUDENT_SCORE . I need to display the avarage score /month for past 2 years and the monthly score till today' month.
So suppose this is April 2009. The report will look like
Roll_id 2007avg 2008avg Jan09 Feb 09 Mar09
101 80.9 70.9 89.7 56.8 90.9
102 70.9 23.9 87.2 90.0 76.8
I have tried a bit , but can not fix the display of monthly score dynamically.
the DDL/DML is as below
create table STUDENT_SCORE
(roll_id number,
mth_id date,
score number) ;
insert into STUDENT_SCORE values
(101, to_date('01/01/2006', 'mm/dd/yyyy') , 67.5);
insert into STUDENT_SCORE values
(101, to_date('02/01/2006', 'mm/dd/yyyy') , 77.5);

Dynamically display/hide columns according to user inputs

Hi,
I need to display or hide columns in reports based on user input. ie. I have several prompts, if user doesn't input values, then the associated columns will not be displayed in the report. Is there a way to achieve this in BO XI R2. Greatly appreciated for your help.

Hi Andy,
You can't hide them totally, but you can get close using alerters.
Build an alerter (probably a formula one) that put the value ="" in the field.
Now the formula should test the userresponse for that column,
based on the contents of it (filled in --> false, otherwise --> true).
Apply the alerter to all cells of the column. It will empty completely when the prompt was not filled.
Just set the width of the column to automatic (best use the header cell only) and the minimum width on zero. It will shrink the width when empty, making it seem as if hidden.
Good luck,
Marianne

Dynamic selection of columns in report and print the output

Hi,
I tried to have dynamic selection of columns in SQL query using lexical parameter. The hitch is how to print those selected column in excel ouput ?
Suppose
I have select &col from table_name
Initial value of &col is col1 and in data layout only col1 appears
where &col was replaced with more than a column (col1,col2,col3)
now how to print the column selected at the run time,
i have coded in Before Report Trigger
:cell_val := ' <td><rw:field id:"cl1" src="col1"></rw:field></td>
<td><rw:field id:"cl2" src="col2"></rw:field></td>
<td><rw:field id:"cl3" src="col3"></rw:field></td> ' ;
and this user parameter was replaced in web source using JSP expression
<rw:getvalue id: "v_cell" src:"cell_val"></rw:getvalue>
<rw:foreach src:"g_val">
<table>
<tr>
<% =v_cell%>
</tr>
</table>
</rw:foreach>
but in the output i can see only blank columns
Regards
Suresh

The strings replaced by expression <%= v_cell %>
should print the field values contained in col1,col2,col3 columns, but nothing is printed . i think the custom tags (rw...) are not replaced by the jsp expression properly.

Setting Column Names in Dynamic Pivot Query

Hi all,
I'm having trouble setting column names in a dynamic pivot query and was wondering if someone could please help me figure out what I need to do.
To help you help me, I've setup an example scenario in my hosted account. Here's the login info for my hosted site at [http://apex.oracle.com]
Workspace: MYHOSTACCT
Username : DEVUSER1
Password : MYDEVACCTAnd, here is my test application info:
ID     : 42804
Name   : dynamic query test
Page   : 1
Table 1: PROJECT_LIST         (Alias = PL... Listing of Projects)
Table 2: FISCAL_YEAR          (Alias = FY... Lookup table for Fiscal Years)
Table 3: PROJECT_FY           (Alias = PF... Intersection table containing project fiscal years)
Table 4: PROJECT_FY_HEADCOUNT (Alias = PFH... Intersection table containing headcount per project and fiscal year)Please forgive the excessive normalization for this example, as I wanted to keep the table structure similar to my real application, which has much more going on.
In my sample, I have the "Select Criteria" region, where the user specifies the project and fiscal year range that he or she would like to report. Click the Search button, and the report returns the project headcount in a pivoted fashion for the fiscal year range specified.
I've got it working using a hard-coded query, which is displayed in the "Hardcoded Query" region. In this query, I basically return all years, and set conditions on each column which determines whether that column should be displayed or not based on the range selected by the user. While this works, it is not ideal, as there could be many more fiscal years to account for, and this is not very dynamic at all. Anytime a fiscal year is added to the FISCAL_YEAR table, I'd have to update this page.
So, after reading all of the OTN SQL pivot forums and "Ask Tom" pivot thread, I've been able to create a second region labeled "Dynamic Query" in which I've created a dynamic query to return the same results. This is a much more savvy solution and works great; however, the column names are generic in the report.
I had to set the query to parse at runtime since the column selection list is dynamic, which violates SQL rules. Can anyone please help me figure out how I can specify my column names in the dynamic query region to get the same column values I'm getting in the hardcoded region?
Please let me know if you need anymore information, and many thanks in advance!
Mark

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

Displaying dynamic columns in the query output.

Hello,
Depending on current quarter output of the query would vary.
If current quarter is 'Q1'
O/p : InvQ1 Del BackQ1 BackQ2 BackQ3 BackQ4
If current quarter is 'Q2'
O/p : InvQ1 InvQ2 Del BackQ2 BackQ3 BackQ4
If current quarter is 'Q3'
O/p : InvQ1 InvQ2 InvQ3 Del BackQ3 BackQ4
If current quarter is 'Q4'
O/p : InvQ1 InvQ2 InvQ3 InvQ4 Del BackQ4
So, out of 9 columns, 6 columns would display at any given time depending on the current quarter.
Invoice of 4 quarters, Deliquency and Backlog of 4 quarters.
I am not getting any way how to display dynamic columns or hide unwanted/blank columns.
For the time being I have added all 9 columns in the query, and in the output unwanted columns shows blank.
Can anybody please suggest me how to display only 6 columns in the output depending on current quarter.
Thanks and Regards
Shilpa

Hello,
This shouldn't be too difficult. Assuming you have a variable with the selected quarter, you may choose to display Inv (whatever that is) for quarters 1 through variable, Del, and Back for quarters variable through 4. You also need a drilldown on quarter in the columns (after the key figure structure). You would probably need to restrict 'Del' on the variable as well if you haven't already done it.
Best regards,
Christoffer

How can I display multiple column results of a sql query?

I'm wanting to display the results of a query selecting from multiple columns, but I can't seem to find an item type that will allow this. I've tried LOV, multiselect, display as text and others. Any ideas on how to do this. Here is my basic query:
Select ul.meaning,
rqa.submission_date,
rqa.location_num
from
cfa_rqa_doc_submit_dates rqa,
cfa_user_lookups ul
where
rqa.location_num in (Select location_num from cfa_current_locations_mv
where operator_person_id = :P1_PERSON_ID and substr(location_num,1,1) = '8')
and
ul.lookup_type_id='1269'
and
to_char(rqa.submission_date, 'month') = to_char(sysdate, 'month')
and
rqa.submission_date >= (SYSDATE-365)
and ul.lookup_ID= rqa.document_type_id
;

Hi,
Do you just wish to display the result of the query? If so, you can simply parse it out in HTML.
You can then choose if you want to use tables or css.
Multiple column layout in tables are based on <tr> and <td>.
<tr> is a table row, where <td> is a column.
All tags should be closed.
Example:
<table>
<tr>
<td>col1</td><td>col2</td>
</tr>
<tr>
<td colspan="2">spans over 2 cols</td>
</tr>
</table>If you want to do the same in css:
(Seems this forum removes the styles!):
float:left; width:50; << first div and 2 div (col 1 and col 2 style)
float:left;clear:both; width:100%; << clear both, double width (spans over 2)
<div>
<div style="float:left; width:50;">col1</div><div style="float:left;width:50%;">col2</div>
<div style="float:left;clear:both; width=100%;">Spans over 2 cols</div>
</div>The div might look more complicated, but if you refrain from styling in the tags them selves, you can define different styles in the .css file.
You need the clear:both to start a new line with the divs that float.
I usually run a dedicated "new line" div, without content.. (exception beeing the html-entities version of ' ' (& nbsp ; << without the spaces)).
eg.:
<div style="cls"> </div>Parsing out the values from the PL SQL you do like so:
begin
declare
cursor c_search is
Select ul.meaning,
rqa.submission_date,
rqa.location_num
from
cfa_rqa_doc_submit_dates rqa,
cfa_user_lookups ul
where
rqa.location_num in (Select location_num from cfa_current_locations_mv
where operator_person_id = :P1_PERSON_ID and substr(location_num,1,1) = '8')
and
ul.lookup_type_id='1269'
and
to_char(rqa.submission_date, 'month') = to_char(sysdate, 'month')
and
rqa.submission_date >= (SYSDATE-365)
and ul.lookup_ID= rqa.document_type_id
begin
htp.p('<div style="width:80%;">');
for v_search in c_search loop
htp.p('<div style="float:left;clear:none;">'||v_search.location_num||'</div>');
htp.p('<div style="float:left;clear:none;">'||v_search.submission_date||'</div>');
end loop;
htp.p('</div>');
end;
end;Ps. hope I understood you correctly, also this code is untested.. but I hope it can still help.

Query Report - To display additional column in list selection box.

Hi,
There is query report where i want to display the additional column in list selection.
Below is the system query report, where parameter passed is card code.
When the cardcode - list selection is clicked system displays 2 columns i.e. Customer Code & No. of Records.
Now in the same list selection; is it possible to display the customer name along with cardcode only for reference.
SELECT T0.DocDate, T1.SlpName, T2.Name, T0.DocDueDate, T0.DocNum, (CASE WHEN T0.DocStatus = 'O' THEN 'Open' ELSE 'Closed' END) AS Status, T0.DocTotal FROM OQUT T0 LEFT JOIN OSLP T1 ON T0.SlpCode = T1.SlpCode LEFT JOIN OCPR T2 ON T0.CntctCode = T2.CntctCode WHERE T0.CardCode = N'[%0]' ORDER BY T0.DocNum DESC
Kindly let me know the details.
Thanks & Regards,
Yogesh Jadav

Hi Yogesh Jadav,
The answer is NO. You may only display either code or name but not both.
Thanks,

Content Query display multiple columns

Hello,
I am using a content query web part (in sharepoint 2013) to display a list from another site. The problem is that I don't see enough info from that list because I can display maximum 2 columns.
Is it possible to display more columns from this list with the Content query web part? I would like to display all the columns from this list. Do i need to make a display template or something?
Thanks.

You have to customize the CQWP.
Please check the below link
http://pholpar.wordpress.com/2010/01/21/displaying-results-in-multiple-columns-using-the-content-query-web-part/
Other option is you ca use Dataview webpart to show the list details from one site to other site

Dynamic SQL and Pivot Query in 11G

Hello all,
I am using APEX and 11G I am trying to create a report based on the results of a pivot query. Below is the code to build the query string. The :P4_EPSB_PERIOD_HOLD holds data like (SEP-08') for example.
declare
q varchar2(4000);
begin
q:=q ||' select * FROM';
q:=q ||' ( ';
q:=q ||' select segment2, ';
q:=q ||' accounted_dr, ';
q:=q ||' period_name ';
q:=q ||' from gl_je_lines a, ';
q:=q ||' gl_code_combinations b';
q:=q ||' where b.code_combination_id = a.code_combination_id';
q:=q ||' and segment2 >= :P4_EPSB_OBJECT_FROM';
q:=q ||' and segment2 <= :P4_EPSB_OBJECT_TO';
q:=q ||' and period_name IN :P4_EPSB_PERIOD_HOLD';
q:=q ||' and segment4 >= :P4_EPSB_LOCATION_FROM';
q:=q ||' and segment4 <= :P4_EPSB_LOCATION_TO';
q:=q ||' )';
q:=q ||' PIVOT';
q:=q ||' (';
q:=q ||' sum(accounted_dr)';
q:=q ||' for period_name IN :P4_EPSB_PERIOD_HOLD';
q:=q ||' )';
return q;
end;
I get the missingfailed to parse SQL query:
ORA-00906: missing left parenthesis
If I print the sql statement that the query generates, I get the following code, which, if the varaibles are hard-coded, works fine.
select * FROM ( select segment2, accounted_dr, period_name from gl_je_lines a, gl_code_combinations b where b.code_combination_id = a.code_combination_id and segment2 >= :P4_EPSB_OBJECT_FROM and segment2 <= :P4_EPSB_OBJECT_TO and period_name IN :P4_EPSB_PERIOD_HOLD and segment4 >= :P4_EPSB_LOCATION_FROM and segment4 <= :P4_EPSB_LOCATION_TO ) PIVOT ( sum(accounted_dr) for period_name IN :P4_EPSB_PERIOD_HOLD )
Any advice as to how to tackle this would be most welecome and appreciated.
Thanks

P4_EPSB_PERIOD_HOLDcome with single quotes? like 'SEP-08' or SEP-08

How to display a 1 to many query result in a single row?

Hi,
I want to display a 1 to many relationship in a query in just one row. The current result is that I get more than 1 rows. How can I display it in one column with the additional attribute in a column, without repeating? Thank you.
Select s.student, t.teacher from student_table s, teacher_table t where s.id = t.student_id
Result
Student Teacher
John Doe Larry Woe
John Doe Mary Moe
I would rather get a result like this:
Result
Student Teacher 1 Teacher 2
John Doe Larry Woe Mary Woe
Edited by: Samantha on May 18, 2011 2:48 PM

Hi,
Will all Students have exactly two Teachers?
If not picture your sample with two more Students.
One having 1 Teacher
One having N Teachers
Think about N, what will it be? - How would you create a table with N columns?
If you can't easily answer above, re-consider what you are trying.
That said, it could still be done - even if all Students do not have exactly two Teachers - and is called Pivot a dynamic number of columns.
Examples are in FAQ
SQL and PL/SQL FAQ
Still a bad idea, with or without known number of teachers

Ok, the problem here is that you want a dynamic pivot of data and you also want to use some of the data as the column names.
SQL requires that the columns to be retrieved are known at query parse time, i.e. before any data is fetched, so it's not easily possible to have dynamic column names done in a single query.
The general steps in executing a query are...
1. Submit SQL query (Open Query)
2. SQL Query Parsed
3. SQL Query Executed
4. Row Fetched
5. Repeat step 4 until no more rows
6. Close QuerySo, as you can see no data is fetched until step 4, but, at Step 2, the SQL engine needs to have parsed the query and already know what columns and data types are going to be returned.
An example of how something similar can be achieved is given on this thread:
How to pipeline a function with a dynamic number of columns?
But that may be a little too complex to implement.
What you are really wanting is something at the front end reporting side of things.
Ideally, this is the task of a reporting tool, not of the SQL engine which is retrieving the data.

Count of columns in a query

All,
Could anyone please clarify me on , how we can count the column's which were used in a query.
Ex:    SELECT ENAME, EMPNO, SAL , JOB FROM EMP;
--Here in the above query, I have taken 4 columns(counted manually) . Instead of counting it manually is there any other way.
Thanks

It sounds like you're creating dynamic SQL. Why are you doing that? Dynamic SQL's would seem to indicate you don't know the structure of your own database or that your application design is trying to be generic rather than being designed in proper modularized units (1 unit does 1 task, not multiple generic tasks). 99.999% of the time, people using dynamic SQL indicates that they are misusing the database or haven't designed things properly.
If there's really a valid reason for using dynamic SQL, then of course you can do it properly and use all the features of Oracle to get information about the dynamic SQL, but that means not using something as poor as EXECUTE IMMEDIATE (which is often abused by most people), or trying to use ref cursors within PL/SQL (which are more intended for 3rd party application layers). The power of dynamic SQL is gained from using the DBMS_SQL package... as in the following simplistic example...

Hi,
As you mentioned not possible to assign the dynamic column in the query.
will give you example for generate a dynamic column name in SQL query, using this example you can achieve your requirement.
DECLARE @cols AS NVARCHAR(MAX),
    @query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT distinct ',' + QUOTENAME(C.Name)
                    from [History]
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)')
        ,1,1,'')
set @query = 'SELECT [Date],' + @cols +'
             from
                select [Date], Name, Value

Pivot query probelm

Hi, I am trying to do a pivot report, first I did a simple pivot hard-coding the columns that I was about to use but, it is not convenient so I was asked to do a dynamic report where the columns were selected by a sub-query so I followed the solution from this post
Pivot query using XML option in APEX , but I get this error ORA-00932: inconsistent datatypes: expected - got CLOB, now I know that by default that query is set to return CLOB, but the thing is that when I specify the return value to varchar2 my browser freezes and I cannot go any further than that I need to reboot my browser, I'm using Oracle 11g and APEX 3.2.1 here is my query
SELECT
     xmlserialize(CONTENT DEPARTMENT_XML as varchar2(4000)) XML
FROM
            SELECT
               DEPARTMENT,
               S_GROUP AS "S GROUP",
               S_GROUP
            FROM   MYTABLE where PER = 'BNA' and department not like 'SI%'
   PIVOT XML(
               COUNT(S_GROUP)
               FOR DEPARTMENT
               IN (select distinct department from MYTABLE )          )
ORDER BY 1
Thank you.

Because execuitng the query without the
ROW_NUMBER gives the results in milliseconds
but the row_number takes it 7+ min.I think you mean that executing the query without ROW_NUMBER gives the first rows in milliseconds. However, if you wait until the last row, you may find that it takes several minutes as well. If this is not the case, please post some more details.
And, as BluShadow already said, an additional ordering takes some time, so it will be a little slower, but probably not this much. If you really want to know where time is being spent, then I suggest to take a look at [url http://forums.oracle.com/forums/thread.jspa?threadID=501834&tstart=0]this thread, and start measuring.
