Column Headings on PL/SQL returning SQL Query report- using br

Hi,
I would like to create a report region based upon a function returning a SQL query. As a dem oI have created the following:
create or replace function xxjk_retsql return varchar2
as
begin
return 'select i "column header" from wwv_flow_dual100';
end;I want to be able to insert a line break in the column header so it wraps over two lines. I tried this:
create or replace function xxjk_retsql return varchar2
as
begin
return 'select i "column header" from wwv_flow_dual100';
end;however when the region is rendered, it appears to strip out the HTML tag. I also tried another tag, , as a test and this is stripped out also.
Is there a way to include a break in a column header in this manner?
Thank-you,

There is an option Strip HTML and it is turned on by default. Try changing that to see what happes.

Help with PL/SQL returning SQL query for Report

Hi
I have got a report which I have formatted as PL/SQL function body returning SQL query.
I have the following code
declare
q VARCHAR2(32000); -- query
w VARCHAR2(4000) ; -- where clause
begin
q := 'select min(identified_date) first_identified,' ||
' max(actual_resolution_date) last_closed,' ||
' count("HELPDESK_CALL_ID) total_issues,' ||
' from tbl_helpdesk_calls';
if :P9_call_type != '-1' then
w := 'HELPDESK_CALL_TYPE_ID = :P9_call_type';
end if;
q := q || ' WHERE '|| w;
return q;
end;
When I apply changes I get this error message
Query cannot be parsed within the Builder. If you believe your query is syntactically correct, check the ''generic columns'' checkbox below the region source to proceed without parsing. ORA-00972: identifier is too long
Any Idea where I maybe going wrong?

thanks its compiling now but when I run the page I get this error message in the reports region
failed to parse SQL query:
ORA-00933: SQL command not properly ended
This is my code that I have at the momment.
declare
q VARCHAR2(32000); -- query
w VARCHAR2(4000) ; -- where clause
we VARCHAR2(1) := 'N'; -- identifies if where clause exists
begin
q := 'select min(identified_date) first_identified,' ||
' max(actual_resolution_date) last_closed,' ||
' count(HELPDESK_CALL_ID) total_issues,' ||
' sum(decode(status,''Open'',1,0)) open_issues, ' ||
' sum(decode(status,''On-Hold'',1,0)) onhold_issues,' ||
' sum(decode(status,''Closed'',1,0)) closed_issues,' ||
' sum(decode(status,''Open'',decode
(priority,''High'',1,0),0)) open_high_prior,' ||
' sum(decode(status,''Open'',decode
(priority,''Medium'',1,0),0)) open_medium_prior, '||
' sum(decode(status,''Open'',decode
(priority,''Low'',1,0),0)) open_low_prior '||
' from tbl_helpdesk_calls';
if :P9_call_type != '-1' then
w := 'where HELPDESK_CALL_TYPE_ID = :P9_call_type';
we := 'Y';
end if;
if we = 'Y' then
q := q ||w;
end if;
return q;
end;
I have a select list with a list of reports. what I am trying to do build an sql depending on what the :p9_call_type value is. -1 represents the display value of -All Reports- so if the user selects all reports it should display all results thus removing the where clause. However as my code stands when I user clicks on all reports he get the correct results for all reports. If the user selects anything else they get the error message above.

Export to Excel from Report region (pl/sql returning sql query)

Hello all,
I have encountered an interesting problem. I have an HTMLDB application with a lot of sql reports coded straight inside the report region. In order to better organize my reports, I decided to
1. make all my report regions of type "Pl/Sql function returning SQL query"
2. create a package inside my database schema which houses all reports as pl/sql functions returning VARCHAR2, the string returned being the report query
3. just calling "return package_name.function_name" from inside my report region of type "Pl/sql function returning SQL query".
This technique seemed to work perfectly. The reports were being returned as expected. I was then asked to provide the "Export to Excel" capability to all my reports. This seemed like a piece of cake using HTML DB's "Export to Excel" extension. However, the "export to excel" does not function correctly when my reports are inside a package in the database. HTML DB tries to export but inside the excel spreadsheet, instead of seeing row data, I see:
<pre>failed to parse SQL query:
ORA-00936: missing expression
<!-- select a.username, b.table_name, 'View Row Data' from schema_browser_user_list a, all_tables b where a.user_id = and a.username = b.owner order by b.table_name asc
--!>
</pre>
I am building my query string inside of my package functions by using a combination of literal strings and concatenating them with some parameter values being passed in. It seems that the HTML DB engine which exports the report to excel does not properly understand the concatenation of variables as can be seen by the empty space to the right of the equal sign in the "a.user_id = " clause. Does anybody have any input as to whether this is a known issue or if I am doing something wrong? Thanks a lot for your time.
- Kenny R.

James,
Thanks for the quick reply. I think you mis-understood what I'm doing. All I'm doing is creating packaged functions which return VARCHAR2. The VARCHAR2 that they return is the report query. With this technique, I no longer have to type the query into the HTML DB report region. Instead, I make the report region a "Pl/sql function returning sql query" and make the following call: return package_name.function_name(some_application_items passed in as parameters)
This makes for a much more organized html db app. The problem is that the "export to excel" function does not correctly interpret the VARCHAR2 that my packaged functions are returning. Is this a better explanation? Thanks again for your time.

Is it possible to change the column headings when ever i execute the query

in the runtime i want to change the column headings is that is possible.
Ex: if write a timestampadd(.......) function in the table heading is that change the dates automatically whenever i execute the query?
is this is possible?
Product name 1-2-10 5-6-10
aaaa 5 6
bbfff 6 10

Product name 1-2-10 5-6-10
aaaa 5 6
bbfff 6 10It looks like the dates are values in a column? Put that column in the Columns section of the Pivot Table and Product Name in the Rows section and it should produce what you are looking for.

Display PDF file in the Apex query report using HTML Expression

Hi Folks,
I have PDFs stored in BLOB columns along with FILE_ID column in the database.
I want to display these to the APEX user on the page at runtime.
I have created a SQL Query report page to display FILE_ID column.
I am using HTML Expression property of the FILE_ID column to pull the image from the table using PROC_DISPLAY_DOCUMENT procedure.
I typed folowing code int the HTML Expression text area of the FILE_ID column of the report page :
<img src="#OWNER#.proc_display_document?p_id=#file_id#"/>
I am using following Procedure code:
create or replace procedure "PROC_DISPLAY_DOCUMENT"(p_id number) as
s_mime_type varchar2(48);
n_length number;
s_filename varchar2(400);
lob_image blob;
Begin
select MIME_TYPE,dbms_lob.getlength(blob_content),file_name,blob_content

This code does not work and report does not display PDF image.
Any help to troubleshoot this code will be appreciated.
Thank you in advance.

Query report using LDB MSM

Hi guys,
I'm trying to logical database MSM to report on material master but for some reason the following message appears:
The query specifications cannot be used to generate a list,
i.e. the query will probably not return the list you desire.
If you still want to execute the query, please use the
"Generate" function.
Errors are like this :
Fields from parallel tables within a line
    Line: 01
Field: Post to Inspection Stock
        (MARCV-INSMK, table MARCV)
Field: Item category group from material master
        (MVKE-MTPOS, table MVKE)
Any idea what is the reason why this happens?
Thanks and regards
Stefan

Hey Stefan,
I know this is a long shot, but were you able to figure it out. I am having the same problem as we speak. I tried rearanging the fields according to the heirchy, it now works, but has a really bad output. Hope to hear from you.

Pl/sql - returning sql query

hello everyone...hope someone can help.
Worked a lot to solve this, but I can't find a solution.

like:

report error: ORA-01403: no data found
any suggestions????
also want to edit the column header max character size. now, there can be only *30* characters for column-header. is there a possibilty to raise this?
Thanks for all your suggestions

I get data In sql commands. If I run the statement in sql-commands window, a pop-up opens, where I have to enter any disired value of the item.
It's the item in where condition of the distinct statement
So I get all wisched values.
But in region source, it doesn't work.
I can't get data with an apex item.

Report SUM not working (PL\SQL returning SQL query) using APEX_COLLECTION

I have a simple query
- select ename,sal from emp
(In the Report attribute - SUM property is checked)
I am getting the Report total SUM correctly...
Now I am using the apex_collection object to display the same report.
return select c001,c002 from apex_collections where collection_name = ''EMP'';
c001 - ename
c002 - sal (for this column - I am using Report total - SUM field is checked)
---- Issue is Report total SUM - is always displayed as 0. (actual sum is not coming).
appreciate if I can get some input on this. I have tried a lot but no success..
thanks,
deepak

Hi again
Just checked a similar report test I did a while ago, and my query is:
SELECT c001 MyText, TO_NUMBER(c002) MyNumber
FROM HTMLDB_COLLECTIONS
WHERE COLLECTION_NAME = 'ATD'
So, you should use TO_NUMBER(c002)

Problems with SVG line charts based on PL/SQL returning SQL

Dear all - I wonder if anyone can tell me whether this problem is likely to be fixed at some point?
It relates to the fact that you can't get more than one series on a chart where the SQL is returned from PL/SQL.
It is a huge issue for us when trying to create complex, dynamic charts, which are simple enough in PL/SQL, but end up quite nightmarish in pure SQL.
Although we have implemented Maani SWF (Flash) charts as a workaround, users don't like them as there's no 'save as...' or copy+paste and they seem to print very badly indeed.
Here's part of a post from last May with more detail:
"If I take a really simple table like this:
CREATE TABLE "CHART_TEST"
( "X" DATE NOT NULL ENABLE,
"Y" NUMBER(5,0) NOT NULL ENABLE,
CONSTRAINT "CHART_TEST_PK" PRIMARY KEY ("X") ENABLE
and populate it with:
X Y
2006-01-01T00:00:00 1
2006-02-01T00:00:00 2
2006-03-01T00:00:00 3
2006-04-01T00:00:00 4
2006-05-01T00:00:00 5
2006-06-01T00:00:00 6
2006-07-01T00:00:00 7
2006-08-01T00:00:00 8
2006-09-01T00:00:00 9
2006-10-01T00:00:00 10
I can create a chart with a single series using syntax something like:
begin
return 'select null link, x label, y value
from chart_test';
end;
and this works fine. However, if I add a second series:
begin
return 'select null link, x label, (y + 1) value
from chart_test';
end;
then the whole of the chart region blanks out.
There's an example at:
http://htmldb.oracle.com/pls/otn/f?p=15491:1"
Many thanks,
John.

On some, but not all SVG line charts, I had trouble when some values are ZERO.
Putting a CASE WHEN var = 0 then 0.05 ELSE var END in the select statement
fixed those situations.
I had missing lines when the number of data points in a series exceeded the default number of 15, and I did not set in the series configuration to a number equal to or higher that the number of data points in that series.
And I had one instance, where a couple missing lines reappeared when I exited
the browser and app completely and restarted the app.
All these comments apply to ver 1.6x and 2.0x

Query Report Using Shuttle List

Greetings
I am using Apex Version 4.2
At first, I had created an item P31_JOB_CATEGORY that was a radio button. Upon selecting a value for the radio button, a report was generated. The query is as follows
select a, b, c
from Table A
where A.Job_Category = :P31_JOB_CATEGORYThis gave me the desired report. Now I want to change the radio button to a shuttle list so multiple values can be selected for the job category and generate a the report accordingly. Instead of one value, I can have 2, 3, or all. How would I alter my query to change this? would I have to use an array. I was thinking some type of "Where....In.." clause.
Thanks in advance!

SAP query report - using conditions

Hi
I have a created a query joing 3 tables EKKO,EKBE and custom table with purchase order, article and qty fields.
I want to create a discrepancy report :
1. Display records where EKBE qty (GI qty) and qty (GR qty) in custom table are not equal.
2. Custom table may have some dummy PO numbers( not existing in EKKO). How to pull them in the report?
Since PO numbers are key fields in all tables and joined, any PO number which exists in custom atble but does not exists in
ekko table doesn't appear in the report.
Any input will be highly appreciated.
Thanks
Sanjay

Hi,
Generally the tables for PO are EKKO & EKPO. For the custamized table are referencing PO? If no please give PO reference, ultimately will get upsated in EKKO. Another solution is tim creation stamp field will be there in custamized table. The record creation will be noted here. Pick from this field. Thanking you.

Using collections / Bind variables with a PL/SQL functio returning a query

I have this code, which is supposed to assign collection variables as column names
FOR i in 1 .. Collection_count -1
LOOP
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
SELECT c002 into varholder FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
vQuery:= vQuery || 'SUM(decode(label, ''Aware'', product_'|| i || ', ''Expert'', product_' || i || ', ''Proficient'', product_' || i || ', ''Advanced(Demo)'', product_' || i || ' )) as ';
vQuery:=vQuery || varholder || ', ' ;
END LOOP;
I've tried &P341_M1. , :P341_M1, ':P341_M1', varholder
When I try '&P341_M1' it returns the whole SUM(decode... line as the label
Basically Im having a hard time using bind variables with the PL/SQL returning a query...anybody?

Ok so working through this problem more I have realized that the problem is using the for loop i as an index value
This will get a value:
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;
But this won't
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=i;
I'm in the for loop, and use the i variable in other places within this loop...Is there a reason why I can't compare seq_id to i?
My new code as follows:
FOR i in 1 .. Collection_count -1 --apex_application.g_f01.COUNT - 1
LOOP
varholder:=i;
SELECT c002 into :P341_M1 FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=2;
SELECT c002 into varholder FROM APEX_collections WHERE collection_name = 'MA_SKILLS' AND seq_id=4;
vQuery:= vQuery || 'SUM(decode(label, ''Aware'', product_'|| i || ', ''Expert'', product_' || i || ', ''Proficient'', product_' || i || ', ''Advanced(Demo)'', product_' || i || ' )) as f';
vQuery:=vQuery || :P341_M1 ||i||', ' ;
END LOOP;

Problems with PL/SQL Column Headings

Hello,
I experienced a strange behaviour and perhaps someone can verify it. Perhaps it's a bug, perhaps only some misunderstanding ... 
I created a Region with the Wizard: 
FORM 
TABULAR FORM 
Update Only 
Table EMP (all Attributes) 
Accept rest of Wizard defaults 
Create Region 
OK, everything works fine. 
Now I switched the column Headings to the Type "PL/SQL" and entered in the opening entry field: return('X:EMPNO:ENAME ...... (all Names)...) 
As well everything works fine, the columns are well named. Now I included into the SQL-Statement an additional attribute as a constant. 
select 
"EMPNO", 
"EMPNO" EMPNO_DISPLAY, 
"ENAME", 
"JOB", 
'X', <--------------- 
"MGR", 
"HIREDATE", 
"SAL", 
"COMM", 
"DEPTNO" 
from "#OWNER#"."EMP" 
Now I went back to the Report Attributes to include the new column into my return statement.... but the statement vanished. The little entry field for the PL/SQL-Statement to return the colon delimited header-list is not there and no more available. In the Radiolist for the Headings type it is selected but -as said- not there. (When I go back and erase the additional constand column, the entry-field for the PL/SQL-Statement reappears.) 
Does someone has the same experience or better, a solution ? (APEX 2.2) 
Thanks

Fail to create SQL query report because of ORA-00923

I wonder why if it is getting the error because I could create the report with the following query without problems:

The difference is to add the followings only:

'Open',decode(priority,'2',1,0),

sum(decode(status,
'Open',decode(priority,'4',1,0),

Does anyone have any idea to resolve the issue?

'Open',decode(priority,'2',1,0),
0)) open_prior_2,Sima

Dynamic column headings

I can append p_arg_names=xxx&p_arg_values=yyy to a component's URL to pass parameters to the component. I can change some of the attributes of the component in the same way e.g. for a report:
&p_arg_names=_max_rows&p_arg_values=1
...will return the data 1 row at a time. I am trying to change the column headings in the same manner but when I use:
&p_arg_names=_col_headings&p_arg_values=COL_NAME
... then there is no visible effect. Does anyone have a solution or workaround?

Hi,
What is the purpose you are trying to achieve? There is not such parameter as colheadings.
Thanks,
