Using bind variables in Shared Component Reports not working

I've created a report query as a shared component in my APEX application. I'm calling the report on a page via a button. The query behind the report has bind variables for period and entity fields which are both defined on Page 0. I can run the query and return values just fine, but when you run the report from the page via the button, I get no values back. Does anyone know a trick to getting this to work? I've been working in APEX for about a month and I don't have much developer experience so any help is appreciated.
Regards,
-Steve

Rohit,
Thanks for your response. We are using APEX version 4.2.1.00.08. I do have Session State enabled and have put the required page items in the list. Here is my report query (highlighted lines contain the bind variables):
SELECT TAX_DIVISION.DIVISION_CODE Division,
TAX_ENTITY.ENTITY_CODE Entity_Code,
DECODE(TAX_ADJUSTMENT.CATEGORY_DESC,'Net Income/(Loss)',1,'Permanent Adjustment',2,'Temporary Adjustment',3,4) Category_Desc,
TAX_ADJUSTMENT.CLASSIFICATION Classification,
TAX_ADJUSTMENT.ADJUSTMENT_CODE Adjustment_Code,
SUM(NVL(NVL(TAX_ENTITY_ADJUSTMENT.OVERRIDE_AMT,TAX_ENTITY_ADJUSTMENT.ADJUSTMENT_AMT),0)) Tax_Amount
FROM TAX_DIVISION,
TAX_ENTITY,
TAX_ENTITY_ADJUSTMENT,
TAX_ADJUSTMENT,
TAX_PERIOD
WHERE TAX_DIVISION.DIVISION_ID = TAX_ENTITY.DIVISION_ID
AND TAX_ENTITY.ENTITY_ID = TAX_ENTITY_ADJUSTMENT.ENTITY_ID
AND TAX_ENTITY_ADJUSTMENT.ADJUSTMENT_ID = TAX_ADJUSTMENT.ADJUSTMENT_ID
AND TAX_ENTITY_ADJUSTMENT.PERIOD_ID = :P0_PERIOD_ID
AND TAX_ENTITY_ADJUSTMENT.YEAR_ID = :P0_YEAR_ID
AND TAX_ENTITY.DIVISION_ID = :P0_DIVISION_ID
AND TAX_ADJUSTMENT.ADJUSTMENT_CODE = 'IBIT'
GROUP BY TAX_DIVISION.DIVISION_CODE ,
TAX_ENTITY.ENTITY_CODE ,
DECODE(TAX_ADJUSTMENT.CATEGORY_DESC,'Net Income/(Loss)',1,'Permanent Adjustment',2,'Temporary Adjustment',3,4),
TAX_ADJUSTMENT.CLASSIFICATION ,
TAX_ADJUSTMENT.ADJUSTMENT_CODE
HAVING SUM(NVL(NVL(TAX_ENTITY_ADJUSTMENT.OVERRIDE_AMT,TAX_ENTITY_ADJUSTMENT.ADJUSTMENT_AMT),0)) !=0
ORDER BY DIVISION_CODE, DECODE(TAX_ADJUSTMENT.CATEGORY_DESC,'Net Income/(Loss)',1,'Permanent Adjustment',2,'Temporary Adjustment',3,4), CLASSIFICATION, ENTITY_CODE, ADJUSTMENT_CODE
The query returns data when I set the bind variables and test in the report queries screen. When I assign the report query URL to the button in the application and run from there, I get no results.

Bind Variables and Shared Component Report Query

I have a query in a region report which I have replicated to a shared component report query.
Both queries reference page items as bind variables in the where clause.
The report region on screen shows the correct results but the report query shows "no data". This is the case when running "Test Query" and "Download XML data" from the shared component report query definition. If I hardcode the variable names I get rows returned, If I use bind variables - and specify the values for these variables I get no data. THe XML file contains the tags for each bind variable I have specified but has no data between the tags. I have Ticked the box to include application and session state but it appears that the bind variables are not being used.
When I use my report query in the application (URL tied to a button) I get the same problem, the binds are not being passed to the report query.
Can someone please clarify if this is a bug or not? And if not, how can I get it to work.
I am using Apex 4.0.2
Thanks
Kathryn

Hi
To confirm, yes I selected the bind variables. I used these in the report layout, but the xml file has them as empty i.e.
<P0_START_DATE><P0_START_DATE/> with nothing in between.
IN the Test Query section, if I put real values in the boxes for the bind variables, I get no data found. If I hardcode the values into the query, I get the data.
I've repeated the create report query many times and have created a report layout in RTF. I can use the layout with my region - in the print attributes and the layout works with the query but I need to create a PDF using 2 queries - ROWSET1 and ROWSET2. I can generate the XML but the values in the rows are all empty. When I use the layout with a report query instead of the region, I get no data even though I have used the same sql and have selected the bind variables. I was using variables from page items on page zero but have also tried using page items on the current page, the result is the same.
I need to use a report query and a report layout as I need data from 2 queries in the PDF.
I looked at your demo - what happens if you add a second sql query to the report query - is there any chance I can look at the back end (developer access?)
Thanks for your input

Using bind variables in user defined reports

How do I go about using a bind variable in a user defined report?
Here's a trivial example in SQL*Plus:
var ublocksize number
begin
select value into :ublocksize
from v$parameter
where name = 'db_block_size';
end;
select :ublocksize from dual;
This code does not work in raptor.
The error displayed is:
Missing IN or OUT parameter at index:: 1
Vendor code 17041
any ideas?

You also have a second issue of supporting the following syntax in SQL scripts:
var ublocksize number
begin
select value into :ublocksize
from v$parameter
where name = 'db_block_size';
end;
We are itterating to support all SQL plus commands

Setting a bind variable in a Shared Component Report Query

I have defined a Shared Component Report Query in APEX using a bind variable similar to below
Select name, id , ....
from asset
where id = :id
I have also created a Report Region that displays a table where one of the columns contains a value I would like to be a link column that can launch the Report Query and pass its value to the bind parameter :id in the report query. This in turn would generate a pdf report for the details associated with that column. I am having problems setting the :id bind parameter. How do I do this?
Can anyone help?
Thanks

The bind values are set from session state. So if try something like this:
Select name, id , ....
from asset
where id = :P1_ID
With P1_ID being a page item, for which you set the session state / value before generating the PDF file. So assuming you already have a page with a report and a page item, and that page item is already used in your report, then you could just create a button to download the PDF, make sure the button is a submit button, and create a branch pointing to the report query URL (or in 3.1 use the create button wizard, to do this declaratively.)

Marc

Report Using Bind Variables

Hey Everyone,
I'm having a bit of trouble creating a report. I need the FROM part of the code to use bind variables. I have come up with this peice of code below but im getting the following error:
failed to parse SQL query:
ORA-06550: line 1, column 8:

Hey Roel and Daylocks,
After getting frustrated for a while i deleted the page and started again. I put in the exact same code and it worked just how i wanted in the first place :S
The only thing i did different is when i was creating the report region the first time around i used a normal SQL query, For Example:
select sysdate from dual;
Then i modified it to
DECLARE
x VARCHAR2 (4000);
BEGIN
x := x || 'select ';*
x := x || 'from ';
x := x || :p14_schema;
x := x || '.ddl_log@';
x := x || :p14_db_name;
x := x || '_DBAAPEX.TNTEWW.COM';
RETURN (x);
END;
Whereas on the second attempt i used the peice of code in question straight away. Its been a bit of a frustrating morning because i used a similar peice of code for a different application, nevermind tho :)
Thanks for your replys, much appreciated.

How to use SYSDATE as a default value of a bind variable in a query report?

Hi,
I want to use SYSDATE as default value for a bind variable in Query based report.
I don't see any way to do it, someone helps?
Thanks a lot.
Paulo.

You can aslo use #sysdate directly.
Hi,
The way I'm doing in my report is, I have a database function (f_ret_sysdate) with the following code
create function f_ret_sysdate return varchar2
begin
return to_char(sysdate,'mm/dd/yyyy');
end;
Now, in the 'Customization Form Display Options' section of the report I'm calling this function as #f_ret_sysdate in the default value field of corresponding bind variable to display SYSDATE with the format.
Hope this helps!...

Do not use bind variable notations for p_session_id argument...

Hi there,
... in apex_custom_auth.login the Apex doc says. Does anyone know why not?
LOGIN Procedure
Also referred to as the "Login API," this procedure performs authentication and session registration.
p_session_id Current Oracle Application Express session ID.
Note: Do not use bind variable notations for p_session_id argument.Thanks
Luis

I tend to avoid assigning values to bind variables like that - but it may be due to the nature of much of my code residing in PL/SQL packages.
And due to the strange encounters I have had with this, like your linked discussions, I've tended towards using apex_util instead.

Csv no data found when using bind variables

Hi,
I have created a report, that uses 2 date variables to limit the query and rows display as they should. But clicking the csv link opens csv having one row stating 'No data found...'. If I set static values in place of variables, I get the right result. How could I use bind variables and get the right answer in csv (without coding my own function)?
Kaja

I am having the same problem.
The export link opens a new session without submitting the current page. The page item values are therefor not saved to cache before the export is undertaken.
Any report using page item bind variables in the where clause will not export correctly as the bind values are either null or those of the previous page submit.
Any ideas on how to get round this??

Please help me.
Thanks.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

How to use bind variables in desc flexfields in OA pages?

Use case: In EBS 11i we have a DFF on po_vendors and one of the segment has a table validated value set that is referencing a forms variable i.e :VENDORS.VENDOR_ID. Now after upgrading to R12 this won't work as the vendor pages moved to OA framework. Is there any way to reference the vendor_id column in OA framework?

Can we just link to an oracle form using a url still as we can with reports? I've built a report that requires the user to select from a dynamic list as well, and I know how to do this through forms, but can I simply call the form from a webpage?

Possible for Oracle to consider constraints when using bind variable?

Consider the following table with a check constraint listing the possible values of the column
create table TEST_TABLE(
my_column varchar2(10));
insert into TEST_TABLE select 'VALUE1' from dba_objects;
alter table TEST_TABLE
add constraint TEST_TABLE_CHK1
check (my_column in ('VALUE1', 'VALUE2'));
begin dbms_stats.gather_table_stats(ownname=>user,tabname=>'TEST_TABLE');END;Let's see the number of logical I/O's needed for the following SQL statements.
(The value was obtained by the delta ofselect m.value from v$mystat m, v$statname n
where name='session logical reads' and m.statistic#=n.statistic#)
If string lateral is used:
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE1';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE2';
end;
Consistent Gets: 21
declare
   n number;
begin
select count(*) into n from test_table where my_column='VALUE3';
end;
Consistent Gets: 0Oracle can eliminate the table if it knows the queried value can't satisfy the constraint. Good.
(Actually, the execution plan for the last query included the 'FILTER' operation.)
However, if bind variable is used:
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE1';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21
declare
   n number;
   x varchar2(10);
begin
x := 'VALUE3';
select count(*) into n from test_table where my_column=x;
end;
Consistent Gets: 21Oracle can't eliminate the table using the constraint. I can understand that because bind variables are used, Oracle can't directly eliminate the table when generating the execution plan. However, is it possible to eliminate the table, or at least employ some shortcut in runtime? If not, will this be a performance loss compared with using values laterals when check constraint exists?
(And is it possible to use autotrace on PL/SQL block in sqlplus?)
Oracle:
     10.2.0.4 SE
     11.2.0.2 SE
OS:
     RHEL5

However, is it possible to eliminate the table, or at least employ some shortcut in runtime? I can't see how to do this. Oracle has a sqltext that has an embedded bind variable in it. And for this sqltext it has an execution plan in the shared pool that will be used irrespective of the actual bound values at runtime.
Maybe in 11G, with adaptive cursor sharing / plan bind awareness, Oracle might be smart enough to introduce a second execution plan for the VALUE3 case.
If not, will this be a performance loss compared with using values laterals when check constraint exists?Only if you submit the dumb query and search for records with VALUE3... Normally your application code would not hold/generate these queries.
Will it?
For columns whose values are bound by a CHECK constraint, one might even consider to never use bind variables, since very likely you will have few versions of queries that use these columns.
Not?
