Dynamic query in updatable report

I have generated a updatable report with the folowing select:
select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"CO_DRUK" druk,
"CO_H2O" h2o,
"CO_O2" o2,
"CO_O2_11" o2_11,
"CO_TEMP" temp
from "#OWNER#"."CORRECTIE"
The table correctie has above the 50 columns (the same columns for different components) so I want to change the query in:
select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"&P50_COMP._DRUK" druk,
"&P50_COMP._H2O" h2o,
"&P50_COMP._O2" o2,
"&P50_COMP._O2_11" o2_11,
"&P50_COMP._TEMP" temp
from "#OWNER#"."CORRECTIE"
The item P50_COMP will be filled with a default value and is a select list with submit.
The problem is when I change the query in the above way, the query cannot be parsed and I cannot applay the changes without parsing the query.
Also not when I use Generic Column Names (parse query at runtime only)
Can somebody help me with this problem.

Fred,
You should switch to a PL/SQL Function Body Returning SQL Statement (Dynamic Query) in order to achieve this. Your Function would look like this:
declare
l_sql varchar2(32767);
begin
l_sql := 'select
"INSTALLATIEID",
"INSTALLATIEID" INSTALLATIEID_DISPLAY,
"' || :P50_COMP || '._DRUK" druk,
"' || :P50_COMP || '._H2O" h2o,
"' || :P50_COMP || '._O2" o2,
"' || :P50_COMP || '._O2_11" o2_11,
"' || :P50_COMP || '._TEMP" temp
from "#OWNER#"."CORRECTIE"';
return l_sql;
end;Thanks,

Dynamic query table for report based on LOV selected

Hi,
Need some suggestion and guidance how to dynamically query table via lov for report .
Scenario:
Table, TABLE_LIST, has tablename (table in DB) and filter (for where clause) column. The TABLENAME_LOVE is derived from table TABLE_LIST.
SELECT TABLENAME D, TABLENAME R FROM TABLE_LIST
In Page 2,a page select list item,P2_TABLENAME to use TABLENAME_LOV
All data in tables in the table_list have identical structure (columns, triggers, primary key, and so on).
I want to have the report region query from the table based on selected LOV.
Example,
Tablename Filter
TB1
CD2 ACTIVE='Y'
When select TB1, the report regin will query based on TB1.
When select CD2, the report regin will query based on CD2 WHERE ACTIVE='Y'
Question:
How can I query based on &P2_TABLENAME. WHERE &P2_FILTER.
Like
select col1, col2 from &P2_TABLENAME WHERE &P2FILTER
Greatly appreciate any suggestion and some guidance.

Hi,
You should always post your Apex version, DB version and other information as suggested in the FAQ.
And the moment you talk report you should state whether it is IR or Classic.
As for your query, have you explored the Report type "SQL Query (PL/SQL function body returning SQL query)" ?
That might be a good fit for what you are trying to achieve.
Regards,

Need to execute Dynamic query for the report

I was wondering if we can have the option of choosing at runtime from the report builder parameter so that if the end-user selects 'Yes' then the report will run one specific query and if he chooses 'No' then another particular query is invoked. What I mean to say that by choosing between Yes and No at runtime one should have the option of returning query results based on the same table but having different columns selected via the SELECT statement
means we have two querires on our report & upon the chosen parameter we should execute only one of them ... wht should i do to apply tht ???

As the previous post noted lexicals are a terrific way to accomplish dynamic queries in Oracle reports.
Another way you could accomplish this would be to use a UNION, whereas the first select in the UNION represents one user option, then second query represents the second option.
For example:
SELECT customer_name name, customer_address address
FROM customer_table
WHERE :p_choice = 'Customer Info'
UNION
SELECT employee_name name, employee_address address
FROM employee_table
WHERE :p_choice = 'Employee Info'If when running the report, the user chooses 'Customer Info' the first query would return results, if the user chose 'Employee Info' then just information from the second query would return information.
So there are different ways to accomplish what you are looking for, you just need to find which is going to work best for you.
Hope this helps!

Dynamic Query for a report

Hi,
I have to generate a report which contains a query with database link. This database link is not hard coded and would be picked up from another report which contans a link to this report. So this database link value for the query could be any. Can anyone guide me hot to write a dynamic select statement so that i could append database link value at run time.
Thanks

Hi,
You can not directly use a PL/SQL query to create an Interactive Report - that is not yet available.
What you could do is create a collection from your query and then use that for the report. Have a look at: [http://download-uk.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32471/advnc.htm#BABGHJFD].
In there, you will see APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY - this allows you to create a collection from a string. You could add a PL/SQL process to your page that runs "On Load: Before Header" that actually creates the collection. Something like:
BEGIN
IF APEX_COLLECTION.COLLECTION_EXISTS('MYCOLLECTIONNAME') THEN
APEX_COLLECTION.DELETE_COLLECTION('MYCOLLECTIONNAME');
END IF;
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY('MYCOLLECTIONNAME','MY SQL QUERY STRING');
END;Your Interactive Report can then be based on:
SELECT SEQ_ID, C001, C002, C003, ...
FROM APEX_COLLECTIONS
WHERE COLLECTION_NAME = 'MYCOLLECTIONNAME'The tricky part is the headings as these would tend to be the SEQ_ID, C001, C002, C003, etc column names from the collection itself.
To get around this, make sure that the report's sql statement includes as many Cnnn columns as you will need for the widest of the reports. Before doing anything else, run the report once to make sure that all these columns are included in the output.
Then, through Shared Components, Application Items, create items that will hold heading names - for example, G_HEADING1, G_HEADING2 etc - one for each possibile column.
Now, update the process to:
BEGIN
IF APEX_COLLECTION.COLLECTION_EXISTS('MYCOLLECTIONNAME') THEN
APEX_COLLECTION.DELETE_COLLECTION('MYCOLLECTIONNAME');
END IF;
IF ..test1.. THEN
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY('MYCOLLECTIONNAME','MY SQL QUERY STRING 1');
:G_HEADING1 := 'ColumnHeading1Value';
:G_HEADING2 := 'ColumnHeading2Value';
:G_HEADING3 := NULL; -- column not used for this query, so set it to null
ELSIF ..test2 .. THEN
APEX_COLLECTION.CREATE_COLLECTION_FROM_QUERY('MYCOLLECTIONNAME','MY SQL QUERY STRING 2');
:G_HEADING1 := 'ColumnHeading1Value';
:G_HEADING2 := 'ColumnHeading2Value';
:G_HEADING3 := 'ColumnHeading3Value';
ELSIF ...etc...
.. etc ...
END IF;
END;Finally, on the report itself, set the column headings to *&G_HEADING1.*, *&G_HEADING2.* etc. Then, on each column, set a Condition of "Value of Item in Expression 1 is NOT NULL" and in Expression 1, enter in the application item for that column - eg, G_HEADING1
I have done all that here: [http://apex.oracle.com/pls/otn/f?p=16338:5] - select either Departments or Employees from the list and the report will change.

Dynamic Query in Report Builder

HI
I have a doubt:
I need to receive a parameter in my report and I need this parameter in the query, that means, I need to create a dynamic query depending on the value that I receive in one of the parameters that has my report.
I tried to use the resource of Searching by Reference Cursor tool, it is a blue circle in the Data Model View of Report Builder.
When I click this tool, I have an initial code, It is:
function QR_1RefCurDS return <RefCurType> is
begin
end;
In PL/SQL I tried to create to test and to play, this code:
Note: If you want to try only to test, it is simple and works:
create or replace package TEST_REFCURTYPE as
type refcurtype is ref cursor;
function TEST_REFCURTYPE (P_DATE_TO nvarchar2) return refcurtype;
end;
create or replace package body TEST_REFCURTYPE as
function TEST_REFCURTYPE (P_DATE_TO nvarchar2)
return refcurtype is
refcur refcurtype;
mysql varchar(1000);
begin
If P_DATE_TO is not null then
mysql := 'select '''|| P_DATE_TO ||''' from dual';
else
mysql := 'select sysdate from dual';
end if;
open refcur for mysql;
return refcur;
end;
end;
The problem is to pass this example of code to the function QR_1RefCurDS, I do not have a place to make reference to the type:
type refcurtype is ref cursor;
I tested the Unit Program in the Report Builder but it did not work, because all the code I try to write and create, for example in the Event BEFORE REPORT, it opens  Funcion( ) …., and I can not make reference to the type refcurtype inside a Function( ).
Would you help me please?
Or there is another way to make a dynamic query in the Report Builder?
Sorry for my English, I am a Brazilian living in Spain.

Hi,
you can use lexical parameters in your queries. Instead of a ":" use in the query before the parameter a "&". Then the parameter stands for a part of the query and not for a value (Bind parameter). In the before report trigger you can set this parameters. They can contain parts of SQL like order or where. Make sure that the default value for this lexical parameters are set to get a valid query.
SELECT ENAME, &p_column as COL2 FROM EMP &p_order
and in the trigger something like
IF :p_which_column = 1 THEN
:p_column := 'SAL'
ELSE

Generating Dynamic Query for Ad-Hoc Reports

Hello,
What is the best way to create a dynamic query to generate ad-hoc reports? I have a couple of ideas but not sure which would work best and be most flexible.
I would like our users to be able to check checkboxes for what data they would like returned in their report. The data would be pulled from a number of tables, 10+, depending on what pieces of data they checked.
Should I write one dynamic query, with a bunch of IF statements in it?
Should I write many individual queries and then join them together in a temp query?
Should I create a temp table on our SQL server which contains the data from all of the tables; then query that? (I am worried about data being out-of-date with this option.)
Which one of these solutions should I go with or is there a better solution that I am not considering?
Thanks for the help.
Josh

Do you mean a Stored Procedure? Would the Stored Procedure then have one query on it with a bunch if IF statements? Maybe a bad example, but something like this?
Yep.
I haven't written a proc for a coupla years (I have DB people to do that for me now, bless 'em), but every DB is different, so the approach will vary depending on what DB you have. It's perhaps time to buy a book or do a google or something.

How to add a row-selector to an existing SQL Query (updatable report)

Hi,
I screwed up an extensive updatable report in Apex 4.2 region by one time indicating the page may be parsed at run time.
After setting this back (to validate query) a lot of the columns setting were gone, and also the row-selector
I actually don't kno how to simply add this row-selector back into place.
Anyone who can point me in the right direction?
Thanks a lot

Anyone who can point me in the right direction?Have you been able to recover all your other configuration and this is the last thing you need to fix? Or are all those other things needing to be fixed as well?
The reason I ask is that you may want to consider just starting from scratch, if you haven't put lots of effort into recovering everything else just yet.
On the other hand, if you just want to add a checkbox back into the SQL statement then you can add this, substituting your column name for empno of course:
APEX_ITEM.CHECKBOX2(1,empno,'CHECKED') "Select"When you do this you'll get a warning that you're changing the interactive report, which you should accept. Then you need to make sure that the column is actually shown in the interactive report by making sure it's in the displayed columns list. And you may also need to change the display type of the column to "Standard Report Column"
Hope that helps.

Dynamic query to produce crosstab/pivot report

Hello,
I've not been able to find any examples similar to my situation but perhaps I'm using the wrong search phrases...
I'm basically trying to create a cross-tab type report based on a dynamic query (since I do not know how many accounts a person has):
select ' SELECT x.name, x.type, ' from dual
union
select ' max(decode(x.account,'''||m.account||''',x.amount,null)) as "'||substr(s.proj||' '||m.account,1,30)||'",'
from db1.manager m, db1.person p, pi.charges c, db1.status s
where m.manager_id = p.id
   and M.ACCOUNT_ID = C.ACCT_ID
   and M.ACCOUNT_STRING = S.project
   and C.JNL = (select max(id) from db1.journ j where j.TYPE ='M')
   and p.username = :username
   and nvl(M.END_DATE, sysdate +1) >= sysdate
group by m.account, s.proj
union
select 'sum(x.amount) grand_total from (select m.account, c.name, c.type, c.amount '
          ||'from db1.manager m, db1.person p, pi.charges c '
          ||'where m.manager_id = p.id '
          ||'and p.username = :P68_PRINC '
          ||'and c.acct_id = m.account_id '
          ||'and c.jnl = (select max(id) '
          ||'from db1.journ j where j.TYPE =''M'')) x '
          ||' group by type, name' from dualThe output from this query for the particular manager I selected is:
SELECT x.name, x.type,
max(decode(x.account,'12012',x.amount,null)) as "Internal 12012",
max(decode(x.account,'17929',x.amount,null)) as "Staged 17929",

max(decode(x.account,'3508',x.amount,null)) as "Stampede 3508",
max(decode(x.account,'9102',x.amount,null)) as "Open Collaborative 9102",
sum(x.amount) grand_total
from (select m.account, c.name, c.type, c.amount
from db1.manager m, db1.person p, pi.charges c
where m.manager_id = p.id

    and c.acct_id = m.account_id
    and c.jnl = (select max(id)
   from db1.journ j where j.TYPE ='M')) x
group by type, nameThis query generates another query that ultimately produces the report below (please pardon the alignment) that I want to see on a report page.

If so, how does that get set up?
Thanks in advance!
~Jake

This solution works in that it generates the proper query. I can copy the query (from debug mode) and paste it in TOAD and it works perfectly. However, in the report page it tells me: "report error:ORA-01403: no data found".
I found this thread: report error: ORA-01403: no data found when SUM columns
I did have a couple other regions on the page (previous attempts) that were hidden so I deleted them completely. Still no luck.
I am also summing up several columns...if that has anything to do with it.
Does anyone have any suggestions?
Thanks again!!!

Interactive report based on dynamic query

Hello
I am using Apex 4.1 and have a requirement to create an interactive report based on a dynamic query. This option is available in Classic report but in Interactive this feature is not there. Tried using collections or just a view (thought of changing the view definition during "On load", but structure of the report is already defined based on the definition of the view at design time).
Is there any way of achieving this?
Appreciate any help!
Thanks

Parameter in form for dynamic query in report

Hello,
I want to send parameters to report for replacing a dynamic query. I don't know how to make it...
1.I want my select statement like
select * from emp
&p_where_clause
2.I want to transfer parameters to report to replace the &p_where_clause.
3.I know I should create a parameter list first, and then use add_parameter built-in to add the parameter, but what I don't know is the correct format of the add_parameter statement.
4.I know the common format is add_parameter(paramlist,'TEXT_PARAMETER',value) , is it the same format if I want to transfer a select statement to report such as "where deptno in ('25','28','30')" for replacing &p_where_clause in report?
Thanks in advance
Joseph

I appreciate your reply, but I am still a little confused...
Actually, I want to pass the where clause to report by different condition. Such as when the user choose the deptment 1, then I can transfer the "where dept_no = '1' and empno > 500", or user choose the deptment 2, I can transfer "where dept_no = '2' and company = '0001'". What I want is to pass different where clause to report according to different condition.
So is it right the statement should be like
DECLARE
vWhere1 varchar2 := 'where dept_no = "1" and empno > 500';
vWhere2 varchar2 := 'where dept_no = "2" and company = "0001"';
BEGIN
IF choose = 1 THEN
ADD_PARAMETER(&P_WHERE_CLAUSE, TEXT_PARAMETER, vWhere1);
ELSIF choose = 2 THEN
ADD_PARAMETER(&P_WHERE_CLAUSE, TEXT_PARAMETER, vWhere2);
END IF;
END;
THANKS AGAIN!!

Multiple Parameter Dynamic Query/Report

I'm very much a newbie to both APEX and SQL. I want to create a page with two regions, one used to hold parameters (LOV Select Lists), and one to reflect a dynamic SQL report including filtering the results using the values of the items in the select lists.
I can do this with one Parameter/LOV select list - but am not clear on how to code for multiple parameters.
Can someone give me an example on how to code the query, to include multiple parameters (P1_Empl, P1_AssetNo, P1_AssetType, etc)? The query with 'null' parameters/filters gives you all records; with any or many parameters acting as filters the query and resulting report would reflect the value of the filters.
In addition, is there a specific type of region that needs to be used for the report region?
Implied is the question - how do you handle the initial page view, so no error messages are seen - I'd like to get all records as a default.
Thanks
Rich

sbkenned,
The referenced sql for that report gives me problems.
[ P3_Department_ID is the LOV of departments ]
[ Null allowed and null return value is -1 ]
<code>
SELECT e.EMPLOYEE_ID,
e.FIRST_NAME,
e.LAST_NAME,
e.HIRE_DATE,
e.SALARY,
e.COMMISSION_PCT,
calc_remuneration(salary, commission_pct) REMUNERATION,
e.DEPARTMENT_ID,
d.DEPARTMENT_NAME
FROM OEHR_EMPLOYEES e,
OEHR_DEPARTMENTS d
WHERE e.DEPARTMENT_ID = d.DEPARTMENT_ID(+) AND
(e.DEPARTMENT_ID = :P3_DEPARTMENT_ID or
(e.DEPARTMENT_ID is null and nvl(:P3_DEPARTMENT_ID,'-1') = '-1'))
</code>
The where clause: I'm guessing it is checking e.deptno = d.deptno
but then what is (+)?
can I use the '(+) and' to add on sections for each select list/parameter?
In the paran part of the where clause, I get the first part and the use of 'or' - but I'm not sure what the last statement is doing.
e.deptno is null AND ?? if there is a null value in P3_Department_ID return -1 otherwise return -1 ??
I'm lost at that point as I clearly don't understand the syntax.
Would you suggest multiple clauses in a where statement in order to add multiple filter values, and how do I handle nulls so those filters are not used/relfected?
I am not using a self submitting LOV select list - I am using a button to refresh the query region manually
I am comfortable with using an interactive report, but that interface is not what I need to present.
As I indicated - I'm weak in the SQL area and need an example on how to code this type of query.
Thanks.

Dynamic query in reports region(multiple condition)

Hi I have this sql query in the report region. And everytime I will run the report and choose to put a value on :P3_REQUESTID and the rest of the variables to null.It doesnt display the report.The same goes to other variables except for :P3_OOTSELECT.
If I choose to put a value on :P3_OOTSELECT and the rest to null, thats the only time that report will be displayed.
What am I missing here?
SELECT req_id,
order_no,
cust_nm,
cust_req_type,
entered_by,
alt_ref,
decode(cnt_rfs,null,null,'Yes')RFS,
rec_id
FROM oot_curr_stats
WHERE (trunc(create_dt,'MONTH') like :P3_OOTSELECT OR
trunc(create_dt) between to_date(:P3_FROMDT,'dd/mm/yyyy') AND to_date(:P3_DATETO,'dd/mm/yyyy'))
AND req_id like '%'||:P3_REQUESTID||'%'
AND sla_tag like :P3_SLATAG
Thanks,
acinorev

Veronica (?),
It doesnt display the report.
What do you mean by that? The report query doesn't execute? Or it does execute and shows "no data found" or something?
If you "choose to put a value on :P3_REQUESTID and the rest of the variables to null" then this part of the predicate won't match any rows (I'll replace the null bind variables with null):
(trunc(create_dt,'MONTH') like null OR
trunc(create_dt) between to_date(null,'dd/mm/yyyy') AND to_date(null,'dd/mm/yyyy'))
Then you AND that with other terms but by then it's too late.
Perhaps I misunderstood.

Dynamic query report problem

I have followed the tutorial in on dynamic query and created a region where the type is SQL Query (PL/SQL function body returning SQL Query)
The source is
declare
q varchar2(4000);
teatid NUMBER := :P305_TARGET_ID;
begin
wwv_flow.debug('teatid = ' || teatid);
q:=' select f.id, ';
q:=q||' f.eat_id ';
q:=q||' from xmlTransactions f ';
q:=q||' where f.eat_id = ' || teatid; -- I've also tried putting :P305_TARGET_ID here
wwv_flow.debug('sql = ' || q);
return q;
end;
I have chosen "Use Generic Column Names...".
When I run the page, I get NO ROWS FOUND. However, when I cut and paste the SQL statement printed out by the debug statement and run it, it returns rows. Both debug statements print correct values.
I'm not sure what the problem is here, but basically, I want to do a query where I substitute a value passed into the page from another page.
In this case the value in P305_TARGET_ID is passed in via a button spawning a popup as in var url = 'f?p=&APP_ID.:305:&APP_SESSION.::::P305_TARGET_ID:' + targetID;
APEX version is 3.0.1.00.08
Thank you.
- JohnW

Hi, JohnW
I don't understand why you use a dynamic query for that.
A "direct" SQL query like this :
select f.id,f.eat_id from xmlTransactions f where f.eat_id=:P305_TARGET_ID;
should work.

Conditional URL ( CASE ) within a Dynamic Query

I need extra eyes or help in RE-FORMATTING the following SELECT STMT. My approach was to formulate the following query to get a functioning URL to the page that displayed the corrections made on that record (if it was corrected)...which I did. So now I'm trying to move the CASE portion into a dynamic query report. I'm having difficulties rewriting the CASE into the dynamic query due to placement of single-quotes. Is there an easy way to do this...or do I still need to find the correct placement of quotes? HELP!

I'm still getting an error which is:

* 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-00905: missing keyword

I still cannot get the insertion of the CASE to compile...I keep getting MISSING EXPRESSION error.

Here is my dynamic query and I want to place the CASE as indicated. The numerous quotes or the Q syntax is really messing up my attempts to get this page working. I have a dynamic query because I am allowing search parameters. And I thought it would be nice to have a LINK to another page that displayed changed column values if a user CORRECTED one of their records. All changes must be verified and accepted by a REVIEWER.

Duplicate records for Dynamic Query in WLS 7

I am getting duplicate records back when I run a dynamic query. If I run the same
query via a finder method, I get the correct results.
Here's the query:
SELECT DISTINCT OBJECT(a) FROM Company AS a, b IN a.userRole WHERE b.userId = ?1
AND a.deptId IN ('1', '2', '3')
Company EJB maps to LU_Company (look up table for company)
Company to UserRole is a one-to-many relationship.
The number of duplicates is equal to the number of records I have for the same company_id
in User_Role table.
The ids for the object I should get back are 1, 2, 3.
Instead I get back 1, 1, 2, 2, 2, 2, 2, 3, 3, 3
In the database, company_id 1 occurs twice in user_role table; company_id 2 occurs
five times.
Any ideas of why the dynamic query has this problem whereas the same query for a
finder method works fine?
Thanks for your help.

Thanks Greg, that worked!

You can supply properties on the query request, perhaps there is a
SQL_SELECT_DISTINCT property:
Properties p = new Properties();
p.setProperty("GROUP_NAME", "fieldgroup");
p.setProperty("INCLUDE_UPDATES", "true");
p.setProperty("SQL_SELECT_DISTINCT", "true");
Collection people = myQuery.find(
"SELECT OBJECT(o) FROM PersonCMPEJB o WHERE o.lastName = 'Smith'", p);

Matt,
<sql-select-distinct> needs to be set in <weblogic-query> element. I amgenerating
a dynamic query from within a local client. So I don't have a finderdefined for
this method. (I don't want to define a finder for this method). How doyou suggest
I can use this? Thanks again for your help.

Hi Mike,
I just filed a bug report for this (CR079471). As a work around, you
can
use the
setSQLSelectDistinct flag so the database will weed out the duplicates.
The only thing to
look out for when using this flag is that Oracle will not allow the use
of 'SELECT DISTINCT'
in conjunction with a 'FOR UPDATE' clause, thus,<sql-select-distinct>True
CANNOT be used if
any Bean in the calling chain has a method with <transaction-isolation>
set to
<isolation-level>TRANSACTION_READ_COMMITTED_FOR_UPDATE. Sorry for theinconvenience.
