Exporting pl/sql functions

Hi,
I know how to register PL/SQL functions in discoverer Admin and also how to export a folder or entire EUL from discoverer Admin and then also how to import them back.
But can someone please tell me how can i export existing pl/sql functions which are registered in Disc Admin to another instance of Disc Admin?
Thanks in advance.

Great!!!
Thanks, I think i missed the Step2.

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

SQL Query (pl/sql function body returning Sql query)

Hi All,
I have created a region of "SQL Query (pl/sql function body returning Sql query)" type and it is working fine , but when I am migrating(export /import) this application from development to systest environment ,
It gives error for this region :
Error ERR-1101 Unable to process function body returning query.
OK
ORA-06550: line 1, column 52: PLS-00306: wrong number or types of arguments in call to 'FU_TRADE_REPORT_QUERY' ORA-06550: line 1, column 45: PL/SQL: Statement ignored
Any pointer ...why this is happening.
Thanks
Dikshit

If your function is a stored function that is called from within APEX (function body not coded into the app itself), have you made sure that the function has been created and compiles ok prior to installing your apex app.
If there are some dependency issues between other PL/SQL units or database objects that are causing your function not to be compiled, you apex install will fail as you are trying to reference an uncompelled bit of pl/sql.
Let me know how you get on

Discoverer - Import PL/SQL Function - Function Not Appears

Hi,
I´m trying to import 15 PL/SQL Funtions inside a custom package into the discoverer administrator, but they do not appear in the list, when trying to do an automatic import.
Also, when I press the Import Button, it takes aproximately one hour to display the list.
I´m using discoverer with Applications.
Do you know what schemes are listed in there ? Because my package is in a CUSTOM Scheme, not the APPS, but it has a Public Synonym.
I need to automatically import these functions in order to not having to do it manually, becasuse it takes to much time.
Also, do you know if there is any way to export the BA and include this functions in there, so I won´t need to register them again in another instance after migration ?
I´m using Discoverer 4.
Thanks in advance.
Nicolas.

Hi Nicolas
When you use the import capability you can import from a named schema so if you have your functions in a schema other than APPS or SYS, which have hundreds if not 1000s of functions, the list should populate quicker.
I'm afraid I don't know of a way to automate the importation of PL/SQL functions. However, if you know the definition of the function rather than importing it why not try creating it manually using the New button? It takes a little getting used to, particularly in getting all of the pointers and arguments correct, but after a while it becomes second nature. This will be quicker than waiting an hour for the list of functions to popuklate.
As for your third question, do you know if there is any way to export the BA and include this functions in there, so I won´t need to register them again in another instance after migration ? the answer is no. PL/SQL functions cannot be exported using Discoverer Administrator and need to be manually imported in the other EUL. You could take screen shots of your existing definitions and manually create them in the new environment using the New button. Once again this will be quicker.
I'm so sorry all of the answers appear negative and please don't shoot the messenger.

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE     MINEX     MAXEX     SOURCE
21     1     10     donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID     V_FNAME     V_CURRENT_EMPLOYER     V_EXPERIENCE_YEARS
2     Vengu     Andale Tech     4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

Passing Multiple Values from a worksheet to PL/SQL function.

Hi All,
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
I will try to explain the scenario:
We have a crosstab report that showing all the customer details, deposit sum of a customer in each date in a date range selected. With the customer details we are showing the Rank of a customer based on the deposit in the latest date selected. Filtering is based on the rank, ie Top50 or Top60 etc.( As I said rank is calculating based on the deposit in the latest date).This is working fine.
Now the new requirement is to : For example, in Top50 report, list all the customers, who were in the Top50 list, in any of the dates selected. We are able to display the daywise rank, but when giving a condition like daywiserank <= 50, the result becomes uncertain. Some blank lines, wrong amounts etc..
As a work around we tried to find out the rank in a PL/SQL function. But the issue there is : we have some multiple value parameters used in the worksheet.
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
Or any other work arounds for the scenario explained?
Reagrds,
Jeneesh

Hi Russ,
Thanks for the response.
Russ Proudman wrote:
1. I thought there was an analytical function similar to rank - or maybe an option of rank - that if there are duplicate records to have them all considered the same rank. So if you had 3 records all the same as rank=2 then a condition saying where rank=2 would return the 3 records. You could check into this.
We are already using DENSE_RANK. But the issue is the output contains incorrect null values nd repeated rows.
We got it solved as I explained in the previous post. But will that AGGREGATION MODE setting ( Which discoverer says - not recommended) have any issue? I mean side effects?
Russ Proudman wrote:
2. Another thought is that you can create a PL/SQL routine - that's called from a SQL function registered in Discoverer - where a table is created that does the first part of your query. Then a worksheet is created to use the data from that table. So, in essence, the table would have your top50 ranked customers. Then you can write any kind of worksheet against that table. However, DBAs are loath to allow tables - that they didn't create! - many times in a PROD environment.
Here also the same problem will occur: as the top 50 will depend upon the parameters. I cannot pass those parameters to PL/SQL Function.And storing the top50 ( itmay be top100 or to 150 also) for all combinations of the parameters is impossible
Russ Proudman wrote:
3. Finally, are you sure you're rank function is correct in that if you're getting blank lines, maybe the 'over' part is not considering all columns needed to determine the rank?
Yes the query we are using is correct. The output QUERY of discoverer gives correct results in Sqlplus.

Show refcursor returned by a PL/SQL function ?

Is it possible to show the results returned by a
PL/SQL function that returns a refcursor ?
In sqlplus it goes like this:
SQL> variable a refcursor;
SQL> execute :a := p_front.get_invoice_list;
PL/SQL procedure successfully completed.
SQL> print a;
INVOICE_ID CLIENT_ID INVOICE_D
101 100 01-APR-06
100 100 06-APR-06
If not, this would be on the top of my wishlist...
By the way: you did a good job on this tool!

Application Report Missing PL/SQL Functional Area

All,
I just wanted to bring to the ApEx developers something I just noticed... I use the Shared Components > Database Object Dependencies report to make sure all is well before moving applications into production.
The Parsing Errors feature of that report is WONDERFUL! But it seems to be overlooking buttons that use a conditional display based on PL/SQL Function Body Returning a Boolean.
Dan

Hi Dan,
I think the place is perfect, but I read once somewhere that "Bug" or "Bug Report" should be in the subject so that's easier to find for the Oracle guys.

Interactive report from PL/SQL function

Hello All,
i have a pl/sql function that dynamically builds up a sql query and returns it as a varchar2.
when i create a new report then i can use this function in the report like
return f_function(param1,param2,v('APP_ID'), v('APP_SESSION'));
and this works fine.
Except i cannot create an interactive report for this function, because it is not allowed !!!!
So how can i use the function in an interactive report ?
Thanks in advance,
Marco

Marco,
Another rather extreme approach would be to go all the way and make your function pipelined (that is not only build but also execute the query) and then select from it in your interactive report.
The disadvantage here would be that any supplementary filtering would act on the result set of the function (not as an addition to the where clause of the original query). But if you can live with that...
The advantage would be that there's less fiddling with column headers.

Iulian

Interactive Report with PL/SQL Function Source

Is it possible to create interactive report with PL/SQL function source returing a query? If not, has anyone done any work to simulate the interactive reporting feature for a normal report using API?

I haven't tried that before but you could:
1. create a collection from your result set returned by a dynamic query,
2. create a view on that collection,
3. use the view in your interactive report.
The usability of this proposal depends from a question how "dynamic" your query is - does it always have the same number of columns or not.

How to call a SQL function from an XSL expression

Hi
In R12, in Payroll Deposit adivce/Check writer, We need to sort the earnings tag <AC_Earnings> in to two different categories as regular and other earnings. In the DB and form level of element defintiion we have a DFF which differentiates between the two kinds of earnings. But the seeded XML that is gerneated by the check writer does not have this field.
The seeded template displays all the earnings in one column. How can we achieve this in the template without modifying the seeded XML.
The one approach i have is to write a function and based on the return value sort the data. For this I need to know :
1) How to call a SQL function from an XSL expression that is allowed in BI template.
If anyone ahs faced similar requirements please share your approach.
Thanks
Srimathi

Thank u..
but i'd seen that link wen i searched in google..
Is it possible without using any 3rd party JARs and all?
and more importantly plz tell me what should be preferred way to call a javascript function?
Do it using addLoadEvent() or Windows.Load etc
OR
Call it thru Xsl? (I donno how to do dis)
Thanks in Advance..

SQL report region source to call a pl/sql function using DB link

Hi - I have a pl/sql function fn_dbtype(id NUMBER) defined in database X. The pl/sql function executes couple DML statements and returns a string (a SELECT query). I am able to call this function using SQL Plus (Connected to Database X) as below and it works fine:
declare
vSQL VARCHAR2(100);
begin
vSQL := fn_dbtype(1);
end;
The DML operations completed fine and vSQL contains the "Select" query now.
In APEX:
I am trying to create a SQL report in APEX using SQL query(PL/SQL function returning a sql statement) option. I am trying to figure out what to put in the region source so that the output of the "Select" query is displayed in the report.
Moreover APEX is hosted in a different database instance. So I would need to call this pl/sql function using a DB Link.
Please let me know what I need to put in the region source to execute the pl/sql function which returns the "Select" query thereby displaying the query output in the report. Thanks.

Problem to create a link with parameters using a PL/SQL function body

Hi everybody,
I need some help to create a link on a SELECT statement.
I have a region report with type "PL/SQL function body return SQL query".
I would like to use a link using HTML tag <a href>.
I know how to do the link, but I don't know to pass a parameters in <a href> statement.
Always I tried it doesn't work well.
My PL/SQL anonimous block is, (just with link) :
DECLARE
q vARCHAR2(4000);
BEGIN
q:='select     "INDICADOR"."NRINDICADOR" as "NRINDICADOR",';
q:=q||'     "INDICADOR"."DSINDICADOR" as "DSINDICADOR",';
q:=q||'''<span style="font-weight:bold;">';
q:=q||'''||TO_CHAR("TOTAL_INDICADOR"."VL_INDICADOR", ''999G999G999G990D00'')||''</span>''';
q:=q||' as "VL_INDICADOR",';
q:=q||'     "TOTAL_INDICADOR"."VL_META" as "VL_META" ';
q:=q||' from     "TOTAL_INDICADOR" "TOTAL_INDICADOR",';
q:=q||'     "INDICADOR" "INDICADOR" ';
q:=q||' where "INDICADOR"."NRINDICADOR"="TOTAL_INDICADOR"."NR_INDICADOR"';
RETURN q;
END;
Thanks for any help,
Alessandra

Your code is in a default value for an item, right?
You need to make sure :P33_YEAR is not null and handle the error in the PL/SQL if it is.
How is P33_YEAR populated? do you pass it in? check to see if it is making it there..

Problem with empty report parameters when passed to PL/SQL function

Hi,
We have come across what appears to be a bug in the JRC. When passing a report parameter to a PL/SQL function as a parameter, empty parameters are changed before being sent to the function. More specifically, an empty string "" ends up as the value "(')" in the PL/SQL function parameter. In our report we print the report parameters on the first page so we know that the parameters are OK before being passed to the database.
The problem exists for version 12.2.203, 12.2.204 and 12.2.205 of the JRC.
We have identified a workaround, but it is not exactly elegant: Before executing the report we modify all empty parameters ("") to " " . In the PL/SQL function, we trim all parameters before using them.
We call the function using a command object with a sql syntax like this example:
select * from table (qa_batch_release.get_qa_br('{?p_report_id}','{?p_reg_set_number}','{?p_cr_number}','{?p_change_id_decode}','{?p_country_id}','{?p_mfg_item_no}','{?p_4_no}','{?p_5_no}','{?p_7_no}'))
The PL/SQL function is a table returning function.
Best regards, Thor

Hi Kishore,
using #COLUMN_VALUE# would probably not make much sense, because normally a report has multiple columns and not just the numeric column which you want to verify if it's negative. But APEX will fire the template condition for each column, because the report template is a column cell template.
What you can do to make it more generic is to use for example
#CHECK_AMOUNT#
in the template and provide a not displayed column in your SQL statement which contains your value which is named CHECK_AMOUNT. For example:
SELECT NAME
, BALANCE
, BALANCE AS CHECK_AMOUNT
FROM XXX;Because this CHECK_AMOUNT column would be a generic name, you can use this template in all your reports as long as you provide this column.
Thope that helps

Passing #COLUMN_VALUE# as parameter to pl/sql function in column template

Hi all,
I want to color negative amounts in red in sql report using column template.
I created a pl/sql function"isNegativeNum" which returns 1 or -1.

         THEN
            RETURN 1;
      else

when others then
   RETURN -1;
end;Below is column template.
Column Template 1
