PL/SQL FUNCTION VAR VALUE

Hello everybody.
a Short question , I need help with this, I have a report based in a SQL Query (PL/SQL function body returning SQL Query) and I need to see the query returned.
My question ¿How I can see the content of the query that I construct?.
Any help wellcome.
Thanks & regards everybody.

You may compute your query in an item:

Pass a value from a PL/SQL function to a javascript (html header) ? ?

Hey Guys,
Have a question regarding how to pass a value from a PL/SQL function to a javascript in the HTML Header.
I have created a PL/SQL function in my database, which does looping.
The reason for this is: On my apex page when the user selects a code, it should display(or highlight buttons) the different project id's present for that particular code.
example= code 1
has project id's = 5, 6, 7
code 2
has project id's = 7,8
Thank you for your Help or Suggestions

Jesh:
I have made the following modifications to your app to get it to work as I thing you need it to.
1) Changed the source for the HTML Buttons Region(note use of id vs name for the Buttons)
<script>
function hilitebtn(val) {
//gray buttons
$x('graduate').style.backgroundColor='gray'
$x('distance').style.backgroundColor='gray'
$x('career').style.backgroundColor='gray'
$x('photo').style.backgroundColor='gray'
//AJAX call to get project-ids
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=GETPROJECTS',0);
get.addParam('x01',val)
gReturn = get.get();
var arr=gReturn.split(':'); //dump into array
get = null;
for (i=0;i<arr.length;i++) {
// alert('val=' + arr);
if ( arr[i]==5)
$x('graduate').style.backgroundColor='red';
if ( arr[i]==6)
$x('distance').style.backgroundColor='red';
if ( arr[i]==7)
$x('career').style.backgroundColor='red';
if ( arr[i]==8)
$x('photo').style.backgroundColor='red';
</script>
<table cellpadding='0' cellspacing='0' border='0'>
<tr><td>
<input type='button' id='graduate' value='Graduate'>
</td>
<td>
<input type='button' id='distance' value='Distance'>
</td>
<td>
<input type='button' id='career' value='Career/Tech'>
</td>
<td>
<input type='button' id='photo' value='Photos'>
</td>
</tr></table>
2) Defined the application process GETPROJECTS as DECLARE
IDS varchar2(1000);
l_act_code varchar2(100) :=4;
begin
IDS:='';
l_act_code := wwv_flow.g_x01;
for x in(
SELECT ACT_CODE,PROJECT_ID
FROM ASQ_CONTACT
where ACT_CODE = l_act_code)
LOOP
IDS := IDS || X.PROJECT_ID|| ':' ;
END LOOP;
HTP.PRN(IDS);
END;
3) Changed the 'onchange' event-handler on p1_act_code to be 'onchange=hilitebtn(this.value)'
4) Added the JS to the HTML Page Footer <script>
hilitebtn($v('P1_ACT_CODE'));
</SCRIPT>

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.

PL/SQL function body returning SQL query - ORA-06502: PL/SQL: numeric or value error

I'm attempting to dynamically generate a rather large SQL query via the "PL/SQL function body returning SQL query" report region option. The SQL query generated will possibly be over 32K. When I execute my page, I sometimes receive the "ORA-06502: PL/SQL: numeric or value error" which points to a larger than 32K query that was generated. I've seen other posts in the forum related to this dynamic SQL size limitation issue, but they are older (pre-2010) and point to the 32K limit of the DNS (EXECUTE IMMEDIATE) and DBMS_SQL. I found this post (dynamic sql enhancements in 11g) which discusses 11g no longer having the 32K size limitation for generating dynamic SQL. Our environment is on 11gR2 and using ApEx 4.2.1. I do not know which dynamic SQL method -- DNS or DBMS_SQL -- ApEx 4.2.1 is using. Can someone clarify for me which dynamic SQL method ApEx uses to implement the "PL/SQL function body returning SQL query" option?
As a test, I created a page on apex.oracle.com with a report region with the following source:
declare
l_stub varchar2(25) := 'select * from sys.dual ';
l_sql clob := l_stub || 'union all ';
br     number(3) := 33;
begin
while length ( l_sql ) < 34000 loop
    l_sql := l_sql || l_stub || 'union all ';
end loop;
l_sql := l_sql || l_stub;
for i in 1 .. ceil ( length ( l_sql ) / br ) loop
    dbms_output.put_line ( dbms_lob.substr ( l_sql, br, ( ( i - 1 ) * br ) + 1 ) );
end loop;
return l_sql;
end;
The dbms_output section is there to be able to run this code in SQL*Plus and confirm the size of the SQL is indeed larger than 32K. When running this in SQL*Plus, the procedure is successful and produces a proper SQL statement which can be executed. When I put this into the report region on apex.oracle.com, I get the ORA-06502 error.
I can certainly implement a work-around for my issue by creating a 'Before Header' process on the page which populates an ApEx collection with the data I am returning and then the report can simply select from the collection, but according to documentation, the above 32K limitation should be resolved in 11g. Thoughts?
Shane.

What setting do you use in your report properties - especially in Type and in Region Source?
If you have Type="SQL Query", then you should have a SELECT statement in the Region Source. Something like: SELECT .... FROM ... WHERE
According to the ERR-1101 error message, you have probably set Type to "SQL Query (PL/SQL function body returning SQL query)". In this situation APEX expects you to write a body of a PL/SQL function, that will generate the text of a SQL query that APEX should run. So it can be something like:
declare
mycond varchar2(4000);
begin
if :P1_REPORT_SEARCH is not null THEN
mycond:='WHERE LAST_NAME like :P1_REPORT_SEARCH ||''%''';
end if;
return 'select EMPLOYEE_ID, FIRST_NAME, LAST_NAME from EMPLOYEES ' ||mycond;
end;
And for escaping - are you interested in escaping the LIKE wildcards, or the quotes?
For escaping the wildcards in LIKE function so that when the user enters % you will find a record with % and not all functions, look into the SQL Reference:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14200/conditions007.htm
(You would than need to change the code of your function accordingly).
If you are interested in escaping the quotes, try to avoid concatenating the values entered by the user into the SQL. If you can, use bind variables instead - as I have in my example above. If you start concatenating the values into the text of SQL, you are open to SQLInjection - user can enter anything, even things that will break your SQL. If you really need to allow users to choose the operator, I would probably give them a separate combo for operators and a textfield for values, than you could check if the operator is one of the allowed ones and create the condition accordingly - and than still use bind variable for inserting the filtering value into the query.

Using return value of a pl/sql function in the "where" coarse in a

Hi,
I have a question,
if I have a pl/sql function that returns a boolean value, how can I use
it directly in a select statement?
I can easily do this if the function returns a number value , e.g.
select * from my_table where my_package.function('abc') = 1;
But I can't figure out how to do this if the function return a boolean.
Any idea other than creating another function?
Please reply to me directly as I'm not in the email list. Thanks.

BOOLEAN is not a SQL datatype - you can only reference Boolean values in PL/SQL.

Yes I am returning a value from PL/SQL function.
Please see the code segments below,
FUNCTION "TD_INSERT" (a TDINIT_TYPE, stops TDDETAIL_TABLE )
RETURN VARCHAR2
AS
td_no Number;
td_id Number;
stop TDDETAILFULL_TYPE;
length number;
BEGIN
insert into TD_INIT values( ----passing all the values here --------- );
select max(tdno) into td_no from TD_INIT ;
length := stops.count;
for i in 1.. length loop
stop := stops(i);
insert into TD_DETAIL_FULL values(
td_no, ------- );
end loop;

How to call pl/sql function from element values

EBS 11.5.10.2
XMLP 5.6.3
Hello,
I noticed that the output of the rdf-to-data template conversion process makes use of an undocumented feature of data templates, and I would like to get input from experts as to which situations this feature is usable.
The closest thing I can find in the documentation is a sample in the user guide. There is a "General Ledger Journals Data Template Example" that has a <dataStructure> section that contains <element> nodes which are NOT children of a <group> node. I can't find any explanation of this in the user guide.
I've noticed from converted templates that in these un-grouped elements you can make calls to PL/SQL functions in the "value" attribute, like this:
<dataStructure>
<group name="G_LINES" source="Q_MAIN">
    <element name="Line_Num"           value="Line_Num"/>
</group>
<element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
</dataStructure>Has anyone had any success being able to call PL/SQL functions from grouped elements? Whenever I try, it doesn't seem to work.
When I try something like this:
<dataStructure>
<group name="G_LINES" source="Q_MAIN">
    <element name="Line_Num"           value="Line_Num"/>
    <element name="some_calculation"   value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
    <element name="some_calculation_b" value="XX_CUSTOMPROCS.SOME_FUNCTION_B(:Line_Num)"/>
</group>
<element name="C_CALCULATED_VALUE" dataType="number" value="XX_CUSTOMPROCS.SOME_FUNCTION"/>
</dataStructure>The <SOME_CALCULATION/> and <SOME_CALCULATION_B/> nodes come out empty in the output data xml file, but <C_CALCULATED_VALUE> would have a value as desired.

ah - perfect. That makes sense. Thank you for the response!
But what about when we need to pass parameters to those functions whos values are the results of aggregate element values?
This happens a lot in the converted data templates, where pl/sql package functions are meant to replace formula columns from the original Oracle Report. Take this example from the conversion of ARXAGMW.rdf (Aging Report, 7 Buckets):
(note the function call in the value of "Set_Percent_Inv_Inv" is using aggregate results from subgroups)
<group name="G_INV_INV" dataType="varchar2" source="Q_Invoice">
    <element name="Total_Inv_Inv_Amt" function="sum" dataType="number" value="G_Invoice.C_Amt_Due_Rem_Inv"/>
    <element name="Total_Inv_Inv_B0" function="sum" dataType="number" value="G_Invoice.C_Inv_B0"/>
    <element name="Total_Inv_Inv_B1" function="sum" dataType="number" value="G_Invoice.C_Inv_B1"/>
    <element name="Total_Inv_Inv_B2" function="sum" dataType="number" value="G_Invoice.C_Inv_B2"/>
    <element name="Total_Inv_Inv_B3" function="sum" dataType="number" value="G_Invoice.C_Inv_B3"/>
    <element name="Total_Inv_Inv_B4" function="sum" dataType="number" value="G_Invoice.C_Inv_B4"/>
    <element name="Total_Inv_Inv_B5" function="sum" dataType="number" value="G_Invoice.C_Inv_B5"/>
    <element name="Total_Inv_Inv_B6" function="sum" dataType="number" value="G_Invoice.C_Inv_B6"/>
    <element name="Set_Percent_Inv_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.set_percent_inv_invformula(:Total_Inv_Inv_Amt, :Total_Inv_Inv_B0, :Total_Inv_Inv_B1, :Total_Inv_Inv_B2, :Total_Inv_Inv_B3, :Total_Inv_Inv_B4, :Total_Inv_Inv_B5, :Total_Inv_Inv_B6)"/>
    <element name="Sum_Percent_B0_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B0_Inv_p"/>
    <element name="Sum_Percent_B1_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B1_Inv_p"/>
    <element name="Sum_Percent_B2_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B2_Inv_p"/>

    <element name="Sum_Percent_B6_Inv" dataType="number" value="XX_CUSTOMPROCS.XXC_ARXAGMW.Sum_Percent_B6_Inv_p"/>
    <group name="G_Cust_Inv" dataType="varchar2" source="Q_Invoice">
      <group name="G_Site_Inv" dataType="varchar2" source="Q_Invoice">
        <group name="G_1" dataType="varchar2" source="Q_Invoice">
          <group name="G_Invoice" dataType="varchar2" source="Q_Invoice">
            <element name="C_Amt_Due_Rem_Inv" dataType="number" value="C_Amt_Due_Rem_Inv"/>
            <element name="C_Inv_B0" dataType="number" value="C_Inv_B0"/>
            <element name="C_Inv_B1" dataType="number" value="C_Inv_B1"/>
            <element name="C_Inv_B2" dataType="number" value="C_Inv_B2"/>
            <element name="C_Inv_B3" dataType="number" value="C_Inv_B3"/>
            <element name="C_Inv_B4" dataType="number" value="C_Inv_B4"/>
            <element name="C_Inv_B5" dataType="number" value="C_Inv_B5"/>
            <element name="C_Inv_B6" dataType="number" value="C_Inv_B6"/>
          </group>
        </group>
      </group>
    </group>
</group>
...All of these groups and sub-groups are based on one single query, so I am not sure how I would move the function call into the query without changing the results of the function.
In the example above, elements Sum_Percent_B0_Inv through Sum_Percent_B6_Inv grab the results of the calculation done in set_percent_inv_invformula. Here is the essence of that function:
sum_percent_b0_inv := ROUND ((total_inv_inv_b0 / total_inv_inv_amt) * 100, 2);
sum_percent_b1_inv := ROUND ((total_inv_inv_b1 / total_inv_inv_amt) * 100, 2);
sum_percent_b2_inv := ROUND ((total_inv_inv_b2 / total_inv_inv_amt) * 100, 2);
sum_percent_b3_inv := ROUND ((total_inv_inv_b3 / total_inv_inv_amt) * 100, 2);
sum_percent_b4_inv := ROUND ((total_inv_inv_b4 / total_inv_inv_amt) * 100, 2);
sum_percent_b5_inv := ROUND ((total_inv_inv_b5 / total_inv_inv_amt) * 100, 2);
sum_percent_b6_inv := ROUND ((total_inv_inv_b6 / total_inv_inv_amt) * 100, 2);The only solution I can think of is to have separate queries, one for each subgroup, that do the "sum" in sql; but that seems terribly inefficient.

Item value not showing up in PL/SQL function on another item.

Basically, I am trying to update a database field based on the vaule of 2 other fields, but the item value dow not seem to get stored. No errors, it just shows up as a null value in the database. Here is the code inside the default area as a FL/SQL Function.
declare

begin
select concat(mname,id) into P14_TNUM from T1,T2 where mid=:P14_TID;
return P14_TNUM;
exception when others then
return null;
end;
Note:
id is in T1
mname and mid is in T2
:P14_TID is the item which points to the pk in table T1

Pass a list of number values to a pl/sql function

I would like to pass a list of number values to a pl/sql function where the list will be used in an IN clause. Ideally I would like to do the following:
CREATE OR REPLACE FUNCTION ( dept_list in varchar2) is
begin
select ... where dept in (dept_list) ;
usage: process_list ( '7730,7735,7740,7745') ;
I can not find an example of doing this in pl/sql function but it seems feasible.
Is there a way to do this?

usage: process_list ( '7730,7735,7740,7745') ;The first thing is you need an appropriate data type to store a list of numbers. A single character value that looks to you like a list of numbers, is not in fact a list of numbers but a single character value.
This example uses the built in data type odcinumberlist in a procedure, you can do the same in function
Re: Passing an array to an Oracle stored procedure
If you have an old version of the database you may need to create your own type with the same definition of odcinumberlist.

PL/SQL Function call error while reading or assigning returned value

Hi,
I am getting the following error while tryih to read the value of the PL/SQL Function. I am calling a function in one of my PL/SQL Packages passing mutliple IN parametes and the function returns some value back. Now on BPEL side when I try to read the return value I am getting an error:
*<summary>*
empty variable/expression result.
xpath variable/expression expression "/ns3:OutputParameters/ns3:TEST_FUNCTION" is empty at line 124, when attempting reading/copying it.
Please make sure the variable/expression result "/ns3:OutputParameters/ns3:TEST_FUNCTION" is not empty.
*</summary>*
Even though in the console when I check the Invoke Output Parameter it does shows me a valid value being retuned by a Function but when I am trying to Assgn this value to some variable using Assign Activity I get the above error.
Even though all goes fine but looks like I am not able to read or assign the value returned from the Function.
So just wondering if this even works as to me I have a very simple example and that seems not to work. Function is called successfully and is returning the value as I can see it in the BPEL console but when tryin to read or assign that value to some other variable I get the above error.
Any ideas?
Thanks

This issue has come up a lot. The problem is with a mismatch between the version of JDeveloper and SOA. You'll encounter namespace issues if you use 10.1.3.1 in combination with 10.1.3.3 (or 10.1.3.4). You MUST synchronize both JDev and SOA to 10.1.3.3 or 10.1.3.4 (mixing 10.1.3.3 and 10.1.3.4 is OK). We changed when going to 10.1.3.3 by adding elementFormDefault="qualified" to the generated XSD. We used the default "unqualified" in 10.1.3.1. So you'll encounter namespace issues unless you're using 10.1.3.3 or higher JDev AND SOA. The fact that I see <*db:*...> tells me that you're using 10.1.3.1 JDeveloper. The correct solution is to upgrade your components.

PL/SQL function/Expression in a default value

Hi,
I want to generate a sequence number using oracle sequence and populate a field when user hits create button. I tried using PL/SQL expression in the default value of a field. What is the exact syntax for this. I tried this
:P18_PROJECT_NUMBER := MNT_PROJECTS_NUMBER_S.NEXTVAL;
Did not work.
select MNT_PROJECTS_NUMBER_S.NEXTVAL into :P18_PROJECT_NUMBER
from dual;
Did not work. Can anyone help me with this ?
Thanks

Naresh - You should never say something "did not work" without saying what happened. It is useless otherwise.

My requirement is to use single value check box and pass the flag value to the pl/sql function.
The function need to interpret the flag and execute accordingly.
In this case checkbox name is P1_DELETE and it returns Delete, if checked.
Anonymous block with in the process looks as follows:
declare
l_result VARCHAR2(1024);
begin
l_result := test_function(:P1_DELETE);
end;

Hi Visu,
checkboxes in APEX are handled as arrays, namely APEX_APPLICATION_GLOBAL.VC_ARR2. To pass and process the checked values of checkboxes in a pl/sql function or procedure you could use the following way, assuming you have a checkbox named P1_DELETE with a single return value of "Delete"
DECLARE
    l_checkbox_values apex_application_global.vc_arr2;
BEGIN
    l_checkbox := :P1_DELETE;
    -- calling function test_function processing the value
    test_function(NVL(l_checkbox(1), 'SOME_OTHER_VALUE'));
END;If the checkbox is not checked then the array at position 1 is null and you have to process that as you like.
If your checkbox would be a group than the array would be colon separated such as 1:2:3:4 etc. and you would have to loop the array like:
    FOR idx IN 1..l_checkbox.COUNT LOOP
        test_function(l_checkbox(idx));
    END LOOP;Hope that helps.
