Help: APEX - PL/SQL Function

Hello,
i need some help with a SQL statement.
I have the follwing Table "TABF":
ID Number,
B_Number varchar2(10),
G_Type varchar2(10),
Site varchar2(50),
Event varchar2(50),
Date varchar(10),
Dataset varchar2(50),
Mode varchar2(50),
Topic varchar2(10),
Parameter varchar2(10),
Value varchar2(10)The table is filled with records which, like this:
B Number | G-Type |Site       |Event |Date     | Dataset   | Mode    | Topic    | Parameter | Value

If B_Number and Event and Date and Dataset are equal, then add 3 additional columns (Topic2, Paramter2, Value2) at the first aquivalent entry.
Then the row can be delete/ignored. If there will be another record where B_Number,Event, Date are equal to a row above then Topic3, Paramter3 and Value 3 should be added as a new column at the first record where the conditions equals.
And so on.....
The result should look like this for the example above:
B Number | G-Type | Site     |Event |Date     | Dataset   | Mode    | Topic    |Parameter   | Value    | Topic2   | Parameter2 | Value2

Edited by: user11369135 on 09.07.2009 00:50if I understand correctly then you want a simple GROUP BY on B_number, Event, Date and Dataset.
But you want additionaly show 3 columns from one of the rows that was grouped.
This can be done using the little known KEEP syntax.

Help needed with sql function

Hi,
i have a function like below. basically what it does is, check whether first 2 places of a column_name is *'N_'*. if yes then i am replacing column_name which has *'N_' to ''*
CASE WHEN SUBSTR(column_name,1,2) = 'N_' THEN
*':NEW.'||REPLACE(column_name,'N_','')*
i designed this based on the requirement. now i am facing a small issue. i have a column name 'RGN_ID'. so the above function replaces the RGN_ID as RGID as N_ comes in the middle of the column_name the above function accidentally replaces this as well. wherein i need to replace the first 2 position of column_name which starts like 'N_'
can you please suggest any solution for this?
Edited by: user13178284 on Jun 29, 2010 6:11 AM

Thanks!. But i am afraid if this would help.
there may be many column names having 'N_' at whatever position. for eg., TRAN_ID. here N_ comes at 4th and 5th position.
i understand i need to place some kind of check above this function.so that if 'N_' comes anywhere in between the column_name i shouldnt replace it instead i should just replace column_name starting wtih 'N_'.
any idea about this?

Need help with PL/SQL functions

Hi,
Is there a way to compare if a set of elements is present in another set using some function?
Example: Is it possible to find out if all words present in 'BANQUE SAFRA SA' is present in 'BANQUE JACOB SAFRA (SUISSE) SA' using some function in Oracle 9i?
Any suggestion would be appreciated.
Thank you,
Anushree

Boneist,
your solution would giv "false positives":
SQL> with my_tab as (select 'BANQUE JACOB SAFRA (SUISSE) SA' col1 from dual union all
2                  select 'BANQUE SAFRA (SUISSE) SB' col1 from dual union all
3                  select 'BANQUE SAFRA SA' col1 from dual union all
4                  select 'BANQUE SAFRANE SA' col1 from dual)
5 -- end of mimicking your data. USE SQL below!
6 select * from my_tab
7 where col1 like replace('BANQUE SAFRA SA', ' ', '%');
COL1
BANQUE JACOB SAFRA (SUISSE) SA
BANQUE SAFRA SA
BANQUE SAFRANE SA Here is a PL/SQL funcion that does not expect the words in the specific order:
SQL> DECLARE

How to debug PL/SQL function in Apex

Hi,
I have a process in Apex that uses a PL/SQL function. When I compiled it in SQLPlus, it had no errors, yet when running it in Apex, I get an error.
'Encountered unhandled exception in process type PLSQL' in the debug message. What's the best way to handle this? Thanks.

Hi -
Its hard to say without seeing the code of your process, but are you sure you are submitting any required paramaters to your process from the calling apge in Apex?
Have you checked the Session to see what values it holds, and have you turned on Debug in Apex to see the code executing (or at least the call to your process)?
Good luck.

Calling pl/sql function in CKM...pls help

Hi,
I have made a call to PL/SQL function in CKM customization. The code is :
declare
L_PMG_VALUE VARCHAR(3);
begin
L_PMG_VALUE:='PMG';
VALIDATE_PMG_VALUE(L_PMG_VALUE);
end;
When i run it, it throws error which says:
6550 : 65000 : java.sql.SQLException: ORA-06550: line 1, column 64:
PLS-00221: 'VALIDATE_PMG_VALUE' is not a procedure or is undefined
ORA-06550: line 1, column 64:
PL/SQL: Statement ignored
Function is compiled in the database and its working. I have selected the Technology as Oracle and correct Schema Name.
Please help

Hi,
try the following way. i have not tried ....i think it helps you.
In which schema you have created that procedure.
Does the ODI user mantioned in topology have execute permissions on the procedure? if the ODI user have execute previlage on the procedure then in CKM customisation call the procedure like <schema>.<procedure>.
Please let me know any issues.
Thanks,

Help w/MaxDB Function; also: how does the "Debug SQL" function work?

Hi there forum folks,
In my former life, I was a Basis guy, but I haven't had the pleasure of working directly with SAP applications in a few months. My current project is to attempt to use MaxDB in a real estate environment. We're tracking home listings so that we can build statistical reports... such as "what agents are in the Top 100 in postal code X?"
Anyway, as part of this project, I have attempted to construct my very first MaxDB database function. Unfortunately, it doesn't give me the answers I'm hoping to see. Here's the function:
CREATE FUNCTION COUNT_LISTINGS (AGENTID CHAR(10)) RETURNS FIXED(6,1) AS
VAR COLISTINGAGENTID CHAR(10);
      LISTINGAGENTID   CHAR(10);
      MLSNUMBER        CHAR(7);
      UNITS            FIXED(6,1);
SET UNITS = 0;
DECLARE FUNCTIONRESULT CURSOR FOR
    SELECT MLSNUMBER,
           LISTINGAGENTID,
           COLISTINGAGENTID FROM FREDDIE.GLAR_SOLDS
     WHERE LISTINGAGENTID = :agentid OR COLISTINGAGENTID = :agentid;
IF $COUNT IS NULL THEN
    BEGIN
      CLOSE FUNCTIONRESULT;
      RETURN UNITS;
    END
ELSE
    SET $RC = 0;
WHILE $RC = 0 DO BEGIN
    FETCH FUNCTIONRESULT INTO :mlsnumber, :listingagentid, :colistingagentid;
    IF ( LISTINGAGENTID   = AGENTID AND COLISTINGAGENTID IS NULL ) OR
       ( COLISTINGAGENTID = AGENTID AND LISTINGAGENTID   IS NULL ) THEN
      SET UNITS = UNITS + 1
    ELSE
      SET UNITS = UNITS + 0.5;
END;
CLOSE FUNCTIONRESULT;
RETURN UNITS;
I've tried to follow the official MaxDB documentation. My first deviation from that standard was the use of the "$COUNT" variable (instead of the "$RC" variable) immediately after the DECLARE/SELECT statement above. When I tried to use $RC, for either a successful or unsuccessful query, $RC was always set to a non-zero value.
I believe I'm past that, but now my issue is down around that FETCH statement. The UNITS variable doesn't end up with the value I expect. I know that it can be terribly confusing to try to analyze someone else's logic, but here's a brief narrative that describes what I'm trying to do...
The GLAR_SOLDS table holds one line for each home sold. It's keyed by the MLSnumber. Each record also stores up to four agents who've been involved in the transaction: the listing agent, the co-listing agent, the selling agent, and the co-selling agent. The database function I've written above pertains to the listing side only. If I can get this to work, a separate function will process the selling side. If no co-listing agent is involved in a given sell, that agent should get credit for 1 unit sold. If he/she has help from a co-listing agent, the agent should only get credit for 1/2 unit sold.
Also, does anyone know how the "Debug SQL" functionality is supposed to work within Database Studio? When I right-mouse click on my function, and follow the path thru "Debug As...", after entering the connection & function arguments, I'm presented with an empty screen. If you could point me to some documentation somewhere, I'd gratefully read it.
I'm using MaxDB 7.7.06.09 on Windows XP (WIN32) with MaxDB Database Studio 7.7.06.09 (build 009-123-202-944).
Thanks everyone for your help & advice.
~Fred

Fred,
please either provide the full SQL statements for your example or stick with mine.
I'm not going to build it up myself a second time to suit yours now.
> But now, my issue is how do I store the resultant data in its own table?
So where is the problem?
INSERT INTO <target table> (field 1, field 2, ...) (<your query>) UDPATE DUPLICATES-
With my tables this looks like this:
create table sell_result (list_agent varchar(20) primary key, SUM_CREDIT fixed (10,2))
insert
into sell_result (list_agent,sum_credit)
    ( select list_agent, sum (credit) as SUM_CREDIT
      from ( select sh.object_id,lag.name as list_agent, 1 as credit
             from soldhomes sh join agents lag on lag.id = sh.list_agent_id
            union all
             select sh.object_id, lag.name as list_coagent, 0.5 as credit
             from soldhomes sh join agents lag on lag.id = sh.list_coagent_id
      group by list_agent
update duplicates
Check what we have now
sqlcli db770=> select * from sell_result
| LIST_AGENT           | SUM_CREDIT        |
| -------------------- | ----------------- |
| Lars                 |              4.50 |
| Lisa                 |              3.00 |
| Mona                 |              2.50 |
| Paul                 |              2.50 |
4 rows selected (600 usec)
Now add some sales data...
Insert into soldhomes values (11, 1, 2, NULL, NULL)
Insert into soldhomes values (12, 2, NULL, NULL, NULL)
Insert into soldhomes values (13, 2, NULL, NULL, NULL)
Re-run the INSERT command and you're done:
sqlcli db770=> select * from sell_result
| LIST_AGENT           | SUM_CREDIT        |
| -------------------- | ----------------- |
| Lars                 |              5.50 |
| Lisa                 |              3.00 |
| Mona                 |              5.00 |
| Paul                 |              2.50 |
4 rows selected (390 usec)
Neat, isn't it?

SQL function help

Hi, I am trying to write a sql query to replace the string starting with '<' with NULL. Right now I am using CASE statement to replace with NULLs. Is there any function to replace with NULLs for all the strings starting with '<%'.
Example:
CASE When field_name LIKE '<%' then NULL else field_name
(before) After
<NA> NULL
<UK> NULL
I want to replace the above sql suery with a single sql function without using CASE statements.
I tried to use REPLACE function, but it replaces only single character. I want to replace the whole string
Thanks in advance.

Hi,
Adam Martin posted a good solution. I hope that it is clear to you that you have to replace the string '<NA>' with your column(s).
I.e.:
SELECT REGEXP_REPLACE (a.col1, '^<.?+', '') AS col1
     , REGEXP_REPLACE (a.col2, '^<.?+', '') AS col2
FROM table1 a;
{code}
You can use also the DECODE and SUBSTR functions to have the same result:
The code below will get the first character with SUBSTR function and the DECODE function will return NULL if the value of the first character is "<" otherwise the value of the column.
{code:sql}
SELECT DECODE(SUBSTR(a.col1,1,1),'<', NULL, a.col1) AS col1
     , DECODE(SUBSTR(a.col2,1,1),'<', NULL, a.col2) AS col2
FROM table1 a;
{code}
but using REGEXP_REPLACE is easier to write.

LOOP in PL/SQL Function Body Help Needed

I have a PL/SQL function that I'm trying to run and use a LOOP but I'm having some problems. I know the loop works since it output's two commas for me, which is how many records the query used for the LOOP returns, but I can't seem to find the right syntax to reference the column.
DECLARE
str VARCHAR2(2000) := "";
BEGIN
IF :P21_GLOBAL_ID IS NOT NULL THEN
FOR q IN (
SELECT
ID,
DRAW_DATE,
ENTERED_BY
FROM
SAMPLE_T
WHERE
ID = :P21_GLOBAL_ID
ORDER BY
DRAW_DATE
LOOP
str := str || q.ID || ',' ;
END LOOP;
END IF;
RETURN STR
END;

I just sent you the credentials.
Interestingly, I have this same code for the source of a textarea on the page and the source for a report. I then modified the PL/SQL code as follows:
DECLARE
     varSelect VARCHAR2(32767) := ''; --hold query SELECT definition
     varFrom VARCHAR2(32767) := ''; --hold query FROM clause definition
     varWhere VARCHAR2(32767) := ''; --hold query WHERE clause definition
     varOrderBy VARCHAR2(32767) := ''; --hold query ORDER BY clause definition
     varQuery VARCHAR2(32767) := ''; --hold query definition
BEGIN
     IF TRIM(LOWER(TO_NUMBER(:P21_GLOBAL_TEMPLATE_ID))) IS NOT NULL THEN
          varSelect := 'SELECT SUBJECT_ID';
          varSelect := varSelect || ', SUBJECT_ID AS PHI';
          varSelect := varSelect || ', SUBJECT_ID AS ENTER_DATA';
          varSelect := varSelect || ', SUBJECT_ID AS LOGISTICA';
for varTempQuery IN (
SELECT
stc.question_name as field_name,
sti.read_security,
sti.write_security,
nvl(sti.validation_type,decode(stc.validation_rules,'None','TEXT_FIELD')) as validation_type,
sti.html_caption,
nvl(upper(sti.html_display_type),'TEXTFIELD') as html_display_type,
sti.html_table_row,
sti.html_table_column
FROM

rix.study_subject_Template_items sti,
rix.questions stc
WHERE
TRIM(LOWER(TO_NUMBER(sst.ss_template_Id))) = TRIM(LOWER(TO_NUMBER(:P21_GLOBAL_TEMPLATE_ID)))
AND TRIM(LOWER(TO_NUMBER(sst.ss_Template_id))) = TRIM(LOWER(TO_NUMBER(sti.ss_Template_id)))
AND TRIM(LOWER(TO_NUMBER(sti.phi_qid))) = TRIM(LOWER(TO_NUMBER(stc.qid)))
AND TRIM(LOWER(TO_CHAR(sti.template_item_Status))) <> TRIM(LOWER(TO_CHAR('RETIRED')))
ORDER BY
sti.html_Table_row,
sti.html_table_column
LOOP
varSelect := varSelect || ', ' || varTempQuery.field_name;
END LOOP;
          varFrom := 'FROM     RIX.SUBJECTS';
          varWhere := 'WHERE STUDY_ID = ' || TRIM(LOWER(TO_NUMBER(:P21_STUDY_ID )));
          varOrderBy := 'ORDER BY';
          varOrderBy := varOrderBy || ' subject_label ';
varQuery := varSelect || ' ' || varFrom || ' ' || varWhere || ' ' || varOrderBy;
     ELSE
varQuery := 'SELECT SUBJECT_ID FROM SUBJECTS WHERE study_id = :P21_STUDY_ID;';
     END IF;
RETURN varQuery;
END;
When I run the page now, the textarea has the SQL statement generated from the first IF block, but the report using the statement from the ELSE block. I thought it maybe was a timing issue, but both blocks reference other fields on the page, so it doesn't seem to be a timing issue. Shouldn't be a condition issue either with the IF block as the textarea and report use the same source, but are evaluating differently.
Very odd (to me at least).

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.
create or replace function isNegativeNum(p_column_value varchar2) return number
as
l_dummy number;
begin
      l_dummy := to_number(p_column_value,'999G999G990D00PR');
      IF l_dummy < 0
         THEN
            RETURN 1;
      else
            return -1;
      END IF;
exception
when others then
   RETURN -1;
end;Below is column template.
Column Template 1
<td class="t3dataalt" #ALIGNMENT#><p color=red>#COLUMN_VALUE#</p></td>Column Template 1 Condition
isNegativeNum('#COLUMN_VALUE#') = -1The issue is #COLUMN_VALUE# value is not being passed to the function, Insert statement in function reveals p_column_value as a string "#COLUMN_VALUE#". When I try without quotes like isNegativeNum(#COLUMN_VALUE#) = -1, I get below error.
ORA-06550: line 1, column 48: PLS-00103: Encountered the symbol "#" when expecting one of the following: ( ) - + case mod new not null others select table avg count current exists max min prior sql stddev sum variance execute multiset the both leading trailing forall merge year month DAY_ hour minute second timezone_hour timezone_minute timezone_region timezone_abbr time timestamp interval date
     Error      ERR-1025 Error processing PLSQL expression. isNegativeNum(#COLUMN_VALUE#) = 1
Any help is appreciated.

PL/SQL function body returning SQL - report error:ORA-01403: no data found

Hi,
I am working on Application Express 4.0.2.00.06, and 11G database.
I have a problem with classic report area of type - PL/SQL function body returning SQL query. Query works if I define region area as - Use Generic Column Names (parse query at runtime only), and does not when I define it - Use Query-Specific Column Names and Validate Query.
I am getting error:
report error:ORA-01403: no data found
This is my query that is returned from function, and displayed with htp.p, and it works ok and returns data in SQL Developer and SQL Workshop (in Apex).
<code>
/* select 1 from dual */ SELECT SIFPRO, NAZIV, VODITELJ, DATPZA,SUM(DECODE(TJEDAN,'2010/46',BRDJEL,null)) as "2010/46" ,SUM(DECODE(TJEDAN,'2010/49',BRDJEL,null)) as "2010/49" ,SUM(DECODE(TJEDAN,'2010/50',BRDJEL,null)) as "2010/50" ,SUM(DECODE(TJEDAN,'2010/51',BRDJEL,null)) as "2010/51" ,SUM(DECODE(TJEDAN,'2010/52',BRDJEL,null)) as "2010/52" ,SUM(DECODE(TJEDAN,'2011/01',BRDJEL,null)) as "2011/01" ,SUM(DECODE(TJEDAN,'2011/02',BRDJEL,null)) as "2011/02" ,SUM(DECODE(TJEDAN,'2011/03',BRDJEL,null)) as "2011/03" ,SUM(DECODE(TJEDAN,'2011/04',BRDJEL,null)) as "2011/04" ,SUM(DECODE(TJEDAN,'2011/05',BRDJEL,null)) as "2011/05" ,SUM(DECODE(TJEDAN,'2011/06',BRDJEL,null)) as "2011/06" ,SUM(DECODE(TJEDAN,'2011/07',BRDJEL,null)) as "2011/07" ,SUM(DECODE(TJEDAN,'2011/08',BRDJEL,null)) as "2011/08" ,SUM(DECODE(TJEDAN,'2011/09',BRDJEL,null)) as "2011/09" ,SUM(DECODE(TJEDAN,'2011/10',BRDJEL,null)) as "2011/10" FROM (SELECT * FROM PMV_PLAN_TVRTKA) GROUP BY SIFPRO, NAZIV, VODITELJ, DATPZA ORDER BY SIFPRO, NAZIV, VODITELJ, DATPZA
</code>
As you can see, I even tried with workaround that I found on the previous post on the forum, and that is to put /* select 1 from dual */ to start query.
Any help would be appriciated.

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
The PL/SQL function :
CREATE OR REPLACE FUNCTION contact_details(ACT_CODE1 IN NUMBER) RETURN VARCHAR2 IS
Project_codes varchar2(10);
CURSOR contact_cur IS
SELECT ACT_CODE,PROJECT_ID
FROM ACTASQ.ASQ_CONTACT where ACT_CODE = ACT_CODE1;
currec contact_cur%rowtype;
NAME: contact_details
PURPOSE:
REVISIONS:
Ver Date Author Description
1.0 6/25/2009 1. Created this function.
BEGIN
FOR currec in contact_cur LOOP
dbms_output.put_line(currec.PROJECT_ID || '|');
Project_codes := currec.PROJECT_ID|| '|' ||Project_codes;
END LOOP;
RETURN Project_codes;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL;
WHEN OTHERS THEN
-- Consider logging the error and then re-raise
RAISE;
END contact_details;
/

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>

SQL Query ( PL/SQL function body returning query ) page

Hello Friends,
I have a page with type SQL Query ( PL/SQL function body returning query ).
I have written a pl/sql block that returns a sql query - select statment.
Some times i am getting no data found error - does it got to do with the variable that stores the query .
=======================
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
Error ERR-1101 Unable to process function body returning query.
OK
=====================
When the query is returned with records where exactly the records are stored is it in the variable declared in pl/sql block or with the Oracle Apex implicit cursor.
Here's the pl/sql block ..
The query is generated while the user is navigating through pages ..
====================
declare
l_return_stmt varchar2(32767);
l_select varchar2(32000);
l_from varchar2(32000);
l_where varchar2(32000);
l_order_by varchar2(32000);
l_stmt_recordcount varchar2(32000);
l_recordcount number ;
begin
l_select := 'select '||:P10_VARLIST1||:P10_VARLIST2||:P10_VARLIST3
||:P10_VARLIST4||:P10_VARLIST5;
l_from := ' from '||:P10_RELATION;
if length(:P10_WHERE) > 0 then
l_where := ' where '||:P10_WHERE;
else
l_where := '';
end if;
if length(:P10_ORDER_BY) > 0 then
l_order_by := ' order by '||:P10_ORDER_BY;
else
l_order_by := '';
end if;
l_return_stmt := l_select||l_from||l_where||l_order_by;
:P10_STMT := l_return_stmt;
return l_return_stmt;
end;
=============================
Appreciate your help in this regard.
thanks/kumar

It looks like the query string you are trying to pass back exceeds the 32K limit for a varchar. Where this is happening is kind of difficult to tell as it could be any number of points, and also depends on what you are passing into the process via page items.
I would first try to establish what combination of page items causes this error to occur. Then, starting from the bottom and working your way backwards, I would start 'switching off' some of the items you use to build your query until it breaks again, thus establishing which part is leading to the error.
Also, I'm not sure what :P10_STMT is doing (are you maybe using this for visiblity of the query created)?

Hello,
This application process "vrl_popup" is to get the values from PL/ SQL function. For popup window - confirm(). Also declared the LV_list as Application Item.
Which is coded in the region part of the button. After pressing this button popup window should come with the list.

In apex I created following Application process by name = vrl_popup,
declare
lv_List varchar2(2000) := '';
begin
begin
lv_List := select vrl_type_process_pkg.get_regd_reg_lste() from dual;
