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)?

Function Body Returning Query - Questioning my Approach

Application Express 3.2.0.00.27
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
I have some concerns that I am not using this in the optimal manner.
Essentially I have all my queries in a package body and I call each report as follows:
declare
v_query varchar2(4000);
begin
v_query := apex.report_name(p1=>   :page_item_1,
                                              p2=>   :application_item2);
return 'select * from ('|| v_query||' )';
end;I then generate the string in the report_name procedure
and concatenate the string.
This results in a valid sql string being returned to the database , however if I pass a different value
then I will get a different sql string.
I would rather be able to use bind variables using this approach if at all possible.
So is this the correct approach is there a better approach?

Current project makes extensive use of packages containing Function Body Returning Query report sources to dynamically build queries from SQL modules. However, the queries generated by any function are all used within one page. This enables page item bind variable references to be fixed within the SQL:
function emp (p_commission in number) return varchar2
is
q_emp_qry varchar2(4000) := q'{select * from emp where 1 = 1 }';
k_has_comm constant varchar2(2000) := q'{and comm >= to_number(:p2_sales_comm)}';
begin
if p_commission is not null
then
    q_emp_qry := q_emp_qry || k_has_comm;
end if;
return q_emp_qry;
end emp;

Unable to process function body returning query

I have a table called ACCESS. The table has two columns, PERSON_ID NUMBER (holds employee reference) and SQL_QUERY VARCHAR2(4000) (holds query 'SELECT COL1, COL2, COL3 FROM APEX_TABLE;' )
I am in the process of generating SQL Report. In the Create SQL Report (Page > SQL Report >Create SQL Report),
I want to dynamically fetch the SQL_QUERY from the ACCESS table something like the below one.
DECLARE
strSql VARCHAR2(4000);
BEGIN
SELECT SQL_QUERY INTO strSql FROM ACCESS WHERE PERSON_ID=100;
RETURN strSql;
END;
I get the error Unable to process function body returning query when I try to run the page.
However if I hardcode the query in the PL/SQL block, it works for example:
DECLARE
strSql VARCHAR2(4000);
BEGIN
strSql := 'SELECT COL1, COL2, COL3 FROM APEX_TABLE';
RETURN strSql;
END;
How to resolve this?

Hi Denes,
In your demo application you are using the below query (function returning sql). Is it possible to store this query as VARCHAR2 in a database table and query the table to return the QUERY ('SELECT deptno....')? Can you explain me with an example?
DECLARE
q VARCHAR2 (1000);
BEGIN
q := q || 'SELECT deptno, DECODE(deptno, ';
q := q || '10, ''<img src="#IMAGE_PREFIX#bullet1.gif" >'', ';
q := q || '20, ''<img src="#IMAGE_PREFIX#bullet2.gif" >'', ';
q := q || '30, ''<img src="#IMAGE_PREFIX#bullet3.gif" >'', ';
q := q || '40, ''<img src="#IMAGE_PREFIX#bullet4.gif" >'') ';
q := q || 'image, dname FROM DEPT ';
q :=
q
|| 'WHERE CASE WHEN TO_NUMBER (:p1_dept) != -1 THEN deptno '
|| 'ELSE 1 END = CASE WHEN TO_NUMBER (:p1_dept) != -1 '
|| 'THEN TO_NUMBER (:p1_dept) ELSE 1 END';
RETURN q;
END;
Thanks

SQL query (pl/sql function body returning query) performance issue

I create my report in building my sql instruction with ( SQL Query pl/sql function body returning sql query );
My report take more than 20 seconds however if i did a cut and paste with the sql code in TOAD the same sql take 1 second.
To try to discover the source of the problem; i take the sql generated by the function and i create another report ( sql query ) this new report take 2 seconds.
My query is very big 25,000 characters with database link.
What is the difference between SQL-quey and sql-query(pl/sql function body returning sql query)
Thanks
Marc

Marc,
Firstly...don't compare the timings from Toad, since often Toad only fetches the first few records for you (i.e. it pages them).
Secondly....the database link could be a factor here, but without seeing your query it's too hard to say.
Can you post the query somewhere (on a webserver say)?

Report pl/sql function body returning query bind variable

I really like using report with a function returning sql. I have been using something like this
declare
q varchar2(10000);
begin
q := 'select col1
from mytable
.... add a dynamic where clause ....
return q;
end;
But I thought it would be nice to store the query in a bind variable so that I could show the where clause. I tried to create an item P123_Q and do the following:
declare
q varchar2(10000);
begin
q := 'select col1
from mytable
.... add a dynamic where clause ....
:P123_Q := q;
return q;
end;
But the parser treats :P123_Q as if it is a bind variable within flow 4000. I found a workaround but I'm wondering if there is a better way.
My workaround is to set a preference in the query and then use a computation that sets P123_Q to the value of the preference:
declare
q varchar2(10000);
begin
q := 'select col1
from mytable
.... add a dynamic where clause l_q := l_q || ....
HTMLDB_UTIL.SET_PREFERENCE(
p_preference => 'Q',
p_value => q,
p_user => :APP_USER);;
return q;
end;
Any thoughts on another way?
thanks,
Anton

EncounteringERR-1101 Unable to process function body returning query

hi,
I am new to APEX and finding some difficulties while developing an application. My application chooses a value from a dropdown, and depending on the value chosen, adds some columns in the report.
The code is somewhat like below:
DECLARE
--variable declaration for col headers for ports
l_p_name ports_ver.port_name%TYPE;
l_id ports_ver.port_id%TYPE;
type pstr is varray(25) of varchar2(100);
nm pstr;
hdr varchar2(1000);
chd varchar2(100);
msg varchar2(6000);
msg1 varchar2(6000);
h varchar2(60);
begin
l_p_name := :PR_VALUE; ----the dropdown value
msg := 'select 1 "Edit" , p.ID "ID",p.TEST_MANAGER "Manager",p.AREA_NAME "Area", p.COMPONENT "Component", v.port_name "Port",';
select version
bulk collect into nm
from ports_ver
where port_name=l_p_name;
for i in nm.first..nm.last
loop
select get_col_head(l_p_name,nm(i)) into hdr from dual;
chd := 'Tstng Pltfrm '||nm(i);
msg := msg||' hdr "'|| chd ||'", ';
--msg1 := msg || 'null, ';
end loop;
msg1:= msg || 'p.imp_blk_bug "Blocking Bugs" , p.NUM_SCENARIOS "No of Scenarios" ,p.PASS "Pass", p.FAIL "Fail" ,p.COMPLETE "Complete" ,p.COMMENTS "Comment" ,v.version "VERSION" from PORT_FFT p,ports_fft_sts s ,ports_ver v
where v.port_name = l_p_name ;';
return msg1;
end;
can you point me some hints?

Hi, and welcome!
Firstly, you don't need to end the SQL statement with a semi-colon as you are returning a SQL query rather than PL/SQL code. So, change:
where v.port_name = l_p_name ;';to:
where v.port_name = l_p_name';Your SQL statement itself uses three tables, yet your WHERE clause only references two - is this intentional?

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

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.

Error in report when executing pl/sql function body returning sql query.

Hi,
I have used the pl/sql function body returning sql query for creating a report. I have created a datepicker(
P10_TASK_DATE) which can be submitted.The code is as below
DECLARE
v_sql varchar2(3000);
BEGIN
if :P10_TASK_DATE is not null THEN
v_sql:='select
* from tasks';
return v_sql;
else
v_sql:='select * from discovery';
return v_sql;
END IF;
END;if the date field is empty "select * from discovery" is executed and report is getting generated. But when we give a
date using date picker the page is submitted and i get "report error: ORA-01403: no data found" even
though the "tasks" table has data in it. Plz help
Thanks,
TJ

hi
Please try this
1. Create 2 region
1st region source=
select * from tasks'
go to the tab -> condition =
item NOT NULL
EXpression1 =:P10_TASK_DATE
this will run whenever the item have any date
2. open your 2 nd region source code= select * from discovery
put the condition
item is NULL
EXpression1 =:P10_TASK_DATE
thanks

Region source (PL/SQL function body returning SQL query)

Hi, guys.
Here is what i try to do:
Create a region of type SQL Query (PL/SQL function body returning SQL query). In the source area i tried to put this:
DECLARE
v_new VARCHAR2(10);
v_SQL varchar2(32000);
BEGIN
v_new := :P102_HDN_NEW;
-- htp.p(v_new);
IF v_new = 'N-Set' THEN
v_SQL := 'select ' ||
ELSIF v_new = 'Y-Set' THEN
v_SQL := 'select ' ||
END IF;
RETURN v_SQL;
END;
And here is the reply from APEX:
1 error has occurred
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. The query can not be parsed, the cursor is not yet open or a function returning a SQL query returned without a value.
Now.
1. Variable is set with the right value.
2. Each statement (separately) returns SQL that works with no problems
3. Problem occures if i try to put IF statement around the SQL creation.
4. If i select "Use Generic Column Names (parse query at runtime only)" instead of "Use Query-Specific Column Names and Validate Query" then the script returns SQL properly, however report's column names are set to Col1, Col2,Col3 ......

Multiple Select List looping thru PL/SQL function body returning SQL query

Hi,
I have a Multiple Select List. I want to loop through the values from the Select List and process them in a PL/SQL function body returning a SQL query. Currently, my code only returns the SQL SELECT results of one item in the select list. How do I change my code to make it return the results of all of the items in the select list? (I tested it and it is definitely picking up all the values in the select list).

Thank you,

Laura,
First, I would be careful of introducing SQL Injection possibilities. Any time I see
'Select ... ' || :P123_FOO || ' ... '
I worry about sql injection. In your case you are converting :P50_SELECTED_INSTRUMENTS into selected_items and then selected_items into s. So when I see
'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''' || s ||'%'' '||
I think, "I could use sql Injection and hack this."
So, I would do some validation on :P50_SELECTED_INSTRUMENTS or some other method to avoid this.
I'm not certain I understand your query. Do you really intend to allow the user to select the beginning of a string and then find all rows that start with that string? Or, do you just want to let them find when it matches the string. This is one way if you want to do matching:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(32767);
q varchar2(32767);
BEGIN
-- Change the : separate string to be comma separated with quoted strings
s := '''' || replace(:P50_SELECTED_INSTRUMENTS, ',', ''',''')|| '''' ;
-- htp.p('COUNT: '||selected_items.count);
q:= 'SELECT '||
'SUBSTR(orig_geo_loc_sys,1,INSTR(orig_geo_loc_sys,''-'')-1) AS INSTRUMENT, '||

If you want to do something more like you originally stated, try this:
DECLARE
selected_items HTMLDB_APPLICATION_GLOBAL.VC_ARR2;
s VARCHAR2(20);
q varchar2(32767);
BEGIN
selected_items := HTMLDB_UTIL.STRING_TO_TABLE(:P50_SELECTED_INSTRUMENTS);

q:= 'SELECT '||

' (orig_geo_loc_sys)) AS ORIG_LINENUM, '||
'sum(orig_intrl) orig_intrl, '||

FOR i in 1..selected_items.count LOOP
s := TO_CHAR(selected_items(i));
q := q || ' and TO_CHAR(orig_geo_loc_sys) LIKE '''|| s ||'%'' ' ;
END LOOP;
q := q || ||'%'' '||

Pl/sql function body returning SQL query - Print function

Hello all,
I have pl/sql function body returning SQL query for my reports for my new project that I am developing. We dont have any BI tool or anything for APEX so we use Oracle reports to get the same reports to be printed in PDF format. I had been using SQL function for Reports all these days and grabbing the data using SQL query was easy in Oracle reports. But this time we had atleast 8 fields in search criteria and hence I thouhgt PL/sql function body returning SQL query could be something easy to handle that scenario. We have 11 such reports in our project. Now when we tried to use the same PL/sql function to oracle reports , I was told by one of our Oracle reports expert, that we have to write it into functions and use it in SQL query to get the Reports in Oracle reports. Is there any Easy way to convert the same Pl/SQL function or get a PDF format of the same report in APEX without going thru the much pains of rewriting the whole SQL Query.
thank you

Query on Reoprts-pl/sql function body returning sql query

Hi,
I am facing a starnge problem.. and would like to know the reason for it.
The situation is as follows:
I have a report (pl/sql function body returning sql query based). My query is as follows:
declare
l_query1 varchar2(2000);
begin
if (:P102_min_value is not null and :P102_max_value is null) then
l_query1 := 'select decode(:P102_date,'1',date1) Transaction_Date, decode(:P102_first_name,'2',first_name) First_Name from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=:P102_min_value
return (l_query1);
end if;
end;
This returns the error as :
1 error has occurred
Function returning SQL query: 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-06550: line 7, column 20: PLS-00103: Encountered the symbol "1" when expecting one of the following: * & = - + ; < / > at in is mod remainder not rem <> or != or ~= >= <= <> and or like LIKE2_ LIKE4_ LIKEC_ between || multiset member SUBMULTISET_)
How do i correct this? am i right in thinking that the single quotes indicating a string within a select query is creating the problem? Beacuse if i use an sql query report and use the following query, it is working fine...
select
decode(:P102_date,'1',date1) Transaction_Date,
decode(:P102_first_name,'2',first_name) First_Name
from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=:P102_min_value
But i need to write pl/sql function, so that multiple report can be returned based on different conditions. Please guide me.
Thanks,
Sumana

Does that mean that both in if and else we need to have same columns selected?
if thats the case.. any idea how i can implement it in my code. The situation here is that the columns that need to be selected are dynamic and keep on changing...
if i try to implement like this and run the page, it gives the following error:
Query is:
declare
l_query1 varchar2(4000);
begin
if apex_application.get_current_flow_sgid(:APP_ID) = apex_application.get_sgid then
if (:P102_min_value is not null and :P102_max_value is null) then
l_query1 := 'select decode(' || :P102_date|| ',''1'',date1) Transaction_Date, decode(' || :P102_first_name || ',''2'',first_name) First_Name from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=' || :P102_min_value ||'
elsif (:P102_min_value is null and :P102_max_value is not null) then
l_query1 := 'select decode(' || :P102_date|| ',''1'',date1) Transaction_Date, decode(' || :P102_first_name || ',''2'',first_name) First_Name from (
select * from MORTGAGE_LOAN_LEADS where APPRX_LOAN_AMOUNT >=' || :P102_max_value ||'
else
l_query1 := 'select date1,first_name from MORTGAGE_LOAN_LEADS where rownum = 1';
end if;
else
l_query1 := 'select date1,first_name from MORTGAGE_LOAN_LEADS where rownum = 1';
end if;
return l_query1;
--dbms_output.put_line( l_query1);
end;
The Error is:
failed to parse SQL query:
ORA-00936: missing expression
If i try to run the same in command prompt, it always goes to the else part... (else of outer if)

SQL Query (PL/SQL function body returning SQL query) when using to_char

we are trying to build a report page of Type SQL Query (PL/SQL function body returning SQL query).
our query is so simple, we need to extract the month from the recording_date column.
declare
l_query varchar2(1000);
begin
l_query:='select to_char(recording_date,'MM')from re_productive';
return l_query;
end;
but we are having the following problem for this query
Function returning SQL query: 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-06550: line 4, column 42: PLS-00103: Encountered the symbol "MON" when expecting one of the following: . ( * @ % & = - + ; < / > at in is mod remainder not rem <> or != or ~= >= <= <> and or like between || multiset member SUBMULTISET_ The symbol ". was inserted before "MON" to continue.)
Notes:
1-the query is correct and it was tested under Toad and SQL Plus.
2- we tried Use Generic Column Names (parse query at runtime only) option but we get the same problem.
any quick help please.

Hi
You haven't escaped your quotes in the string. Try this...
DECLARE
l_query VARCHAR2(32767);
BEGIN
l_query:= 'select to_char(recording_date,''MM'') from re_productive';
RETURN l_query;
END;Cheers

SQL Query (PL/SQL Function Body returning SQL query) doesn't return any row

I have a region with the following type:
SQL Query (PL/SQL Function Body returning SQL query).
In a search screen the users can enter different numbers, separated by an ENTER.
I want to check these numbers by replacing the ENTER, which is CHR(13) || CHR(10) I believe, with commas. And then I can use it like this: POD IN (<<text>>).
It's something like this:
If (:P30_POD Is Not Null) Then
v_where := v_where || v_condition || 'POD IN (''''''''||REPLACE(''' || :P30_POD || ''', CHR(13) || CHR(10), '','')||'''''''''')';
v_condition := ' AND ';
End If;
But the query doesn't return any rows.
I tried to reproduce it in Toad:
select * from asx_worklistitem
where
POD IN (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
==> This is the query that does't return any rows
select (''''||REPLACE('541449200000171813'||CHR(13) || CHR(10)||'541449206006341366', CHR(13) || CHR(10), ''',''')||'''')
from dual;
==> This returns '541449200000171813','541449206006341366'
select * from asx_worklistitem
where pod in ('541449200000171813','541449206006341366');
==> and when I copy/paste this in the above query, it does return my rows.
So why does my first query doesn't work?
Doe anyone have any idea?
Kind regards,
Geert

Thanks for the help.
I made it work, but via the following code:
If (:P30_POD Is Not Null) Then
v_pods := REPLACE(:P30_POD, CHR(13) || CHR(10));
v_where := v_where || v_condition || 'POD IN (';
v_counter := 1;
WHILE (v_counter < LENGTH(v_pods)) LOOP
v_pod := SUBSTR(v_pods, v_counter, 18);
IF (v_counter <> 1) THEN
v_where := v_where || ',';
END IF;
v_where := v_where || '''' || v_pod || '''';
v_counter := v_counter + 18;
END LOOP;
v_where := v_where || ')';
v_condition := ' AND ';
End If;But now I want to make an update of all the records that correspond to this search criteria. I can give in a status via a dropdownlist and that I want to update all the records that correspond to one of these POD's with that status.
For a region you can build an SQL query via PL/SQL, but for a process you only have a PL/SQL block. Is the only way to update all these records by making a loop and make an update for every POD that is specified.
Because I think this will have a lot of overhead.
I would like to make something like a multi row update in an updateable report, but I want to specify the status from somewhere else. Is this possible?
