Problem with PL/SQL Function Body

Hi,
I'm getting the following error, when i run the report.
I'm trying to fetch a year value from a table based on a parameter value ":P33_YEAR"
ORA-01403: no data found
Error ERR-1904 Unable to compute item default: type = Function Body computation_type= DECLARE FY VARCHAR2(6); BEGIN SELECT DISTINCT YEAR1 INTO FY FROM REP WHERE YEAR = TRIM(:P33_YEAR);
RETURN FY; END;.
I have written this code in a PL/SQL Function Body for a Hidden item.
Please let me know whats wrong with this code?
Thanks
CK

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..

Populating item with pl/sql function body

Hi,
I want to populate a "Display as text (saves state)" item with the difference of 2 other items.
The source of my item is:
- Only when current...
- PL/SQL Function body
- Source expression:
DECLARE
v_diff NUMBER;
BEGIN
v_diff := :P1_AUFWAND_TOTAL - :P1_AUFWAND_BERECHNET;
return v_diff;
END;
Now I get this error:
ORA-06502: PL/SQL: numerischer oder Wertefehler: Fehler beim Konvertieren von Zeichen zu Zahl
Error ERR-1904 Unable to compute item default: type = Function Body...
I tried to track down the problem with to_number conversion:
v_diff := to_number(':P1_AUFWAND_BERECHNET'); or
v_diff := to_number(':P1_AUFWAND_BERECHNET', '999G999D00');
What's wrong here? It feels like I'm making a simple mistake...
Thanks for any help,
Roger

Hi Denes,
Thanks for your help. You were right, item :p1_aufwand_berechnet was not a number.
I created the problem myself by setting the format to:
return TO_CHAR(v_aufwand,'999G999G999G999G990D00');
Now the dilemma is that I want to calculate the numbers, but at the end I want a nice format to display them. This obviously only works with TO_CHAR, see:
Re: Number format mask of text item is not applied
Maybe this is to be solved with a seperate process after the calculation, to set the format?
Cheers,
Roger

Problem with extended SQL functions in RTF Template

Hello,
I'm new to BI Publisher and I'm trying to create a new rtf template. I've created my layout and added fields without any problems, but I'm having trouble trying to insert calculations such as add,substract,multiply,divide, etc.
Here is an example of what I'm trying to do:
<?xdofx:STAFF_ASMT+100?>
Where STAFF_ASMT is one of my fields. When I add this function all I get is the actual value from that field returned on the first page, and then on other pages I get the value plus an extra zero.
So with my example data below I get: 6600 on page 1 and 51830 on page 2. Any ideas on what I'm doing wrong or if it is possible to do what I'm doing? Also, is it possible to add/substract/multiple two or more fields together?
Something like this: <?xdofx:STAFF_ASMT+GROSS_INV?>
I was going to add all of these functions to my SQL statement, but I have 30 or so calculations I want to perform in the layout and I don't want to have to write that all out in SQL.
<ROWSET>
<ROW>
<STAFF_ASMT>6600</STAFF_ASMT>
<GROSS_INV>0</GROSS_INV>
</ROW>
<ROW>
<STAFF_ASMT>5183</STAFF_ASMT>
<GROSS_INV>0</GROSS_INV>
</ROW>
</ROWSET>

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".

Sql query(PL/SQL function body return SQL query) with in(x,y,z) condition

Hello,
I've set up a region definition of type "SQL Query(PL/SQL function body return SQL query). In my query I make use of an "in" condition. When I populate :P755_INC_BARG_UNIT with a value of 0F (no quotes), I get the correct count. However, when I set :P755_INC_BARG_UNIT to 0F, 0E I get an invalid count. What do I have to set the page item to?
When running the query in TOAD, and setting :P755_INC_BARG_UNIT to the string inside the brackets (0F, 0E) I get the proper count.
The code I use is shown below. Any help would be appreciated,
Alex.
DECLARE
v_sql VARCHAR2(32767);
BEGIN
SELECT count(*) "cnts",
''Faculty data file IDs missing in appt table'' "err_type"
FROM hradmin.et_faculty_salary fs left outer join
hradmin.appointments appt
ON trim(fs.empl_id) = appt.emp_emp
and appt.ear_activ <> ''Z''
and appt.ear_type = ''F''
and (appt.ear_class in (''A'',''B'',''C'',''D''))
and appt.ear_bargunit in ( :P755_INC_BARG_UNIT )
WHERE appt.emp_emp is null
RETURN v_sql;
END;

Alex,
try something like:
DECLARE

BEGIN
v_sql := <YOUR_SQL_STATEMENT_WITH_P755_INC_BARG_UNIT_IN_IT>;
v_sql := REPLACE(v_sql, ':P755_INC_BARG_UNIT',:P755_INC_BARG_UNIT);

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:

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).

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.

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 ......
Thnks in advence

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)?

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.

How to use a select list value in a PL/SQL function body returning SQLquery

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?

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, '||
'SUBSTR(orig_geo_loc_sys,INSTR(orig_geo_loc_sys,''-'')+1, LENGTH'||
' (orig_geo_loc_sys)) AS ORIG_LINENUM, '||
'sum(orig_intrl) orig_intrl, '||
'sum(orig_extrl) orig_extrl, '||
'sum(recv_intrl) recv_intrl, '||
'sum(recv_extrl) recv_extrl '||
'FROM line_usage_sum_view '||
'WHERE TO_CHAR(orig_geo_loc_sys) in (' || s ||' ) '||
--'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''2213003%'' '||
'AND switch_id = ''' || :P1_SWITCH_ID || ''' ' ||
'AND call_start_date > TO_DATE(''30-NOV-1999'') ' ||
'AND call_clear_time > TO_DATE(''30-NOV-1999'') '||
'AND '||
:SORTFIELD||' BETWEEN '||
'TO_DATE(:STARTDATE,''dd-MON-YYYY HH24:MI'') AND '||
'TO_DATE(:STOPDATE, ''dd-MON-YYYY HH24:MI'') '||
'GROUP BY GROUPING SETS (orig_geo_loc_sys)';
-- htp.p('SQL query: '||q);
RETURN q;
END;
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);
-- htp.p('COUNT: '||selected_items.count);
q:= 'SELECT '||
'SUBSTR(orig_geo_loc_sys,1,INSTR(orig_geo_loc_sys,''-'')-1) AS INSTRUMENT, '||
'SUBSTR(orig_geo_loc_sys,INSTR(orig_geo_loc_sys,''-'')+1, LENGTH'||
' (orig_geo_loc_sys)) AS ORIG_LINENUM, '||
'sum(orig_intrl) orig_intrl, '||
'sum(orig_extrl) orig_extrl, '||
'sum(recv_intrl) recv_intrl, '||
'sum(recv_extrl) recv_extrl '||
'FROM line_usage_sum_view '||
'WHERE 1=1 ';
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 || ||'%'' '||
--'WHERE TO_CHAR(orig_geo_loc_sys) LIKE ''2213003%'' '||
'AND switch_id = ''' || :P1_SWITCH_ID || ''' ' ||
'AND call_start_date > TO_DATE(''30-NOV-1999'') ' ||
'AND call_clear_time > TO_DATE(''30-NOV-1999'') '||
'AND '||
:SORTFIELD||' BETWEEN '||
'TO_DATE(:STARTDATE,''dd-MON-YYYY HH24:MI'') AND '||
'TO_DATE(:STOPDATE, ''dd-MON-YYYY HH24:MI'') '||
'GROUP BY GROUPING SETS (orig_geo_loc_sys)';
-- htp.p('SQL query: '||q);
RETURN q;
END;
Hope this helps...

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)?

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)
