Conditional display using Pl/SQL function body returning a boolean

I am having issues with conditional display of a report.
I have to select lists: p50_facility and p50_supervisor.
I have entered the below pl/sql function body returning a boolean
Begin
if (:p50_facility is null or
:p50_supervisor is null) THEN
Return False;
Else
Return True;
End if;
End;
No matter what values my items are set to (null, not null), the report shows.
What am I doing wrong?

Hi,
The values for the lists will be null only until the first time the page is submitted. Thereafter, the value is likely to be '%null%'
You will need to do something like:
BEGIN
IF (:P50_FACILITY IS NULL OR :P50_FACILITY = '%' || 'null%' OR :P50_SUPERVISOR IS NULL OR :P50_SUPERVISOR = '%' || 'null%') THEN
RETURN FALSE;
ELSE
RETURN TRUE;
END IF;
END;Andy

Conditional display: PL/SQL Function Body Returning a Boolean

Hi,
can anyone give me an example how to create a PL/SQL Function Body Returning a Boolean in the Conditional Display Section of a Region?
I have two Items on the Page and I want the region only be displayed when the two Items are not null....
Thanks,
tim

Also, I have seen some "null"-values of Selectlists being stored as '%null%' instead..
:P1_ITEM1 IS NOT NULL AND UPPER(:P1_ITEM1) != '%NULL%' AND :P1_ITEM2......
..might be helpful?

Item null when using PL/SQL function body returning SQL query

I have an item P5_CUSTOMER_ID (text). Whatever be the value I enter in this text box, the PL/SQL seems to execute the ELSE condition. What am I missing? I am using 2.0 and 10g Oracle.
Declare
qry VARCHAR2(1000);
Begin
IF :P5_CUSTOMER_ID IS NOT NULL THEN
qry := 'select :P5_CUSTOMER_ID as NOT_NULL from dual';
ELSE
qry := 'Select :P5_CUSTOMER_ID as NULL_NULL from dual';
END IF;
return qry;
End;

I forgot to mention that P5_CUSTOMER_ID value is printed in the report. See my Select statement). When I enter '10' in the text box, the SQL output prints it under the column heading 'NULL_NULL'. Since it recognizes the value, it should execute the IS NOT NULL condition, but it does not.

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
v_sql VARCHAR2(32767);
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);
RETURN v_sql;
END; But before doing it read this:
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:210612357425
After reading you will be able to find the best solution yourself.

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

Using Package to produce pl/sql function body returning sql query Report

I have existing code that we want to use in building reports in APEX. We are needing to modify it slightly to handle some new requirements, but would like to use them in reports based upon SQL query (pl/sql function body returning sql query) functionality.
Any suggestions as how to call these in an APEX report region?
Thank you,
Tony Miller
UTMB/EHN

Hi Tony-
I am also v new to Apex and you may have answered a question I was in search of. I, however, now have a couple more. First a bit of background-- Like in your situation, my college has a lot of existing code (400 +) that we need to get into Apex. The majority of this canned code contains one/both: 1) many lines, sometimes containing multiple select statements 2) imbedded create table & view statements (temp user owned). Up until reading your post, I was unable to figure out an easy way of getting this existing code into the product. Thanks. Now the questions, do you know how I would go about dealing with the create tables/views. I've read some posts on this forum which suggest temporary tables being unstable in this environment. Also, do you know if there's a size limitation when passing sql code via a function?
As you may/may not be able to tell, I'm a bit lost right now... so any info you can provide would be appreciated. Thanks.

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

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.

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

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

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)

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.

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)';

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)?

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
