PL/SQL function in datamodel query

Hi All,
I have the following problem:
I have a query Q1 returning a few rows. In the group G1 using this query Q1 i have a computed field returning a number NUM_1.
select col_1, col_2 from table_1;
So the output looks like:
row 1 col_1 col_2 NUM_1_1
row n col_1n col_2n NUM_1_n
I want to order these rows by the calculated column NUM_1 the highest first.
I know i can't order by a calculated column but can i do it by using a pl/sql function in the query to calculate the NUM_1?
Like:
select col_1, col_2, function(x) NUM_1 from table_1;
And where should i create this function? Can it be done in the program unit section or do i have to create a library?
Best regards,
Snoesky

Oke, i have created a break group on the calculated field.
Ordering works fine now.
I have an additional question:
Is it possible to dynamically order this break (column) group? Meaning thru a parameter to tell the ordering to be descending or ascending.
Regards,
Snoesky

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);

Appreciate your help in this regard.

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)?

Column order in SQL Query (PL/SQL function returning a query)

Hi,
when I define a PL/SQL function returning a query inside a region, I often find that the column order is arbitrarily changed.
How do I enforce the column order ?
Bye,
Flavio

I removed the 11th column called service_name from this dynamic query: and now the report says: report error:
ORA-01403: no data found. I messed around with the Headiuns Type. It was set to Custom. I changed it to Column Names. There is no difference.
I am not sure how to fix?

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

SQL Functions Supported by RDBMS Adapter

Hi,
Where can I find the list of SQL Functions supported by RDBMS Adapter?
I am retrieving date from Oracle 9i using RDBMS Adapter 8.1 SP2.However when I use any SQL Function (like to_char, to_date) in select query the service creation fails with a parsing exception.
Please help me resolving this.I want a date to be selected as a string in a particular format.
Thanks,
Vishvjit

Sorry,just got the resolution in Known Limitations of the adapter Release Notes. Actually we have to create a service of arbitory sql for using SQL Functions in the query.

Report- Pl/sql function returning sql query parsing page items as text?

Hi Team,
I am facing a strange issue .
I have four page items namely
1)JOB_CODE
2)MIN_EXP
3) MAX_EXP
4) SOURCES1
I have a report of the type "Pl/sql function returning sql query"
declare
v_sql varchar2(4000);
begin
if (:JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql:= 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:JOB_CODE IS NULL and :MIN_EXP IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MIN_EXP IS NULL and :JOB_CODE IS NOT NULL and :MAX_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where v_experience_years <= :MAX_EXP and V_REQUIREMENT = :JOB_CODE and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
elsif (:MAX_EXP is null and :JOB_CODE IS NOT NULL and :MIN_EXP IS NOT NULL and :SOURCES1 IS NOT NULL) then
v_sql := 'select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and source like ' || '''' || '%'|| ':SOURCES1' || '%' || '''';
end if;
insert into query_list values (v_sql);
insert into debug values (:JOB_CODE , :MIN_EXP , :MAX_EXP , :SOURCES1);
return v_sql;
end;
Please not that I am insertin the query into a table called Query_list and the page item values into the table called Debug thru the pl/sql function which returns teh query.
Now I select the data from the debug tables.
select unique(query) from query_list;
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = :JOB_CODE and v_experience_years >= :MIN_EXP and v_experience_years <= :MAX_EXP and source like '%:SOURCES1%'
select * from debug;
JOBCODE     MINEX     MAXEX     SOURCE
21     1     10     donkeyHire
And if I run the query in sql I get some records returned
select v_candidate_id, v_fname,v_current_employer,v_Experience_years from candidature where V_REQUIREMENT = 21 and v_experience_years >= 1 and v_experience_years <= and source like 'donkeyHire'
V_CANDIDATE_ID     V_FNAME     V_CURRENT_EMPLOYER     V_EXPERIENCE_YEARS
2     Vengu     Andale Tech     4
But the record does not show up in the report!
does this type of report parse page items as text?
Why is it so?
Waiting for an early reply.
Thanks,
venkat

Venkat - You don't want to put ':SOURCES1' in quotes like that.

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 ......

Issue with running PL/SQL function returning Sql query

hi, I am trying to create a report region by using the option of PL/SQL function returning sql query.
I notice that it's very slow for the report region page to show up. In my PL/SQL function body, there are only 3 steps, first update all the 10 rows of varchar2 fields to null,then insert values to those fields, then select all from the table to show report results. It takes more than 5 minitues for the page to load up, how ever, if i run those steps in SQL*Plus, it only takes a couple of seconds to finish. Any suggestions?
Thanks,
gina

Sergio, the codes are as followed,
Declare
q varchar2(32767); -- query
Begin
q := 'select "ID",'||
'"ENTRY NAME","TOTAL","#CM","%CM","#CA",'||
'"%CA", from Info_table';
update info_table
set "TOTAL" = '',
"#CM" = '',
"%CM" = '',
"#CA" ='',
"%CA"=''
where "ID"<=10;
// set all data in column Total to null,there is only 10 rows in the table
update info_Table set Total = vTotal,
"#CM" = vCM
(those variables hold user key-in Text filed value)
where ID = 1;
return q;
End;

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...

On Submit process not firing -report (PL/SQL function returning SQL query)

Can anyone suggest possible causes / solutions for the following problem?
I have a report region that uses a PL/SQL function returning SQL query. The report allows the user to update multiple fields / rows and then click a button to submit the page which should run the On-Submit process to update the database. However the process does not run and I get a 'HTTP404 page cannot be found' error; and when I navigate back using the Back button I cannot then navigate to any other page in my application without getting the same error. The button was created by a wizard selecting the options to submit the page and redirect to a (same) page. The button does not actually have a redirect in its definition but the wizard created a branch to the same page which should work and the button has the text 'submit as SUBMIT' next to it so it appears to be set up correctly.
I have recreated this page several times in my application and I cannot get the On-Submit process to run. However I have created a cut down version of the same page in the sample application on apex.oracle.com at http://apex.oracle.com/pls/otn/f?p=4550:1:179951678764332 and this works perfectly so I am at a loss to understand why it does not work in my application. I cannot post any part of the application itself but if anybody would like to check out page 30 of the sample application (Customer Update Test tab) updating the surnames only, using credentials ja, demo, demo this is pretty much what I have got in my application.
Any ideas would be much appreciated?

Thanks for the suggestions guys. I have now identified that the problem goes away when I remove the second table from my report query. The original report query retrieved data from two tables and the process was updating only one of the tables. I thought I had approached the task logically i.e. first get the report to display the records from the two tables, then get the process to update the first table and finally to modify the process further to update the second table.
Can anyone point me to an example of multiple row updates on multiple tables using a PL/SQL function returning an SQL query?

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

SQL Query(PL/SQL Function Returning SQL Query)

I am trying to write a dynamic report using SQL Query(PL/SQL Function Returning SQL Query).
I can get the report to run but I need to concatinate some columns into one, seperated by a comma or a dash.
I have tried select *****||','||***** alias
also select *****||'-'||***** alias
but I always get an error.
Is there a way of doing this please
Gus

This is my full query
declare
v_query varchar2(4000);
begin
if :P63_TRAN_INFO = 2 THEN
v_query := 'select
     A.FILENR,
     A.EXERCISENAME,
A.STARTDATE,
A.ENDDATE,
     A.UNIT,
A.ACCADDRESSES, B.ADDRESS, B.ADDRESS_1, B.POST_CODE, B.TOWN,
     A.EXERCISEAREAS,
     A.TOTALVEHICLES,
A.TOTALTROOPS+A.RNTOTALTROOPS+A.RAFTOTALTROOPS TOTALTROOPS,
A.CAR, A.MINIBUS, A.HGV,
A.NAMERANK, A.ADDRESS, A.ADDRESSI, A.ADDRESSII, A.POSTCODE,
A.TRANSIT,
A.INFOONLY
from     BFLOG_AT A, BFLOG_ACCADDRESS B
WHERE A.ACCADDRESSES = B.NAME
AND A.STARTDATE >= :P63_START_DATE
AND A.ENDDATE <= :P63_END_DATE
AND A.AUTHORISED = 1
AND A.INFOONLY = 1' ;
END IF;
RETURN v_query;
END;
This query runs ok, but if I try changing it to the code below with fields concatinated, then it fails
declare
v_query varchar2(4000);
begin
if :P63_TRAN_INFO = 2 THEN
v_query := 'select
     A.FILENR,
     A.EXERCISENAME,
A.STARTDATE,
A.ENDDATE,
     A.UNIT,
A.ACCADDRESSES||','||B.ADDRESS||','||B.ADDRESS_1||','||B.POST_CODE||','||B.TOWN ADDRESS,
     A.EXERCISEAREAS,
     A.TOTALVEHICLES,
A.TOTALTROOPS+A.RNTOTALTROOPS+A.RAFTOTALTROOPS TOTALTROOPS,
A.CAR, A.MINIBUS, A.HGV,
A.NAMERANK, A.ADDRESS, A.ADDRESSI, A.ADDRESSII, A.POSTCODE,
A.TRANSIT,
A.INFOONLY
from     BFLOG_AT A, BFLOG_ACCADDRESS B
WHERE A.ACCADDRESSES = B.NAME
AND A.STARTDATE >= :P63_START_DATE
AND A.ENDDATE <= :P63_END_DATE
--AND (A.EXERCISEAREAS LIKE "GAP, OA, OAL")
--OR (A.EXERCISEAREAS LIKE "Harz")
AND A.AUTHORISED = 1
AND A.INFOONLY = 1' ;
END IF;
RETURN v_query;
END;
