Pass a list of number values to a pl/sql function
I would like to pass a list of number values to a pl/sql function where the list will be used in an IN clause. Ideally I would like to do the following:
CREATE OR REPLACE FUNCTION ( dept_list in varchar2) is
begin
select ... where dept in (dept_list) ;
usage: process_list ( '7730,7735,7740,7745') ;
I can not find an example of doing this in pl/sql function but it seems feasible.
Is there a way to do this?

usage: process_list ( '7730,7735,7740,7745') ;The first thing is you need an appropriate data type to store a list of numbers. A single character value that looks to you like a list of numbers, is not in fact a list of numbers but a single character value.
This example uses the built in data type odcinumberlist in a procedure, you can do the same in function
Re: Passing an array to an Oracle stored procedure
If you have an old version of the database you may need to create your own type with the same definition of odcinumberlist.

Pass a value from a PL/SQL function to a javascript (html header) ? ?
Hey Guys,
Have a question regarding how to pass a value from a PL/SQL function to a javascript in the HTML Header.
I have created a PL/SQL function in my database, which does looping.
The reason for this is: On my apex page when the user selects a code, it should display(or highlight buttons) the different project id's present for that particular code.
example= code 1
has project id's = 5, 6, 7
code 2
has project id's = 7,8
Thank you for your Help or Suggestions

I have made the following modifications to your app to get it to work as I thing you need it to.
1) Changed the source for the HTML Buttons Region(note use of id vs name for the Buttons)
<script>
function hilitebtn(val) {
//gray buttons
$x('graduate').style.backgroundColor='gray'
$x('distance').style.backgroundColor='gray'
$x('career').style.backgroundColor='gray'
$x('photo').style.backgroundColor='gray'
//AJAX call to get project-ids
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=GETPROJECTS',0);
get.addParam('x01',val)
gReturn = get.get();
var arr=gReturn.split(':'); //dump into array
get = null;
for (i=0;i<arr.length;i++) {
// alert('val=' + arr);
if ( arr[i]==5)
$x('graduate').style.backgroundColor='red';
if ( arr[i]==6)
$x('distance').style.backgroundColor='red';
if ( arr[i]==7)
$x('career').style.backgroundColor='red';
if ( arr[i]==8)
$x('photo').style.backgroundColor='red';
</script>
<table cellpadding='0' cellspacing='0' border='0'>

</td>
<td>
<input type='button' id='career' value='Career/Tech'>

<td>
<input type='button' id='photo' value='Photos'>

</tr></table>
2) Defined the application process GETPROJECTS as DECLARE
IDS varchar2(1000);
l_act_code varchar2(100) :=4;
begin
IDS:='';
l_act_code := wwv_flow.g_x01;

SELECT ACT_CODE,PROJECT_ID
FROM ASQ_CONTACT
where ACT_CODE = l_act_code)
LOOP
IDS := IDS || X.PROJECT_ID|| ':' ;
END LOOP;
HTP.PRN(IDS);
END;
3) Changed the 'onchange' event-handler on p1_act_code to be 'onchange=hilitebtn(this.value)'
4) Added the JS to the HTML Page Footer <script>
hilitebtn($v('P1_ACT_CODE'));

Using return value of a pl/sql function in the "where" coarse in a
Hi,
I have a question,
if I have a pl/sql function that returns a boolean value, how can I use
it directly in a select statement?
I can easily do this if the function returns a number value , e.g.
select * from my_table where my_package.function('abc') = 1;
But I can't figure out how to do this if the function return a boolean.
Any idea other than creating another function?
Please reply to me directly as I'm not in the email list. Thanks.BOOLEAN is not a SQL datatype - you can only reference Boolean values in PL/SQL.

Need to pass value from check box to the pl/sql function in process
My requirement is to use single value check box and pass the flag value to the pl/sql function.
The function need to interpret the flag and execute accordingly.
In this case checkbox name is P1_DELETE and it returns Delete, if checked.
Anonymous block with in the process looks as follows:
declare
l_result VARCHAR2(1024);
begin
l_result := test_function(:P1_DELETE);
end;Hi Visu,
checkboxes in APEX are handled as arrays, namely APEX_APPLICATION_GLOBAL.VC_ARR2. To pass and process the checked values of checkboxes in a pl/sql function or procedure you could use the following way, assuming you have a checkbox named P1_DELETE with a single return value of "Delete"
DECLARE
l_checkbox_values apex_application_global.vc_arr2;
BEGIN
l_checkbox := :P1_DELETE;
-- calling function test_function processing the value
test_function(NVL(l_checkbox(1), 'SOME_OTHER_VALUE'));
END;If the checkbox is not checked then the array at position 1 is null and you have to process that as you like.
If your checkbox would be a group than the array would be colon separated such as 1:2:3:4 etc. and you would have to loop the array like:
FOR idx IN 1..l_checkbox.COUNT LOOP
test_function(l_checkbox(idx));
END LOOP;Hope that helps.

Problem with empty report parameters when passed to PL/SQL function
Hi,
We have come across what appears to be a bug in the JRC. When passing a report parameter to a PL/SQL function as a parameter, empty parameters are changed before being sent to the function. More specifically, an empty string "" ends up as the value "(')" in the PL/SQL function parameter. In our report we print the report parameters on the first page so we know that the parameters are OK before being passed to the database.
The problem exists for version 12.2.203, 12.2.204 and 12.2.205 of the JRC.
We have identified a workaround, but it is not exactly elegant: Before executing the report we modify all empty parameters ("") to " " . In the PL/SQL function, we trim all parameters before using them.
We call the function using a command object with a sql syntax like this example:
select * from table (qa_batch_release.get_qa_br('{?p_report_id}','{?p_reg_set_number}','{?p_cr_number}','{?p_change_id_decode}','{?p_country_id}','{?p_mfg_item_no}','{?p_4_no}','{?p_5_no}','{?p_7_no}'))
The PL/SQL function is a table returning function.
Best regards, ThorHi Kishore,
using #COLUMN_VALUE# would probably not make much sense, because normally a report has multiple columns and not just the numeric column which you want to verify if it's negative. But APEX will fire the template condition for each column, because the report template is a column cell template.
What you can do to make it more generic is to use for example
#CHECK_AMOUNT#
in the template and provide a not displayed column in your SQL statement which contains your value which is named CHECK_AMOUNT. For example:
SELECT NAME
, BALANCE
, BALANCE AS CHECK_AMOUNT
FROM XXX;Because this CHECK_AMOUNT column would be a generic name, you can use this template in all your reports as long as you provide this column.
Thope that helps

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,
LauraLaura,
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 '||

'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;

PL/SQL Function call error while reading or assigning returned value
Hi,
I am getting the following error while tryih to read the value of the PL/SQL Function. I am calling a function in one of my PL/SQL Packages passing mutliple IN parametes and the function returns some value back. Now on BPEL side when I try to read the return value I am getting an error:
*<summary>*
empty variable/expression result.
xpath variable/expression expression "/ns3:OutputParameters/ns3:TEST_FUNCTION" is empty at line 124, when attempting reading/copying it.
Please make sure the variable/expression result "/ns3:OutputParameters/ns3:TEST_FUNCTION" is not empty.
*</summary>*
Even though in the console when I check the Invoke Output Parameter it does shows me a valid value being retuned by a Function but when I am trying to Assgn this value to some variable using Assign Activity I get the above error.
Even though all goes fine but looks like I am not able to read or assign the value returned from the Function.
So just wondering if this even works as to me I have a very simple example and that seems not to work. Function is called successfully and is returning the value as I can see it in the BPEL console but when tryin to read or assign that value to some other variable I get the above error.
Any ideas?
ThanksThis issue has come up a lot. The problem is with a mismatch between the version of JDeveloper and SOA. You'll encounter namespace issues if you use 10.1.3.1 in combination with 10.1.3.3 (or 10.1.3.4). You MUST synchronize both JDev and SOA to 10.1.3.3 or 10.1.3.4 (mixing 10.1.3.3 and 10.1.3.4 is OK). We changed when going to 10.1.3.3 by adding elementFormDefault="qualified" to the generated XSD. We used the default "unqualified" in 10.1.3.1. So you'll encounter namespace issues unless you're using 10.1.3.3 or higher JDev AND SOA. The fact that I see <*db:*...> tells me that you're using 10.1.3.1 JDeveloper. The correct solution is to upgrade your components.

Data passed from Java to a PL/SQL function
OK, I am at the beginner-to-intermediate level when it comes to PL/SQL...and a virtual novice when it comes to Java, so please forgive me if my question seems strange or naive.
We are developing a Java-based web app. Some of the screens are reminiscent of a spreadsheet-type layout--potentially LOTS of rows and LOTS of columns (actually, an open-ended # of rows/columns--the rows represent a particular 'thing' and the columns represent the dates on which that 'thing' occurred), where the user can check off any and all the cells that apply. We are also 'auditing' all database activity (who did what to the data, and when). The approach we have chosen is as follows: When the user clicks save, the first thing we do is 'inactivate' all of the existing active rows in the db for that screen, whether or not they have changed(i.e., there is an 'active' flag that we set to false & we also save the user id of the person making the change and the date time of the change). Then the Java code calls the database once per row/contiguous column unit. For instance, on a single row, if the user checks off columns 1-4 and 7-15 and column 21 the Java code will send three calls to the database for that row with info about the start/stop column for each unit.
OK--here is my concern...the majority of the time there will be a reasonably small #of 'units'. Occasionally there will be a moderate, and once in awhile a LARGE # of 'units'. So, let's take an extreme case and say that currently the db has 200 such row/contiguous column units for a given screen. The user goes into that screen and adds the 201st unit, then clicks Save. Java calls the db to first inactivate the 200 rows. Then one by one Java calls the db to add the rows back in, only on row #40, the internet connection is lost. The only way the user can tell what happened is to look at the entire screen and reverify ALL the data in order to tell what got saved/resaved and what didn't. Obviously this is a bad situation that we want to avoid.
I should add that the reason this approach was chosen is that the Java developers thought it would be way too complex in this situation to track the changes the user made on the screen, sort out what has been added/modified/deleted, and only call the db for changes.
So given this background, can anyone offer any suggestions/ideas on how we can prevent unintended data loss given the auditing constraints and concern about minimizing complexity on the Java side (redesigning the GUI screen is NOT an option, as the users are very attached to this design)?
Is there a way for Java to pass a multidimensional (& variable-sized) array to a PL/SQL function? Can Oracle's complex (row, table) data types be used in a function's parameter string, and if so...how?...Or else is there some way we can send a single call to the db on a screen like this one? We thought of calling the db once and sending one very large string packed with all the data (could get very big, not sure of Oracle's limatations on passed data--is it 32K for varchar2? )
Advice, ideas, even random thoughts would be greatly appreciated!Tracy,
<quote>⦠only on row #40, the internet connection is lost. The only way the user can tell what happened is to look at the entire screen and reverify ALL the data in order to tell what got saved/resaved and what didn't</quote>
That would be "the only way" if the Java programmers had decided to totally bury the error ⦠what should happen here is the end-user should get a proper error message ⦠no need to re-verify at this point since all bets are off (in fact, nothing shouldâve been changed in the database).
Nonetheless, your concerns regarding the chosen approach are valid ⦠making multiple calls to the database after a Save makes controlling a business transaction rather complex (in an n-tier system) ⦠they should make one call only to the database passing in all the data to be saved ⦠one database transaction ⦠either all changes get applied or none.
The fact that lots of data may need to be passed in for one Save is of no relevance ⦠if you have to carry 500Kb of data for that screen then, well, you have to do it ⦠1 bucket of 500Kb or 50 buckets of 10Kb? ⦠it doesnât really matter as far as the actual transport part is concerned.
As already answered, one can pass complex types in pl/sql ⦠so one database call per Save would be my first random thought. There are lots of suspect things in here ⦠some things you didnât mentioned at all ⦠like how is concurrency addressed? ⦠have you/they implemented some sort of optimistic locking mechanism? Of course the architecture of your system wonât be solved in a forum ⦠so, finding a good system/data/Oracle architect on site for the project would be my second random thought.
PS. One last random thought ⦠fight off that idea of packing and sending large strings (XML or not) ⦠if the data is structured then contemplate XML for no more than few seconds. -
Difficulty in using a variable to pass a list of names between 2 tables
Hi All,
I am trying to pass a list of names from one table as a variable to another table and trying to find the Highest level they exist at in the hierarchy. I am having some troubles with the variable and need some guidence and also if this should be a procedure or not.
this is what i have now :
Variable man_name Varchar;
exec :man_name = (Select full_name from direct_manager_report)
UPDATE direct_manager_report
Set Manager_level_number =
(Select 'Manager_Level_0' from manager_hierarchy where level_0_manager_name = man_name
UNION
Select 'Manager_Level_1' from manager_hierarchy where level_0_manager_name < > man_name AND level_1_manager_name = man_name
UNION
Select 'Manager_Level_2' from manager_hierarchy where level_1_manager_name < > man_name AND level_2_manager_name = man_name
UNION
Select 'Manager_Level_3' from manager_hierarchy where level_2_manager_name < > man_name AND level_3_manager_name = man_name
Where full_name = man_name;
Let me know what modifications have to be done for this the variable to get the name from table 1 and find the manager level from table 2 and populate it back in table 1.
Any help is appreciated.

Hi,Thanks for your reply. I am sorry for not providing enough information.
What's wrong with what you have now? I want to pass the manager name (about 2000) from direct_manager_report to the variable which i pass to manager_hierarchy table to find the highest level for each manager
If it doesn't give the right results, then how is anyone except you to know what the right results are?
Variable man_name Varchar;
exec :man_name = (Select full_name from direct_manager_report)Does that really work for you?No thats why i said this is what i have and i am trying to see the best to past the list of manager names to get the level number.
UPDATE direct_manager_report
Set Manager_level_number =
(Select 'Manager_Level_0' from manager_hierarchy where level_0_manager_name = man_name
UNION
Select 'Manager_Level_1' from manager_hierarchy where level_0_manager_name < > man_name AND level_1_manager_name = man_nameIt looks like something is missing on the line above. Did you mean "level_0_manager_name != man_name"?
This site doesn't like to display the <> inequality operator. Always use the other (equivalent) inequality operator, !-, when posting here.
UNION
Select 'Manager_Level_2' from manager_hierarchy where level_1_manager_name < > man_name AND level_2_manager_name = man_name
UNION
Select 'Manager_Level_3' from manager_hierarchy where level_2_manager_name < > man_name AND level_3_manager_name = man_name
Where full_name = man_name;Are you sure the UNION will never return more than 1 row?
Let me know what modifications have to be done for this the variable to get the name from table 1 and find the manager level from table 2 and populate it back in table 1.Whenever you have a problem, post a little sample data (CREATE TABLE and INSERT statements) and the results you want from that data (in this case, the contents of table1 after everything is finished).
See the forum FAQ {message:id=9360002}Sorry did not realize the missing !. Yes the union will always return one record for each manager name passed. I have tested the select part which hard coding the manager name and it does update the level number correctly. but i am struggling with passing a large list of values as a variable.
This is the output i am looking for in the direct manager report table is :
Manager Name | Manager Level Number
ABC Manager Level 0
XYZ Manager Level 1
This is the structure of the manager hierarchy:
Manager Level 0 Manager Level 1 Manager Level 2...Manager Level 14
ABC ABC ABC ABC
ABC XYZ XYZ XYZ
Let me try the below but hopefully i am more clear on the requirement now.

You may want something like this
MERGE INTO direct_manager_report dst
USING (
SELECT dmr.full_name

WHEN level_1_manager_name THEN '1'
WHEN level_2_manager_name THEN '2'
WHEN level_3_manager_name THEN '3'

ON ( dst.full_name = src.full_name )

How to pass a list of parameters to a query?
Hi,
I use OracleXE 10 Database with JDeveloper 11g.
In my project I use a Toplink mapping to get access to the database (Toplink Object Map file). This mapping xml file is called crmMap.xml.
In the crmMap.xml file I define a mapping to a "User table" which has the four columns id (number), title (varchar2), firstName (varchar2) and lastName (varchar2). A title can have the four values Bachelor, Master, Doctor and Professor.
I do define a query in crmMap.xml which has to find all the users that have a special title. I do give the query one parameter called "title" which has the type "java.util.ArrayList". The parameter "title" is a list that has for example the two values "Bachelor" and "Doctor", if I want to find all the users that are Bachelor or Doctor. The query looks like this ...
Select * from User where title in(?title)I do use an EJB Session Bean to call the query. The code looks like this ...
public List<User> findUserByStatus() {
Session session = getSessionFactory().acquireSession();
Vector params = new Vector(1);
List stati = new ArrayList();
stati.add("Doctor");
stati.add("Bachelor");
params.add(stati);
List<User> result = (List<User>)session.executeQuery("findUserByStatus", User.class, params);
session.release();
return result;
}Doing this I get an error, in the line
List<User> result = (List<User>)session.executeQuery("findUserByStatus", User.class, params);while the app is trying to execute the query.

Aufruf:Select * from User where title in(?title)
bind => [[Doctor,Bachelor]]Does anyone know a way how to pass a list of parameters
Thanks BodhyHi,
One alternative way is to create String with , sepearted as pass the string to in clause.For example ,create a string ('Bachelor','Doctor') and pass this string to in clause.
Session session = getSessionFactory().acquireSession();
String params=( 'Bachelor','Doctor);
List<User> result = (List<User>)session.executeQuery("findUserByStatus", User.class, params);
session.release();
This is an alternative way and workaround which can work for Strings .
Or you can use EXpression to build the query to pass the collection as example given below.
Expression addressExpression;
ReadObjectQuery query = new ReadObjectQuery(Employee.class);
ExpressionBuilder emp = query.getExpressionBuilder();
addressExpression =
emp.get("address").get("city").equal(
emp.getParameter("employee").get("address").get("city"));
query.setName("findByCity");
query.setSelectionCriteria(addressExpression);
query.addArgument("employee");
Vector v = new Vector();
v.addElement(employee);
Employee e = (Employee) session.executeQuery(query, v);
Hope this helps.
Regards,
Vinay Kumar
