PL/SQL function and aggregated items

Hi
I have created a PL/SQL function that returns a number. When I try to use this in a Discoverer report (via a calculation) I get a warning message saying that I am combining aggegated items and detailed items, and that this might return unexpected results.
Is there any way I can get this calculation to be an aggegated item?
I want the my crosstab to look something like this:
Date col1 col2 func1 func2
1 10 12 10 12
2 20 10 30 22
I also have some page items in the report. The PL/SQL functions display the correct number when a value is selected in the page items, but when I select <All> the numbers are not correct. Hopefully this will be solved when I solve the aggregate problem? Anyone who knows?
This is urgent, so I apriciate any response.
Thanks!

Calling PL/SQL Functions And Open Oracle Reports From ADF Application

Hi all,
My company will convert some projects from Oracle forms to Oracle ADF so, we need to call the PL/SQL functions and open the Oracle Reports (which are already exist) from ADF Application.
Thank You..

Item value not showing up in PL/SQL function on another item.

Basically, I am trying to update a database field based on the vaule of 2 other fields, but the item value dow not seem to get stored. No errors, it just shows up as a null value in the database. Here is the code inside the default area as a FL/SQL Function.
declare
P14_TNUM varchar2(255);
begin
select concat(mname,id) into P14_TNUM from T1,T2 where mid=:P14_TID;
return P14_TNUM;
exception when others then
return null;
end;
Note:
id is in T1
mname and mid is in T2
:P14_TID is the item which points to the pk in table T1

Anon,
I'm still a little confused as to what you're trying to do. Could you please take a little bit to better explain?

SQL, PL/SQL functions, and ORA-04091 table is mutating

Dears,
Recently a question came up in an Oracle French forum about an insert/select that is throwing ORA-04091: table xxxx is mutating, trigger/function may not see it error in 11g while the same insert/select was working very well in 10g. The original poster gave a scenario that is easily reproducible. I am wondering what database release is correct the one throwing the error(11g) or the other one accepting the insert/select(10g)?

Conditional Display based on Function and Application Item?

I have a function within my DB that checks if the STAFF_ID (an application level item) is a "Super User" within my application. The function ("is_super-user") returns 1 if the STAFF_ID given is a Super User. (I am not using ApEx users/groups)
How would I call this function within the Conditional Display of a button?
I tried the following with no luck... (although it does not give me an error)
Conditional Type: PL/SQL
Expression 1: is_super_user(&STAFF_ID.)=1

Matt is that you? You're not makin it real easy to identify you by name...
The function ("is_super-user") returns 1...
That should be is_super_user (without quotes, of course).
Your previous attempt should have produced an error. But this should work:
Conditional Type: PL/SQL
Expression 1: is_super_user(:STAFF_ID)=1
...assuming the function has a varchar2 input parameter.
And then to make it secure, you'll want to make that application item Restricted so nobody can pass in a value from the page. This kind of condition is a good use of authorization schemes which you can name/create once and attach to all sorts of components throughout the app. Speaking of other components, you should protect DML processes using the same condition/authorization scheme because just because there is no button visible on the page doesn't mean someone can't put one there and submit the page anyway.

Using PL/SQL Function with CLOB types and a Java Source

Hi people.
I have some problems trying to use a function in pl/sql with a CLOB parameter to a java source function.
Here is the problem: I have to read a TXT file and return a CLOB with the data of the file. The reading is done with a java source function.
The problem is how to read the file without messing the content and return it to the pl/sql function?
Another problem: If I pass a CLOB as a parameter to a pl/sql function and have to write the content to a file, how to do it without screwing the EOL chars and so?
My code is:
/******** PLSQL FUNCTIONS ********/
function fn_gravaconteudoarquivo( pv_caminho in varchar2
, pv_nomearquivo in varchar2
, pc_conteudo in clob ) return varchar2 as language java
name 'Importacao.gravaConteudoArquivo(java.lang.String, java.lang.String, oracle.sql.CLOB) return varchar2';
function fn_lerconteudoarquivoclob( pv_caminho in varchar2
, pv_nomearquivo in varchar2 ) return clob as language java
name 'Importacao.lerArquivoClob(java.lang.String, java.lang.String) return clob';
/******** JAVA SOURCE FUNCTIONS *********/
public static String gravaConteudoArquivo(String caminho, String nomeArquivo, CLOB conteudo) {
File file = new File(caminho, nomeArquivo);
PrintWriter pwFile;
String mensagem = "";
StringBuffer sb = new StringBuffer();
try {
pwFile = new PrintWriter(new BufferedWriter(new FileWriter(file,true)));
for (int i=0;i<=(conteudo.length()/32000);i++) {
sb.append(conteudo.getSubString(conteudo.getLength()+1,32000));
pwFile.println(sb.substring(0));
pwFile.close();
} catch (Exception ex) {
mensagem = "Erro: "+ex;
return mensagem;
public static CLOB lerArquivoClob(String caminho, String nomeArquivo) throws SQLException {
File file = new File(caminho, nomeArquivo);
Connection conn;
CLOB clob = null;
String lineSep = System.getProperty("line.separator");
StringBuffer sb = new StringBuffer();
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:csdesv", "csestoque", "liberada");
clob = CLOB.createTemporary(conn, true, CLOB.DURATION_SESSION);
BufferedReader brFile = new BufferedReader(new FileReader(file.getPath()));
while (brFile.ready()) {
sb.append(brFile.readLine());
sb.append(lineSep);
clob.open(CLOB.MODE_READWRITE);
clob.setString(clob.getLength()+1, sb.toString());
clob.close();
} catch (Exception ex) {
ex.printStackTrace();
return clob;
Ah, just remembered... This will work as a JOB.... >.< ... So the connection aparently is at localhost.
Thanks.

No one? I really need this....

Passing arrays through multiple PL/SQL procedures and functions

I am maintaining a large PL/SQL application. There is a main procedure that is initially called which subsequently passes information to other PL/SQL functions and procedures. In the end an error code and string is passed to PUT_LINE so it can be displayed. What I would like to be able to do is have an array that stores an error code and string for each error that it comes upon during going through each of the procedures and functions. This would involve passing these codes and strings from function to function within the pl/sql application. What would be the best way to implement this and is it possible to pass arrrays or records to other PL/SQL functions? Thanks.

Passing Multiple Values from a worksheet to PL/SQL function.

Hi All,
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
I will try to explain the scenario:
We have a crosstab report that showing all the customer details, deposit sum of a customer in each date in a date range selected. With the customer details we are showing the Rank of a customer based on the deposit in the latest date selected. Filtering is based on the rank, ie Top50 or Top60 etc.( As I said rank is calculating based on the deposit in the latest date).This is working fine.
Now the new requirement is to : For example, in Top50 report, list all the customers, who were in the Top50 list, in any of the dates selected. We are able to display the daywise rank, but when giving a condition like daywiserank <= 50, the result becomes uncertain. Some blank lines, wrong amounts etc..
As a work around we tried to find out the rank in a PL/SQL function. But the issue there is : we have some multiple value parameters used in the worksheet.
Is there any way to pass multiple values selected in a worksheet to a PL/SQL function ?
Or any other work arounds for the scenario explained?
Reagrds,
Jeneesh

Hi Russ,
Thanks for the response.

1. I thought there was an analytical function similar to rank - or maybe an option of rank - that if there are duplicate records to have them all considered the same rank. So if you had 3 records all the same as rank=2 then a condition saying where rank=2 would return the 3 records. You could check into this.
We are already using DENSE_RANK. But the issue is the output contains incorrect null values nd repeated rows.
We got it solved as I explained in the previous post. But will that AGGREGATION MODE setting ( Which discoverer says - not recommended) have any issue? I mean side effects?
Russ Proudman wrote:
2. Another thought is that you can create a PL/SQL routine - that's called from a SQL function registered in Discoverer - where a table is created that does the first part of your query. Then a worksheet is created to use the data from that table. So, in essence, the table would have your top50 ranked customers. Then you can write any kind of worksheet against that table. However, DBAs are loath to allow tables - that they didn't create! - many times in a PROD environment.
Here also the same problem will occur: as the top 50 will depend upon the parameters. I cannot pass those parameters to PL/SQL Function.And storing the top50 ( itmay be top100 or to 150 also) for all combinations of the parameters is impossible
Russ Proudman wrote:
3. Finally, are you sure you're rank function is correct in that if you're getting blank lines, maybe the 'over' part is not considering all columns needed to determine the rank?
Yes the query we are using is correct. The output QUERY of discoverer gives correct results in Sqlplus.

For each row of a table call a pl/sql function

Hi,
i have a search form in adf like this:
parameter1:___
parameter2:____
buttonSearch
Table with results
field1 field2 field3
row1 ------ --------- -------
row2 ------ --------- -------
row3 ------ --------- -------
The user inputs the parameters 1 and 2 then press buttonSearch and the query execute and returns rows 1 to 3.
What i need is for each row call pl/sql function and passed the parameter 1 and 2 and field 1 to 3 (plsql function recives 5 parameters (parameter1, parameter2, field1 , field2 and field3) )
my buttonSearch call a java class that execute ExecuteWithParamters method.
I create the call to my plsql function on Application module class and then export as a java interface.
So i have the function to use in the viewcontroller layer, but i don't know where to use it, and how to pass the paramters: the parameter 1 and 2 that user inputs and the row fields.....
any ideas....
thanks!!

Hi,
for this you need to call the PLSQL function upon table rendering, which means that you need a field in the table referencing a managed bean. In the managed bean you can use #{row} and resolve it using a ValueExpression. #{row} gives you access to the current rendered row (this is why you need to do it when the table renders) and thus allows you to call getAttribute(name) to get the values of field 1 - 3. The search field value you should get through the bindings reference (assuming the search form uses ADF). Then you create an operation binding for the executeWithParameters and call operationBindingName.getParamsMap().put(argname, argvalue); on it.
Frank
Ps.: I am concerned about the performance you get and wonder if it isn't possible to create a transient attribute that executes the function and displays the results. As I understand, the search parameters are only to filter the result set, which you still can do

PL/SQL Function in an infinite Loop, how to destroy?

Hi,
My Apex is using a PL/SQL function and there is an infinite loop. How can I stop it so I can recompile the PL/SQL again? Thanks.

the less obvious is whos session exactly.
I had the same problem - wrong thinking, wrong loop , visible effects of infinitive loop (statistics of the db) . I was trying to kill sessions of the : user , who owns DAD and a user in who's schema runs nasty plsql code - without efect. Kill was confirmed but there was no change. I was made to reboot my server. Probably there is more efective way to do solve this (in my case - I have solved loop-problem after reebot).
Would it be better to kill apache session under OS ? (restart it)
Restart oracle's listner under OS ?
Some ideas ?

Calling Oracle Functions and Procedures in Java

I've looked online for a blurb on using Oracle SQL functions and
procedures in Java, but I haven't found anything. Can someone
either give me a quick crash course on this, or point me to the
best source of information for this?

From the SQLJ FAQ.
http://otn.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#sqljplsql
Within your SQLJ statements, you can use PL/SQL anonymous blocks
and call PL/SQL stored procedures and stored functions, as in the
following examples: Anonymous
block:
#sql {
DECLARE
n NUMBER;
BEGIN
n := 1;
WHILE n <= 100 LOOP
INSERT INTO emp (empno) VALUES(2000 +
n);
n := n + 1;
END LOOP;
END
Stored procedure call (returns the maximum
deadline as an output parameter into an output host expression):
#sql { CALL MAX_DEADLINE(:out maxDeadline) };
Stored function call (returns the maximum
deadline as a function return into a result expression):
#sql maxDeadline = { VALUES(GET_MAX_DEADLINE)
Of course, you can also use JDBC code to achieve the same - the
standard JDBC escape sequences for stored function and procedure
calls are supported, using for example:
"{? = CALL GET_MAX_DEADLINE}"
or:
"{call MAX_DEADLINE(?)}"
and for the rest of the details, get that JDBC crash course...

How do I test sql function in sql*plus?

Hi,
I was given the syntax for a sql function and need to test this in SQL*Plus. What syntax do I use to test this?
p_UserName IN OUT SMUser.Name%type,p_PW IN OUT SMUser.
Password%type) RETURN INTEGER IS
nRet INTEGER :=1;
nCount NUMBER := 0;
BEGIN
select count(*) into nCount from smUser where smUser.Name = p_UserName
and smUser.Password = p_PW;
IF (nCount = 1) THEN
SELECT smUser.Name into p_UserName from smUser where smUser.Name =
p_UserName and smUser.Password = p_PW;
SELECT smUser.Password into p_PW from smUser where smUser.Name =
p_UserName and smUser.Password = p_PW;
RETURN 0;
END IF;
RETURN nRet;
END paulsoraclefunction;
Thanks,
Paul

This should work. You will need to make sure that the variables are declared as the same data type as in the function. Unfortunately, you cannot use %TYPE in declaring SQL*Plus variables.
VARIABLE p_username VARCHAR2(30);
VARIABLE p_pw VARCHAR2(30);
BEGIN
:p_username := 'PAUL';
END;
SELECT paulsoraclefunction(:p_username,:p_pw) FROM dual;
SELECT :p_username,:p_pw FROM dual;

GROUP DATA PL/SQL FUNCTIONS CALLABLE FROM SQL

MAKE GROUP DATA PL/SQL FUNCTIONS (IE. TABLE TYPE PARAM) CALLABLE FROM SQL
Is it possible to create new group function like AVG or to overload them ?
null

Application Developer's Guide (A76939, page 9-60) list a few requirements from user-defined SQL function, and one of them is:
* It must be a row function, not a column (group) function; in other words, it
cannot take an entire column of data as its argument.
But if anyone find a way to do it, please let me know.

Connection per SQL function

I am having problems with transactions when a connection is kept in session (long period of time).
if the user leaves the site, the connection could still be left open until the session expires.
anyone can help me in how to use one connection per SQL function and then returning back to the pool???
Thanks in advance

In your page or function, just open the connection, issue your SQL, and then close the connection.
Closing the connection releases it into the connection pool.
