Body of function from PL/SQL query SQL - problem with where Cluase return

Hi all
I have problem with sub PL/SQL. Where clause does not filter the values even when I change the value: P7_INVESTIGATOR. I have marked with an asterisk for where clause where I want the values to filtered.

DECLARE
v_sql varchar2 (5000);
v_inv VARCHAR2 (100);

Start
v_inv: = UPPER(:P7_INVESTIGATOR);

v_sql: = ' select TBLCASES. INVESTIGATOR as an INVESTIGATOR,';
v_sql: = v_sql | "TBLCASES. CASENUMBER as CASENUMBER,';
v_sql: = v_sql | "TBLCASES. OPENDATE as OPENDATE,';
v_sql: = v_sql | "TBLCASES. ESTCOMPLETE as DATE_CIBLE,';
v_sql: = v_sql | "TBLCASES. STATUS of STATUS ';
v_sql: = v_sql | "TBLCASES. Case CODE case CODE as,';
v_sql: = V_sql | "TBLCASES. FAIR_HOTLINE as FAIRHotline,';
v_sql: = v_sql | "TBLCASES. NYSIG as NYSIGCase,';
v_sql: = v_sql | "TBLCASES. The REGION';
v_sql: = v_sql | "TBLCASES. PROGAREA as PROGArea ';
v_sql: = v_sql | ' from TBLCASES where 1 = 1';
**************************************************************
If v_inv <>null then
v_sql
: = v_sql | "and UPPER (trim (tblcases.investigator)) = UPPER (trim (v_inv))';
END IF;
***************************************************************
v_sql: = v_sql | "order by tblcases.investigator";
Return v_sql;
end;

Thank you

Or it is possible to write it this way:

v_sql := v_sql ||'  and UPPER(trim(tblcases.investigator)) = UPPER(trim(:P7_INVESTIGATOR))';

In this case we will use bind variables and we all know that it is very important.

Of cause, it is the best option. and I strongly suggest the OP to use.
But it depends on how the sql is used later.
Without knowing that, we cannot be sure if the item is available here.

I can't see a message from my Union because of problems with the address changed for pop-upwindows and some other issues

Hello
I am from Sweden and I have problems with a Web site that has my Union. I could see messages from them before, but they changed their address and on the site, they say people that they must put the new address on the approved list of the pop-up windows. I did but it still does not. Maybe I did wrong, I don't know, but it's annoying as hell that I can't see the messages they send.

I really need help with that.

How to the return type of function from PL/SQL
Hello

I need to create a function that returns a list of ID, which is stored in a type T_IDs, something like:

search function (searchstring in varchar2) return to T_IDs

I have a little problem with the type within the body of the function using a select statement and filling

Select the id of the table where the text as searchstring.

which is to select a list of IDS corresponding to the where clause. Is it possible to use select in or should I go for another mechanism?

Thanks for all the ideas.
Bulk Collect works for me...
```
SQL> create type t_ids as table of number;
  2  /

Type created.

SQL> ed
Wrote file afiedt.buf

  1  create or replace function get_ids(deptno in number) return t_ids is
  2    ids t_ids;
  3  begin
  4    select empno
  5    bulk collect into ids
  6    from   emp
  7    where  deptno = get_ids.deptno;
  8    return ids;
  9* end;

However, I would rarely use such a data collection, as it fills with PGA in memory and passing a lot of data between SQL and PL/SQL. I must have a just cause and justified in wanting to do things this way.

Irregular data loss - function from PL/SQL returning data using Ref Cursor
Database Version: 10.2.0.4.0 (node 2 CARS)

The high-level process flow is as below:
(1) insert records in a few tables & commit the same
(2) call the pl/sql function to extract files (on certain conditions with joins with other tables) of the tables which are filled in step 1.
-> It uses the ORDER BY clause to queries inline & line number 5000 records return for each call.
Sense - if inline query is supposed to return 1,00,000 records then 20 calls to the same function. This, because the application cannot contain records beyond number.
(3) the data returned by the ref cursor is then processed by application (Tibco BW) to generate the flat file.

We are facing the problem of data loss in the file and there is no fixed model. It happens once between 200-300 calls process.
Resolution: When the problem occurs, triggering the process and in almost every time re-outbreak of the process provides required data.

Guidance on what could be the reason?

Your SELECT statement is almost certainly incorrect
```
SELECT *
  FROM ( SELECT A.HIERARCHY_KEY, B.KEY, B.VAL_KEY, A.KEY_NEW, C.ITEMID, B.VAL_TAG, B.sort_order,ROWNUM ROWNUMBER
           FROM AOD_HRCH_ITEM A, AOD_HRCH_ATTR B, AOD_HRCH_ITEMS C
          WHERE A.outputid = B.outputid
            AND A.outputid = C.outputid AND A.outputkey = B.outputkey
            AND A.outputkey = C.outputkey AND A.outputid = outinstrid
            AND A.outputkey = outinstrkey AND A.ITEM_SEQ = B.ITEM_SEQ
            AND A.ITEM_SEQ = C.ITEM_SEQ AND A.HIERARCHY_LEVEL_ORDER = B.SORT_ORDER
          ORDER BY A.HIERARCHY_LEVEL_ORDER DESC)
 WHERE ROWNUMBER < rownumbereend
   AND ROWNUMBER >= rownumberstart;
```
Since the ORDER BY is applied after the ROWNUM is assigned in this case, your query is requested for a period of 5000 lines any arbitrariness. It would be perfectly valid for a single line to return in each of your 200 different calls or for a line to return in any of them.

You definitely want to do something in the sense of the canonical askTom wire
```
select *
  from ( select a.*, rownum rnum
           from ( YOUR_QUERY_GOES_HERE -- including the order by ) a
          where rownum <= MAX_ROWS )
 where rnum >= MIN_ROWS
```
That said, it seems inconceivable that Tibco is unable to manage a cursor that returns more than a certain number of lines. You do a ton of work to return the data pages that are certainly not necessary. Unless you're saying that you somehow paralyzed your installation of Tibco giving him a ridiculously small amount of memory to process, something doesn't look good. A slider is just a pointer - it holds that no data - so the number of lines that you can extract a slider should have no impact on the amount of memory on the client application needs.

As others have already pointed out, your exception handler is almost certainly do more harm than good. Return the error codes and error messages as from the OUT parameters, instead of simply allowing the exception to propagate deletes a ton of useful information (such as the mistake of the stack) and makes your process much less robust.

How can I get a value from a function from pl/sql by OADBTransaction
Hi all
Hope you will be fine.
as we know, we can get a sequence by this code value:
Super.Create (AttributeList);
Transaction OADBTransaction = getOADBTransaction();

Vendor ID is obtained from the table sequence
Number supplierId = transaction.getSequenceValue ("FWK_TBX_SUPPLIERS_S");

My question is how can I get a value in a variable to a pl/sql function:
the function is defined as follows:
******
create or replace function getNextTrans return varchar2
is
Team varchar2 (20);
Start
SELECT "CASH". TO_CHAR (SYSDATE, 'DDMMYYYY') | GP_CASH_TRX_SEQ. NEXTVAL FROM DUAL;
return team;

Authorisation scheme: poll from function from PL/SQL Boolean value
Hello
I use with authorisation schemes on page 2 as function of PL/SQL to return a Boolean.

The value of P1_PREF is from page1 (search) report box, driven model type (< class td = "t12data" >#PREF # < table >)

--(lien hypertexte pref) to page 2 P2_PREF.

I tried passing the value (: P2_PREF or: P1_PREF) but it does not work. If I assign (where pref = "100") or any other value it works fine.
Is it to do with sessions or to store the value in a variable prior to authorization of the page. Please notify.

DECLARE
v_userrole VARCHAR2 (400) DEFAULT NULL;
v_staffaccess VARCHAR2 (400) DEFAULT NULL;
BEGIN

Select USER_ROLE IN v_userrole
to userrole
where (upper (USER_LOGIN) = upper(:APP_USER)
or (upper (:APP_USER)) = 'TEST');

Select staff_access in the v_staffaccess of sm
where pref = "P2_PREF";

IF INSTR (v_userrole, 'A') > 0
THEN
RETURN TRUE;
END IF;

IF (((v_userrole) = "SP" OR (v_userrole) = 'U') and nvl (upper (v_staffaccess), 'x') do not ("SUPER %')) THEN)
RETURN TRUE;
ELSE RETURN FALSE;
END IF;

END;

Please advise on the passage of the value.
Thank you very much
Harinder
Hi Harinder

There are many ways this can be achieved. It seems to me that your problem is that the value passed to page 2 is not be updated at each visit?

So how about this (as only one way to do it).

Page 1 to P1_PREF
You press a button or link to go to page 2, that SUPPORTS THE PAGE (important)
You have a hidden item P2_PREF on page2, who has...

Source used - always replace any existing value in session state
Source - point Type

And then refer to P1_PREF.

Or you can create a calculation that sets the value of P2_PREF to the value of P2_PREF on the laundry front header.

Or your button on page 1 could create a branch to page 2 using "defined these elements" "with these values" options in the industry...

How to operate my function from PL/SQL?
I have 4 table

1st is EMPLOYEE (E #, ENAME), the primary key is E #.

2nd is DRIVER(E#,L#), the primary key is E # ID EMPLOYEE

3. is TRIP(T#,L#), the primary key is T #, foreign key L # driver

4th is the primary key TRIPPT(T#,PT#) T # travel

I create a function that finds the length (total number of pt #) of the longest point to the driver
```
create or replace function LONGPT (DL# in TRIP.L#%type)
   return TRIPPT.PT#%type
IS
   TRIPPT#   TRIPPT.PT#%type;
begin
   select max (PT#)
     into TRIPPT# 
     from TRIPPT
    where T# in (select T#
                   from TRIP
                  where L# = DL#);

   return nvl (TRIPPT#, 0);
end LONGPT;
/ 
```
How can I do a select query to view the employee NAME, LONGPT. The name of the driver that perform no trigger point must be in the application as well.

I try
```
 
SELECT DRIVER.L# AS License_No, LONGTPT(TRIP.L#) AS "LONGEST POINT" 
FROM DRIVER 
   LEFT OUTER JOIN TRIP on DRIVER.L# = TRIP.L#;
This only query the L# and the LONGEST Point.
```
Could someone guide me how to do select on screen the ENAME and with my LONGPT function.

I don't know what you mean by "the employee, LONGPT.

My best guess is that you need join the employee table in your current query:
```
SELECT  driver.l#          AS License_No
,     employee.ename                              -- *****  NEW  *****
,     longtpt (trip.l#)      AS "LONGEST POINT"
FROM           driver
JOIN          employee     ON   driver.e#     = employee.e#     -- *****  NEW  *****
LEFT OUTER JOIN trip          ON   driver.l#     = trip.l#
;
```
Again, this is just a guess and guess isn't always the best way to solve problems.

I hope that answers your question.
If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and the results desired from these data.
Explain, using specific examples, how you get these results from these data.
Always say what version of Oracle you are using (for example, 11.2.0.2.0).

IPSEC VPN from Site to Site - NAT problem with address management

Hi all

I have two Cisco ASA 5505 performing of IPSEC Site to Site VPN. All traffic inside each firewall through the VPN tunnel and I have full connectivity. From site A, I can connect to the inside address of the ASA at the site B and launch of the ASDM or SSH, etc.

- If I can make the ASA Site B to use inside interface as its address management (I already have management access to the inside Interface)
- I have NAT can address external interfaces to Site B before moving through the VPN tunnel management traffic so that it appears to come from Site B inside the address
- I can NAT VPN traffic as it appears in the Site A for management traffic to Site B on the right address.
The problem is that my PRACTICE Please also come from this address and I need the application before being on an internal address to even if my CA.

Thanks for any help.

Thanks, I understand what you are trying to achieve now.

However, I think that I don't have good news for you. Unfortunately PEIE request can be initiated of the SAA within the interface, as there is no option to start the query from the inside interface. With other features of management such as AAA, logging, you have an option to specify what ASA desired originally to demand from interface, but CEP doesn't have this option.

Here's how you can configure under the trustpoint crypto, but unfortunately by specifying the interface doesn't not part of option:

In general, I put each ESXi host to synchronize time with a domain controller. You'll want to start and stop with the host country, but you will first need to set some time synchronization servers in the options. You can choose dns names or IP addresses.

3.) associated with #2, I would add the NTP source in Options?

Yes, you must add an NTP source before you can activate start/stop with the host.

Once you choose to synchronize time with a domain controller, I'll make sure that your domain controllers are the synchronization of time with another source of time. You can find time servers NTP free on internet, I usually go with one of them. Microsoft has one that you can use as well.

Assigning a page element in the region of the "body of function return PLSQL SQL query.
I've not been here in a long time. I like the new forum text editor!

I have a search page in my application that contains a return region of query SQL PLSQL function body. I use PLSQL to build a query based on the user entries in various page numbers (search text, serial number, year, etc.). Using PLSQL is very useful to enforce the page quickly because there are 1/2 million lines with a lot of text fields some of which are CLOB.

Users want to know how many rows were returned, but if I allow using a paging system that includes the total performance dies because ApEx has to sort through all the pages of output. Instead, I use ' line varies X to Y "without the part of" Z", and it's pretty fast. I can't use the #TOTAL_ROWS # because it does not work with this system of pagination.

So, I built a code within the region of function body PLSQL to build a second query that counts only the lines based on the input parameters. I can do this query within the region using EXECUTE IMMEDIATE and the number to an output variable. The disconnect is that I can not then assign it to a page element. If I add a statement assigned to a page element, either by

: P45_COUNT: = p_count;
or
APEX_UTIL. SET_SESSION_STATE ('P45_COUNT', p_count);

then when I submit the changes I get

ERR-1002 unable to find point item ID 'P45_COUNT' in the application '4000 '.

as if the ApEx is not looking for the item in my application, but in the application development environment. I am able to write the results to a table and then recover data in the next region. That's how I got around the problem, but it seems too complicated and unnecessary.

I wrote the following code just to illustrate the problem.

Make sense? Any ideas?

Thank you!
