Passing paramaters in pl\sql code
I declared the following two procedures like this:
In the specs
PROCEDURE applicant_address_update (
p_applicant_term_code IN saradap.saradap_term_code_entry%TYPE,
p_applicant_main_err_code OUT VARCHAR2,
p_ora_err_code OUT NUMBER,
p_ora_err_msg OUT VARCHAR2
In the body
PROCEDURE applicant_address_update (
p_applicant_term_code IN saradap.saradap_term_code_entry%TYPE,
p_applicant_main_err_code OUT VARCHAR2,
p_ora_err_code OUT NUMBER,
p_ora_err_msg OUT VARCHAR2
2) The main procedure
In the SPECS
PROCEDURE applicant_main (
p_applicant_term_code IN saradap.saradap_term_code_entry%TYPE
IN THE BODY
PROCEDURE applicant_main (
p_applicant_term_code IN saradap.saradap_term_code_entry%TYPE
) IS
p_applicant_main_err_code VARCHAR2 (2000);
p_ora_err_code NUMBER;
p_ora_err_msg VARCHAR2 (2000);
When I try to run the procedures I can not pass the parameter, the parameter is frozen
Ex:
This is in toad I would like to give youo a print shot but I can no do here for some reason
I have in the set parameter screen
P_applicant_term_code = I enter 200790
Then I see in the second part of the screen
DECLARE
P_APPLICANT_TERM_CODE VARCHAR2(200);
BEGIN
P_APPLICANT_TERM_CODE := 200690 It is suppose to change to what I enter in the applicant term code 200790
I done this before..I can do it with the other procedures, I have other packages with the same logic
I will appreciate any help with this I am STUCK with this
I will explain this better if I can do a screen shot..Let me know if you are willing to see it and help me with this.
I will send you the print shots my email is [email protected]
Thank you
Are you having an error specifically with TOAD? Can you use SQL*Plus instead?

Is it possible to pass Presentation Variable into SQL code?
Is it possible to create a Prompts that can pass data inputted in the Prompt to a SQL statement?
Example
User inputs
Dashboard Prompt: Date Between today date AND yesterday's date
Which pass information to a measure and labels the the information:
CASE WHEN "Date.Datetable" = {@}DATE1 THEN 'Today' Else 'Yesterday' END FROM "TABLE_Example"You can pass a selected value from prompt to filter a measure or display it as a dynamic label/column header.
To set the label like a dynamic column header:
http://total-bi.com/2011/03/obiee-dynamic-column-headings/
If that is for the measure value then use presentation variable and use them in the formula of the column.
If that is to pass value to the physical layer or bmm layer then use session variable, set it using request variable in prompt and use the session variable in bmm or physical layer view.
Let me know if this helped.

This seems to be your problem, the pipe is wrongly defined. On Windows it looks like

PL/SQL code written in db or in application...????
Hi ,
Which is the best...at performance , maintability... e.t.c.???
To write PL/SQL as validation process of data values going to be inserted in db:
1) as db trigger (before insert or update row-level trigger)
2) in application level - in Forms10g...
This PL/SQL code compares some pairs of data values only.... there DML statement....
Both db server and App server are considered to be or in the same machine or in two machines very close to each other...
Note: i use Db10g .
Thanks...
SimIt is all about moving parts. How many there are. Where they are located.
The less moving parts, the less the complexity, the bugs - and the better the performance (less wheels to turn to crunch data), the easier the maintenance and the better the flexibility.
Part of this is having the moving parts close to the data. Kind of obvious - what is faster? Shipping data from the db engine to a front-end application via a app server and web server? Or shipping the data from the db (SQL) engine to a PL/SQL process running as part and parcel of db instance? IPC is significantly faster than TCP/IP.
Having the moving parts close to the data also means that it can scale with the data. Oracle is good at scalability. It is designed at its very core to be scalable. Partitions to reduce I/O. Shared Server to reduce o/s resource footprint per client session. Shared pool to re-use SQL. DB buffer to cache data. RAC to run multiple db instances for a single physical database. Etc. Etc.
With the application moving parts being close to the data, it inherits this scalability. You can "multi-thread" application code using table pipelines. You have access to forking application code using background processes (DBMS_JOB and DBMS_SCHEDULER). You have bulk processing in order to transfer more data per SQL engine call, between the buffer cache and your application, and thus also reduce expensive context switching.
This list goes on and on.
All this is summarised into the following rules.
Rule 1. Do it in SQL.
Rule 2. Only when SQL cannot do it, use PL/SQL. (e.g. SQL is not suited for managing and controlling process flow - PL/SQL is)
Rule 3. Only when PL/SQL cannot do it, use <insert-language-here> (e.g. PL/SQL cannot render a Windows grid on the client - but Delphi/C#//Java can).
Also keep in mind that in the modern client-server paradigm we deal with a web architecture. Which means the client is a web browser. And this means that PL/SQL can pass the data (HTML) required by the client (web browser) to render the User Interface.
Have a look at APEX (Oracle's Application Express) for how this works. http://apex.oracle.com
All you need to develop web applications is APEX (a PL/SQL product suite in the database) and a web browser. Kickass stuff... :-) -
Dbms_session.set_sql_trace(true) in PL/SQL Code to trace execution
Hi,
I'm working on some legacy PL/SQL Code with the objective of tuning. I added the following to the PL/SQL Body so that I can trace the execution and identify low-hanging-fruit that can be tuned.
I added the following after the BEGIN section of the PL/SQL body:
trace_process_flow_info_sp( this procedure captures the parameters passed into the procedure of the package body);
execute immediate 'alter session set events '||''''||'10046 trace name context forever, level 12'||'''';
dbms_session.set_sql_trace(true);
My objective is to capture the execution of the code, capture the bind variable values, however I am not seeing the bind values in either tkprof or the Trace Analyzer.
Any Ideas on how to see the Bind Variable Values?
ThanksLevel 0 means no binds.Are you sure that this level is available?
According to note 115675.1 there are only four
possible levels (1,4,8,12)Hmmm it seems you are right.
SQL> conn xxx/xxx@xxx
Connected.
SQL> ed
Wrote file afiedt.buf
1* alter session set events '10046 trace name context forever, level 0'
SQL> /
ERROR:
ORA-02194: event specification syntax error 231 (minor error 283) near '0'
SQL> ed
Wrote file afiedt.buf
1* alter session set events '10046 trace name context forever, level 1'
SQL> /
Session altered.
SQL> The same results for 9.2.0.7.0 and 10.2.0.1.0
So OK a correction dbms_session.set_sql_trace(true) means level 1, but anyway it means no binds.
Thank you for your correction, should go and update my article!

Accessing html field value from pl/sql code, in the same package
hi friends,
my pl/sql web application is working fine. but now i need a small requirment.
ie, basicaly i need to access the user entered value of an element in html based form from pl/sql code, which is developed using pl/sql toolkit.
Here is the scenario:-
User entered a value in field1, then navigate to field2, and click a button for list of values,
when he clicks the button, internaly it is opening a cursor, where i want to pass field1's value to my cursor as a parameter. So in my pls/sql code , i want to access the value of field1. If you know, please help.
see the snippet of code.
htp.p('
function f1()
if (parseInt(learnIdx) ==1 )
for i in dev_Need('1')/*here i want to pass html form element value as a parameter */
loop
htp.p('content += "<option value='''||a.version_name||'''>'||a.version_name
||'</option>''"; ');
end loop;
thanks in advance.
Zameer.N.AHi,
Here's my suggestion
If you wanna access the dll check out "external procedures", you can search it everywhere in OTN.
However it's easier to use Heterogenous Services to connect database with other sources.

Execute all SQL code as individual Oracle user, not APEX_PUBLIC_USER
Is it possible to get APEX to execute SQL code as the user's existing Oracle database user instead of APEX_PUBLIC_USER?
Besides having all of the security already defined for each of the existing users at the database level, the existing application also handles generating audit trails with triggers that pull the username executing the SQL instead of accepting passed values. At the moment APEX_PUBLIC_USER is plastered everywhere as the user that generated the changes.rcy_evdriver wrote:

Why are you asking this? +"At the moment APEX_PUBLIC_USER is plastered everywhere as the user that generated the changes"+ indicates that it might be a bit late to be making fundamental discoveries about APEX and database security? -
How to create dynamic HTML page using PL/SQL code in APEX.
hello,
I am woking on one APEX application in which i want to create one dynamic HTML page on button press using PL/SQL code.
ThanksIt is possible to create HTML page with dynamic content. One way would be creating hidden field (e.g. P1_HTML on page 1) with dynamic HTML and on button click you redirect to page 2 and pass P1_HTML item value to item P2_HTML on page 2. On page you must have PL/SQL region. You can then render your dynamic HTML with code:
htp.p(:P2_HTML);
Don use APEX URL for passing HTML value. Problem and solution is described here: http://blog.trent-schafer.com/2011/04/03/dont-pass-string-parameters-in-the-url-in-apex-its-a-bad-idea/

Script fails when passing values from pl/sql to unix variable
Dear All,
I am Automating STATSPACK reporting by modifying the sprepins.sql script.
Using DBMS_JOB I take the snap of the database and at the end of the day the cron job creates the statspack report and emails it to me.
I am storing the snapshot ids in the database and when running the report picking up the recent ids(begin snap and end snap).
From the sprepins.sql script
variable bid number;
variable eid number;
begin
select begin_snap into :bid from db_snap;
select end_snap into :eid from db_snap;
end;
This fails with the following error:
DB Name DB Id Instance Inst Num Release Cluster Host
RDMDEVL 3576140228 RDMDEVL 1 9.2.0.4.0 NO ibm-rdm

But when I change the select statements below the report runs successfully.
variable bid number;
variable eid number;
begin
select '46' into :bid from db_snap;
select '47' into :eid from db_snap;
end;
Even changing the select statements to:
select TO_CHAR(begin_snap) into :bid from db_snap;
select TO_CHAR(end_snap) into :eid from db_snap;
Does not help.
Please Help.

NischalHi,
could it be the begin_ and end_ Colums of your query?
Seems SQL*PLUS hs parsing problems?
try to fetch another column from that table
and see if the error raises again.

You're missing the final quote - you have the quotes for SCOTT but not the one to close the SQ string:

How to 100% Protect PL/SQL Code By Wrapped in Oracle Database 10g R2
Hello,
Is Possible to 100% Protect PL/SQL Code By Wrapped in Oracle 10g R2 ?
If it is not possible by wrap in oracle 10g R2,
Please, let me suggest, how i will be able to 100% protect PL/SQL code in Oracle Database 10g R2.
Because, I have lot of functions, procedures & package's in my project.
Which is running in field filed.
So, i have needed to protect 100%.
Also, will i convert to al functions, procedures & package's to .pll file ?
And .pll file to .plx file?
Is it possible to convert .plx file to .pll file ?
Please, let know any better solutions in this case....
Regards
MehediHello,
No, wrapping is not a 100% secure method. It could prevent your code from amateurs, but not from professional hackers. Look at the article http://docs.oracle.com/cd/B28359_01/appdev.111/b28370/wrap.htm#BEHGBJAA
It says: "•Wrapping is not a secure method for hiding passwords or table names.
Wrapping a PL/SQL unit prevents most users from examining the source code, but might not stop all of them."

How to reference LEVEL in a TREE's SQL code
Is it possible to somehow reference LEVEL in a tree's sql code so that you can use a decode statement to selectively create links on specific levels only i.e. NOT on the root level?
e.g.
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( LEVEL, 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
null a1,
null a2
from TREETABLE
order by name
one solution I've implemented is to create a DB function e.g.
create or replace function get_tree_level(v_child_id number) return number
is
v_level number(2);
begin
select level
into v_level
from TREETABLE
where child_id=v_child_id
start with child_id=1
connect by prior child_id= parent_id;
return v_level;
end;
and then use
decode( get_tree_level(child_id) 1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || '::::P43_CHILD_ID:' || CHILD_ID) link,
but this is too slow as I have quite a few records in the tree and takes too long to render
regards
Paul POK I found a workaround after reading
How to add URL to tree
The view my tree is build on is constructed out of 3 unions and 4 "selects" ( the first select creates the ROOT NODE where "1" is also used as a hard coded foreign key (Parent_id), in the company table.)
I just added a new column called tree_level to the query which is hard coded wrt its level on the hierarchy.
e.g.
CREATE OR REPLACE FORCE VIEW COMCONSTUTREE ("CHILD_ID", "PARENT_ID", "NAME","TREE_LEVEL") AS
select 1 as child_id,to_number(null) as parent_id ,'Company' as name,*1 as tree_level* from dual
UNION
select COM_ID, 1, COM_NAME,2
from company
UNION
select CON_ID,CON_COMPANY_ID, substr(con_name,instr(con_name,' ')+1) ||', '||substr(con_name,1,instr(con_name,' ')-1),3
from contact
UNION
select STU_ID,STU_CONTACT_ID, STU_LAST_NAME||', '||STU_FIRST_NAME ,4
from student;
the tree code now becomes
select "CHILD_ID" id,
"PARENT_ID" pid,
"NAME" name,
decode( tree_level,1, null,'f?p=' || :APP_ID || ':43:' || :APP_SESSION || ':TREE:::P43_CHILD_ID:' ||CHILD_ID) link,
null a1,
null a2
from COMCONSTUTREE"
order by name -
Passing item to pl/sql to modify the query
hi all,
i am new to apex and appreciate any help :)
what i am trying to do do is show point of interest on the map, and filter them :)
what i already have done:
i have a page.1 where is a list and when you click the link it sent you to page.2 with 3 items, "type" start date "end date"
type is well the type of point :)
start date and end date are today's dates that are pulled from db when clicked
when page.2 opens i can see the 3 items on the page
the page body loads a pl/sql procedure which:
pl/sql code on page.2
"begin item_locations; end;"
queries the database and returns the
"type" "lat,long" "date" "id"values from different tables
example;
id type lat,long date
coffe 2 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
tea 2 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
food 2 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
cars 1 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
bars 3 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
shops 6 40.386289,49.824348 5 07-OCT-12 10.37.54.000000 PM
then the procedure takes outputs as "htp.print" and creates a map and show ALL the points,
i want to do 2 things
1) i want to filter whats shown on the page by type and date when the page loads (assuming user coming from page.1 with the items full :) )
my idea is to add "where type=**type from page.2 item** and date **page item date1** between **page item date2**
2) add a button so and if i manually input/modifiy the page items on page2. them click the button will have new results :)
by setup:

thanks in advancceSounds like an interesting application!
The easiest way to do this would be to change your procedure item_locations to include the three parameters you want to use, so that your procedure looks like:
PROCEDURE item_locations
(p_type VARCHAR2 DEFAULT NULL
,p_start_date DATE DEFAULT NULL
,p_end_date DATE DEFAULT NULL)
IS ...
BEGIN
Select col1, col2, col3
from my_table
where type = NVL(p_type,type)
and my_date between NVL(p_start_date,my_date) and NVL(p_end_date,my_date)
htp.p(my_data)
END item_locations;
etc
-- Note - this is purely example code and not intended to compile as is. Just saying.Then in your apex page process, you simply call
BEGIN
item_locations (:P2_ITEM, :P2_START_DATE, :P2_END_DATE);
END;I hope this makes sense. It sounds like you're so new that you have not had the pleasure of doing the 2 Day Developer Guide. I would strongly recommend you do this if you are not familiar with Apex - it is a necessity.
Kind Regards, Pete
