HTML in PL/SQL block

How to add "Welcome" using HTML in the following PL/SQL block. I want to add the Welcome user message when user login in to the Apex application.
BEGIN
HTP.prn(get_app_user);
END;Sanjay

Got the solution. Modified the PL/SQL block as follows :
BEGIN
htp.print('<p>Welcome');
HTP.prn(get_app_user);
htp.print(' to My application.<p>');
END;

Resolved: Use value from select list in pl/sql block

Hello,
I have a form with a select list: P18_BONUSTYPE, the values of which come from a LOV.
When the user clicks a button, a page process is used to insert a row into a table.
When I use the :P18_BONUSTYPE bind variable in my insert statement I get an error "Invalid number" I get an "Invalid number" error. I assume that APEX is using the displayed text in that bind variable, not its actual (html option) value.
I checked the HTML of the page, and the correct values are in the select list.
Can someone tell me how to get the value into a bind variable that can be used in a pl/sql block for a page process?
Thanks

Issue was a value in another item.

Did you tried changing the value using "to_number"? (i.e. to_number(:P18_BONUSTYPE)).

Using item values in a pl/sql block or sql query in a process

Hi,
I am new to apex. Developing my first application.
I have created a form with 2 items. Based on the values in these items, when I click a button, want to execute a
query.
eg: emp_name(item1), deptno(item2). When I clock on find button, I want to fetch the record and disply the resultant
columns in other created items like sal,comm etc.
How can I do this?
I tried the following pl/sql block in a process
begin
select sal,comm into p1_sal,p1_comm from emp where name=p1_name and deptno=deptno;
end;
But it is not accepting the page items in the block.
How to achieve this?
Thanks,
Kavitha

Item data using PL/SQL block region

hello community,
I have searched the whole forum using Pl/SQL but couldn't find an answer for this.
I have a PL/SQL Anonymous block region, containing database items fetched by a process and custom items getting set by the Pl/SQL source.
based on the ID I am getting the records i.e.
Region Source (PL/SQL Anonymous block)
declare
CURSOR cpc_cur is SELECT "PRODUCT", "APPCODE", "COMCODE", "DESCRIPTION" from cp2 where "ID" = :P4_ID;
begin
for cpc_rec in cpc_cur
loop
:P4_P_NAME := cpc_rec.product;
end loop;
end;
The custom item is text field with source Item.
The item value is not filled in for the first time after login, but it shows the value in the session state as with status 'I', but from then onwards it works fine.
Why is the value not fetched the first time?
even I tried the postcalculation using nvl and it sets it to null.
Also set_session state doesn't work.
If I make the custom Item as Pl/SQL function, and write the query then it works fine, but gives problem as while inserting a new record the query has no ID to refer.
Thanks in advance.
Piyush

Thanks Scott!!
1) I am using PL/SQL region to get the data for few items on the form region which is based on a table, all table attributes are database items and additional Items whose data I am fetching from the PL/SQL are Custom items.
2) Yes the loop executes only once per page view, Is their a better query?
3) Well its very dumb to have a item source as item pointing to itself, but since the values are in session with status 'I' I thought this could do the trick!
4) As the item source type used is [only..], the first time user logs in it doesn't displays the value, need to refresh the page, but the second time its gets the values form the session.
5) If I make the Item source as PL/SQL function, I just fetch the records individually, same as in the query which works fine, but the items are also used for insertion (add new) and I clear the cache, so it gives error as it cannot execute the pl/sql function(no ID while addition)
I hope I have answered your questions! If you have patience you can read the detail description.
test application on oracle server
http://apex.oracle.com/pls/otn/f?p=24296:1:3544773135949858:::::
login/password test/test
Application name :Test
The page has 2 regions. when clicking on SN the values are transfered to form, except for 'Appcode'.
Detail Description:
I have a page with 2 regions.
One region is a report region showing fewer details from a view. The other region is a PL/SQL(form region), which shows all the details and is linked to the report region.
While linking I pass the ID from report and autofetch the data in form region.
But some Items are not related to that database, so I created few items on form region (Custom Items). To fill in these values I did these things.
1) Pass them through script (but passing 7 parameters through script is not good)
2) Made another autofetch process to fetch the remaining Items, but it seems that its not possible to have 2 autofetch process on one form region.
3) Changed the form type from HTML to PL/SQL, to assign the custom items values through code.
for cpc_rec in cpc_cur
loop
:P_custom_item := cpc_rec.data;
end loop;
Either make source type static or Item (the same item P_custom_item).
This pl/sql code do assign them the values, In the session state their status is 'I', but are not displayed on the page for the first login, need to refresh the page, as the source used is (only when..) it gets the value the second time.
4) Made the item source as PL/SQL function and assign them the value. It works fine, but the same item is also used displaying description while insertion(gives error while insertion), so made a conditional process, even that gives the same error.
I have a questions.
If an Item status is 'I' in the session state, why is it not displaying the value on page.
Thanking you in anticipation

Debugging PL/SQL blocks in SQL Developer

Is there any way to debug blocks of PL/SQL in SQL Developer by setting breakpoints in the code? I'm using SQL Developer.
I'm trying to debug some fairly complex PL/SQL blocks - they are not procedures or functions and so I'm unable to run them in debug mode.
p.s. Apologies should have posted this in the database forum really.

DDL inside PL/SQL Block

Is there anyone knows if DDL statement can be include inside the PL/SQL block?
I mean, creating a table, doing DML in that table and then dropping it? I have to do this because I'm having integrity constraint errors (ORA-02291) in the tables I will use.
I need to
update table_1 set id = 2 where id = 1
but it it found child records in table_2.
when i tried:
update table_2 set id = 2 where id = 1
Of course I cannot as well update table_2 because it will not found parent record in table_1, as it had an error earlier and there were more records in table_1 than table_2.
table_1 records = 374 rows
table_2 records = 38 rows
I did some strange logic below:
a. Creating a temporary table,
b. inserting there records in table_1,
c. updating the temp table,
d. delete the records i got in table_1,
e. update table_2 (can now do an update since no child records in table_1 will be found after the delete),
f. insert records from temp table to table_1
g. drop the temp table.
BUT, I cannot create, manipulate, and drop that temp table inside the PL/SQL table.
Any thoughts.
Thanks in advance!

Another scenario is to create your constraints as deferred. I'v recently blogged about another deferred constraint usage here
http://gplivna.blogspot.com/2007/05/deferred-constraint-real-life-scenario.html
but your case also is appropriate.
But the ultimate problem BTW is that you need to update your PK values and that's at least very questionable (ok to my mind bad) design.

Display an Alert message in PL/SQL block in APEX

Hi,
we are getting an oracle exception while inserting a new row. As it is having the unique constaint on a coulumn.
Now the problem iis we need to Display an "Alert message" based on the input field validation. That java script code for alert has to be embeded nside a PL/SQL block in Oracle APEX Application.
we tried doing this with below code:
Begin
INSERT INTO <<table name>>(ID,NAME) VALUES (s1,:TXT_s2);
exception when others then
htp.p('<script language="javascript">');
htp.p('alert("Exception");');
htp.p('</script>');
end;
If anybody knows .... please reply.

If your end goal is showing a pretty error message instead of the message that the tables unique constraint raises try the following. This logic will show a nice message and not try to insert non-unique data.
(1) Create a validation of type "Function Returning Error Text".
(2) Place similar code like the following in your validation. Notice that if the unique name does not exist the no_data_found returns null allowing the validation to pass.
DECLARE
v_error varchar2(100);
BEGIN
SELECT 'A person by this name already exists.'
INTO v_error
FROM your_table
WHERE your_name = :P1_YOUR_NAME;
RETURN v_error;
EXCEPTION
WHEN no_data_found THEN
RETURN NULL;
END;

Performance: Operations in Cursor vs. Operations in PL/SQL block

Why does I have a better performance when I program operations in complex cursors instead of programming the same statement in a pl/sql block in a stored procedure?
Operation in a Cursor:
CURSOR c IS
DECODE(name,'Peter','dog','cat') animal
...The same Operation in a PL/SQL block:
begin
if name = 'Peter'
then
animal = 'dog';
else
animal = 'cat';
end if;
end;
...I know that a parsed cursor is placed in the Shared Pool and reference
a context area in the PGA.
Does anybody have an idea?

Maybe because if you can write only a SQL query, it is faster than to write PL/SQL code that will do the same job. See following thread for a analog discussion: Re: pl/sql table

How to test for différent Select into a single PL/SQL block ?

Hi,
I am relatively new to PL/SQL and I am trying to do multiple selects int a single PL/SQL block. I am confronted to the fact that if a single select returns no data, I have to go to the WHEN DATA_NOT_FOUND exception.
Or, I would like to test for different selects.
In an authentification script, I am searching in a table for a USER ID (USERID) and an application ID, to check if a user is registered under this USERID for this APPLICATION.
There are different possibilities : 4 possibilities :
- USERID Existing or not Existing and
- Aplication ID found or not found for this particular USERID.
I would like to test for thes 4 possibilities to get the status of this partiular user regardin this application.
The problem is that if one select returns no row, I go to the exception data not found.
In the example below you see that if no row returned, go to the exception
DECLARE
P_USERID VARCHAR2(400) DEFAULT NULL;
P_APPLICATION_ID NUMBER DEFAULT NULL;
P_REGISTERED VARCHAR2(400) DEFAULT NULL;
BEGIN
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID AND APPLICATION_ID = :APP_ID ;
:P39_TYPE_UTILISATEUR := 'USER_REGISTERED';
EXCEPTION
WHEN NO_DATA_FOUND THEN
:P39_TYPE_UTILISATEUR := 'USER_NOT_FOUND';
END;I would like to do first this statement :
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID Then to do this one if the user is found :
SELECT DISTINCT(USERID) INTO P_USERID FROM ACL_EMPLOYEES
WHERE USERID = :P39_USERID AND APPLICATION_ID = :APP_ID ;etc...
I basically don't want to go to the not found exception before having tested the 4 possibilities.
Do you have a suggestion ?
Thank you for your kind help !
Christian

Surely there are only 3 conditions to check?
1. The user exists and has that app
2. The user exists and doesn't have that app
3. The user doesn't exist
You could do this in one sql statement like:
with mimic_data_table as (select 1 userid, 1 appid from dual union all
                          select 1 userid, 2 appid from dual union all
                          select 2 userid, 1 appid from dual),
-- end of mimicking your table
         params_table as (select :p_userid userid, :p_appid appid from dual)
select pt.userid,
       pt.appid,
       decode(min(case when dt.userid = pt.userid and dt.appid = pt.appid then 1
                       when dt.userid = pt.userid then 2
                       else 3
                  end), 1, 'User and app exist',
                        2, 'User exists but not for this app',
                        3, 'User doesn''t exist') user_app_check
from   mimic_data_table dt,
       params_table pt
where pt.userid = dt.userid (+)
group by pt.userid, pt.appid;
:p_userid = 1
:p_appid = 2
    USERID      APPID USER_APP_CHECK
         1          2 User and app exist
:p_userid = 1
:p_appid = 3
    USERID      APPID USER_APP_CHECK
         1          3 User exists but not for this app
:p_userid = 3
:p_appid = 2
    USERID      APPID USER_APP_CHECK
         3          2 User doesn't exist
