Help on Cursors
Hi,
I am having the following cursor, which returns 10000 rows.
Cursor c1 is
select * from emp;
I have the following query on the above cursor.
1) Is there any way by which I can directly go to the 1000th row.
2) Since the above cursor has an Emp_Name column, is there any way by which I can directly go to the row having an Emp_Name='Whatever'.
Thanking you in advance for your kind help.
MAK
for the second point you can simple add the where condition in the cursor query, like:
CURSOR c1 IS
SELECT * FROM emp WHERE emp_name = 'Whatever';
if your value is static you can do it this way, else you can write a parameterized cursor as follows:
CURSOR c1(pEmpName VARCHAR2) IS
SELECT * FROM emp WHERE emp_name = pEmpName;
and then open the cursor like this:
OPEN c1('Whatever');
for the first point, going directly to 1000th row, as far as i know, you have to navigate thru the loop.

Need help with cursor selection in control panels
I can't get my cursor to work in the control panel at the top of the screen, for example, when I select text and want to change the font size, etc. It won't even select to change from font to paragraph mode. Other issues are trying to choose the selection tool, which I can only do with the "V" shortcut tool--escape doesn't work, nor does the cursor choose the icons. Help!

Help please - Cursor not working whilst browsing internet
Hi
Not long had my Curve 8520 and afraid I'm a bit of a techno dinosaur so please bear with me ! Wonder if someone can help with this.
Whilst browsing the internet my "cursor" has suddenly stopped working. My "cursor" - the little black arrow - is still there but when hover over a search box for example and "click" my trackball nothing happens, similarly if the little hand symbol appears on a link if I "click" the trackball nothing happens. I've discovered I can press return when the hand appears and it goes to the link, but this is no use when only the arrow appears.
Any help greatfully received
Ken
Solved!
Go to Solution.Its the sort of thing that could possibly be fixed by a battery pull.
With the BB powered on, remove the battery and keep it out for a couple of minutes. Let us know how you get on.

Currently we have the following function:
function GET_main_PHONE (
p_person_id number) return varchar2 is
l_per_address_phone varchar2(60);
l_per_phones_phone varchar2(60);
cursor csr_phones1 is
select max(phone_number)
from per_phones phn,
fnd_sessions f
where phn.parent_id = p_person_id
and phn.parent_table = 'PER_ALL_PEOPLE_F'
and phn.phone_type in ('H1', 'M')
and f.effective_date between phn.date_from and
nvl(phn.date_to,f.effective_date)
and f.session_id = userenv ('sessionid');
cursor csr_phones2 is
select telephone_number_1
from per_addresses adr,
fnd_sessions f
where adr.person_id = p_person_id
and adr.primary_flag = 'Y'
and f.effective_date between adr.date_from and
nvl(adr.date_to,f.effective_date)
and f.session_id = userenv ('sessionid');
begin
open csr_phones1;
fetch csr_phones1 into l_per_phones_phone;
close csr_phones1;
if l_per_phones_phone is not null then
return l_per_phones_phone;
else
open csr_phones2;
fetch csr_phones2 into l_per_address_phone;
close csr_phones2;
return l_per_address_phone;
end if;
end get_main_phone;
this works to pull back the most recent number for the emp record..but I need to ALWAYS pull back the Home number if it is there and I don't know how to do it. I tried to use an if statement w/in the cursor but that didn't work.
Thanks for ANY help!
RobHi,
Try this (not tested):
FUNCTION GET_main_PHONE(p_person_id NUMBER) RETURN VARCHAR2 IS
l_per_address_phone VARCHAR2(60);
l_per_phones_phone VARCHAR2(60);
l_phones VARCHAR2(121);
CURSOR csr_phones1 IS
SELECT MAX(phone_number)
FROM per_phones phn,
fnd_sessions f
WHERE phn.parent_id = p_person_id
AND phn.parent_table = 'PER_ALL_PEOPLE_F'
AND phn.phone_type IN ('H1', 'M')
AND f.effective_date BETWEEN phn.date_from AND NVL(phn.date_to, f.effective_date)
AND f.session_id = USERENV('sessionid');
CURSOR csr_phones2 IS
SELECT telephone_number_1
FROM per_addresses adr,
fnd_sessions f
WHERE adr.person_id = p_person_id
AND adr.primary_flag = 'Y'
AND f.effective_date BETWEEN adr.date_from AND NVL(adr.date_to, f.effective_date)
AND f.session_id = USERENV('sessionid');
BEGIN
OPEN csr_phones1;
FETCH csr_phones1
INTO l_per_phones_phone;
CLOSE csr_phones1;
OPEN csr_phones2;
FETCH csr_phones2
INTO l_per_address_phone;
CLOSE csr_phones2;
RETURN NVL(l_per_phones_phone, '') || '|' || NVL(l_per_address_phone,'');
END get_main_phone;Tip: to post formatted code you must enclose it between {noformat}{noformat} tags (start and end tags are the same) :)

Help in CURSOR when pass parameter for the IN
Hi,
Need some help I have CURSOR that takes a VARCHAR2 and NUMBER but when I run my Procedure it gives invalid number. Here is the CURSOR
CURSOR get_count (p_list VARCHAR2, p_id NUMBER)
IS
SELECT COUNT (*) total_rows,
NVL
(SUM (CASE
WHEN UPPER (cdcode) = 'PASS'
THEN 1
ELSE 0
END
0
) tot_returned,
COUNT (*)
- NVL (SUM (CASE
WHEN UPPER (cdcode) = 'PASS'
THEN 1
ELSE 0
END
0
) diff
FROM testtable
WHERE plistcol IN (p_list)
AND pidcol = p_id;
plistcol is of datatype NUMBER
In my procedure I am building a list to comma separated numbers that goes in p_list parameter of type VARCHAR2 to the cursor i.e.
I have a for loop to build that list e.g.
loop
-- num is of datatype NUMBER
p_list := p_list || num || ',';
end loop
IF (p_list IS NOT NULL)
THEN
p_list := SUBSTR (p_list, 1, LENGTH (p_list) - 1);
END IF;here is how my p_list looks when i pass it on to the cursor
*12,345,678*
and here is how open the cursor
OPEN get_count (p_list, 99999);
and here is the error I get
SQLERRM ORA-01722: invalid number
Now when I hard *12,345,678* in my CURSOR SELECT it works fine, it's only when I pass this as parameter it fails. For example I hard code the values in my CURSOR select it works fine
CURSOR get_count (p_list VARCHAR2, p_id NUMBER)
IS
SELECT COUNT (*) total_rows,
NVL
(SUM (CASE
WHEN UPPER (cdcode) = 'PASS'
THEN 1
ELSE 0
END
0
) tot_returned,
COUNT (*)
- NVL (SUM (CASE
WHEN UPPER (cdcode) = 'PASS'
THEN 1
ELSE 0
END
0
) diff
FROM testtable
WHERE plistcol IN (12,345,678) -- even '12','345','678' works when hardcoded
AND pidcol = p_id;I even tried passing the values in the format *'12','345','678'* but still get the above error. So how can I pass the values to cursor IN clause.
So wondering what might be the issue.
ThanksWhy this kind of coding needs to be avoid - here is one demonstration of one aspect ->

babyekcHi,
You can do like this.
Just write the following code in ur Stored Procedure.
CURSOR C1 IS SELECT ABC_ID, BCD_NAME FROM TABLE_A;
BEGIN
OPEN C1;
LOOP
FETCH C1 INTO TEMP_ABCID, TEMP_BCDNAME;
EXIT WHEN C1%NOTFOUND;
DBMS_OUTPUT.PUT_LINE('ABC ID is ' || TEMP_ABCID);
DBMS_OUTPUT.PUT_LINE('BCD NAME is ' || TEMP_BCD_NAME);
END LOOP;
CLOSE C1;
END;
Before declaring the cursor, declare the variables TEMP_ABCID, TEMP_BCDNAME.

I have a problem with a Patient and a Vaccinations tables whereby I have to have set business rules:

(d) chlorea and typhoid vaccinations are not permitted on the same day.

vis_act in number, vac_vacc in char)
AS
patrow patient%rowtype;
action_over exception;
vdate_before_jan exception;

Please help, have to build on this existing code with a cursor/select and create a new table naming it NEW_V_RECORD with appropriate primary key etc.
ThanksHi,
I would recommend coding your proc something like this:
CREATE OR REPLACE PROCEDURE vacc1 (
pat_id IN CHAR
, vis_vdate IN DATE
, vis_act IN NUMBER
, vac_vacc IN CHAR) AS
patrow patient%ROWTYPE;
action_over EXCEPTION;
vdate_before_jan EXCEPTION;
patient_age_85_vac_limit EXCEPTION;
BEGIN
-- Lock this patient's row in order to prevent concurrent inserts into vaccinations...
SELECT *
INTO patrow
FROM patient
WHERE pid = pat_id
FOR UPDATE;
DBMS_OUTPUT.put_line ('Patient Name is: ' || patrow.pname);
DBMS_OUTPUT.put_line ('Patient''s Adress: ' || TRIM (patrow.address));
DBMS_OUTPUT.put_line ('attempting to insert');
-- Check for invalid situations BEFORE inserting data...
CASE
WHEN vis_act > 2 THEN
RAISE action_over;
WHEN patrow.patient_age >= 85 -- I guessed the field name here...
AND vis_act > 1 THEN
RAISE patient_age_85_vac_limit;
WHEN vis_vdate < TO_DATE ('01-JAN-2008'
, 'DD-MON-YYYY') THEN
RAISE vdate_before_jan;
END CASE;
-- If we got this far - we can safely insert data...
INSERT INTO vaccinations
(pid
, vdate
, action
, vaccinated)
VALUES (pat_id
, vis_vdate
, vis_act
, vac_vacc);
-- COMMIT; -- Move this to your client application - COMMIT'ing in PL/SQL procedures is usually bad transactional programming practice
EXCEPTION
-- No need for rollback statements here - it is automatic when raising errors...
WHEN NO_DATA_FOUND THEN
raise_application_error (-20000
, 'Patient not found with ID number suggested');
WHEN action_over THEN
raise_application_error (-20001
, 'There are more than two vaccinations for this patient');
WHEN patient_age_85_vac_limit THEN
raise_application_error (-20002
, 'The patient is older than 85 and received more than one vaccination');
WHEN vdate_before_jan THEN
raise_application_error (-20005
, 'Visit date is before 1st January 2008');
END;
/Notice that I lock the row via an "SELECT ... FOR UPDATE" - this is very important because you do NOT want two users inserting vaccination data for the same patient at the same time. Due to Oracle's read-concurrency feature (usually very handy) - you can really get burned if you do not serialize access to data. A primary key on vaccinations would take care of this too - but it is safer in my opinion to protect your PL/SQL as well. Read Tom Kyte's book "Effective Oracle by Design" - he goes over this issue in detail with an example room reservation system.
Good luck!

Please help: Mouse cursor on MBP repeatedly freezing for a few seconds
Hi all
I bought a MBP last week, and today I started experiencing problems with the mouse cursor. No matter whether I'm using the trackpad or an external mouse (I've tried using both a wired Mighty Mouse and a wireless Logitech), when I'm moving the cursor it keeps freezing for a few seconds (perhaps less than a second), and then I "regain" control of it, only for it to freeze again after a short while.
The only thing that I can think of that might have something to do with this is that I replaced the 2GB of Apple RAM with 4GB of OWC RAM a couple of days ago. Can this be the reason?
Please help me, as this problem renders the computer impossible to use:(
Thanks in advance
Daniel
PS: I'm running Mac OS 10.5.1 and I've got the Keyboard Freeze Update Installed.Hi.
I have a similar problem, however I realized it is somehow related to weather the airport is on. If I turn it off, there are no freezes. It is weird, and I'm going to go with it to Apple. -
Hi,
I am having issue with my cursor.
My cursor declartion looks like below:
Declare
cursor c1 is
select job_id,delayed_time
from mail_test;
Begin
open c1;
Loop
Fetch c1 into m_job_id, m_delayed_time;
IF c1%FOUND THEN
--Exit when c1%NOTFOUND;
dbms_output.put_line('hai');
dbms_output.put_line(' Job '||m_job_id||' is delayed by '||m_delayed_time||' minutes, ');
EXIT;
END IF;
END LOOP;
close c1;
End;
In mail_test table only one row is there for job 1151, but the above code snippet is displaying 3 rows. Any problem with my looping because I want to display only one row.
O/p
hai
Job 1151 is delayed by 184 minutes,
hai
Job 1151 is delayed by 184 minutes,
hai
Job 1151 is delayed by 184 minutes,
Desired o/p:
hai
Job 1151 is delayed by 184 minutes,
Please help me on this. ThanksI dont want to use any predicate for job_id bcoz I want to select all the records from that table.Strange, that sounds contradictionary: do you want to select all records or just one?
Anyway:
Your other options are changing the query to either:
select distinct job_id
, delayed_time
from mail_testor (dirty one)
select job_id
, delayed_time
from mail_test
where rownum=1Or, if you just want the output once, but loop through all records, you can do something like:
declare
prev_id number;
begin
for rec in ( select job_id
, delayed_time
from mail_test
loop
if prev_id != rec.job_id
then
dbms_output.put_line('hai');
dbms_output.put_line(' Job '||rec.job_id||' is delayed by '||rec.delayed_time||' minutes ');
end if;
prev_id := rec.job_id;
end loop;
end; -
Help with cursor please. . And Syncing Video to Audio.
Hello, and thanks for reading this. I'm starting with a small project to start learning Premier.
I've taken about 25 second clips from some songs and mixed them into a 15 minute mix, I would like to incorperate live tour footage of him preforming the song in sync with the songs so that his mouth is moving at the same time and Hand and body movements and such. .
I'm having a hard time doing this because unlike Adobe Audition when you select a part of the timeline and hit space to play, and then hit space again to pause it and can have the cursor jump back to where it was when you hit play the first time, in Premier when you hit pause it stops where you pause it, and i have to move the timeline, which is very hard to do when I'm zoomed in so far because I need to be presise.
Is there a better way to do this, or any tips you can provide to help me?
So far I've added markers to the beginning and end of each song, but it still needs about 3 secs of fine tuning which is proving to be hard when I have to keep zooming out and moving back.
Thanks so much..These are both great help to me, While I would love to continue hearing more tips I do have a question to add which you may know the answer to.
When using the trim tool to make a video shorter or longer, because when setting the in and out points i can't make them exact until it's on the timeline, can you shorten or lenghthen it per frame, like when using the alt key to move the video, instead of dragging with the mouse?
Thanks so much (: -

where ticketid = v1.engravedid)
where engravedid = v1.engravedid;
update unreadable_cards set case_resolved=2
where case_resolved=1
and serial_number is not null;
end loop;
exception
when no_data_found then
update unreadable_cards set case_resolved=22
where ticketid = v1.engravedid;
when too_many_rows then
update unreadable_cards set case_resolved=23
where ticketid = v1.engravedid;
when others then
update unreadable_cards set case_resolved=24
where ticketid = v1.engravedid;
end;
Here I have problem writing values to the table as this error pops up for every reference to V1 in exception
PLS-00487: Invalid reference to variable 'V1'
I need to be able to raise all three exceptions within the loop so that v1 can be referenced and loop does not exit on encountering the exception and completes for every row fetched by cursor, so that I can track the status of each record on the basis of case_resolved value.
Any help would be highly appreciated
Thanks
SaurabhLet me get that out of me.. I don't like your code
First thing you need to know is, you are not going to hit NO_DATA_FOUND exception in a UPDATE statement. If a update did not modify any row it will not raise NO_DATA_FOUND exception. Check this out
SQL> begin
2 update emp set sal = sal+ 10 where 1=2;
3 end;
4 /
PL/SQL procedure successfully completed.
No exception there. So that is one thing you need to look at.
Second thing I don't like the way you have used WHEN OTHERS exception. What are the exception you are looking at? You should not be having a when others without RAISE. It a bug in the code. You need to fix that.
Assuming your logic behind assigning CASE_RESOLVED is like this.
CASE_RESOLVED = 2 means you have found an exact match for your UNREADABLE_CARDS.ENGRAVEDID in CARD_ACCOUNT.TICKETID
CASE_RESOLVED = 22 means you don't have a match for your UNREADABLE_CARDS.ENGRAVEDID in CARD_ACCOUNT.TICKETID
CASE_RESOLVED = 23 means you have multiple match for your UNREADABLE_CARDS.ENGRAVEDID in CARD_ACCOUNT.TICKETID
CASE_RESOLVED = 24 This does not make any sense. You need to drop this part.
You can do this, You don't need all that PL/SQL. Just a simple SQL like this will do.
merge into unreadable_cards x
using (
select a.engravedid
, max(b.serial_number) serial_number
, case when count(b.serial_number) = 1 then 2
when count(b.serial_number) = 0 then 22
when count(b.serial_number) > 1 then 23
end case_resolved
from unreadable_cards a
left
join card_account b
on a.engravedid = b.eticketid
where a.case_resolved = 1
group
by a.engravedid
) y
on (
x.engravedid = y.engravedid
when matched then
update set x.serial_number = nvl(y.serial_number, x.serial_number)
, x.case_resolved = y.case_resolved;
Above is a untested code. But should work. If any minor error fix it and you should be good to go. -
Dear Experts,
I had requirement whenever user click on user input field. It should pop-up mesage.
Like: in IW51 t-code,when user clicks on PO number,it should throw an pop-up message.
I need help from you regarding cursor click action. whether it is possible to develop the logic in customer-exit or not?
Please suggest me your solutions to solve the issue.
Thanks in advance,

Hi I have seen some where in the code
.what I could not understand is
1.what does the e with clause in this code will do? where it is used frequently and what is the advantage?
2.the temp_holding is a table with only one column.So is it like we can use with caluse in the cursor with only one columned tables?
3.why is the AS keyword used in this?
4.If I want to write a select staement for a cursor like this and see what is the data contained in the cursor ,how to write it ?
thanks in adavnce for your help..

The WITH query_name clause lets you assign a name to a subquery block. You can then reference the subquery block multiple places in the query by specifying query_name. Oracle Database optimizes the query by treating the query name as either an inline view or as a temporary table.

Simply, it is like creating a view local to the query that can be used one or more times in the rest of the query. It has added benefits such as the potential to materialize the results, explicitly push predicates into the subquery, and perform hierarchical queries using the recursive feature.

>
3.why is the AS keyword used in this?Developer preference? It is optional when specifying a column alias, it seems many of the aliases in your query are unnecessary since they just duplicate the existing column name.
4.If I want to write a select staement for a cursor like this and see what is the data contained in the cursor ,how to write it ?You can view the results from the cursor the same way as any select query, e.g.
