SQL cursor problem
Hi allI want to see the records in the table emp or a message if the emp table is empty, but under cursor shows the two,
How can I solve this problem, please help.
declare
cursor emp_cur is
Select * from emp;
SheikYerbouti emp % rowtype;
Start
Open emp_cur;
loop
extract in SheikYerbouti emp_cur;
If emp_cur % notfound then
dbms_output.put_line ('there no record in the employee table');
"exit";
on the other
dbms_output.put_line (emp_rec.empno |) » '|| emp_rec.ename);
end if;
end loop;
close emp_cur;
end;
You should do something like this,
not tested.
DECLARE
CURSOR emp_cur
IS
SELECT * FROM emp;
emp_rec emp%ROWTYPE;
i NUMBER := 0;
BEGIN
IF emp_cur%ISOPEN THEN
CLOSE emp_cur;
END IF;
OPEN emp_cur;
LOOP
FETCH emp_cur INTO emp_rec;
EXIT WHEN emp_cur%NOTFOUND;
i := i + 1;
DBMS_OUTPUT.PUT_LINE (emp_rec.empno || ' ' || emp_rec.ename);
END LOOP;
IF i = 0 THEN
DBMS_OUTPUT.PUT_LINE ('There is no record in employee table ');
END IF;
CLOSE emp_cur;
END;
Earlier you were printing that the records did not exist for when the extraction fails. Extraction fails at the end of the recording for any cursor. If you have found the two.
Now, you print it out only if message I = 0, which means that the cursor did not return a single record.

After a few hours, my mouse cursor gets... weird. She becomes a fatter version of himself (in his goal a bit biased as well) with multiple copies, overlapping itself in different colors. The cursor "hovering on the text" is not affected, its 'I' used remaining shape, but others, including the slider "arrow" by default and the "hovering on the hyperlink pointing to the hand" is weird. Turning on the traces of the mouse leaves a copy of the weird arrow cursor, but the normal mouse comes back and works well.
So, basically, how to avoid this strange, large, multicolored, slider which came into existence, and the case of activation of the traces of the mouse * is * the only way to turn it off, how can I get rid of the weird, big, multicolored cursor unsightly that lingers on my screen? Virus scan has not turned up all wicked. Would it be a specific program (it's a gaming computer and not all games are perfect...) which irritates my computer in a certain way and results do?
NOTE: I use a special gaming mouse or anything like that. It's a Dell which came with a (different) computer that I got years ago. Device Manager indicates that the drivers are up to date. I don't think it's a problem with this mouse especially, but I have no real way to check a different mouse on this computer without having to buy one.
Thanks for reading.
I'd be willing to bet that it's your video card driver. My Dell has an ATI video card and it happens sometimes. I have a graphics card dual monitor and oddly enough happens that on my primary monitor - display of the cursor on the screen 2 is not affected.
ATI made a patch for cursor problems, unfortunately the Dell that I use is in a corporate environment and they did not find enough critical to give me the patch again.
You could try the Dell support page, go to the downloads section and make sure you have the latest video card driver.

Original title: Focus cursor problem
I can't get my cursor will appear in a search box (e.g., Google, amazon.com, etc.) in Firefox Version 16. It seems to be a kind of focus problem. Is it a Firefox problem or a problem of Windows 7? Could this be a script problem? Thanks for any ideas on how to solve this problem.

Parsing sql - cursor parent and child
Hi all
What is the parent and child when parsing sql cursor?
Thank you
JohnWell, as Anand mentioned you could yourself. Here's a demo of the workaround based. Based on the change of environment, the sliders would be created and will not be shared that I made using the change of parameter of optimizer_mode. This is done in 11201 with the setting optimizer_features_enable on 10201.

Windows 7 displays the error message when you exit + cursor problem
Two issues here. Phoshop CS5 on Wind 7 64-bit.
Number of physical processors: 8
Processor speed: 3073 MHz
Built-in memory: 12279 MB
Free memory: 9577 MB
Memory available to Photoshop: 10934 MB
Memory used by Photoshop: 80%
Tile image size: 128KFirst issue is since the last update automatic Adobe (why fix what is not broken?) Whenever I go out now Photoshop I get the message "Server QT Adobe has stoped working" and sometimes when I go out the bridge. InDesign behaves as evil. I can no longer start a previous document in the file without ID Manager crashing on.
The other is the sliders in the Clone and delete lose their advantage (become invisable) without any reason - well not quite. Noise Ninja crashed in Photoshop when I tried to use it. I reinstalled it and all is well. The issue of cursor seems to be intermittent but came back (for no reason), after that I reinstalled NN. I can't seem to change the cursor, no matter what I do. The problem now seriously affect how I work. Almost any return to Win XP, who ran perfectly in Photoshop CS5.
Any help will be accepted with gratitude.
Doug
Cursor problems are known to be caused by outdated video drivers (nVidia).
Assuming you have a nVidia (which model?) video card, go to their web site and download and install the latest video drivers for your card.
Also, this could very well solve your crash.
Don't forget the video drivers to apply the OpenGL system, on which Photoshop relies heavily.

PL/SQL: Cursor with list filling can do IF EXISTS on Table
Here's my problem. The DB I work with is a database of events (network events). I have a task to take a list of nodes of 2600 and see whether these nodes exist in a set of events that would be with a certain WHERE clause. On my first pass, I did WHERE AND NŒUD clause in (list of 2600 nodes). Well you can put only 1,000 items in a list so I've divided into 3 reports and served while a UNION all between them. This used 15% of the resources of the db and ran for hours and the Group dba like me to find a better way. They would prefer that I use PL/SQL.
I am new to pl/sql (but not programming or SQL). So the first thing I've done is just figure out how to get my list in a Varray, which I then went to a table because I couldn't find examples, after hours and hours of searching the Web,.
referencing a Varray with SQL syntax.
START CODE sample 1 *.
DECLARE
DECLARE
TYPE NodeList IS TABLE OF VARCHAR2 (255);
Node NodeList: = NodeList ('node1', node2', [.. .list of 2597 nodes..], 'node2600')
BEGIN
dbms_output. Enable (1000000);
FOR i IN Nodes.FIRST... Nodes.LAST
LOOP
DBMS_OUTPUT. Put_line (' relevant points: ' |) Nodes (i));
END LOOP;
END
END CODE Sample 1 *.
The pseudo-code I'm envisioning goes something like this:
IF one of these nodes (nodes of 2600 list),
There are in the nodes for this WHERE clause (which is taken from the event db table).
then print the records (of the events in the event db table) that contains the nodes (ie the list nodes).
I think I found an example with 2 sliders, but I can't find this example once again. And anyway, I can't figure out how to get my list in a cursor. I have many examples of how to complete a cursor on a select statement against a database.
I tried this but it did not work:
START the CODE sample 2 *.
DECLARE
DECLARE
TYPE NodeList IS TABLE OF VARCHAR2 (255);
Node NodeList: = NodeList ('node1', node2', [.. .list of 2597 nodes..], 'node2600')
CURSOR MOM_OVO_NODES IS
SELECT the node
OF NodeList
ORDER BY node;
BEGIN
dbms_output. Enable (1000000);
FOR nodelist_rec IN MOM_OVO_NODES
LOOP
dbms_output.put_line (' relevant nodes: ' | nodelist_rec.) Node);
END LOOP;
END
END CODE sample 2 *.
Is there a way to get this list in a slider? Or I think about this correctly?

Your best bet would be to maintain a table of nodes. You can then use a single SQL query with an IN WHERE clause as:
WHERE node in (SELECT node FROM node_table)Or you can use a join (the method preferred honestly, gives Oracle more optimization options).
If you don't want to maintain a table of node, you can always create a global temporary Table or the external Table that could be loaded prior to running your report.
If you have tried these methods, and it is still too low or high intensity of resources, then we should look at the SQL and chorus only. See the PL/SQL FAQ's for more information on setting the SQL statements.

Hello Experts!
I'm trying to update one of my table after making a few changes. I don't know why I'm not able to do this simple task. I spend a lot of time but could not able to find the problem. Can anyone here to show me my mistake or correct.
Here is my code
-UPDATED THROUGH CURSOR
Set serveroutput on
declare
cursor c_emp_sal is
Select * from adeel_emp_007
update of the salary;
Start
for r_c_emp in c_emp_sal
loop
Update adeel_emp_007
Set salary = salary * 1.1;
the location being c_emp_sal;
end loop;

end;
Thanks in advanceWhy not?

Why get ORA-00942 during the validation of PL/SQL cursor
The database is 10 gr 2.
ST_PKG_UTILITIES contains a procedure called "p_insert_update_person_info".
The procedure includes a cursor that selects a view 'CDS_CIS_ETHNICITY '.
I am logged in as the owner of the schema of the package. The view lies in another schema, but I have the right to SELECT on the view.
When I try to compile the package, I get "ORA-00942: table or view does not exist", pointing to the CDS_CIS_ETHNICITY view.
However, if I SELECT directly from the view using a SQL window, it returns information without problem.
Code view is a SELECT statement on a table across a db_link. However, given that I can select directly from the view, I am not clear why I would get the error because the view is selected, within PL/SQL.
Note that the table was originally, on the same server that the schema that I am now, so no db_link was necessary. When the schema of the table has been moved to a new server, we added the db_link. However, the package was never changed, we were careful to reproduce the names of objects that are used by the package, when building the db_link.
Ideas on this issue would be appreciated.
Thank you

Grant privileges directly to the owner of the whole.
Looks like the privileges that you have about this point of view have been granted to a role, and the owner of the package has this role.
Roles do not count inside stored procedures. You must have privileges granted directly to the owner (or to the PUBLIC, which probably does not apply in this case). -
Hello
The cursor on my MacBook Air selects texts, emails or icons out of the Blues; the cursor moves to other locations during the strike and does not allow to type a complete sentence. I disabled all the gestures the trackpad section of system preferences, I started the Mac Safeboot mode a couple of times and nothing has solved the problem. It's a MacBook Yosemite 10.10.5 2012.
Any suggestion on how to solve this problem?
Thank you
There are several possible causes for the behavior. Please take each of the following steps that you have not already tried until it is resolved. Some may not apply in your case.
1. follow the instructions provided in this support article, so this one, as appropriate. A damaged or defective power adapter could be the cause, even if it's the right kind.
2 simultaneously press the four corners of the trackpad and release. If there is no effect, it is likely to be temporary, and in this case the device must be repaired or replaced.
3. disconnect or turn off each Bluetooth or USB pointing device, one at a time, testing as you go. You may be able to identify one that is defective. By a pointing device "," I mean a device that moves the cursor, trackpad, mouse, trackball, or tablets. A regular keyboard isn't a pointing device. If you have a desktop without a built-in trackpad design, at least an external pointing device must be active at all times.
4. If your model has an infrared receiver for use with an Apple Remote, turn off .
5. This step is applicable if you are using a Mac laptop with a built-in trackpad, and you also use an external mouse or trackpad. Open the accessibility in System Preferences pane, and select mouse and Trackpad in the menu on the left. Check the box marked
Ignore the built-in trackpad when mouse or a trackpad wireless is present
Credit for this observation to the members of the CSA PattMK.
6. reset the system management controller.
7. If you use a mouse or a trackpad, Bluetooth, investigate potential interference sources, including 3 USB devices.
8. a swollen in a laptop battery can encroach on the trackpad underneath and cause erratic behavior. If you have trouble clicking the trackpad, it is probably the reason. The battery must be replaced without delay.
9. a faulty device or a damaged cable can cause the built-in trackpad to a MacBook to behave erratically. If you use the wired devices, disconnect them one at the time and the test.
10. There is also a report of movement erratic cursor caused by an external display that was plugged in but not turned on.
11. If you use transfer, disable it in the general pane of system preferences.
12. If the mirroring of airtime to a TV is turned on, turn it off.
13. If none of the above apply, or if you have another reason to believe that your computer is remotely controlled, pull it out of the network by turning off Wi - Fi (or your Wi - Fi access point), disconnect a Bluetooth network connection, then unplug the Ethernet cable or a USB modem, whichever is applicable. If the movement of the cursor stops at the same time, you should suspect an intrusion.
14. an appointment of 'Genius' in an Apple store to do the machine or the tested external trackpad.

Hello
I have a lot of problems of cursor on a new Libretto W100. Using the field courses on the display it move it in the opposite on the top of the screen. Then I go to the right below, the cursor moves in the direction towards the top left. The only way I found to stop this problem is a full reboot. And then it works OK, but when I close the lid and leave it alone for two hours, for example, come and activate the problem reappears. I especially don't even touch screens to avoid confusion between the machine. But I can reproduce it consistently.
Very annoying. Any seen elsewhere or have a solution?
Kind regards
