Newbie qn - How do I check if a schema exists?
Hi,
Sorry for askin a stupid qn.
How do I check if a particular schema exists?
Is schema the same as a user?
Thanks,
Mel
After going through other messages I think I have found the answer to my qn.
I guess connecting to sql*plus with the schema name proves that the schema exists. Can someone confirm this?
Thanks,
Mel

How can i check if a procedure exists in a certain database version
So today i became really frustrated after noticing that the Oracle SQL version on some computer I needed to work on was 10.1. The problem with that was that I needed a procedure called "xmlserialize". I browsed the documentation for it, but I didn't see anything like "since 11.0" or something similar.
So.. how can I see what is the first Oracle SQL version that supported some procedure?
For example, when I check a class definition for Java, I consult the javadoc :
http://docs.oracle.com/javase/7/docs/api/java/math/BigInteger.html
and there there's a field called "Since". For BigInteger ( it's just an example ), it says "Since: JDK1.1", so I know that if I'm using a JDK version earlier that 1.1, I won't have that class.
Is there some similar information for Oracle procedures/ functions/ features/ etc?>
Let me be more explicit. I've searched for xmlserialize function.
The only place on the website that holds information regarding this function is this page:
>
To paraphrase sybrand - that's utter nonsense. I have never found only one reference to anything on the web.
Your question subject is

And since you said you were using 10.1 I searched for

http://docs.oracle.com/cd/B19306_01/appdev.102/b14259/whatsnew.htm

That link is for the XML Db Dev Guide for 10g Release 2
Would you like to guess what you find if you search for xmlserialize?
Right on the very first page is this

Oracle Database 10g Release 2 (10.2) New Features in Oracle XML DB
SQL/XML Standard Compliance (SQL:2005 Standard Part 14)
Support for the developing SQL/XML standard has been extended. The following SQL functions have been added: XMLPI, XMLComment, XMLRoot, XMLSerialize, XMLCDATA, and XMLParse. Escaping of identifiers has also been updated, in accordance with a change to the SQL/XML standard. See "Generating XML Using SQL Functions".

How do I check if a table exists
I have some embedded SQL statements to create tables and indexes
in a database. These tables may or may not already be there. I
would like to be able to drop the table(s) first, then create
them. Unfortunately, an error is generated if I drop a table
that does not exist.
Can someone send me the proper SQL command to check if a table
exists before dropping it in Oracle?
TIA

Newbie Qs: how do you check what's stored in media card?
Besides, taking it out and checking it on PC, is there a way to do this through BB?
I just put 2GB card in and it's already 1.8 GB full.
I can account for 0.5GB with pics and songs but like to know and monitor its content.
Verizon 8330 with 4.3 software.
Thanks!
Solved!
Go to Solution.Hi and welcome to the forums,
on 4,3 you can out a 4 or 8gb media card so you are okay there.
DID you notice that instead of a full 2gb, the actual was about 1.8 due to formatting info.
Check the following options:
Media Card window
ON
Encryption
NONE
Mass storage support
ON
auto enable when connected
YES
On your media card do you have these folders:
Blackberry
pictures
music
ringtones
videos
voicenotes
This is the folder structure that the Blackberry needs to allocate the media to.
Do you have these folders on your media card?
Please let me know!

If your requirement is to insert in one table and if the record exists insert into other table the merge statement doesn't work

How to check if an object exists and how to discard it?
Greetings,
I have a main GUI panel in a JFrame that creates a smaller JFrame with a progress bar and text area whenever a process is initiated. I've set the default close operation to DISPOSE_ON_CLOSE as when I set it to EXIT_ON_CLOSE the main GUI panel closes as well (!). But whenever I'm closing the smaller JFrame and initiate a new thread, then the same operation is perform in parallel 2, 3 ,4 times, etc. It seems that the object of the class ProgressGUI which carries all the components of the small panel is not disposed properly. So my question is how can I check if an object exists and if yes how can I discard it? Or in other words how can I discard the JFrame of the small panel without closing the main GUI panel as well?
thanks,
ThomasI've set the default close operation to DISPOSE_ON_CLOSE thats right.
So my question is how can I check if an object exists Whenever you create an object, save its refrence somewhere, then just check
if(reference==null){
//object does not exist
}else {
//object exists
and if yes how can I discard it? Ensure that no references of the object to be discarded are remaining with any of the objects and then believe in 'Garbage Collector' to do the job! e.g. if there is only one reference to the frame (in your case) somewhere, you can just make an assignment like:
reference=null;by doing this, you have made the object a candidate for garbage collection. Rest is done by 'Garbage Collector', not you.
For cases like yours, it is better to make the small frame just once and whenever required just make the frame visible.
e.g.
JFrame smallFrame;
void showSmallFrame(){
if(smallFrame==null)smallFrame=new SmallFrame(); //or something like that
smallFrame.setVisible(true);
}Thanks! -

How does APEX check for null values in Text Fields on the forms?
Hello all,
How does APEX check for null values in Text Fields on the forms? This might sound trivial but I have a problem with a PL/SQL Validation that I have written.
I have one select list (P108_CLUSTER_ID) and one Text field (P108_PRIVATE_IP). I made P108_CLUSTER_ID to return null value when nothing is selected and assumed P108_PRIVATE_IP to return null value too when nothign is entered in the text field.
All that I need is to validate if P108_PRIVATE_IP is entered when a P108_CLUSTER_ID is selected. i.e it is mandatory to enter Private IP when a cluster is seelcted and following is my Pl/SQL code
Declare
v_valid boolean;
Begin
IF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := TRUE;
ELSIF :P108_CLUSTER_ID is NOT NULL and :P108_PRIVATE_IP is NULL THEN
v_valid := FALSE;
ELSIF :P108_CLUSTER_ID is NULL and :P108_PRIVATE_IP is NOT NULL THEN
v_valid := FALSE;
END IF;
return v_valid;
END;
My problem is it is returning FALSE for all the cases.It works fine in SQL Command though..When I tried to Debug and use Firebug, I found that Text fields are not stored a null by default but as empty strings "" . Now I tried modifying my PL/SQL to check Private_IP against an empty string. But doesn't help. Can someone please tell me how I need to proceed.
ThanksSee SQL report for LIKE SEARCH I have just explained how Select list return value works..
Cheers,

How do I check Edge status?
How can I check on the Edge network status?
I suddenly can't connect to the Apple mail server to send/check email and can't view anything on the Web, but the 'E' still shows up that the network is there.
Is there a place to check on the Edge network status?
I couldn't find anything but a coverage map that doesn't tell you anything except what areas are covered for voice or data coverage (but not current status).I'm not aware of any status sites that give the status of a particular tower. Sometimes, putting the phone in airplane mode for a minute will correct the issue.

I have a MacBook Pro from '07 with 1 GB of memory. The battery is shot and my AppleCare has run out. I just upgraded the OS to 10.6.8. But a few questions:
1 - How do I even check how much memory I have left on this computer?
2 - How do I check how many battery cycles are left?
3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11 because I can generate pdf's from Word. Roughly how much RAM does Office '11 take up?
4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
5 - How much does 1 more GB of memory cost?
AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
Or does it make more sense to just get a new computer entirely? (trying to avoid this).
ANY help would be sooo appreciated! Thanks.1 - How do I even check how much memory I have left on this computer?
If you're asking how to check to see if you need more RAM, open Activity Monitor and go to the System Memory tab, then compare page outs and page ins. If page outs is 10% or more of page ins, you probably need more RAM.
2 - How do I check how many battery cycles are left?
There's no limit on the number of battery cycles, it's just that the more cycles you've used the more "worn out" your battery gets. You've got a 4-year-old machine, and if it's still got the original battery, it's probably about time for a replacement battery. You can check battery health using System Profiler... look at the Power section under Hardware.
3 - I want to upgrade to Microsoft Office '11 because I don't have Adobe Acrobat to creat pdf's and I need to be able to do this for school... Instead of buying acrobat, I figured I would just upgrade to Office '11
You don't need Office 2011 to create PDFs. Any application capable of printing can create PDFs on a Mac. Just choose File -> Print, but instead of clicking the Print button in the print dialog, click the PDF button and choose Save As PDF in the menu that appears.
4 - Does Apple still make batteries for this computer (from '07)? How much do they cost?
5 - How much does 1 more GB of memory cost?
I'll "ditto" sig's answers to these.
AND lastly -- is it even worth it to spend the $ on more RAM, a new battery and Office '11?
Or does it make more sense to just get a new computer entirely? (trying to avoid this).
If Office 2004 is still working fine for you, stick with that and don't incur the costs of Office 2011. As to the RAM, only add more if the test I mentioned above indicates that you need it. If you buy more RAM when you don't really need it, you won't see much (if any) performance improvement. That just leaves the battery... and if the machine is still doing what you need it to do and you don't really need a new machine for anything, you could definitely buy a new battery and get a few more years out of it. -
How do you check Memory Speed on ICD
Hi everyone
I am new to the forums and I am also a soon to be first time mac owner(Receiving my 20" ICD this week) .
I am buying the imac with an extra 1gig DIMM installed, non-apple memory.
Now the reseller assures me that the 3rd party memory that he'll be using is compatible with the imac.
I'm assuming that if there are no issues at start-up then the memory is compatible, but I would like to know how can I check that the memory is running at 667 mhz and that he did not install 533 mhz memory.
So how can I check that the memory is running at 667?
Thank you in advance
20" Imac ICD 1.5ghz memoryAh, I think I'm reading that you may be concerned about a potentially counterfeit SO-DIMM. That's one reason to buy direct from a reliable seller such as Apple or Crucial. I'm not sure the memory utility Memtest will verify the DIMM's speed, but it will verify whether or not the SO-DIMM is working properly. That might include a speed calculation, and possibly you can email the Memtest author to find out.
