XML in Oracle 9i (best method to return a xml file from a table query)

Hello.
What is the best method to query a table, or set of tables (that will return thousands of rows) using xml in oracle? (best performance)
I'm currently using DBMS_XMLGen, is there a better method ?

I think, if your talking about generating XML, that you should use XMLElement, XMLForest, etc. to create your XML.
Lets assume that you base is relational data, then maybe the following great example will give you an idea how to do it : Re: Generate XML Schema from oracle tables
As michaels pointed out (did you read the link/ URL given?), the general expectancy is that the packages will be less and less important. So also maintenance wise the XMLElement, etc way will be the best, also for the future, maintainable method.

What is the best method to import my iPhoto library from my macbook to my new iMac [27"]?

What is the best method to import my iPhoto library from my macbook to my new iMac [27"]?

You can copy your iPhoto Library to an external hard disk, USB flash drive, or other media (depending on the size of your iPhoto library). Then, you'd copy the iPhoto Library from that media to the same location on your iMac.
Using the Finder, navigate to your Home folder (or click on Go from the menu bar and click on Home). Open the Pictures folder, select your iPhoto Library and then from the menu bar choose "Edit" and then "Copy". Then navigate to your external disk, click on "Edit", and then click on "Paste".
Then, insert your media on the iMac, and copy the iPhoto Library from your external media to the same location on your iMac (the Pictures folder located under your Home folder).
Hope that helps, have a great day.

Best Way To Extract Large Text Files From Query

Using CF7/SQL Server 2000. I need to extract about 50,000 records from another server, and save it to a .CSV file. Not sure what the best method is for this. I've got the query written, and it will pull all the records. But don't want to display them on the screen, just store in a .CSV file somewhere on the server.
I've looked at CFFILE and CFDIRECTORY, and those don't seem to be the best tools for this. What about using CFCONTENT with CFHEADER? I use that to output to Excel files
<CFCONTENT type="application/vnd.ms-excel">
<CFHEADER NAME="Content-Disposition" VALUE="attachment; filename=c:\mydir\myfile.xls">
But when trying to use it, it doesn't save the file on my drive. Would appreciate advice on the best tools/tags for extracting large volumes of data from other servers, and saving to a local file.
Once working, ultimately, I'd like to set it up, so the .CFM job runs daily, automatically, extracts the data and FTP's it to another server. I've seen the CFFTP tag, but until I can get a file saved on my drive, or another server's drive, there's nothing to FTP. Thanks for any help/advice.
Gary

Thanks, but I can't find any good examples of using CFFILE (just syntax of the tag, which doesn't make a lot of sense). I've been writing CF code for 8 years, and feel I can make it sing and dance. But I didn't understand how CFFILE worked, from reading the online documentation and my Ben Forta books. There are no good examples. Do you still write the query with CFQUERY, then "substitutute" CFFILE for CFOUTPUT? Or enclose CFFILE inside CFOUTPUT? I can't find any examples that explain this.
I just need to see a basic example of CFFILE "in action." Starting with a simple query, and a simple output that writes the query results to a file.
Lastly, once you have the data written to a file, using CFFILE, is that when you can use CFFTP, to FTP that file, (or any file on the hard drive for that matter) to another server?
Thanks for help, and any simple examples, just to get me started. Thanks.

Return a flat file from an RFC

Hi,
I have created a function module that at the moment returns 4 tables. I want to create a flat file based on these tables and return that file from the function instead of the tables. I can create a flat file using the function GUI_DOWNLOAD.
Is there a way to return a flat file from the function?
Regards,
Mark

No, but you can return all four tables in single flat table. First you would need to create a structure in SE11, it would have one field, of type string. In your function module interface, you would have a tables parameter like the structure that you just created. No in the code of the function module, instead of writing your data of each internal table to the corresponding tables parameter to update the one table with the flat structure.
Make Sense?

Best Method of Backing Up Computer Files

Hi,
What is the best way of backing up your computer files (Almost like a clone of the MacIntosh HD with MAC OS X (Snow Leopard OS 10.6.2)) in case of a hard drive crash? I am new to Mac and I wanted to have a back up in case of a hard drive crash. So I could retrieve my files from whereever. Any and all ideas will be appreciated.
Thanks,

There are three basic types of backup applications: *Bootable Clone, Archive, and Time Machine.*
This is a general explanation and comparison of the three types. Many variations exist, of course, and some combine features of others.
|
_*BOOTABLE "CLONE"*_
|
These make a complete, "bootable" copy of your entire system on an external disk/partition, a second internal disk/partition, or a partition of your internal disk.
Advantages
If your internal HD fails, you can boot and run from the clone immediately. Your Mac may run a bit slower, but it will run, and contain everything that was on your internal HD at the time the clone was made or last updated. (But of course, if something else critical fails, this won't work.)
You can test whether it will run, just by booting-up from it (but of course you can't be positive that everything is ok without actually running everything).
If it's on an external drive, you can easily take it off-site.
Disadvantages
Making an entire clone takes quite a while. Most of the cloning apps have an update feature, but even that takes a long time, as they must examine everything on your system to see what's changed and needs to be backed-up. Since this takes lots of time and CPU, it's usually not practical to do this more than once a day.
Normally, it only contains a copy of what was on your internal HD when the clone was made or last updated.
Some do have a feature that allows it to retain the previous copy of items that have been changed or deleted, in the fashion of an archive, but of course that has the same disadvantages as an archive.
|
_*TRADITIONAL "ARCHIVE" BACKUPS*_
|
These copy specific files and folders, or in some cases, your entire system. Usually, the first backup is a full copy of everything; subsequently, they're "incremental," copying only what's changed.
Most of these will copy to an external disk; some can go to a network locations, some to CDs/DVDs, or even tape.
Advantages
They're usually fairly simple and reliable. If the increments are on separate media, they can be taken off-site easily.
Disadvantages
Most have to examine everything to determine what's changed and needs to be backed-up. This takes considerable time and lots of CPU. If an entire system is being backed-up, it's usually not practical to do this more than once, or perhaps twice, a day.
Restoring an individual item means you have to find the media and/or file it's on. You may have to dig through many incremental backups to find what you're looking for.
Restoring an entire system (or large folder) usually means you have to restore the most recent Full backup, then each of the increments, in the proper order. This can get very tedious and error-prone.
You have to manage the backups yourself. If they're on an external disk, sooner or later it will get full, and you have to do something, like figure out what to delete. If they're on removable media, you have to store them somewhere appropriate and keep track of them. In some cases, if you lose one in the "string" (or it can't be read), you've lost most of the backup.
|
_*TIME MACHINE*_
|
Similar to an archive, TM keeps copies of everything currently on your system, plus changed/deleted items, on an external disk, Time Capsule (or USB drive connected to one), internal disk, or shared drive on another Mac on the same local network.
Advantages
Like many Archive apps, it first copies everything on your system, then does incremental backups of additions and changes. But TM's magic is, each backup appears to be a full one: a complete copy of everything on your system at the time of the backup.
It uses an internal OSX log of what's changed to quickly determine what to copy, so most users can let it do it's hourly incremental backups without much effect on system performance. This means you have a much better chance to recover an item that was changed or deleted in error, or corrupted.
Recovery of individual items is quite easy, via the TM interface. You can browse your backups just as your current data, and see "snapshots" of the entire contents at the time of each backup. You don't have to find and mount media, or dig through many files to find what you're looking for.
You can also recover your entire system (OSX, apps, settings, users, data, etc.) to the exact state it was in at the time of any backup, even it that's a previous version of OSX.
TM manages it's space for you, automatically. When your backup disk gets near full, TM will delete your oldest backup(s) to make room for new ones. But it will never delete it's copy of anything that's still on your internal HD, or was there at the time of any remaining backup. So all that's actually deleted are copies of items that were changed or deleted long ago.
TM examines each file it's backing-up; if it's incomplete or corrupted, TM may detect that and fail, with a message telling you what file it is. That way, you can fix it immediately, rather than days, weeks, or months later when you try to use it.
Disadvantages
It's not bootable. If your internal HD fails, you can't boot directly from your TM backups. You must restore them, either to your repaired/replaced internal HD or an external disk. This is a fairly simple, but of course lengthy, procedure.
TM doesn't keep it's copies of changed/deleted items forever, and you're usually not notified when it deletes them.
It is fairly complex, and somewhat new, so may be a bit less reliable than some others.
|
RECOMMENDATION
|
For most non-professional users, TM is simple, workable, and maintenance-free. But it does have it's disadvantages.
That's why many folks use both Time Machine and a bootable clone, to have two, independent backups, with the advantages of both. If one fails, the other remains. If there's room, these can be in separate partitions of the same external drive, but it's safer to have them on separate drives, so if either app or drive fails, you still have the other one.
|
_*OFF-SITE BACKUPS*_
|
As great as external drives are, they may not protect you from fire, flood, theft, or direct lightning strike on your power lines. So it's an excellent idea to get something off-site, to your safe deposit box, workplace, relative's house, etc.
There are many ways to do that, depending on how much data you have, how often it changes, how valuable it is, and your level of paranoia.
One of the the best strategies is to follow the above recommendation, but with a pair of portable externals, each 4 or more times the size of your data. Each has one partition the same size as your internal HD for a "bootable clone" and another with the remainder for TM.
Use one drive for a week or so, then take it off-site and swap with the other. You do have to tell TM when you swap drives, via TM Preferences > Change Disk; and you shouldn't go more than about 10 days between swaps.
There are other options, instead of the dual drives, or in addition to them. Your off-site backups don't necessarily have to be full backups, but can be just copies of critical information.
If you have a MobileMe account, you can use Apple's Backup app to get relatively-small amounts of data (such as Address book, preferences, settings, etc.) off to iDisk daily. If not, you can use a 3rd-party service such as Mozy or Carbonite.
You can also copy data to CDs or DVDs and take them off-site. Re-copy them every year or two, as their longevity is questionable.
Backup strategies are not a "One Size Fits All" sort of thing. What's best varies by situation and preference.
Just as an example, I keep full Time Machine backups; plus a CarbonCopyCloner clone (updated daily, while I'm snoozing) locally; plus small daily Backups to iDisk; plus some other things to CDsDVDs in my safe deposit box. Probably overkill, but as many of us have learned over the years, backups are one area where +Paranoia is Prudent!+

Hi,
Namespace issue.
You have to declare it in the XQuery prolog :
DELETE FROM document
WHERE XMLExists( 'declare default element namespace "urn:hl7-org:v3"; (::)
                  $p/document/id[@root=$root_value]'
                 passing object_value as "p",
                         '03d6a2cd-fdda-4fe1-865d-da0db9212f34' as "root_value" )

2. Write ABAP program
Which includes declaration of internal tables
that you need "IT_DATA".
Upload XML data to an internal table "IT_XML "
use below statement to convert XML to internal table.
Call transformation ZTRANS
source XML IT_XML
result IT_DATA.

How to return the entire row from a table

Hi guys,
Tabl A
FirstName varchar2(10),
Age Number,
Add varchar2(100),
Table B
Filedname varchar2(200), -- contains all the fields of table A
Datatype varchar2(100), -- Contains the datatypes of the filedname
Length Number -- contains the length of the fileds
Now how can i return the entire row from table A with the datatype and its length.
Any help would be appreciated ?
Here is the query I wrote but it how to take the datatype and its length..
create or replace procedure disp_table_data
as
type r_cursor is REF CURSOR;
c_A r_cursor;
er A%rowtype;
begin
open c_A for select * from A;
loop
fetch c_A into er;
exit when c_A%notfound;
dbms_output.put_line(er.FirstName||'--'||er.Age);
end loop;
close c_A;
END;
/

Guys,
I want column value from table A and its corresponding data_type and length from table B. I think I cant do it through joins.
Any idea would be appreciated ?.
Example ..
Tabl A
FirstName varchar2(10),
Age Number,
Add varchar2(100)
insert into A values('John',24,'Boston');
Table B
Filedname varchar2(200), -- contains all the fields of table A
Datatype varchar2(100), -- Contains the datatypes of the filedname
Length Number -- contains the length of the fileds
insert into B values('FirstName','varchar2',10); -- this is coming from table A.
Output should be like this...
John,Varchar2,10
Here (John is the FirstName - coming from table A, Varchar2 is a Datatype and 10 is the Length which are coming from table B ). Only column values are coming from table A , corresponding datatype and length are coming from B.
Any idea would be appreciated ?
Thanks.

Best way to copy large VM files from one drive to another?

Hi all, I am wondering what the best and fastest way there is to copy a large VM file from one drive to another (external drive to internal drive). Should the .pvm folder (in my case with Parallels) be zipped first? The files I need to copy range from 50 to 70gb. thx for any insight! ps. Even Bombich admits it's difficult for CCC to do...not clear why, but it does slow a full clone down to a crawl. I also have Chronosync at my disposal, but suspect the same is true there as well. Cheers!
coocoo

I don't think it matters much which way you do the job. I use Parallels to compress by drives on a regular basis. If you want to copy a dynamic VM, which can grow to just about any size as required, to another drive you will use about the same amount of time zipping the VM - transfering the VM - unzipping the VM, as you would just moving the VM.
I've moved my VM files to a second partition that does not get cloned to my bootable backup that I create with SuperDuper. I've excluded my entire VM folder from Time Machine and just make zipped backups for each system after any large Service Pack Updates from Microsoft, or any intricate program installations. These get copied to a second partition on my Time Machine drive manually.
My VM's sizes are kept under control by using common Documents-Movies-Music folders for the Mac and the VM's. My VM's do not have the data files the programs use, they are on my Mac and get backed up every hour with Time Machine.
Reinstalling a VM just means deleting the broken copy, unzipping my latest backup, and putting into the same folder that Parallels knows to use. The data files are always accessible, even if they were created after my latest VM backup.

Generate XML file from DB table

Hi all,
I am trying to retrieve data from a DB table and generate an XML file.
I am using Oracle8i and IIS 4.0. I have downloaded XML parser for PL/SQL and XSQL Servlet. Also I have Jrun to enable IIS to process Jservlets
Here are my questions,
1. Do I need any other software ?
Also do I need both XML parser for PL/SQL and XSQL Servlet ??
2. What is the next step I should do ?
Please help me. Thanks in advance.
Vikki

You downloaded the wrong XML Parser!
XSQL requires Java Parser. Well, there's a copy included with the XSQL package so you actually don't need to do another download.
You really don't need XSQL if you just want a XML file from DB, you just needed a XML SQL Utility. Download that and run the samples.
