How can I get size of fetched data size when run a SQL ?

Hi,
When I run a SQL how can I get fetched data size?
regards,

We can get it using some calculations:
1. SQL%ROWCOUNT attribute will fetch you number of rows returned in a SQL statement.
Problem-->Now you need to get the size of 1 row.
Solution-->
Step 1.We can get size of table from dba_segment data dictionary.
Select block_size from dba_segemnts where segment name like '%YOURTABLE%';
Step2 . Get count of rows in your table
Select count(*) from YOUR_TABLE
Step 3.
Get size of 1 row--> Divide result in Step1 by result in Step 2.
Required result--> multiple result in step3 with SQL%ROWCOUNT..
I hope this is what u want.

Above is my data
I have to fetch the record_type from a lookup where I can have any of the record type, sometime USES, HOW TO USE, SIDE EFFECTS and sometimes some other set of record types
In my report I have to get these record typpes as field name dynamically whichever is available in that lookup and record values against them.
its a BI Publisher report.
please suggest

if you have data in db then you can create xml with needed structure
and so you can create bip report
do you have errors or .... ?

You can't. There is no memory card. It uses flash memory that's soldered to the logic board. If you didn't back it up, your data is gone.

myLoader.addEventListener(Event.COMPLETE, completeHandler);
myLoader.load(req);
function completHandler(event:Event):void {
       var myLoader:URLLoader = event.currentTarget as URLLoader;
       var xmlDP:XML = new XML (myLoader.data);

How can i get the small sircul contact pic when I receive or make calls instade of the full screen pic ?? Cannu help me plz

How can i get the small sircul contact pic when I receive or make calls instade of the full screen pic ?? Can u help me plz

Settings you make in ACR for a Raw file are written to the separate XMP side car file. (The Camera Raw preferences has this set by default and to my opinion it should stay so, but the other option is to save them in a central database)
However, opening the same file in ACR and make new adjustments the previous settings are overwritten by the new ones. You can save them separately but that would be a hell of a job. If you want to be on the safe side you should make a proper back up of the whole folder (be sure to have the XMP files included, by default those are hidden files in Bridge) before someone else starts playing with the settings. However, you can always go back to the default version using the option in the little menu icon next to the name op f the panel (first panel is Basic). click on the icon and from the provided menu choose 'Reset Camera Raw Defaults' to go back to the originals.
I don't use jpeg in ACR very often but I believe ACR settings for jpeg and tiff are written in the XMP data in the file itself instead of a separate XMP file. You can revert to default or make new settings that also overwrite the older settings.
Making adjustments in ACR shows the results in Bridge (it uses the XMP data for the preview) but to make it visible in other apps you also have to save them in Photoshop itself to make the changes persistent so that mail and print reflect your settings.
So basically, let her play with the files and either chose the option to save the files (bottom left in ACR Window and choose the wanted provided options or open and save them in Photoshop to get the proper result. And if you want to be on the safe side let here use her own copies and keep the originals to your self.
