procedure that will dynamically build the query data and table Medallion

Hi people,

I write a procedure that dynamically build the query data and insert in the table "dq_summary".
enforcement procedure with success and data not inserted into the table 'dq_summary '.

I'm sorry. But there is no kind of say that way. The code is undesirable. The approach is wrong. This will not happen. This will cause the fragmentation of memory in the shared Pool. This will lead to another session being impossible to analyze the sliders because of the fragmented memory.

Not only that. The underlying data model is questionable.

All this seems a candidate perfect as an example of how NOT to design and code and use Oracle.

Build the query to select date with status

Hi guys,.
Grateful if you can advise me on how to build the query on below scenario:
Table A
Date
11.44.39.000000000 12-OCT-14 AM ASIA/SINGAPORE
11.44.35.000000000 16-SEP-14 AM ASIA/SINGAPORE
11.44.42.000000000 22-SEP-14 AM ASIA/SINGAPORE
The result of the query:
Date Status
11.44.39.000000000 12-OCT-14 AM ASIA / SINGAPORE inactive
11.44.35.000000000 16-SEP-14 active AM ASIA/SINGAPORE
11.44.42.000000000 22-SEP-14 AM ASIA/SINGAPORE inactive
Basically, the logic, I wanted is
Active principles: today date or max (date) < sysdate
Otherwise will be inactive
And there is 1 active date in time.
Thanks in advance

Sorry, we don't know what you want.

Are you saying that 1 row (maximum) can be assigned status = 'Active' and if 2 or more lines are eligible, the last of them will be called 'Active'?

If so:

CASE

WHEN tmstmp<=>

OR ROW_NUMBER () OVER (PARTITION BY CASE

WHEN tmstmp<=>

THEN "could be."

ANOTHER 'No Way'

END

ORDER BY tmstmp DESC

) = 1

THEN "active."

ELSE 'inactive '.

END

If you would care to post CREATE TABLE and instructions INSERT for some samples, so I could test it.

DATE is not a very good name for a column, especially if the column is a TIMESTAMP, not a DATE. I called the TMSTMP instead of the DATE column.

Why will not erase the working data.

I have been a loyal Firefox user and have never had a problem until now. I've always used clear data to erase history. I know the procedure and how to do it. Recently it has stopped working. It allows to erase all data, as it is called. Now after that it gives me the "deleted data" signal, everything is still there. I tried to uninstall and reinstall Firefox, but it made no difference. What should I do? Thank you.

This is the problem:

Once to help clear the private data with history checked: when you go to the Home tab and slide to the story, all entries are still there?

A user reported that this can be caused by activating the hidden settings in Android Developer. Here's where you who goes offshore:

Android menu > settings > options developer

Then uncheck the "do not keep activities."

If this isn't the problem, could describe you more in detail?

call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. The other rows are based on the entities

Hi Experts,
JDeveloper 12.1.3.0.0
I have a VO based on entity object. With a column of the VO is transient attribute (I created).
I need to call a stored procedure for each row in the transitional attribute and display the data in the form of af: table. As well as other attributes.
So can anyone suggest how can I achieve this?
Thank you

I think that you need a stored function (which returns the value) in this case, is not?

Take a look at:

Is it possible to make a reflection of the image that will change with the image? [was: reflection]

Is it possible to make a reflection of the image that will change with the image?

I believe that a dynamic object will solve your problem.

Place your original image to a new file as a smart object and do the same for reflection (made by processing, reducing the opacity and introduce a slight blur horizontal) on its own layer, then:

by double clicking on the smart object in the layers panel and return to the original image, any change in the original and save, automatically update the vertical image and its reflection.

How to force the Photos up-to-date original jpeg file after you have added the GPS data and rotation

Hello

Pictures has the ability to add GPS data to an image file, but stores the GPS data in a catalog instead of the actual image file. The same seems to apply to the rotation of the image. Is there a way to force the Photos up-to-date the actual image file?

The only solution I have found so far is to export images updated, remove them from the library of Photos and re - import. This process, however, replaces the original creation date with the date of the export in the file. (i.e. a photo taken in 2007 with a creation date of 2007 will now have the date it has been exported photos as a creation date.)

The reason why I want to update the original file, it is that I use Google Photos automatically create albums using the content of the image, the GPS data and dates. The backup utility Google downloads the file Master Original therefore excludes files and changes to images in the photos.

I use the photo Version 1.5 (370.42.0)

Thank you.

The same seems to apply to the rotation of the image. Is there a way to force the Photos up-to-date the actual image file?

No, Photos will never alter the original image file.

You can export the photo with the GPS and reimport with file > export and activate "include location information:

Or use a tool to add location data before importing photos to Photos. I use Jetphoto Studio.

Toshiba Satellite L50 - B of the Bios date and time to reboot

Hello.
I have Toshiba Satellite L50 - B for more than a year. I upgraded the RAM to 8 GB and it works fine. But the last 10 days of the BIOS date and time keeps restarting by default whenever I turned off or in hibernation laptop. My battery is dead, but I'm not, it reloads all the time and restart the BIOS after that I have unplug the phone charger. I think that the CMOS battery is dead, but when I open the laptop there is no CMOS battery. Someone told me that this model has a kind of Flash for the time of the bios chip. How can I fix it?

Get a new battery and will be all good.

QSI CDRW/DVD SBW-242 won't read DVD or BURN a CD (music CD will PLAY) [AFTER the HD FORMAT and re - install}

Due to malware, I had to FORMAT my HD and re-install Windows XP OEM disc. I also reinstalled WIN DVD4 from the OEM disc that came with the laptop.

Check SYSTEM/DeviceMGR/material indicates a problem with the drive, but: it won't READ a DVD or burn a CD (which she has done before)

Can't update anything of QSI as they were absorbed by COREL years. No support available for WINDVD4

When you try to run WINDVD4 with a DVD in the drive, I get a Popup of WINDVD screen that says:

Response

Hello

1. are you able to read any type of file .doc or .txt of DVD?

After following all the steps (including the update of the MP9 for Media Player [MP] 11) below

I can get the drive to DISPLAY all the data from the DVD (Master & Commander 'movie)

on-screen MP11. He plays (automatically) the intro (ONLY) from the DVD music (as when you put it in a DVD player, forward to press PLAY) MP11 shows all of the content and all the files on the DVD and SEEMS ready to play, but pressing on PLAY don't either not anything.

2 , what exactly happens when you try to burn the CD? You get the error message?

Not nothing... He's here

3. How do you try to burn CDs?

MediaPlayer, selection of a track list, made a list of titles, and then click BURN... nothing happens

4 have you tried to play the DVD content in ? windows media player

I had not before, but now I have. Previously it was default to my SELECTION WIN DVD4 as the DVD player (I think I've EVER SEEN the WINDVD format/start page on the front screen - it wasn't the default front DVD player either but don't remember what program PLAYS the DVD, he ' comes of "). Now, go back and see 1. above for MP11 more details.

Try to update the drivers of CD-RW/DVD drive and check. Also update the graphics driver.

I did the entire bottom.

1. click on Start, click Control Panel, and then double-click System.

2 click on the hardware tab, and then click Device Manager.
If you are prompted for an administrator password or for confirmation, type the password, or click continue.

3 right-click on the CD-RW/DVD drive, and then select set to update driver.

He asks if I have an OEM driver and / disk... NO.. I run the program through...

"Hardware update Wiz can not find a better match the software installed"

4. right click on the graphics card and select Update driver. »

There is no "graphics card" on the material. This machine has integrated graphics using a part of the main memory (or other) to run the video section:

I find:

AUDIO, VIDEO and GAME controllers (announcement)

Audio codecs

Audio drivers

Legacy video capture device

Media control devices

Audio Sigma

Video codecs

All this seem normal but above I see YELLOW TWO warnings under 'OTHER DEVICES '.

?! Ethernet controller "drivers for this divide (code28) is not installed.

?! VIDEO CONTROLLER (VGA Compatible) I didn't HAVE NO IDEA if THIS if APPLIES OR NOT

Device type - other devices

MFG-unknown

Location PCI bus, device 0, function 0. "Drivers for this device are not installed, CODE28 to reinstall the driver."

Has been through the usual (request for drive... Laughing out loud. Impossible to beat")

How to troubleshoot common problems that occur when a Windows XP-based computer cannot read a CD or DVD

http://support.Microsoft.com/kb/321641

Did yesterday. It installed/ran "MR. Microsoft Fixit' with the result:

"Question: media in the CD-RW/DVD drive is not readable" CLICKED top DIFFICULTY... and after computer "worked" on this subject awhile, he says STATUS: fixed. St ill did not. MP9 introduced the format of the DVD player but don't seem to read anything other then showing a list:

UNKNOWN

Title 1

Title2

Title 3 etc., but could not do anything with this list.

He appeared a box asking if I wanted to update my MP9... sure why not so I shut everything down and uninstalled 9 and installed Media player 11.

Go BACK to # 1. now once again. This is where I am. MP11 shows all DVD data, the chart "the Album/DVD cover, all"titles"on the DVD, AND play the track audio 'intro' DVD but will not actually READ the DVD. "

So far it's PROGRESS. We are at a point where it SEEMS at least that we are ready to PLAY and MP can SEE all the info on the DVD.

I see many people on other sites of the same question: Player does not work after FORMAT operating system and reinstall of WIN (and in my case: WinXP SP3 and WIN DVD4 of OEM disc)

Thanks a lot for your help so far... I hope that we can get to the next step and get the reader of CD-RW/DVD on 'PLAY '.

How will I know "the size of a table special VS size of RAM"

Hi all
How will I know "the size of a table special VS size of RAM"?
I should know because I want to understand what join method to use.
Please correct me if my attempt to catch the truth is crazy.
Thanks in advance.

You can get the size of a table of DBA_SEGMENTS. I'm sure you can get the amount of RAM of other tables of data dictionary as well if you can define precisely what memory segment you are interested in (e.g. CMS?) PGA? The amount of physical RAM on the box? The size of the buffer cache? The amount of virtual memory available?)

That being said, comparing the two is not as significant. You, as a developer, are generally not in the business of choosing a join method. It's the job of the optimizer. And the optimizer takes into account a range of data that you have not begun to ask about yet. The size of the table is not even particularly relevant for calculations - the optimizer the amount of data operations are back, the relative size of the data on each side of the join, the availability of indexes, etc. are all much more important than the raw size of the table (but the raw size of the array is a factor in the assessment of the amount of data that is returned).
