How long is a date?

Interesting:
CREATE TABLE date_test AS SELECT SYSDATE AS thedate FROM dual;

CREATE OR REPLACE VIEW date_test_v1 AS SELECT * FROM date_test;

CREATE OR REPLACE VIEW date_test_v2 AS SELECT SYSDATE AS thedate FROM dual;

SELECT table_name, column_name, data_type, data_length FROM user_tab_columns WHERE table_name LIKE 'DATE_TEST%';

DROP VIEW date_test_v2;

DROP VIEW date_test_v1;

DROP TABLE date_test;
Why is a date 7 bytes, unless it is a constant in a view, in which case it is 8 bytes?

According to http://download.oracle.com/docs/cd/B28359_01/server.111/b28318/datatype.htm#i1847, it should be 7 bytes.

See you soon,.

  • Data updated in cache of deleted records? How long?

    I deleted a touch of Eloqua, looking for who to contact and I saw that he had ceased to exist in the database. I then recreated this contact record by completing a form. When I looked up the contact record in Eloqua, I find it again, but with all the data that existed on the deleted contact record (salesforce ID etc.). How long Eloqua hidden registration old contact data before a new record may exist for that e-mail address?

    I received this reply from customer support:

    "When a contact is deleted, Eloqua retains the subscription status and bounceback of that contact at all times. Now as for the question regarding the repopulation of the contact data, field when you re-created your contact system read your eloqua cookie and used the data associated with your existing profile yet to repopulate the data of contact - FYI profile data related to a hard contact record about four months in the system (even after the contact has been deleted). »

  • How long the mid 2007 iMac, running El Capitan 10.11.6 rely on Apple?

    Hi all

    I was dreading the day where it would happen, but with the release of the Sierra of the OS, I see that my iMac mid 2007 is no longer able to update for Sierra. I am El Capitan 10.11.6 running without any problems and always up-to-date security, etc. I would like to know how long my iMac will be supported by Apple and for how long it will be safe to use.

    Thank you!

    It is usually 7-8 years for the material, if you are already past. I don't know what's calendar from Apple for the OS, but you're on the latest version of El Capitan and I guess they will award updates security for a little; However, since Sierra was published, the focus has shifted to who and I expect updates to security for a past OS for over a year about.

  • How long to migrate old Mac to new Mac?

    I'm migrating my old Mac to my new Mac. I'm in year of transfer stage information for 3 hours now. How long does take the migration?

    You ask a good question on migration data from an older Mac to a new. The answer, of course, is "it depends."

    Relevant issues-

    The amount of data is moved? More data takes more time for obvious reasons.

    How the two computers are connected? Wired Ethernet connections are generally faster than using a Wi - Fi connection.

    What is the speed of the network?

    That being said, I saw data transfers take more than 3 hours several times.

    Good luck.

  • My iPad will not extinguish little matter how long I press the power button.

    Why my Ipad2 refuses to turn off no matter how long press me on and press and hold the power button?

    Try a forced reboot. No data is lost during this procedure. Hold on the sleep and home buttons at the same time for about 10 seconds until the Apple logo appears on the screen. Then, rotate the unit and try to stop.

  • How long will last the iPad 2?

    How do you know when your iPad is on its way?  It's the iPad 2, using the latest OS 9.2.1.  It is slow to respond and sometimes manifests 2-3 faucets to open an application.  Also the touch screen feature takes sometimes many faucets before he answers.  Restart does not help.

    Many users here still have a lot of success with their models of iPad 2 running the latest iOS. It is almost impossible to say with certainty how long a device will last, especially without knowing all the details on how you use every day. I start with really basic troubleshooting steps and see if that helps performance.

    Here are a few basics to try that could help.

    Go to settings > Safari > clear the history and data from the Web site

    Close all applications. Press the Home button twice quickly. You will see small glimpses of your applications recently used. Drag to the left to find the application you want to close. Swipe up on the preview of the application to close.

    Force reboot the device. No data is affected by this. To force the reboot your device, press and hold the two buttons of sleep/wake and home for at least ten seconds, until you see the Apple logo.

    Another thing that can help is to reset all settings. Try this. You won't lose any data, but most of the settings of the device will have to be entered again in the settings app. Settings > general > reset > reset all settings.

    If all else fails, restore the iOS software. Backup your iPad before you restore, and then restore the backup when you are finished. If this doesn't always help, restore your iPad like new and all over again. Most bought content can be downloaded again free of charge as long as you use the same ID Apple and as long as the content is always available in the store.
