Why there is no data type that stores only date (without the part of hour)
Hi allIs there a particular reason to not have a data type that stores only date (without the time part) in ORACLE - I'm asking this because the DATE (without a time) is a type of data very frequently used in any application.
Thank you.

In fact, I was reading about the types of data...We have numbers with details. According to the argument above it is not necessary. We need only a default type NUMBER.
It depends on. Much of the work that we do, we only create just like NUMBER and don't worry precision. However for financial purposes, a clarification for the monetary values of the application can be very important.
In the same way do all the varchar2 (4000) character data type. Why we would require an option to specify the length... ?
Because you can limit the size of the string that can be stored.
I see what you're saying, but that's just the way it is. Why Oracle would need to confuse the issues by having several types of data to store the type Date and DateTime requiring an explicit or implicit conversion to be necessary, or provide an indicator of accuracy against the date where this indicator of precision would take of additional storage space on something that is already only 7 bytes.
There will be internal historical reasons why it has happened this way... but really there is no need to worry.

Why is there no DPP data for the lens EF75 - 300mm f/4 - 5.6
DPP is not given for my EF75 - 300mm f/4-5. 6 goal. Why and when?
Hi PajamaGuy!
Thanks for posting.
There is no data because the function digital optimizer DPP lens is not compatible with the goal of f/4-5. 6 EF 75-300mm. This function is not compatible with certain objectives, most of which are in our range of the L series. We do not have an estimate for if or when the DLO function may be compatible with the objective of f/4-5. 6 EF 75-300mm.

I have an iMac. Mac OSX... Version 10.5.8 I had Firefox installed for a long time and use it more often than Safari these last time. However, when I'm on the FF page where it tells you what plug-ins are very good, and which are outdated (with a warning), at the top of the page, there is a message saying that my computer "does not meet the requirements to run Firefox. And yet I have it and use it! Maybe the message actually means that I can't upgrade to the latest version? But also I don't know if I should go ahead and try to download plug-ins up to date. Any input would be greatly appreciated. Thanks in advance.

There must be a way to install 8.1 without the store?
There must be a way to install 8.1 without using the store?
I work in a small shop and we're maintenance machines of Windows 8 more every week.
The only problem is that the store has been incredibly unreliable. We kept a current to 8 machines directory and a little less than 60% of those that we have had so far this year have experienced problems getting Windows Update to work properly and to get extreme Windows 8.1 download has started and installed. My colleagues and I have spent countless hours in the workplace and on our personal time trying to find fixes for these issues
I cannot yet give a complete list of the problems that we had because there is so much to - everything from Windows update not download, 8.1 sitting at 0% for hours or even days in some cases, or the wonderfully useless screen "something happened and cannot complete the installation of Windows 8.1." I even had one of our business customers bring two and nine in the box, portable identical in design. We started the update and immediate installation. The other was sitting on our bench for three days until we could get things
We have tried everything we can to avoid these problems, but always happens on a daily basis. Please tell me there is a way for us to upgrade all Windows 8 to 8.1 machines (that's what Microsoft wants, after all, isn't?) and to do so without the store.
No there is not. Sorry, but Microsoft made the decision to release 8.1 by download from the store window and buy purchase retail only we will not have to like it, but it's the only game in town. Personally I recommend to my family and friends if they have problems to download Windows 8.1 they purchase a full retail copy and do a clean install. This also has the advantage that if you wipe your computer in the future you don't have to be bothered by all these many updates. Hope this helps and if you need another post to help and we will be happy to help you.
The above opinion is mine and mine nothing and does not necessarily reflect that of Microsoft, it's employees, or any other Member of this forum.

Why I see my data in the data pane when you use a newly created schema?
I am trying to learn Oracle DB at home. I installed Oracle DB Express 11.2 and Developer SQL 4.0.3. I can connect to the database, the communication between SQL and Oracle DB Express Developer works well.
It is probably a problem with Oracle database, but since I see it in SQL Developer, I'll ask it anyway.
If I log in the HR demo schema (in line with the developer of 2 days) and create a new table called OFFICERS with some fictional characters for the data and populate it with the data through the data for HR pane. AGENTS, I can see in the table of retail Developer SQL tab of the component data. I see the column headings for the columns I've created on the top, then the line numbers for each line that I created and the data in each row.
Now I have created my own personal schema, for example MYNAME and then connected to this schema and tried to repeat the above process. I can create the table with the columns by using the new table Wizard. But once the table exists, and I go to the tab of the Panel data on the detail of the Table, I see nothing. No column header. When I hit the insert a row button in the tab of the component data, I see a marker + 1 appear, but I have nothing to click to enter data as I did with HR. OFFICERS.
Now, if I go to the SQL worksheet for embarrassing MYNAME schema and make some INSERTs, COMMIT and a query, for example
INSERT INTO VALUES OFFICERS ('Captain', 'Smith', 'Samuel');
INSERT INTO VALUES OFFICERS ("Corvette", "Jones", "Robert");
COMMIT WORK;
SELECT * FROM PERSONS;In the query result window, I get:
RANK NAME
-------------------- ----- ------
The Captain Smith Samuel
Lieutenant-Commander Robert JonesBut if I go to the Details tab of the Table to MYNAME. OFFICERS and look at the component data, all I see is two numbers 1 and 2. No column header and no data. Just the number of rows.
Why I see data in the pane the HR data. Table tab detail OFFICERS, but I do not see the headers of column or data in the USERNAME data pane. AGENTS? I can see fine columns in the columns pane, but not data in the data pane.
I looked at all the privileges that I know look, and MYNAME has at least the same privileges as HR. Any thoughts?
Thank you in advance.

Is it possible to publish an AIR for iOS app to Apple's App Store with Flash Professional in Windows? If so, how? If not, how can I and how do I especially without using a Mac? Is this possible without having to buy another software?
You use iTunes Connect to download your application and while Mac has a much more integrated process you can just use the online version of iTunes Connect to add an application. Here is me logged into my developer account (on Windows in Chrome) using the online system, immediately after I clicked on "add a new application:
When you join the developer program, you have a huge amount of resources at your disposal. Guidelines, configurations for your apps, etc. This is where I mentioned, you will need some additional tools that do not come with Windows, such as OpenSSL. With OpenSSL, you would be able to generate the necessary certificates to "sign" your request. When you export your application from Flash you will always knock Control Panel certificate you requesting your certificate (file .p12 you generate) and your mobileprovision (created in your Apple Developer account online). You cannot export to Flash without these elements.
After using guides available for you as a developer Apple and make sure that your application complies with all its requirements, you are free to submit your control application. Apple will review your app for violations of the guideline and if all together there are anywhere from a few days to a few weeks (while crazy) for your application to be approved or refused. If you get denied that they will return the reasons why your app has failed the test. You must then resolve the problems and submit again and wait. Finally, your application is approved and you will be on the store.

Import ONLY the DATA without the firering triggers
Hi, I'm on 10.2.0.4 on windows 2008. I did a (EXPDP) Export with data a USER ly, I want to import (IMPDP) data to the user with the option TRUNCATE.
Everything looks ok before seeing that the trigger of my paintings are triggered because import no INSERTS...
There are my settings:
DUMPFILE = "DESTRUCTION_DATA.dmp"
LOGFILE = "imp_DESTRUCTION_DATA.log"
DIRECTORY = DATA_PUMP_DIR
CONTENT = DATA_ONLY
TABLE_EXISTS_ACTION = TRUNCATE
JOB_NAME = 'xxxxxx '.
What is the best way to EXPORT and IMPORT only the data of a user without when everything is triggered.
What I want to do is to update my database to test with productiomn data. I don't want to DROP the user and re-create all of its objects.
Edited by: Jpmill 2010-11-09 12:01As the destination tables have already created triggers, you must disable it manually before the impdp and allow it after.
To disable triggers, simply run the output of the following query connected as the user owner of the data:
SELECT 'ALTER TRIGGER ' || trigger_name || ' DISABLE;' FROM user_triggers;
Or do the same thing with pl/sql:
BEGIN FOR i IN (SELECT trigger_name FROM user_triggers) LOOP EXECUTE IMMEDIATE 'ALTER TRIGGER ' || i.trigger_name || ' DISABLE'; END LOOP; END; /
To allow them to return is almost the same, just change DISABLE to ACTIVATE.
The steps are:
1. disable triggers
2 - impdp
3 activate the triggersConcerning

Extract data from the table on hourly basis
Hello
I have a table that has two columns date all the hours of the base and the response time. I want to extract data from the date corresponding previous hourly basis with the response time. The data will be loaded into the table every midnight.

Windows that display only half of the disk capacity
I have a new laptop HP EliteBook with Windows 7 SP1 is installed. SSD has 500 GB, but the system is only half of the disk capacity show.
What can we do? Thank you.
CHKDSK discovered... 0 KB in bad sectors. 719099 KB in use by the system. 65536 KB occupied by the log file. 89854676 KB available on disk. 4 096 bytes in each allocation units total 60636159 the disk allocation unit. 22463669 allocation units available on disk.
Coincidentally reduce then extend the volume again?
CHKDSK is essentially a tool of file system and the capacity of the disc that you see in the Explorer disc property is actually the size of the file system rather than the physical size of the volume, the physical size of the volume is based on the head of sector, while the size of the file system is based on the number of clusters (allocation units). The file system has a total of clusters 60636159 x 4096 bytes = 248,365,707,264 bytes.
Different size according to the different tools are both correct, but the file system is not using the entire partition, you need to extend the file system with the Diskpart tool.
At a command prompt, enter the following commands:
C:\ > DISKPART
DISKPART > list Volume
DISKPART > select volume c (here, you can use the figures given by the Volume of the order list or use the actual letter of the volume, in your case 'c')DISKPART > extend filesystem
DISKPART > exit (exit Diskpart)Here is a screenshot of the procedure:
The file system extension is relatively safe, but as always you should ensure that you have a good backup of your files before doing any kind of work of system disk/partition or file.
