Data external to appear as the date column

Hello

I have an external table that gets a column called time_stamp in the external table as varchar (I know, bad), is there a way to turn in date with the time when the external table definition? or can I have a query with the to_date function to overcome the problem?

column

14/01/2014 11:20:43

Thank you very much.

the foregoing transforms col3 in date format, but displays the following value in the external table: 14 January 14, it should be mm-dd-yyyy

Do you mean when you query the external table?

Dates (stored as DATE data type) have no "format".

If you want the string to a date column representation in a specific format, and then set your NLS settings (setting NLS_DATE_FORMAT) accordingly.

Edit:

Don't forget to change the data type in the column as well list, otherwise you will get an implicit conversion that could also explain the issue:

create table my_ext_table)

col1 number (8)

, col2 VARCHAR2 (3)

col3 date

)

(external) Organization

  • An e-mail account does not appear in the left column of Thunderbird.

    My computer (Windows XP) has two e-mail accounts and local folders that display correctly under "Accounts Mail and News" in the troubleshooting information. But Thunderbird has stopped to show one of the accounts in the left column (the directory structure) of its start page. This account was created many years ago that the messages are placed in the local folders Inbox instead of in the Inbox of the email account (Finally, I think that Thunderbird is confusing on what is meant here), but it has worked well until recently, and for this reason I can still use the email because the Inbox of local records etc. are visible. But because this email account is not on the left, there is no way to get on the right corresponding a sign "Email, accounts and advanced features". The second e-mail account (created as a test because there was this problem) is functioning normally. I tried the fix described in questions/1141037 but nothing has changed. How can I get this account to display?

    It's probably a POP-connected account and a game, like you, to use the global Inbox.

    Open the account and settings in the server settings pane, click "Advanced". He was to use the global Inbox?

    Yes; whenever you have a problem, please post a small example data (CREATE TABLE and only relevant columns, INSERT statements), so that people who want to help you can recreate the problem and test their ideas.

    Also post the results you want from this data, as well as an explanation of how you get these results from these data, with specific examples.

    Simplify the problem as much as possible.  For example, if your strings are sometimes up to 4000 characters, you don't have to display all of the data that is almost as long.  You can probably show you want with strings that are 80 characters long.

    WHERE str LIKE "%" | old_link | '%'

    ;

    will change all the occurrences of old_link to new_link.  It will only change the lines where old_link occurs, but, aside from that, regardless of how many times old_link occurs in str: if it appears 2 times in the same str, two occurrences will be changed in new_link.

    Watch out for the problem ' mother is in chemotherapy.  If old_link is 'bar.com', the above statement will change "a".  You may need to REGEXP_REPLACE or REGEXP_LIKE if you need to consider what (if any) comes immediately before "bar.com' to decide or not to change it.

  • Several flat_files through the external table with only the common columns of loading

    Hi, I have 50 flat files and each of them have some columns (fields) common and I need to load only the fields that are common to an external Table. Is any chance to do it with education unique external table. Or I need to load all flat_files at separate tables and then with the ETG and UNION load them only one table.

    If the page size for all the files are different, I think that your only option would be to define different external tables and create a view that joins all the.

  • Combine the three columns into a single

    Hello

    We have a hierarchy of dimension organization at three levels: company-> Group-> business units operating... each with a total of actual AMAURY. (Business Units drive business groups and business groups roll in society)

    I want to display the data for the amounts of the CDA in a simple table report but I need to have the name of the entity (company, group operating Business Unit) doesn't appear in the same column, only not as a hierarchy.

    Example:

    Company $1-6500
    Working Group 1-2 $500
    Business Unit 1-$1000
    Business Unit 2-$1500
    Group 2-$4000
    Business Unit 3-$3000
    Business Unit 4-$1000

    Is this possible?

    TIA,
    Ash.

    A possible solution: you have to do four-speed with two columns.

    One for the company
    One for the Business unit
    One group of operation

    And the other to a Union of the first three reports.
    And you need to add a column to sort (hierarchy pesudo) If you want to see the values in the correct order.

  • Use the 2nd column for the label data

    This should be easy. Online help for the numbers shows an example under Add graphics > adjust figure brands and labels.  My table is a simple 2-d column chart. In a single column, I have the weight in pounds, and in the second column, I have a date. When I have only the weight column selected in the form of data, I get a graph that is almost perfect, but there is no date label. When I try to include date data, I have a reverse relationship X and Y. Once I selected a cell as reference data, it doesn't have any way to deselect. What I want to do is chart weight against date and have the date appear as a label.

    Any advice is welcome.

  • Importing data (6 areas) from Excel to the address book of Tb. 6 all appear in the Contacts pane, but 3 of them are in the process of work and do not show up to above therefore impossible to sort.

    I try to import the file Excel Tbird address book data (6 fields). All the 6 fields appear in the Contacts pane, but only 3 of them appear in my list where I can sort them. I tried to add all the options for display (CAT name, organizations, etc.), but there is no data in one of these. The other 3 fields appear for each entry in the Contacts pane, but they appear below the blue bar that says 'work '. It is a zip code and the name of the city that I want to be able to sort the whole by address list.

    I guess that you export your Excel file to a comma separated file.
    Try to include the column names until the last necessary one, in the same order and spelled as an address book.
    When you export mark the part you want to use column incl. names
    Open your .csv in a texteditor, y at - it no additional space, strange letters, commas, etc.

    The best way to get all the names is to export an address book to a csv file

  • DataGrid: data based on the datagrid column headers

    I have a datagrid I want to fill the headers of datagridcolumn with specific data during execution.

    I'm going through the array of data objects and the creation of each column, but I still need to figure out how to set the header for each of them. I tried to set the itemRenderer for the column of a component simple lable, but then I don't know how to set the text of this label on the name to say correct datadriven of objects field.

    Any help would be greatly appreciated,
    Ruben

    I figured this out. Essentially before defining the its you get your component and wrap around a ClassFactory object and then set the property that you want to appear in the header. You can do this in a loop and change the header you go. Here's some code that could go in a loop:

    var lblFact:ClassFactory = new ClassFactory (Label);
    lblFact.properties = {text: "changing text data"};
    dgColumn.headerRenderer = lblFact;

    Maybe this will help someone later.

  • date does not appear in the message list

    For the many emails I get from various accounts date does not appear in the list of messages, only time.
    It seems that these messages were received today, in fact they are old.

    Encountered this problem on 2 different PCs, 3 different email (gmail and own server) accounts.

    What could be the cause and how to fix it?

    IF you select Ctrl U _ on one of these messages, there is a right of the line at the top of the message
    -Killed Mar 25 10:09 2014 is a message that I received today. This is the date and time Thunderbird has calculated, he received the message

    Lower on the list

    Date is: sub form Date: Monday, March 24, 2014 23:32:50-0000

    These two are of the same email.

    E-mail uses time GMT so that the message has been sent to 24 March 2014 23:32:50 GMT.

    Thunderbird uses my locale information to know that my timezone is GMT + 09:30 by result Mar 25 10:09

    If your seeing odd times instead of dates, check that the information is correct as above.

    Note that if the sender is their computer set to 1970 date then you will get mail today from them with the date of 1970. Even if they think it's in October that is what will show their mail. This is most important when dealing with people with limited computer skills. They do not appreciate that the date and time zone information are really relevant to them at all.

    A favorite of spammers is to use a date in the future, so their junk is at the top of your e-mail list until you actually do something with it.

    Contact your carrier and make sure that your account is configured correctly. Then go to settings/general/to comments and press the network name; This will cause the exceptional carrier updates to install (you will see a dialog box saying if an update is needed). In addition, go to settings/general/reset - Reset network settings if none of these fix. You will lose the WiFi passwords, but nothing else.
