Hello

Something like that

SQL> create table emp_bkp as
  2  select * from emp where 1=2;

Table created.

SQL>  select * from emp_bkp;

no rows selected

or

SQL> drop table emp_bkp;

Table dropped.

SQL> create table emp_bkp
  2  as
  3  select e.empno,e.ename,e.deptno,d.dname,e.sal
  4  from emp e,dept d
  5  where e.deptno = d.deptno
  6  and
  7  1=2;

Table created.

SQL> select * from emp_bkp;

no rows selected

SQL> desc emp_bkp
 Name                                      Null?    Type
 ----------------------------------------- -------- --------------------------
 EMPNO                                              NUMBER(4)
 ENAME                                              VARCHAR2(10)
 DEPTNO                                             NUMBER(2)
 DNAME                                              VARCHAR2(14)

  • How to get the table without segment tablespace

    Hello

    I have a few tables in 11.2, which were created with creation of deferred segment and did so no segment/measure not yet. They already appear in dba_tables thus identical to the tab$, but do not have a defined tablespace.

    However, using dbms_metadata.get_ddl () the DOF resulting has the correct tablespace name. But what a view or table that I must query for this information with SQL?

    Thank you

    Robert

    Hello

    No, none of these tables is temporary, but it turns out that all the affected tables are ITO and so I have to check dba_indexes for the tablespace and the dba_indexes index_name when looking for a segment.

    Thank you

    Date1 - date2 is the exact number of days is after date2 date1. (It is as accurate as possible, given that the DATEs do not have fractions of a second).

    and one entire display i mean positive integer
    Select round ((sysdate) - to_date (date_start)), date_start days of per_periods_of_service

    You want to probably get the exact number of days first, then ROUND this number:

    SELECT  ROUND (SYSDATE - TO_DATE (date_start, ...))   AS days
    FROM    per_periods_of_service; 
    

    Always pass arguments at least 2 to TO_DATE:
    (1) the string to be converted, and
    (2) a saying string how (1) is formatted

    This gives negative also result

    Right; If date1 is before date2 then date1 - date2 returns a negative number.
    If you want to never get a negative value, use ABS (date2 - date1). If it returns 4, then you know that one of the DATEs was 4 days before the other, but you won't know who was earlier.

    I hope that answers your question.
    If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
    Explain, using specific examples, how you get these results from these data.
    Always tell what version of Oracle you are using.

    Do you mean on your Android device? Firefox for Android uses a menu drop down, or if the device has a menu button next to the home button, it uses this "hardware" button I don't think that it is possible to add a menu bar of Firefox for Android.

    If you meant on Windows:

    You can use one of the following methods to display the toolbar list and activate the menu bar it:

    To activate the menu bar, toolbar bookmarks or other bars, click it in the list.

    Who help me?

    If your Firefox does not display the toolbars, or don't shows them that when you drag the mouse to the top of the screen, try the key F11 to exit full screen mode. (The F11 key also puts you in the view full screen to the normal display mode.)

  • How to get the Application Build Date and time?

    Hi guys,.

    I am developing application in Cascade.

    What is the API I can use to get the construction Date of the application and Tiime?

    These macros are expanded to C-strings at compile time. This is how/where to use it. Following an example would work I think:

    fprintf (stderr, "construction date is %s, construction time is %s\n", __DATE__, __TIME__);

  • How to get the ORACLE_HOME without connecting to the unix Server

    Hi all!

    DOE anyone have an idea how to retrieve the ORACLE_HOME value directly from the database (connection to SQL only), without connecting to the server?
    I need to check that the solution works in all types of configurations Oracle - for example, I can find it by running:
    SQL > show spfile parameters

    VALUE OF TYPE NAME
    SPFile chain C:\ORACLE\PRODUCT\10.2.0\DB_1\DBS\SPFILERGDB. ORA
    and cut this string "C:\ORACLE\PRODUCT\10.2.0\DB_1\DBS\SPFILERGDB. ORA'-> 'C:\ORACLE\PRODUCT\10.2.0\DB_1', to get the value of ORACLE_HOME, BUT - this will not work on configurations ALL Oracle (most of them, but not all) as the DBA can change the path.

    So, you may have a better idea?

    Thank you!

    Maybe you can use something like this

  • How to get the control instance data in Bean managed when data mutiple controls exist

          ViewObject vo = am.findViewObject("ObjectView1");
    

    Hello

    I guess you have a binding method as the first activity in your stubborn workflow. Open your workflow in preview mode, right-click on your connection method and say «Go to the PageDef» This will create a definition file page for the binding of your method. You can use this to put the iterator binding that you want to access from your init method.

    Something like:

    where dt <= trunc(dt,'YYYY')+(trunc(sysdate,'DD')-(trunc(sysdate,'YYYY'))
    

    "Dt" corresponding to your date column.

    Hey thanks for the sponsor and the first off I must apologize for the State, I am attaching my VI. I put the part of the VI that I am working on (my team has access, so didn't post everything here) and also attached the data file (when just written in a spreadsheet file, not through the attached VI). I want to convert the long row of data and then start a new column every 50, 100, 5 points (user-defined).

    Using the data from the file, you can reshape everything simply (as you already!), followed by transposition (since you want columns instead of rows). 2D arrays must always be rectangular, so the last column is filled with zeros if necessary. Is that what you want?

    Of course if you try to add a new column in a file, that will not work. You can only add lines in an existing file because of the way the data is organized. To add columns, the entire file must be read, intertwined and all re-written new data in the file.

  • How can get the new button tab on the side right and right next to the most recent tab?

    Firefox has just updated and the 'new tab' button is a stand-alone icon now. I can place on the far left of my bar tabs or the far-right of my tab bar. It used to be to the right of the tabs, directly next to the tabs.

    Please give me the option to have him again as former.

    Chrome is still using the classic way, I do not understand what you people think this.

    This isn't a threat, or something but I'm saying that it hurts me terribly uncomfortable to use Firefox like this, and I prefer to use Chrome now because the new tab button adjacent to and to the right of the tabs.

    Please, I would still rather using Firefox, but not in this State. Please give me the option to return to the classic.

    Thank you.
