Why can't create us columns name oracle 9i numbers

It gives me an error
create table tbl_testhistory
(
 1 number(20)
 )
Just curious

Hello

You can do it. It's just a lot more trouble than it's worth (for most people).

If you really, really, really want to have an identifier that is not consistent with the rules, surround it with quotation marks:

create table tbl_testhistory
(
  "1" number(20)
); 

and also surround it in quotes when using it.
Remember, what inside quotes is case sensitive, so a column named 'NOV 2010' is not the same as a named '2010 Nov»

  • Why can I download and install all Oracle ATS products for free?

    Why can I download and install all Oracle ATS products for free?  When I installed, I was invited for all licenses, or buy anything.

    I want to know why this is possible and if there are plans to charge it in the future?

    I know not exactly produced ATS of Oracle, but many Oracle products can be downloaded and used free of charge for learning purposes.

    As a general rule, if you intend to use the products in commerce, you must pay for a license, otherwise you illegally use.

  • Why can't create the dotted lines in Photoshop as easy as you can in Illustrator?

    This has been driving me crazy for a while. Why can not create a line in dotted lines in Photoshop by simply changing the race? I know you can do all that jazz with a line dotted with a brush and the spacing settings, but it's a pretty crappy solution consider if you want to change the line width, spacing of the dowry or same length, you have to start over.

    Tell me people? He is such a feature of basic of Illustrator, why can't they just add in to Photoshop in the same feature?

    Love to you all.

  • DROP table and CREATE with column name and ORA: 00904

    Hello
    I created a table with an attribute date CRTD_ON and two other attributes. Successfully created. I can see the data tab and the window empty data with column names in the header...
    Now, I had to change the name of field attribute date on OPNG_DATE so I don't bother to change, instead, I deleted and created with the name of the column has changed. Then I restart the ddl. Once again managed to create. But this time I am not able to see the data tab or the column headings. And I see the error of the log of the data Publisher ORA-00904: "CRTD_ON": invalid identifier
    Is this a bug?

    There is a current bug where you will get the data if you have a public synonym with the same table name pointing to another table with another structure. Can you confirm that in your environment?

  • How can I create a column with additional dates in number 3.6.1

    I'm a noob for Mac so be gentle with me. I have a spreadsheet and need to have additional dates in the first column of 01.01.16 at the end of the year.  I managed to create a custom date format and changed cells to be this format, but no date appears in the cells.  What did I miss? Thank you

    Here's a way to do it:

    First, make sure that your table has enough lines for all the dates you want.

    Then enter your first date is in, say, A2.  A3 (the cell below) enter the following formula: = A2 + 1

    Select the cell containing the formula, place the cursor on the lower edge, then drag the yellow point to the bottom of the column.

    You can also select the cell containing the formula, command + c to copy, select all the cells in the column and command-v to paste.

    You can, of course, always use the custom date format you like.

  • How can I create a column break?

    Hello everyone.

    I have a text box I created.  When I fill it with text, I am wanting to move to a different area of specific text on a different page of the text.  I tried to use the column break and breaking framework but had no luck with either.

    Is it possible to do so.  How can I do?

    Thank you-

    You are on the right track, but before the text goes to the next section they need be threaded.

  • Why can't I control the 'name' on my Yahoo email?

    I have two Yahoo e-mail accounts. One of them plays very well and as you when I send a message from him, it displays the name I gave you ('Bob W') as the sender when it is received by the recipient. This gives the floor VAC ' t #1.

    The other account has the problem. The problem is that when I send an email from him, he shows only the name of 'Yahoo!' or 'Y!' as being the sender when it is received by the recipient. Call this VAC ' t #2.   In addition, the "Yahoo!" is their corporate logo in purple "BOLD" and is not something that I typed in any area of settings.

    It is worth noting that I checked all settings account and I see no difference in settings between these two accounts.

    How can I get acc '#2 to perform as VAC t' t #1?

    Thank you for any help or advice.

  • Why UNION ALL allows no column names only when a literal is used and there is at least 3 parts of the query?

    An artificial union all:

    SQL> SELECT Dummy FROM Dual ORDER BY Dummy;
    
    D
    -
    X
    
    SQL> SELECT Dummy FROM Dual UNION ALL SELECT Dummy FROM Dual ORDER BY Dummy;
    
    D
    -

    D
    -
    X
    X
    X
    
    
    

    It literally changes it:

    SQL> SELECT NULL A FROM Dual ORDER BY A;

  • Why can't create shades of color from scratch (not derived from photo)?

    Hey Adobe-ers,

    I am a long-time Adobe product user, and I used the tools of color from Kuler. It is disconcerting that the mobile versions of this tool (CC color then its subsequent integration with catch CC) do not seem to give you the means to create shades of color from scratch - instead requiring an input image and picking color points.

    It seems obvious that finding inspiring colour combinations of your external environment (and take a picture of them) and derived from the color combination of your imagination, is completely different creative workflow that can the two place to the creation of assets of color. Only the former mode (probably more complex) is supported seems quite bizarre!

    I appreciate really new workflows that adobe have aroused, especially on the use of cloud storage to make simple goods to share between machines - but I'd love to have a place to create shades from scratch (in the way of the CC of color web - app) without the workaround of blocking pipeline creative to have to take a picture at random and then change the colors derived from distraction to possibly meet what I had imagined.

    PS Apologies in advance integrated;  There is a way to do and there is just something missing me, this has been answered, or if this is not the right place for feature requests etc.

    Hello Stephen,

    Thanks for that. No, you do not miss anything. This feature is only in the web version of the application. From time to time, we receive requests, to incorporate it into the app now in the mobile version, you need to capture a theme. Then change it.

    I'll leave a note for the team with your comments.

    And, just to alleviate any concerns... the right place for your comments is everywhere where it is easier for you to leave. Finally, we see (and try to respond to) everything.

    Thanks again.

  • How can I create columns of text using Dreamweaver cs6?

    Hello.  I can't create text columns.  As an experiment, I created a div with a width to 450px and 200 px in height.  After typing the first line inside the div tag, the type goes to the second line when it reaches the width of the div to 450px.  But when you type in the second line, the text continues beyond the width of the div to 450px.  When I checked to see how it appears in the browser window, the text goes beyond the viewport.  Why does that happen? And how can I make the text to stay within the width of the div?   Thank you.

    You must be typing a single string of characters without spaces.
