A curious "anomaly" with the NATURAL JOIN compared to join HER for HELP

The following query returns I expect since the HR [106 lines] schema:

Select last_name, department_name of departments who JOIN employees USE (department_id);

However, when I do the full natural join with this, I get only 32 ranks.

Select last_name, department_name of the departments of NATURAL JOIN employees;

The complete NATURAL JOIN not use department_id join on? But if not what else would it use? I just stumbled on this and am especially curious that I do not use the syntax of natural join in production but prefer instead the JOIN now.

Thank you.

The NATURAL keyword indicates that a natural join is underway. A natural join is based on all of the columns in the two tables with the same name. He selects the rows of two tables that have equal values in the corresponding columns.

    I just got a new modem (Arris SB6190) and now my Airport Extreme does not connect.  It worked fine with the previous modem (a rented one TWC).  Help!

    Always recommended to reset the airport back to settings by default and then set up again whenever you have a new modem or change your Internet Service provider.

    Turn off the new modem for at least 30 minutes. More is better.

    Perform a hard reset on the AirPort Extreme, then it turned off.

    Make sure that the Ethernet cable connects the modem to the "O" on the AirPort Extreme WAN port

    After the power of the modem 30 minutes down, turn on the modem and let it run for at least 5 minutes by itself.

    Then, turn on the airport and let it run a few minutes

    Set up AirPort Extreme again

    Important note... There are many reports of problems with the modem Arris SB and airports. Both are great products, but they do seem to work perfectly together for some users.

  • Can we synchronize permission selected with the settings of operating system Notifications BB10 for our Application.

    https://developer.BlackBerry.com/HTML5/APIs/beta/BlackBerry.notification.html#jbo1385148829097

    But it seems that this API has not been fully implemented; It may be useful to connect a developer Issue Tracker JIRA to get this feature added.

    At the same time, there is this API of Cascades that looks like what you're looking for:
    https://developer.BlackBerry.com/native/reference/Cascades/bb__platform__notificationapplicationsett...

    Write an extension for this feature should allow you to access this feature:

    At the same time, a colleague is currently working on an extension that should open many features of Qt, and I think that the API above should be accessible through this extension. He must be released over the next week or two, so you can wait for that as well.

    EDIT: On this last point, see this extension which provides a mechanism for attaching in the majority of the Qt APIs.

  • What can a left-handed user with the natural ergonomic desktop 7000?

    Hello

    I am convinced that the keyboard in the 7000 natural ergonomic office would be the best for me. However, I am left-handed, so the mouse that does not work.

    So I was wondering what Microsoft wireless solution is recommended. I don't see the keyboard available separately. So I need to get an ambidextrous mouse separated and use two USB receivers on two USB ports? Or the USB receiver that comes in this set can be programmed to operate with another mouse?

    Thanks a bunch,

    Alan

    As near as I know it, MS does not the keyboard of the "Desktop 7000' available separately.  The "natural ergonomic Keyboard 4000" MS looks like - from the site, in any case - being identical to the keyboard of the updated 7000 except that she is wired rather than wireless.

    It depends on what is important to you.  If you want the keyboard with a WiFi feature, then you will need to buy the 7000 set, take the mouse and buy a different mouse.  You can buy a standard mouse (wired or wireless), a mouse "Ambidextrous" MS (wired or wireless), or there is an ergonomic mouse for left-handers available by other sellers, for example, http://www.thehumansolution.com/left-hand-ergonomic-mice.html and Google.

    Otherwise, buy 4000 wired keyboard and mouse of your choice.

    The only downside I see to have a separate keyboard and mouse is that you need to use the two USB ports - but most people already do.  I had two (the pointer of the mouse and presentation) wireless devices connected to a laptop without any problem of interference at all.

    To answer your last question, I don't have the final answer (because I have no MS info inside), but I'm sure that you can not do anything with the transmitter/receiver that comes with a mouse without a wire and/or keyboard 99.99999%.

  • Need help with the condition join in SQL

    Hi all -

    Three questions:
    (1) I don't want to return results where table_name = "table1". I can't get this to work.
    (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.
    (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

    Any advice/suggestions are appreciated-

    Thanks for posting the CREATE TABLE and INSERT.
    It is more useful if you post the code that can be run without modification. You did not semicolons after INSERTION instructions.

    Three questions:
    (1) I don't want to return results where table_name = "table1". I can't get this to work.

    What have you tried? Post your best attempt.
    Here's one way:

    SELECT    u.table_name
    ,        u.column_name
    ,        c.constraint_name
    FROM             user_tab_col_test      u
    LEFT OUTER JOIN  all_cons_columns_test  c
                            ON    u.table_name     = c.table_name
                   AND   u.column_name     = c.column_name
                   AND   c.constraint_name IN ('primary')
    WHERE       u.table_name     = 'table1'          --  *****  NEW  *****
    ORDER BY  u.table_name
    ,            u.column_name
    ;
    

    You would not put this condition in the clause; who controls what is considered as a match between the tables, and "u LEFT OUTER JOIN c" means show all lines of u, even if they do not have a match in the c.

    (2) is my proper request and this is the best way to return my desired results? For example, I want all of the columns of user_tab_col_test and I want to only display the constraint_name from all_cons_columns_test argument if the argument constraint_name = 'primary '.

    Basically, this application is very well.
    It displays all the columns of user_tab_col_test; missing data_type. Just add u.data_type to the SELECT clause, or change the SELECT clause

    SELECT    u.*
    ,         c.constraint_name
    

    (3) will be the synatx be the same if I need to join a third table to all_cons_columns_test?

    Do you mean "" * add * one-third * column * to all_cons_columns_test '? "
    It depends on what results you want. Post new CREATE TABLE and INSERT and instructions the results you want new data.
    Most likely, the basic structure of what you've written will remain exactly the same.

  • Problem with the natural language search

    I have a document with the words "retirement payment options. When I type the question ' what are my pension options?, "I get the message"Sorry, we don't have find a good answer to your question." I tried to use synonym and synonym of directional groups pertaining to 'options of retirement', 'options of payment of retirement,' 'options' and 'payment options' together, without success. Even when I type the exact title of the document in the search box and start search, I come back with no results found.

    I want to know is how the natural language search determines what are the topics to display.

    Discovered that the problem was the updating of the .nls file. The file should be renamed and a new one created.

  • Need help with the ANSI Join syntax

    Version: 11.1.0.7

    I have my select statement that returns 3000 lines and looks like
    select ..
    from tab1 a,tab2 b,tab3 c
    where a.c1=b.c1 and
    b.c2 = c.c2(+)
    and ...
    group by
    ..
    I want to convert it to ANSI SQL, because it must be able to Hibernate, and the developer says that Hibernate include only ANSI SQL. I tried something like
    select ..
    from tab1 a INNER JOIN tab2 b
    ON a.c1=b.c1 
    LEFT OUTER JOIN tab3 c
    ON b.c2=c.c2
    where ...
    group by
    ..
    I felt bad and it turned out to be the same. It returns no rows. Please help with the correct syntax.

    I'm not sure, sorry, because it's certainly the ANSI equivalent to the non-ANSI.

    If there is no Clause WHERE conditions in the original that are included in the ANSI version of the query in the WHERE Clause for the EXTERNAL table itself joined, then that could transform the JOIN JOIN internally, that is, all the filters on the EXTERNAL joined table should be included in the JOIN predicate - IT (b.c2 = c.2 AND c.c3 = 'X').

  • How to organize a table like 'move with the text' and 'around and underneath "? For now, my only option in the menu drop-down is "in line with text.

    Hello. I am trying to format a table, so that when I hit it, it moves to the bottom of the page and the bumps any text underneath down as well (that is if you can see the whole table and all text at any time)

    .

    However, the only options I seem to have are moving with the text > inline with the text. The first part is what I want, but having the means of inline with the text of table than all text below it floats UNDER the table, and you can't read it.

    PIC 1 - My only option when "move with the text" is selected. As you can see all the other features are also grayed out.

    Photo 2 - I want now, select above and below, but when I select something other that in line with the text...

    PIC 3... it jumps to stay on the Page option is not what I want.

    Any ideas?

    You can have a floating table in v4.3 Pages ' 09 that moves before the text typed before it, but this feature has not been added to any release of v5 Pages. Simply set the table in the Wrap Pages ' 09 Inline with the text Inspector, and object causes the film if you wish.
