DPL does support composite index?

Hi all.

If I have a table
CREATE TABLE TABLE_1)
ID INT PRIMARY KEY,
C1 INT,
C2 INT,
C3 INT
);

How to implement the 3 queries
"Select * from table_1 where c1 = 1 and c2 = 2."
"Select * from table_1 where c2 = c3 = 3 and 2.
"Select * from table_1 where c1 = 1 and c2 = C3 = 3 and 2"?

As we know, in oracle, just create 2 composite indexes (c1, c2, c3) and (c2, c3). Then all this fact, all queries will be fast.
But HEY, I don't know cursors to join.

  • How to create composite indexes for Table Type

    Hello

    I have a file type my_rec

    Type my_rec is RECORD)
    Field1 varchar2 (100),
    VARCHAR2 (100) Field2.
    field3 varchar2 (100));

    I declare a table type

    Type my_tt is table of my_rec INDEX OF VARCHAR (200);

    Here, instead of using varchar (200) can I said anyway that the values of Field1 and Field2 is a composite index?

    Thank you
    Paddy

    Still not able to solve my problem.

    No need to simplify.
    It's just not possible.

    1 index-by must be PLS_INTEGER, directory or VARCHAR2.
    2 anchor statements cannot be used (I know this isn't what you're doing here).
    3. you can not make a kind of self-reference on one of the fields in the index.

    An alternative is to make the big collect in a collection indexed by pls_integer, then go fill another collection with varchar2 key.

  • Chrome still does support OSX 10.9.5

    Chrome still does support OSX 10.9.5?

    According to the page of the Google Chrome browser, this version of Chrome is said

    in support of Mac OS X to present 10.11.5 10.9.5. Chrome - the Google browser

    However, the questions and problems that Chrome continues to show Mac users,

    indicate that it is not a wise choice for Macs.  Users have found Chrome to be

    a resource eater, which affects the performance of OS X.

    We'll find a better browser to Mozilla Firefox; also Safari is always supported by

    Apple at the moment (my OS X 10.9.5 a recent version of Safari; I prefer Firefox.)

    A few others are probably OK, that won't cost you performance elsewhere.

  • HP J6450 really does support WPA Wireless encryption?

    I just bought a new J6450 yesterday, and when I tried to install it as a wireless network my SSID does not appear (even if the PC just next to the printer is connected to my network).  Even when you enter the SSID manually the installation process does not recognize it. There are other SSID in the region that appear during the installation.  I confirmed that my router is broadcasting and the printer was 4 feet from the router, so I know that is not due to the intensity of the signal.

    Details of router - NetGear WPN824v3, configured for either 802. 11B or 802.11 g (auto mode), WPA encryption

    The only thing I noticed during my research it tonight is the SSID that was listed when installing 2 are encrypted and most of the HP support info and documentation related to the wireless configuration seems to refer essentially to WEP.  If the HP J6450 really does support the WPA encryption, and if so, does anyone have ideas for troubleshooting why it does not recognize my router?

    Thank you.

    Connection to the router under the admin user, then "Wireless settings" page is a Mode setting and the default value is "Auto 108 Mbps.  Using the arrow in the drop-down menu, change to "b and g" then set the channel to 'Auto' and save the configuration changes.

    Hello

    These information are not known to me, and especially if you want to buy a car for you laptop, you must first call the Toshiba authorized service provider for more information on compatible players.

    There is also another possibility to find out what the laptop supports parameters.

    After this diagnostic procedure, you need to know more details about the installed drive and you must buy the player that supports the same specifications

  • Satellite L500 does support VMX?

    Hi friends,

    I am using Toshiba L500 series, I installed the 64-bit version of Centos 5.3 in my computer successfully, but I want to install another version of centos5.x in the Virtual Machine box, but it was not installed, in the middle of the installation of the Centos 5.x 32 bit it was struck, then please say one, it is very important to me...

    Thanks and greetings

    Vnvs Swamy

    > Toshiba does support VMX?
    Maybe it sounds silly now but Toshiba supports own products only. With other words Toshiba must offer support for hardware and software pre-installed.

    If you use a third party software and there is a problem, that you should contact the first software company to see what they say on this subject.
    Toshiba has nothing to do with Centos 5.3 and VM box. You can call the hotline of Toshiba and ask, but I'm 100% sure that you will get the same answer.
