[10g] need help with order by hierarchical query clause

I have the following data samples:
CREATE TABLE     bill_test1
(     parent_part     CHAR(25)
,     child_part     CHAR(25)
,     line_nbr     NUMBER(5)
,     qty_per          NUMBER(9,5)
);

INSERT INTO bill_test1 VALUES ('ABC-1','ABC-10',100,1);
INSERT INTO bill_test1 VALUES ('ABC-1','ABC-20',200,2);
INSERT INTO bill_test1 VALUES ('ABC-1','ABC-30',300,3);
INSERT INTO bill_test1 VALUES ('ABC-1','HARDWARE-1',401,10);
INSERT INTO bill_test1 VALUES ('ABC-1','HARDWARE-2',402,5);
INSERT INTO bill_test1 VALUES ('ABC-10','ABC-155',100,2);
INSERT INTO bill_test1 VALUES ('ABC-10','HARDWARE-1',200,1);
INSERT INTO bill_test1 VALUES ('ABC-155','RAW-2',100,4.8);
INSERT INTO bill_test1 VALUES ('ABC-155','HARDWARE-3',200,3);
INSERT INTO bill_test1 VALUES ('ABC-20','RAW-1',100,10.2);
INSERT INTO bill_test1 VALUES ('ABC-30','RAW-3',100,3);
And the following query gives me exactly what I want, in the order I want. However, I wonder if there is a way to get this order without creating the column SEQ, given that I don't need in my results
SELECT     part_nbr
,     parent_part
,     child_part
FROM     (
     SELECT     CONNECT_BY_ROOT b.parent_part                         AS part_nbr
     ,     b.parent_part
     ,     b.child_part
     ,     SYS_CONNECT_BY_PATH(b.line_nbr,' ')                    AS seq
     FROM     bill_test1 b
     ,     dual
     CONNECT BY     parent_part     = PRIOR child_part
     )
WHERE          part_nbr     = 'ABC-1'
ORDER BY     seq
;

Results of above query, except with SEQ included in SELECT (just to show what I'm sorting off of):
PART_NBR                     PARENT_PART                  CHILD_PART                   SEQ
---------------------------- ---------------------------- ---------------------------- -----------------
ABC-1                        ABC-1                        ABC-10                        100
ABC-1                        ABC-10                       ABC-155                       100 100
ABC-1                        ABC-155                      RAW-2                         100 100 100
ABC-1                        ABC-155                      HARDWARE-3                    100 100 200
ABC-1                        ABC-10                       HARDWARE-1                    100 200
ABC-1                        ABC-1                        ABC-20                        200
ABC-1                        ABC-20                       RAW-1                         200 100
ABC-1                        ABC-1                        ABC-30                        300
ABC-1                        ABC-30                       RAW-3                         300 100

Hello

As long as there is that a single root, brothers and SŒURS of ORDER BY, you say, but you can not do in a subquery (well, you can, but usually there is no interest in a subquery). If the CONNECT BY in a subquery, there is no guarantee that the main request will preserve the hierarchical order which provides the subquery.

The query you posted does not require a query of Tahina, so you can say:

SELECT     CONNECT_BY_ROOT b.parent_part                         AS part_nbr
,     b.parent_part
,     b.child_part
--,     SYS_CONNECT_BY_PATH(b.line_nbr,' ')                    AS seq
FROM     bill_test1 b
WHERE          CONNECT_BY_ROOT b.parent_part     = 'ABC-1'
CONNECT BY     parent_part     = PRIOR child_part
ORDER SIBLINGS BY     b.line_nbr
;

I said the query you posted does not require a subquery. It also does not require double, so I guess that what you posted is a simplification of what you are really doing, and that could have a subquery. In particular, if you want to GROUP BY part_nbr, you need the subquery. We can use CONNECT_BY_ROOT expression in the WHERE clause (or, come to think of it, use a START WITH clause instead WHERE), but, for some reason, we cannot use CONNECT_BY_ROOT in a clause GROUP BY; We need to calculate CONNECT_BY_ROOT in a subquery, give it a name (like part_nbr) and Super GROUP OF this column in a query.

This requires that there is that one node root. ORDER OF brothers and SŒURS means just that: children of a common parent will appear in the order, but the root nodes, which have no parents, may not be in order.

Here's what I meant by using START WITH place WHERE:

SELECT     CONNECT_BY_ROOT b.parent_part                         AS part_nbr
,     b.parent_part
,     b.child_part
--,     SYS_CONNECT_BY_PATH(b.line_nbr,' ')                    AS seq
FROM     bill_test1 b
START WITH     b.parent_part     = 'ABC-1'
CONNECT BY     parent_part     = PRIOR child_part
ORDER SIBLINGS BY     b.line_nbr
;

This should be much more effective, because it reduces the results before waste you your time by getting their descendants.
With the help of a clause START WITH here is analogous to me sending you an email, saying "come to a meeting one my office at 03:00."
By using a WHERE clause here is similar by sending me an e-mail to all members of society, saying: "come to a meeting one my office at 3:00" and then, as people get here, tell everyone except you could go back.

Brothers and SŒURS ORDER BY was introduced in Oracle 9.

  • Need help with ordering high voltage

    Hello

    NI PCIe-6341 card is already installed. And I want to order a power supply voltage (CZE1000R) to generate the high voltage (DC). The goal is to fully control the high voltage. For example, the voltage can chang from zero to 30 kV in 5 or 10 seconds and be stable to 30 kV to 30 minutes and then go down smoothly at 20 kV in 5 minutes and finally back to zero. Could someone help me with this task? Thank you.

    Hi, apok,

    I used the 'panels-test' on 'measurement and automation explorer. And I see signals on an oscilloscope.

    Thank your for your help.

    But when I try to test the "tension cntrl.vi" it has not worked.

    On the manual, he said:

    "

    Programming with external voltage:

    Disconnect between TB1-2 and TB1 - 3 riders. Connect signal 0 - 10V between TB1-3 and TB1-6 (common)".

    This means that I need to plug TB1 - 3 and TB1 - 6 and out of the acronym to TB1-3?

    ( ) YOU "dept_list"

    DE oe_order_lines_all d où d . line_id = 143424538 ;



    The output is:


    < majorLine Line Id='143424538'>

    < itemName > 15454-TCC3-K9 = </ itemName >

    < quantity > 10 < / quantity >

    </ Service >

    < minorLine MINORLINE='143424538'>

    < itemName ItemName'15454-TCC3-K9 ='=>

    < itemName > 15454-TCC3-K9 = </ itemName >

    </ service >

    </ majorLine >

    But the production expected as below

    < majorLine Line Id="143">

    < itemName > 15454-K = </ itemName >

    < quantity > 10 < / quantity >

    < Service >

    < lineId >143424538 < / lineId >

    < itemName > 1549 = </ itemName >

    < quantity > 10 < / quantity >

    </ minorLine >

    < service >

    < lineId >143424538 < / lineId >  

    < itemName > 159= </ itemName >

    < quantity > 10 < / quantity >

    </ service >

    </ majorLine >



    So the exact structure of XML output will be like that. In the example above, I didn't add the service of minors and several minor lines.

    I need to change the code above in the format below.



    < majorLine = "123456" LineID >-> there will be only one line of Major

    < itemNamme > MajorLineItem < / itemName >

    < quantity > 2 < / quantity >

    < service > -> there may be more than one service or no service of this major axis

    < > < lineId > 123456 lineId

    < itemNamme > serviceOfmajor < / itemName >

    < quantity > 2 < / quantity >

    < / service >

    < minorLine LineID '456789' = > -> there are several minor this major line lines

    < itemNamme > first_MinorlineItem < / itemName >

    < quantity > 7 < / quantity >

    < service >-> there may be more than one or NONE of the lines of service for one minor line

    < > < lineId > 11212 lineId

    < itemNamme > First_serivceOfMinor < / itemName >

    < quantity > 2 < / quantity >      

    < / service >

    < service >-> it may be more than one service lines for a line of minor

    < > 1347657 < lineId > lineId

    < itemNamme > second_serivceOfMinor < / itemName >

    < quantity > 2 < / quantity >      

    < / service >

    < minorLine LineID = "477838" > -> there are several minor this major line lines

    < itemNamme > second_MinorlineItem < / itemName >

    < quantity > 3 < / quantity >

    < / majorLine >



    Please help me to re - write the code. I used the approach of DOM node, its very long, I'm trying to replace it. Help, please. Let me know if you have any questions.


    Thank you and best regards,

    I also have the tkprof output, but let's start with that. I have absolutely no idea where to even start looking for something to improve.

    Performance would be much better if the whole query would be executed on the remote side, but the query uses the local function eval_number as well as parts of the query are executed on the remote side and results are brought alongside local and then only filtering is performed. Try the following:

    SELECT  part_nbr,
        parent_part,
        child_part,
        eval_number ('1' || path) qty
  FROM  (
         SELECT  CONNECT_BY_ROOT b.parent_part part_nbr,
                 b.parent_part,
                 b.child_part,
                 SYS_CONNECT_BY_PATH(b.qty_per, '*') path
           FROM  (
                  SELECT  doc_nbr parent_part,
                          comp_part child_part,
                          line_nbr

    Basically, it shows how to use the CASE statement. You can change based on your actual data.

  • Need help with a self-join query

    Hello
    I have A table with the following data

    OID parent_oid
    4 of 10
    4 2
    2 2
    12 6
    6 6

    parent_oid is the parent of the oid. I would like a query that displays the final parent of the oid. The result must indicate the following

    Final parent OID
    2 of 10
    4 2
    2 2
    12 6
    6 6

    I use Oracle 10 g. I am familiar with free joins, but that alone will not do the job. Thank you!

    Hello

    You are absolutely right!

    A self-join 2-way would work for lines have no parent, or lines which are directly related to their final ancestor (such as the oid = 4), but not for what anyone further.
    A 3-way self-join would work to a level more away from the last row, but no more. That would be enough with the small set of sample data that you posted, but it won't work if you have added a new rank parent_id = 10.
    An N - way self-join would work for up to N + 1 levels, but no more.

    You need something that can go to any number of levels, such as CONNECT BY:

    SELECT     CONNECT_BY_ROOT oid     AS oid
,     parent_oid          AS final_parent
FROM     a
WHERE     CONNECT_BY_ISLEAF     = 1
CONNECT BY     oid     = PRIOR parent_oid
     AND     oid     != parent_oid
;

    On sober reflection, I think that a request from top down, as one below, would be more effective than a motion up and down, like the one above:

    SELECT     oid
,     CONNECT_BY_ROOT     parent_oid     AS final_parent
FROM     a
START WITH     parent_oid     = oid
CONNECT BY     parent_oid     = PRIOR oid
     AND     oid          != PRIOR oid

    I tried a lot of things, but cannot get rid of the lines switchport

    any help would be appreciated

    Clayton

    Another way to remove the general lines switchport is to use the option "Delete" on all VLANs currently associated.  Just like what has been done for the vlan 1 in your example. Something like this:

    switchport vlan allowed General remove 153, 154

    Make sure you have the mode set correctly.  By default, the access mode is set.  If the default value of access is being used, the lines "switchport general" are ignored anyway.

    Hope this has been helpful.

  • Need help with network home using Airport extreme

    I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

    Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

    My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

    Any help you can provide would be great.

    I would like to get the return tech to help you to...

    But it is likely that something (or someone) has tampered with the settings.

    The layout is fine... but you can cause problems with the network by creating a loop.

    This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

    Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

    Unplug the two AE you have that function as extensions...

    Turning off everything else... then it works again...

    Do it in this order.

    Modem... Wait 2 min

    AE... Wait 2 min

    Switch.

    Now check that the network is working properly... power of customers in various locations and make sure everything is good.

    If so, then manually reset the two AE of factory and redo their installation.

    Follow these steps to try to solve your problems of boot.

     

     

    Restore point:

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

    Click Start > programs > Accessories > system tools > system restore > choose another time > next > etc.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

     

    If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

    Download the ISO on the link provided and make a record of repair time it starts.

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

    When you have changed that, insert the Bootable disk you did in the drive and reboot.

    Link above shows what the process looks like and a manual, it load the repair options.

    NeoSmart containing the content of the Windows Vista DVD 'Recovery Centre', as we refer to him. It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC. Technically, we could re-create this installation with downloadable media media freely from Microsoft (namely the Microsoft WAIK, several gigabyte download); but it is pretty darn decent of Microsoft to present Windows users who might not be able to create such a thing on their own.

    Read all the info on the website on how to create and use:

    http://NeoSmart.net/blog/2008/Windows-Vista-recovery-disc-download/

    ISO Burner:http://www.snapfiles.com/get/active-isoburner.html

    It's a very good Vista startup repair disk.

    You can do a system restart tool, system, etc it restore.

    It is NOT a disc of resettlement.

    And the 32-bit is what normally comes on a computer, unless 64-bit.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Data recovery:

    1. slave of your hard drive in another computer and read/save your data out there.

    2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

    3 Alternatively, use Knoppix Live CD to recover data:

    http://www.Knopper.NET/Knoppix/index-en.html

    Download/save the file Knoppix Live CD ISO above.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    http://isorecorder.alexfeinman.com/isorecorder.htm

    Download the Vista software from the link above.

    After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

    Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

    Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1st in the boot order.

    Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

    When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

    Click on the icons of hard drive to open and to understand which drive is which.

    Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

    Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

    See you soon.
