[8i] need help with hierarchical (connection by) query

First of all, I work in 8i.

My problem is, I get the error ORA-01437 message: cannot have join with CONNECT BY.
And the reason why I get this error because one of the criteria that I use to cut a few branches with is in another table... Is anyway to circumvent this? I tried a view online (but got the same error). I thought to use the connection by query views online and filtering off the coast of what I don't want in this way, but I don't know how to filter an entire branch...

Simplified data examples:
CREATE TABLE     bom_test
(     parent          CHAR(25)
,     component     CHAR(25)
,     qty_per          NUMBER(9,5)
);

INSERT INTO     bom_test
VALUES     ('ABC-1','101-34',10);
INSERT INTO     bom_test
VALUES     ('ABC-1','A-109-347',2);
INSERT INTO     bom_test
VALUES     ('ABC-1','ABC-100G',1);
INSERT INTO     bom_test
VALUES     ('ABC-1','1A247G01',2);
INSERT INTO     bom_test
VALUES     ('ABC-100G','70052',18);
INSERT INTO     bom_test
VALUES     ('ABC-100G','M9532-278',5);
INSERT INTO     bom_test
VALUES     ('1A247G01','X525-101',2);
INSERT INTO     bom_test
VALUES     ('1A247G01','1062-324',2);
INSERT INTO     bom_test
VALUES     ('X525-101','R245-9010',2);

CREATE TABLE     part_test
(     part_nbr     CHAR(25)
,     part_type     CHAR(1)
);

INSERT INTO     part_test
VALUES     ('ABC-1','M');
INSERT INTO     part_test
VALUES     ('101-34','P');
INSERT INTO     part_test
VALUES     ('A-109-347','P');
INSERT INTO     part_test
VALUES     ('ABC-100G','M');
INSERT INTO     part_test
VALUES     ('1A247G01','P');
INSERT INTO     part_test
VALUES     ('70052','P');
INSERT INTO     part_test
VALUES     ('M9532-278','P');
INSERT INTO     part_test
VALUES     ('X525-101','M');
INSERT INTO     part_test
VALUES     ('1062-324','P');
INSERT INTO     part_test
VALUES     ('R245-9010','P');
It's the questioning of base (with no pruning of branches):
SELECT     LEVEL
,     b.component
,     b.parent
,     b.qty_per
FROM     bom_test b
START WITH          b.parent     = 'ABC-1'
CONNECT BY PRIOR     b.component     = b.parent
The above query results:
      LEVEL COMPONENT                 PARENT                        QTY_PER
----------- ------------------------- ------------------------- -----------
      1.000 101-34                    ABC-1                          10.000
      1.000 A-109-347                 ABC-1                           2.000
      1.000 ABC-100G                  ABC-1                           1.000
      2.000 70052                     ABC-100G                       18.000
      2.000 M9532-278                 ABC-100G                        5.000
      1.000 1A247G01                  ABC-1                           2.000
      2.000 X525-101                  1A247G01                        2.000
      3.000 R245-9010                 X525-101                        2.000
      2.000 1062-324                  1A247G01                        2.000

9 rows selected.
.. .but I want to only the branches (children, grandchildren, etc.) the type of part of'm '.
for example:
      LEVEL COMPONENT                 PARENT                        QTY_PER
----------- ------------------------- ------------------------- -----------
      1.000 101-34                    ABC-1                          10.000
      1.000 A-109-347                 ABC-1                           2.000
      1.000 ABC-100G                  ABC-1                           1.000
      2.000 70052                     ABC-100G                       18.000
      2.000 M9532-278                 ABC-100G                        5.000
      1.000 1A247G01                  ABC-1                           2.000
Any suggestions?

Hello

Difficult problem!

Sorry for the false leads I posted last night.
In Oracle 8.1, you can CONNECT BY first of all, in a view online and then to join her, but you can't do the reverse.
We can change the 3 query to get the desired results by replacing the external CONNECTION BY a series of analytical functions to locate all ancestors and finally SELECT a line only if all the ancestors had part_type = am'.

It's not pretty, but it works:

SELECT       component, parent, qty_per
--,       r_num, lvl
--,       SUM (ancestor_ok)
FROM        (       -- Begin in-line view to calculate ancestor_ok
       SELECT       m.*
       ,       CASE
                  WHEN c_num < lvl
                      THEN  LAG ( part_ok
                                  , r_num - NVL ( a_pos
                                                      , 0
                                      )
                            ) OVER ( PARTITION BY  c_num
                                             ORDER BY          r_num
                                     )
              END                    AS ancestor_ok
          FROM       (     -- Begin in-line view of 'M' parts in hierarchy

                                END
                            ) OVER ( PARTITION BY  c_num
                                          ORDER BY      r_num

                         WHERE      ROWNUM     <= 10     -- Guess at maximum number of levels, or omit

ORDER BY  r_num
;

On 11 lines from the bottom, I assumed that the maximum depth of any node would be 10. If you do not higher that it should really be, or if you delete that WHEN the clause, then the query still works, it'll just be less effective.

This works for your sample data and some variations I've tried, including the case where a component has many parents. Sorry, I could not test it very carefully. Try it on some of your actual data, and let me know if there are problems.

I'll try to post a more detailed explanation later.
Basically, it works by capturing the results CONNECT BY in subquery h. Each line is identified solely by r_num, giving its place in CONNECT BY results.
In the subquery m, where most of the work takes place, it calculates the a_pos, the r_num of the ancestor of a node at a given level. That value is used in the LAG later function to see if the ancestor was part_type = am' or not. Only the lines where all the ancestors had part_type = am' are included in the final result set.

I did have the time to read the messages you and Dev published today. I'll try to do this and get back to you.

Once more remind the people responsible that the Oracle 8.1 was replaced 9 years ago. Whatever they save by not upgrading is offset by what you have to write and maintain much more complicated code, which in turn runs much, much slower than something on a more recent database.
The following works in Oracle 10 and I think it would work in Oracle 9, too:

SELECT     b.component, b.parent, b.qty_per
FROM     bom_test     b
JOIN     part_test    p     ON     b.component     = p.part_nbr
START WITH      b.parent     = 'ABC-1'
CONNECT BY     b.parent       = PRIOR b.component
     AND     PRIOR p.part_type = 'M'
;

It's 7 lines of code instead of about 65 years it takes to do the same in Oracle 8.1.

    Hello

    One way is a request to CONNECT BY Bottom-Up :

    ID CONNECT_BY_ROOT SELECT ID

    parent_id

    TEMP

    WHERE parent_id IS NOT NULL

    START WITH id NOT IN)

    SELECT parent_id

    TEMP

    WHERE parent_id IS NOT NULL

    )

    CONNECT BY id = parent_id PRIOR

    ;

    Top-Down CONNECT BY queries, where you start with the roots and then to find children, are more common, only because they are appropriate for most problems.  Queries from the bottom to the top, where you start with leaves and then will find relatives, are equally valid and work the same way.

    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 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

  • Need help with the error of connection Internet "Reset local connection adapter".

    Original title: Need help with Internet connection.

    Hi, sometimes when I go to my office (HP 2009 m) I get a message that I am not connected to the internet (although I have no problem with the connection on my IPad).  When I click on solve internet connection Windows Network Diagnostics freezes when it gets to solve problems "the local connection adapter reset."   I have to turn off my computer by unplugging and then it works normally when she returns to the top. (Sorry if my explanation is difficult to decipher, I'm not very tech savvy) This could be the cause and how to fix it?  Thanks in advance.

    Well, I expected more of a response, but I'll wing it from here: your cable goes into a modem.  This modem can be a wireless modem/router, or simply a modem cable to your computer.

    Connection problem you might start by connecting the cable into the modem.  Ensure that it is well defined.  If everything looks good, then it is possible that there is a decline in cable service before he gets to the modem.  For example, the interface side of the House can be affected by a bad connection, for example water intrusion, or poor soil.  So you may want to check into that.  Then, there is always the possibility that your cable provider has lost his momentaily of transmission, and that the modem needs to be reset.  If this happens often, you must contact the cable provider.

    Modem, your computer can be connected by cable, so you will need to check how firmly the connection is.  Then, there is always the possibility that the modem is wrong.

    But if your connection is through a wireless modem/router, your connection may have lost because of a bad signal.  Once more..., the modem/router could go wrong.

    Edit has added:

    Looking back on what you said about the Ipad, I feel that you have a wireless modem/router.  It is possible that your connection to the desktop must be after you have used the Ipad.  For example, you may need to right-click on the monitor icon in the Systray to your desktop and open your network sharing Center.  Even if you can say that you are connected to the Internet, you may not.  Then... just ... simplement cliquer click on 'connect or disconnect', then find your network connection appropriate, right click on that and select disconnect, then immediately right-click the same but select Connect.


    Will be a new connection to the Internet.

  • Need help with the data storage store, local array and network connections

    Need help with my ESXi 4.1 installation

    My hardware:

    I built a server with an Asus P6T whitebox, i7 920, 12 Gig RAM, NIC, Intel Pro1000 PT Quad, 3ware 9650SE-12ML with 8 1.5 TB SATA green in a raid 6 array gives me about 8 + TB with a spare drive all housed within a NORCO RPC-4220 4U Rackmount Server chassis.  I also have a 500 GB SATA drive which will hold the ESXi and virtual machines.

    The network includes a firewall, Netgear Prosafe FVS336G, GS724Tv of Netgear ProSafe 24 port Gigabit Managed Switch on a dhcp cable modem internet service provider.

    I also have 2 old NetGear SC101T NAS disks (4to) I want to connect to the system how some - at a later date have... data on them and want to transfer to the new storage array. I always looking into the question of whether they will work with ESXi 4.1, or I might have to only access it through Windows XP.

    My Situation:

    I have already installed ESXi 4.1 and vsphere client with no problems and it is connected to a dhcp cable internet service.  I've set up host via a dynamic DNS service name give me a static hostname on the internet.  I installed three machines to virtual OS successfully at the moment and now want to first start by creating a multimedia storage server which will use some of this new 8 TB array, then separate data storage for use with a web server small overhead storage and a backup.  It is a domestic installation.

    Help with the data store and network:

    I was doing some reading, because I'm new to this, and it looks like I'll probably want to set up my table via ESXi as a nfs disk format.  Now, the data store is usually in another physical box from what I understand, but I put my readers and ESXi all in the same box.  I'm not sure that the best way to put in place with grouped network cards, but I want to make this work.

    I understand that in ESXi 4.1 using iSCSi LUN must be less than 2 TB, but nfs - I should be able to add a bigger partition then 2 TB (for my multimedia) in nfs, right? or should I still add it separately as a separate 2 TB drives and then extend them to get the biggest space.

    Any suggestions or direct resources showing examples on how to actually add some parts of the table as data warehouses separate nfs.  I know that to go to the configuration tab, and then select Add to storage, and then select nfs. I have not my picture, but it's here that I don't know what to do because ESXi 4.1 system already has an address, should I put the same thing to the new data store array also (will it work?), and what should I use for the name of the folder and the store of data... just do something to the top.  I thought to later install Openfiler (for a multimedia storage using this table server) as a virtual machine, use the table with esxi so that I can access the same storage space with widows and linux-based systems.

    I also know I have to find a way to better use my quad nic card... put in place of virtual switches, grouping, etc HELP?

    Any direction, assistance, similar facilities to sample, suggestions or resources that would help would be great. I did a lot of hunting, but still a little confused on how to best to put in place.

    You must think of VMDK files of large databases with records of random size guest go read some data (a DLL or an INI file), maybe write some data back, then go read other data. Some files are tiny, but certain DLLs are several megabytes. It's random i/o all and heavy on the search time. IO Opsys is small random operations that are often sequential (go read data, write data, go read other data,...) so that deadlines are critical to the overall performance. That's why people say OPS are / s of reference and forget the MBs flow. The only time where you bulk transfers are when you read media (ISO files).

    Well, now forget all this. Actually the disk activity will depend on the specific applications (database? mail server? machines compiler?), but the above is true for boots, and whenever applications are idle. You should see the profile to know.

    RAID 10 is faster (and often more reliable) than RAID 5 or RAID-6 except in certain specific cases. In General RAID 10 is ideal for many random writes, since the calculation of parity for RAID-5 and - 6 adds to the overall latency between command and response - latency is cumulative if a little slow here and a little slow it adds up to a lot of overall slow synchronous especially with e/s on a network. OTOH RAID-5 and -6 can produce faster readings due to the number of heads, so you can use it for virtual machines that transfer bulk. Test. You may find that you need several different types subdashboards for best results.

    You said 3ware, they have some good grades on their site, but don't believe it. With my 9650 that I found myself with only a couple of their recommendations-, I put the (simple) table for allocation size 256 k, nr_requests at 2 x the queue_depth and use the planner date limit. I had the habit for the Ext4 file system formatted with stride and stripe-width synced to the table and used the options large_files with fewer inodes (do not use the huge_files option unless you plan to have single VMDK files in the terabyte range). Use a cache of great reading in advance.

    Virtual machines use VMDK files in all cases except raw iSCSI LUN that they treat native disks. VMDK is easier to manage - you can make a backup by copying the file, you can move it to a PC and load it into another flavour of VMware, etc. There could be some features iSCSI to your San as a transparent migration but nothing for me. NFS has less chatter of Protocol if latency lower times to complete an operation. NFS is good to read and write a block of data, that's all it boils down to.

    UPS is good, but it won't help if something inside the machine explodes (UPS does nothing if the PC power supply goes down). If the RAID card has an option for a battery backup module, so it can contain some writings in memory and may end up the disk i/o after replacing the power supply. 3ware also limits the types of caching available if help is not installed, and you get just the right numbers with the module.

    Hello gurus,

    I would really appreciate your time and effort on this application. I have the following data set.

    Reference_No---Check_Number---Check_Date---description---Invoice_Number---Invoice_Type---Paid_Amount---Vendor_Number
    1234567 11223 - 05/07/2008 -paid for cleaning- 44345563-I-* 20.00 *---19

    Please ignore '-' added for clarity

    I'm writing a paid_amount based on Reference_No, Check_Number, Payment_Date, Invoice_Number, aggregate query Invoice_Type, Vendor_Number and display description with Invoice_type 'I' when there are multiple records with the same Reference_No, Check_Number, Payment_Date, Invoice_Type, Invoice_Number, Vendor_Number. When there are no more records I want to display the respective Description.

    The query should return the following data set

    Reference_No---Check_Number---Check_Date---description---Invoice_Number---Invoice_Type---Paid_Amount---Vendor_Number
    1234567 11223 - 05/07/2008 -paid for cleaning- 44345563-I-* 10.00 *---19
