Help with 'connect by prior' statement

I've got a quoting report that is sporadically ordering incorrectly and I've traced the source down to a 'connect by prior' statement. Can I get an explanation of what the statement is doing so I can figure out how to change it to get the desired results?
select rownum config_rownum, quote_line_id,related_quote_line_id rlid, level
from aso_line_relationships
where relationship_type_code = 'CONFIG'
connect by prior related_quote_line_id = quote_line_idsample output for the line_ids for one quote:

24          7463          7464I tried to substitute the simple query above for the 'connect by prior' query in the report but failed because something in the report is expecting input from the 'connect by prior' statement. So eliminating the statement is not a choice.

"connect by prior " is for for hierarchical queries which is for data has parent-children relationship, and ususlly its' result is used to populate tree-like data result. and order by is NOT recommend since it will destroy the hierarchical order.
you could use "order by sibiling" if you would like to order inside the same level of data

SQL with connect by prior running for a long time

Hi,
We are using Oracle 10g. Below is a cursor sql which is having performance issues. The pAccountid is being passed from the output of a different cursor. But this cursor sql is running for a long time. Could you please help me in tuning this sql. I believe the subquery with connect by prior is causing the trouble.
The TRXNS is a huge table which is not partitioned. The query is forced to use the index on the accountid of the TRXNS table.
The accountlink table has 20,000 records and the TRXNStrack table has 10,000 records in total.
This sql executes for 200,000 pAccountids and runs for more than 8 hours.

Help needed with CONNECT BY PRIOR

I need to display salesrep-manager hierarchy. I'm using the following SQL and am sure I'm doing something wrong somewhere, but just can't pinpoint. Any help is greatly appreciated.
<pre>
SELECT sf.source_name salesrep
,mgr.full_name manager
,level
FROM as_salesforce_v sf
,per_all_assignments_f pass
,per_all_people_f mgr
WHERE sf.role_name = 'Sales Representative'
AND SYSDATE BETWEEN nvl(sf.start_date_active, SYSDATE) AND
nvl(sf.end_date_active, SYSDATE)
AND SYSDATE BETWEEN nvl(pass.effective_start_date, SYSDATE) AND
nvl(pass.effective_end_date, SYSDATE)
AND SYSDATE BETWEEN nvl(mgr.effective_start_date, SYSDATE) AND
nvl(mgr.effective_end_date, SYSDATE)
CONNECT BY PRIOR mgr.person_id = pass.supervisor_id
START WITH pass.person_id = sf.employee_person_id;
</pre>
TIA
Alka.
Forgot to mention, the SQL takes forever to run.

as_salesforce_v view stores the salesrep name (as specified by the condition sf.role_name = 'Sales Representative'). This view also has rows for managers of salesreps as that's how Oracle Sales app allows the users to access the app. This table stores employee id in column employee_person_id.
per_all_assignments_f table stores the assignments for all the employees (including salesreps and that's why condition START WITH pass.person_id = sf.employee_person_id). It also stores the employee id for the manager (column supervisor_id).
per_all_people_f has all the employee records (including manager records) and the column person_id is the employee id (condition pass.supervisor_id = mgr.person_id).
Hope this explanation is helpful.

Need help with connecting file inputs to arrays

In this assignment I have a program that will do the following: display a list of names inputed by the user in reverse order, display any names that begin with M or m, and display any names with 5 or more letters. This is all done with arrays.
That was the fun part. The next part requires me to take the names from a Notepad file, them through the arrays and then output them to a second Notepad file.
Here is the original program: (view in full screen so that the code doesn't get jumbled)
import java.io.*;       //Imports the Java library
class progB                    //Defines class

        InputStreamReader reader;                                 // Allows the program to
        reader = new InputStreamReader (System.in);               // read the the keyboard
        keyboard = new BufferedReader (reader);                  //<-
        String name;                 //Assigns the name variable which will be parsed into...
        int newnames;               //...the integer variable for the amount of names.
        int order = 0;              //The integer variable that will be used to set the array size
        String[] array;             //Dynamic array (empty)
        System.out.println (" How many names do you want to input?");   //This will get the number that will later define the array
        name = keyboard.readLine ();
        newnames = Integer.parseInt (name);                                         // Converts the String into the Integer variable
        array = new String [newnames];                                               //This defines the size of the array

                System.out.println (" Please input name ");                            // gives them a number according to
                temp = keyboard.readLine ();                                           // the order they were inputed in

}The notepad file contains the following names:
jim
laruie
tim
timothy
manny
joseph
matty
amanda
I have tried various methods but the one thing that really gets me is the fact that i can't find a way to connect the names to the arrays. Opening the file with FileInputStream is easy enough but using the names and then outputing them is quite hard. (unless i'm thinking too hard and there really is a simple method)

By "connect", do you just mean you want to put the names into an array?
array[0] = "jim"
array[1] = "laruie"
and so on?
That shouldn't be difficult at all, provided you know how to open a file for reading, and how to read a line of text from it. You can just read the line of text, put it in the array position you want, until the file is exhausted. Then open a file for writing, loop through the array, and write a line.
What part of all that do you need help with?

Help with connecting to NIST NTP server on port 123

I can get NIST time in Daytime format using the rt_nist_date_time.llb example posted on ni.com, but I cannot connect to NIST NTP format time data using port 123. I freely admit to being over my head with this stuff, and have spent much of this Thanksgiving holiday reading about UDP and TCP.
The attached vi summarizes what I've tried so far. The UDP case is what I thought would work, but I can't come up with a network address that the UDP-open vi likes. Can anyone out there help this n00b tell the time?
The attached file is supposed to be in 8.0 format, although I'm working in 9.0
Here is a link discussing the time formats: http://tf.nist.gov/service/its.htm

THANK YOU!!! I don't think I ever would have come up with connecting the web address to a Read or Write UDP rather than the Open UDP block. Not to mention starting by opening port zero.
Unlike TCP, UDP is a connectionless protocol. Here's a quick explanation in different words.
A udp packet travels from a [sourceIP, sourcePort] to a [DestinationIP, destinationPort].
UDP open basically reserves a local port used for sending (soucePort) and receiving (incoming packet with that same destinationPort). Since some local ports are always in use, you would generate an error if you would accidentally pick a used port. Picking zero is useful for requests (as in this case!), because the OS will pick an unused ephemeral port. The actual source port number does not matter because the NTP server will just send the reply packet back to whatever port it came from. (If you would write your own NTP server in LabVIEW, you would of course need to set the local port to 123, and would get a conflict if another NTP server is already running on your rig). Writing an NTP server in LabVIEW would be a trivial modification to the current code, try it! . Simply listen for packets on port 123, form a response packet based on the timestamp, and send it to whatever IP/Port it came from (that info is available from udp read) and then go back to listen for new requests.).
UDP write sends a packet to the server using the above opened local port as source port. You can use the same connectionID to write to several other servers and ports, because UDP is connectionless. (TCP is connection based, so a TCP connection involves a defined source/destination pair)
UDP read listens for incoming packets from all over the world at that same local port. It is very unlikely, but theoretically possible that other UDP packets will arrive at that same port, so you could even filter to make sure to read incoming packets until they match the port and IP of the original request. The current code is somewhat vulnerable to a DOS (denial of service) attack for example as follows: Imagine the guy in the next cubicle had means of sniffing your network traffic. He could write a small program that looks for your NTP requests and then immediately starts flooding your IP with meaningless UDP packets to the sourcePort you just used. The current program only reads one packet and thus will never see the return packet from the NTP server.
UDP close frees up the local port and the computer is now no longer listening for packets on that port. Of course you could keep the port open for the duration of the program, especially if you intend to send UDP request once in a while during execution.
Makes sense?

Help with connecting a G4 with mac 9.2.2 to the internet?

I am new to mac, and I have a G4 that runs on Mac 9.2.2. I plan on upgrading to 10.4.6 (tiger), but I am unable to get it to connect to the internet. Can anyone help?

What is the specific model of your Mac? This can make a difference in some things.
You can connect via a built-in 56K modem if it has one, but it will be very slow. Much better would be to connect via broadband (such as DSL or Cable) using an external modem, either hard-wired via ethernet (usual) or via wireless if available on the machine.
Connecting via hard-wired ethernet is easy. You would need to acquire a modem that is acceptable to your ISP, or lease one from them if they make that option available. Either way, get one that connects via ethernet rather than via USB - USB on a G4 is just too slow for this purpose.
The setup for ethernet is simple in OS 9:
In the TCP/IP control panel (Apple menu > Control Panels > TCP/IP), set
Connect via -to- Ethernet
Configure -to- Using DHCP Server
And that's usually all that is needed.
Connecting via wireless, Airport in Apple's lexicon, is similar to ethernet, as far as setting up the software goes. In order to use wireless, the G4 will need to have an Airport card installed, or you can use a local transmitter which connects via ethernet to the G4. The modem would need to be connected to a receiver (base station) in order to complete the communication path with the Mac.
If you choose to go this path, someone else would need to assist you in setting up the wireless components - I've never done that.
However, if you do not now have wireless internet available, and this is going to be the only machine needing to connect to the internet, it would be much cheaper and easier to just connect the modem via wired ethernet directly to the Mac.
In either case, you will also need to set up your email account. Your email service provider should provide you with the info you need to do that - account type and password, etc. This info is entered into the Internet control panel, Email tab.
If I have misunderstood and you want to connect wirelessly directly to your ISP using something like those small transceiver type modems that many folk use with laptops, that's something else, and someone else would need to help with that.

I have an iPad 2. I recently bought the iPad camera connection kit from amazon because I heard you can connect your iPad to a music keyboard with GarageBand. I have a Yamaha motif xs 8. When I connect my keyboard with a midi USB to the iPad.. Nothing happens. Can anybody help with this, and am I missing something in order to make this work???

It worked for me no problem but I'm using an ES Rack and the dude on the video I think was using an ES. It maybe the XS is wired differently. Your best option is still getting a piece like IK Multimedia's iRig Midi. It connects from the iPad dock to actual midi cables and is way more flexible if your using multiple devices.

MSI P67A-C45 (B3) Newb needs Help with connections..

Hi all..
First time posting here, but have been in the shadows for quite a while..
Anyway, i decided to finally take the plunge, and build my own PC, and now i'm beginning to hit a few bumps.
I have a couple of questions that i would like some help with, if possible to reassure myself i may be in the right direction..
I bought THIS PSU and was hoping someone could tell me where the Blue connectors (one labelled CP and one labelled U1) Connect to?
Is it into JPWR2? And does it/do they only connect in the correct way? (Do i remove the plastic cap and attach both?
and i bought THIS VIDEO/GRAPHICS CARD and i'm guessing the RED "PCI express" and "SLI ready" connect to that somehow (Haven't opened box yet for card)
Again, wondering is there a certain way for them to connect.
Also, from my chassis, the "AC '97" and "HDA" connectors go to JAUD (I guess), does it matter which one? (I currently have "HDA" connected)
I have i5 2500k already on board. (If that makes a difference).

Do the Audio plugs go into JAUD? and does it matter which one?
Yep, connect the front panel audio to the JAUD. If you need the pin layout, it says in the manual. I would say the HDA connector is the one to connect.

Any recommendations for testing it all, before i plug it in, and press the power?
Should i (Can i) test individual parts first?
Thanks again.
Check all power connections, seating of the RAM and add-on cards, check the HSF is plugged into the fan header, and obvious things like that.
As for testing, enter the BIOS and make sure the CPU isn't running too hot. Set up the RAM with the required timings and voltage, and test with >>Memtest86<< for several hours. No point starting the Windows installation if say your RAM has errors, since it will corrupt files during the install, if it installs at all.

Problem with connect by prior

Hi,
I've table TAB_MGR:
EMPLOYEE................MANAGER
ABCD...................ABC
ABC.....................AB
AB......................A
WAXXY..Y...............WAXX
WAXX...................WA
WA.....................W
I tried this query:
select a.EMPLOYEE, b.MANAGER
from
(select EMPLOYEE, MANAGER, rownum-level rl, level lv
from TAB_MGR connect by prior MANAGER = EMPLOYEE) a,
(select EMPLOYEE, MANAGER, rownum-level rl, level lv
from TAB_MGR connect by prior MANAGER = EMPLOYEE) b
where a.lv=1 and a.rl=b.rl;
output is:
EMPLOYEE....................MANAGER
ABCD........................ABC
ABCD........................AB
ABCD........................A
ABC.........................AB
ABC.........................A
AB..........................A
WAXXYY.....................WAXX
WAXXYY.....................WA
WAXXYY.....................W
WAXX.......................WA
WAXX.......................W
WA.........................W
but I'd like to get also the level 1 of employee = MANAGER
In my case I'd like to get this output:
EMPLOYEE........................MANAGER
ABCD..........................ABCD
ABCD..........................ABC
ABCD..........................AB
ABCD..........................A
ABC...........................ABC
ABC...........................AB
ABC...........................A
AB............................AB
AB............................A
WAXXYY........................WAXXYY
WAXXYY........................WAXX
WAXXYY........................WA
WAXXYY........................W
WAXX..........................WAXX
WAXX..........................WA
WAXX..........................W
WA............................WA
WA............................W
in my query lacks:
EMPLOYEE........................MANAGER
ABCD..........................ABCD
ABC...........................ABC
AB............................AB
WAXXYY........................WAXXYY
WAXX..........................WAXX
WA............................WA
How can I get also this record in my query??
Thanks!

Hi,
I had to add two record at the table TAB_MGR, because W and A haven't manager:
New tab TAB_MGR is:
EMPLOYEE................MANAGER
ABCD...................ABC
ABC.....................AB
AB......................A
WAXXYY.................WAXX
WAXX....................WA
WA.......................W
W.........................
A..........................
I have written the query:
select a.EMPLOYEE, b.MANAGER
from
(select EMPLOYEE, MANAGER, rownum-level rl, level lv
from TAB_MGR connect by prior MANAGER = EMPLOYEE) a,
(select EMPLOYEE, MANAGER, rownum-level rl, level lv
from TAB_MGR connect by prior MANAGER = EMPLOYEE) b
where a.lv=1 and a.rl=b.rl
AND a.MANAGER IS NOT NULL
AND b.MANAGER IS NOT NULL
UNION ALL
select NVL(r.EMPLOYEE,R.MANAGER),NVL(r.EMPLOYEE,R.MANAGER)
from TAB_MGR r
connect by prior r.EMPLOYEE = r.MANAGER
group by r.EMPLOYEE,R.MANAGER;
output is:
EMPLOYEE........................MANAGER
ABCD..........................ABCD
ABCD..........................ABC
ABCD..........................AB
ABCD..........................A
ABC...........................ABC
ABC...........................AB
ABC...........................A
AB............................AB
AB............................A
A.............................A
WAXXYY........................WAXXYY
WAXXYY........................WAXX
WAXXYY........................WA
WAXXYY........................W
WAXX..........................WAXX
WAXX..........................WA
WAXX..........................W
WA............................WA
WA............................W
W............................W
It seems run correctly, but now I have another problem:
In my table TAB_MGR I have add a new column DESCRIPTION:
EMPLOYEE................MANAGER.......DESCRIPTION
A.......................................L1
AB......................A..............L2
ABC.....................AB.............L3
ABCD...................ABC.............L4
W......................................M1
WA.......................W.............M2
WAXX....................WA.............M3
WAXXYY.................WAXX.............M4
from my query I'd like to get this output:
EMPLOYEE........................MANAGER.......DESCRIPTION
ABCD...................................ABCD..............L1-L2-L3-L4
ABCD...................................ABC...............L1-L2-L3-L4
ABCD...................................AB................L1-L2-L3-L4
ABCD...................................A.................L1-L2-L3-L4
ABC....................................ABC...............L1-L2-L3
ABC....................................AB................L1-L2-L3
ABC....................................A.................L1-L2-L3
AB.....................................AB................L1-L2
AB.....................................A.................L1-L2
A......................................A.................L1
WAXXYY........................WAXXYY............M1-M2-M3-M4
WAXXYY........................WAXX..............M1-M2-M3-M4
WAXXYY........................WA................M1-M2-M3-M4
WAXXYY........................W.................M1-M2-M3-M4
WAXX..........................WAXX..............M1-M2-M3
WAXX..........................WA................M1-M2-M3
WAXX..........................W.................M1-M2-M3
WA............................WA................M1-M2
WA............................W.................M1-M2
W............................W..................M1
Have someone any idea of like completing my query?
Thanks in advance!!!!

Help with Connecting New Computer w/ WRT110

My sister just got a new laptop and has the WRT110. My brother in law passed away 3 weeks ago and he had the security passcodes.
