Joiner and Set Operations

I have a situation where source table A contains 3 code columns. The descriptions for the codes are contained in 3 different reference (lookup) tables. I want to denormalize target table B to include the descriptions for the 3 codes (as well as all columns from source table A).
How do I design the mapping to include reference (lookup) tables code descriptions?

You can use the key lookup mapping operator to get the values from the lookup tables on the fly. I.e. draw a connection from the source 'code' column to the key lookup operator, configure the key lookup operator to point to the appropriate lookup table with the correct lookup condition and connect the output of the key lookup to the name/description target column. The same 'code' column that you connected to the key lookup, you can now also directly connect to the code column in the target table.

LabVIEW and Set Operations

Hello all,
I am a student at the University of Texas @ Austin and I have been
looking through the LV 5.0 documentation for any documentation about
Sets and/or Operations on Sets but cannot find anything usefull. Does
anyone know if LV supports Sets and operations on Sets, for example,
Union, Intersection, or just a way to specify the elements of a Set? I
have an assignment to create a Non-Deterministic Finite State Machine
Simulator and would like to implement it using LV? I have some ideas on
how to Fake the set operations but it would be much easier to not have
to re-invent the wheel. I will check the newsgroup, but please also
respond to [email protected]
Thanx in advance Jeffo ....

There are probably a number of ways to implement this in LabVIEW, depending
upon what kind of data you want in your sets, what kind of operations you
want to perform on them, etc. It's a pretty open-ended question without
more detailed knowledge of what you're after.
From my point of view, the LabVIEW array structure and its operators are a
construct that provides some set-like functionality right away:
specify set elements => array control on panel
check for membership => Search 1D Array
set union => Build Array (followed by Sort 1D Array if you want to keep the
set sorted)
set intersection
=> loop through one array using Search 1D Array on the
other to generate output set
This is one simple approach that shouldn't require a whole lot of coding or
wheel reinvention...

Set operator Vs Self join

hi all,
i have a main table and a corresponding history table.
Like employee and h_employee both has primary key as emp_id.
now i want a query which should only retrieve the common values among these two table.
I have an idea of doing this in two way 1.self join 2. set operator
1.select emp_id
from emp e,h_emp h
using (emp_id)
2. select emp_id from emp
intersect
select emp_id from h_emp
now guide me which gives better performance? how to evaluate the performance in PL/SQL Developer client?
is there any keyword to trace the timing of the each query?
Please advice.
Regards,
Slu

Set operators combines the output of 2 or more queries into single output....
Internally its doing sorting the two tables
Join is just matching the records based on the where condition ....
use Explain plan to the cost of the query
SQL> Explain plan for select emp_id
from emp e,h_emp h
using (emp_id)
and use
SQL > select * from plan_table
to see the cost...

Out of scope error while attaching the attribute set and the operating unit

Hi,
Am getting the out of scope error when am trying to attach the attribute set "/oracle/apps/fnd/attributesets/HrOperatingUnits/OperatingUnitName_Transient"
and the operating unit lov "/oracle/apps/fnd/multiorg/lov/webui/OperatingUnitsLovRN" from my page in JDeveloper.
Can anyone help?
Thanks

Mostly
It would just be a warning message you can proceed with it there are no issues.But if its an error please do as mentioned by Reetesh.

Set operations & tables with different columns

I have a problem. I have 3 tables - Countries, Locations & Departments. I want to output the country_id and country_name from the countries tables for countries that have no departments. Locations has country_id and location_id columns and departments has location_id and department_id columns. All is in Database 11g. I can produce a table which gives me the locations with departments or without departments as follows:
select location_id from locations intersect select location_id from departments;
This gives me a list of locations with departments. Conversely I can get a list of locations without departments as follows:
select location_id from locations minus select location_id from departments;
However, to combine this output with the countries table I need to produce country_id in the output. However, when I try to add country_id to my code from above as follows:
select country_id, location_id from locations intersect select to_char(null), location_id from departments;
I get no rows found. I understand why. There is no intersection between country_id in locations and the null output from departments (where there is no country_id column). Alternatively, if I try as follow:
select country_id, location_id from locations minus select to_char(null), location_id from departments;
I get rows with every country_id whether they have departments or not. Again, I understand why. I am essentially subtracting nothing (the to_char(null) from departments) from the country_id column in locations and getting the entire country_id column as output.
How can I use set operations to produce the country_id column? I also do not want to show the location_id problem.
This problem is repeated when I try for the final country_id, country_name final output. The countries table has these columns. However, the locations table does not have the country_name column. It only has the country_id column. So a query such as this one:
select country_id, country_name from countries intersect country_id, to_char(null) from locations;
presents me with the same problem as above. The country_id column intersects nicely, but the country_name file does not intersect as it does not exist in the locations table. Again, how can I use set operations to produce the country_id and country_name columns.

Hi,
the method I outlined for you above should be fine. It doesn't matter that there are one-to-many relationships which may cause repeated output rows; set operations (except for UNION ALL ) always return distinct rows.
Can you do a query on the countries table, that shows all countries?
Can you do a query involving all 3 tables inner-joined, that shows the countries that are related to locations and departments? (Repeated rows are okay.)
Then you can do a MINUS, to get only the countries that are not related to departments.
If you get stuck, post a little sample data (CREATE TABLE and INSERT statements), the results you want from tha data, your best attemptat a query, and a description of the problem (including the full error message, if any).

Mapping - split followed by set operation

Hi I'm trying to set up a mapping to use as part of testing my warehouse and need some help.
Overview
======
I have a number of different databases that combine through to my operational data store. One verification of our mappings is a simple check of record counts, source table vs target.
Because table names differ between source and target I have loaded (from a flat file) a translation table that maps one table name to another.
I have external SQL scripts that run on a scheduled basis to capture table names, record counts and date of last update from the system tables of four of my source databases and my target database. (soon I'll need to try and replace these with OWB scripts)
I am trying to build a mapping to conform these so I end up with a single fact listing target table, record count, update date, source table, source environment, record count, update date.
I have taken my statistics on the target database, outer Joined it to the translation table (not all target tables have matching translation table records)
Then split the result set by target environment (and remainder)
Then I join each result set to the statistics for the appropriate source.
Next I am using a set operation to union all the results back to my conformed result.
My Problem
=========
Those tables in the target database that do not correspond to a table in one of the four sources cause a problem. (they are either summary facts, flat files loaded or sourced from other databases I have not got statistics on yet)
I cant just link from the splits output set to the set operation because the other joins have added extra fields for number of records in the source. The documentation is very clear that the same fields must exist in the same order and datatype.
I have been trying to work out which mapping operation/s will produce the equivalent of SQL like select col1, col2, null, sysdate, null from mytable
Hmm as I type this up I think another alternative may be to output extra fields in the split (so it looks like the dataset after the join) but not to pass these fields on in the join for sets for specific environments. Ill try that alternative but would still like help with which mapping operator I could have used.

Can I have a little bit more technical information : A small exmaple would be very helpful.

Hash semi join and join selectivity

Hi,
I'm looking for an explanation of the rule-of-thumb that hash joins are more efficient for high selectivity joins.
If I have a query with two tables, semi-joined together using an EXISTS clause, why would a hash join be better for a high selectivity join as opposed to a low selectivity join?
To clarify, my definition of selectivity is:
selectivity = # of rows returned / # of rows processed
Or in more database specific terms:
selectivity = num_rows/cardinality
Selectivity is a value between 0 and 1, so by high selectivity, I mean a selectivity value closer to 1.
Thanks for any input.

the question is "more efficient" than ... what?
A hash join is usually the most efficient operation if you have to join a large set or two large sets. Often the hash join operation performs full table scans as part of the join operation, but not necessarily.
The cost of the hash join depends on the volume to join, the available memory and the resulting operation (optimal / one-pass / multi-pass). If the hash table can be kept in memory then it's simply the cost to read the first data set used as hash table, the cost of reading the probe table and the CPU cost of processing the hash join. If the hash table doesn't fit into memory, it depends on how often the build (hash) table and probe data needs to be read (one-pass / multi-pass) to perform the join with the hash table.
If you have a "low selectivity" join, and I assume you mean that the join actually filters out many rows by "low selectivity", then other join operations might be more effective, like a NESTED LOOP that uses the smaller table to iterate via an index access over the second table, selectively picking the rows corresponding to the first table. Depending on the number of iterations and the number of rows of the second table to process per iteration this can be very efficient, but tends to be very inefficient if the iterations and/or number of rows in second table is significantly larger than estimated.

Set operations usecase

hi,
I am a new bee and would like to understand the use of SET operations ( UNION, UNIONALL, MINUS, INTERSECTION) can't we do the same with the use of JOINS ? Am I wrong ? please correct me....and few examples where there is no alternate except using SET operations will help me to understand the thing more clearly...
Thanks and regards

Output a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE   LIKE SFLIGHT-FLDATE,
      CARRID LIKE SFLIGHT-CARRID,
      CONNID LIKE SFLIGHT-CONNID.
SELECT FCARRID FCONNID F~FLDATE
    INTO (CARRID, CONNID, DATE)
    FROM SFLIGHT AS F INNER JOIN SPFLI AS P
           ON FCARRID = PCARRID AND
              FCONNID = PCONNID

      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
If there are columns with the same name in both tables, you must distinguish between them by prefixing the field descriptor with the table name or a table alias.
Note
In order to determine the result of a SELECT command where the FROM clause contains a join, the database system first creates a temporary table containing the lines that meet the ON condition. The WHERE condition is then applied to the temporary table. It does not matter in an inner join whether the condition is in the ON or WHEREclause. The following example returns the same solution as the previous one.
Example
Output of a list of all flights from Frankfurt to New York between September 10th and 20th, 2001 that are not sold out:
DATA: DATE   LIKE SFLIGHT-FLDATE,
      CARRID LIKE SFLIGHT-CARRID,

      AND FSEATSOCC < FSEATSMAX.
WRITE: / DATE, CARRID, CONNID.
ENDSELECT.
Note
Since not all of the database systems supported by SAP use the standard syntax for ON conditions, the syntax has been restricted. It only allows those joins that produce the same results on all of the supported database systems:
Only a table or view may appear to the right of the JOIN operator, not another join expression.
Only AND is possible in the ON condition as a logical operator.
Each comparison in the ON condition must contain a field from the right-hand table.
If an outer join occurs in the FROM clause, all the ON conditions must contain at least one "real" JOIN condition (a condition that contains a field from tabref1 amd a field from tabref2.
Note
In some cases, '*' may be specified in the SELECT clause, and an internal table or work area is entered into the INTO clause (instead of a list of fields). If so, the fields are written to the target area from left to right in the order in which the tables appear in the FROM clause, according to the structure of each table work area. There can then be gaps between table work areas if you use an Alignment Request. For this reason, you should define the target work area with reference to the types of the database tables, not simply by counting the total number of fields. For an example, see below:
Variant 3
... FROM tabref1 LEFT [OUTER] JOIN tabref2 ON cond
Effect
Selects the data from the transparent database tables and/or views specified in tabref1 and tabref2. tabref1 und tabref2 both have either the same form as in variant 1 or are themselves join expressions. The keyword OUTER can be omitted. The database tables or views specified in tabref1 and tabref2 must be recognized by the ABAP-Dictionary.
In order to determine the result of a SELECT command where the FROM clause contains a left outer join, the database system creates a temporary table containing the lines that meet the ON condition. The remaining fields from the left-hand table (tabref1) are then added to this table, and their corresponding fields from the right-hand table are filled with ZERO values. The system then applies the WHERE condition to the table.
Left outer join between table 1 and table 2 where column D in both tables set the join condition:
Table 1                      Table 2

Problem in Adhoc Query's set operation functionality.

Hi Experts,
I am facing problem executing Adhoc Query's set operation functionality.
In Selection Tab, following operations are performed :-
Execute a query and mark it as 'Set A'.(Say Hit list = X)
Execute another query and mark it as 'Set B'.(Say Hit list = Y)
In Set operation Tab, following operations are performed :-:-
Carry out an Operations 'Set A minus Set B'.
which results in Resulting Set = Z.
Transfer the resulting set 'in hit list' and press the copy resulting set button.
In Selection Tab, Hit list is populated with Z.
And when output button is pressed, I get to see 'Y' list and not 'Z' list.
Kindly help.
Thanks.

Set operations in AdHoc Query - user settings

Hi
I am checking out the Set operations in AdHoc Query. The documentation says you should save the setting "Set operations shown" as a user setting. Could anyone advise me where this is set? I can't find a parameter for it, and can't find it in the regular settings.
Any help appreciated.
Kirsten

The save is automatic upon exiting Ad Hoc query. Once you do "Show Set Operations", work on a query, save and exit, the next time you open Ad Hoc query, Set Operations tab is displayed by default.

Using join and batch reading in the same query

Hi,
I wonder if it is possible to use "Joining" and "batch reading" in the same query.
For example I Have
A -> 1-1 B
A -> 1-1 B
B -> 1-M C
This is the case where I have two separate 1-1 relationships to the same class B from A. Toplink 10.0.3 can manage it nicely through joining.
Now, I would like to read a set of As (with its 2 Bs) and all Cs for each B.
It seems that the following configuration does not work:
A -> 1-1 B (use joining)
A -> 1-1 B (use joining)
B -> 1-M C (Batch read)
Any help would be greatly appreciated
Tony.

James,
Would you be so kind to look at the following code?
Am I formulating it correctly to achieve my desired behavior?
Trip.class -> 1-1 PickupStop
Trip.class -> 1-1 DropoffStop
PickupStop and DropoffStop extend Stop and use same table (STOP)
Stop -> 1-M StopEvents
I would like to fetch all Trips, with their Stops and all StopEvents in 2 queries:
1. Trip joined with Stop
2. Batchread StopEvents
Code:
ReadAllQuery raq = new ReadAllQuery(Trip.class);
Expression qexp1 = new ExpressionBuilder();
Expression qexp2 = new ExpressionBuilder();
raq.addJoinedAttribute("pickupStop");
raq.addJoinedAttribute("dropoffStop");
raq.addBatchReadAttribute(qexp1.get("pickupStop").get("vStopEvents"));
raq.addBatchReadAttribute(qexp2.get("dropoffStop").get("vStopEvents"));

Airport Express (Model with 802.11G +54MBPS Mac/PC and Set Up Issues

Hi,
We have a 4 Mac and 1 PC Household. Cable Internet Service by Roadrunner.Cable model (owned) connected to a D-Link 802.11G wi fi router (by ethernet from cable modem)in the family room , then out to a Imac (the half moon base and LCD screen with a airport card also in the family room and the closet computer to the D-Link
router, (we did add a D-Link antenna to the router ? about 10 months ago (a D-Link ANT24-0700 (Version 1.2)and a HP 4 in 1 printer attached via USB to the Imac
,a eMac 1.25 ghz 1Gb ram with airpot card also connected wirelessly (no printer attached on the same floor but in a ajoinging room about 20 feet from the Router, and another eMac 1.0 Ghz 1Gb ram with airport card in the upstairs part of our house (a bedroom) and no issue with Internet connection (it has a Epson 3in 1 printer attached via USB, and a MacBook Pro with 802.11N wireless card in side , bought for a Christmas/Birthday Present and also for college.It to has no issues with the Internet where ever it may be in the house. Our sole PC a HP tower with a added D-Link WDA -2320 Range Booster Desktop Adapter (802.11G) and we added a D-Link Antenna same model as the other a ANT24-0700 to help with Internet access which it did as well as adding some ram to increase page loading time etc. It does not have a printer attached. I will get to the Topic Area now
The Airport Express. I was not involved in the set-up as I was laid up due to a bad back and post major knee surgery , But I always (especially recently) wondered why the light was amber and blinking. I read through the manual and also
Apple.com support and MacFixit.com (which is under construction and moved to part of Cnet.com)and then went to the Airport Express Discussion area (sorry for being so wordy) I need a Twitter account to post!) We have a network name for the D-Link and the computers all were added and it also supports a Xbox 360, a Sony PlayStation 3 and a Nintendo Wi (in online use without issue) but..
A network was also as it appears to myself) for the Airport Express and under the half moon bars showing connection strenght (there is our D-Link network "phoenix" with security protection WPA2 I believe) as I have set up the router, We had a Apple Base station prior that was ? 802.11B (a half moon white unit) still have it in the box ) So for normal daily use, checking e-mail and internet use all of the computers use the "phoenix" or D-Link supported Router 802.11G
and The other network calld Apple Network with numbers and letters after it (and hopefully security) password is unknown , The Airport Express is set up connected via USB to a HP B&W laser printer which has saved quite a bit of money on ink, To utilize that printer you must switch from "phoenix" The D-Link router network to the Apple Network (followed by letters and numbers) The Imac and the eMac in the family room and a ajoing room (after switching to the Apple Network
can than print to the lasr printer. The eMac upstairs and the HP Windows XP Professional software can not print to the laser printer (yet the HP PC shows it as a individual network and a strong signal, equal to the Internet connection from the D-Link, and the eMac (after switching under the half moon (not the proper name I am sure) to get to the Apple Network to print , it will not print, yet it shows a 5 bar signal, same as the D-Link connection. I do believe we have two seperate networks (but do not understand why the two Mac's in the family room can print to the laser printer by simply switching networks and then file and print. ** One other 9probaly major item is that it states to set up the Airport Express with a Mac With OSX 10.4 or later (at the time of set up, we had the Imac and two eMac's all running Panther OSX 10.3.9 9which they continue to have installed) We obtained the HP Tower and Monitor and HP 4in 1 printer ust before Christmas in 2008 and the MacBook Pro in Mid December 2009 (current model and running Snow Leopard 10.6. The HP Tower runs Windows Xp Professional (Service Pack 3) so the MacBook Pro which is much more mobile , could be used to do the set-up, or the HP Tower coulf be moved temprarily, I do recall if Router changes (at least with The D-Link You need to be connected by Ethernet to the Mac
that would be doing the set up/configuration of the router (and it runs OSX 10.3.9 and is a older Mac (with 80Gb Hard drive that is partioned for OS9 and OSX as well , it is under a Ghz processor wise and less than 1 Gb of ram as the last ram slot required a seal to be broken and 256mb of ram (?) could be added
it has 768 mb of ram but knock on wood running well. We use Lacie external drives
on the Imac and both eMac's and need to get external drives for the HP PC as well as the Mac Book Pro (15" screen)
I apoogize if I repeated myself, and rambled but I wanted to (in one post) to explain our set up and network configuration
Questions
1) if indeed it is that the two networks is true and a set yp that is not correct
can the Airport Express be configured without opening up the router (when ever that happens it seems one computer is unable to get online and each time its a differnt one a Mac or veen the PC
The PC under My Computer and Networks clearly shows the wto distinct and seperate netwoks with strong signals and the distance is not far (it is through a floor as the other emac and the PC are upstairs and cabling by ethernet is not a option
2) If I need to open the router would I add the Airport Express as a client as if it was one of the computers or gaming systems on the network? (adding the Mac adress or IP address (not sure how you find the Mac address) and its been while since the router was opened up for any additions or work on it.
3) would it be on the same channel as the router or not ?
4) Hopefully with proper configuration the light will stay on (and green) on the A/E and the eMac and HP PC will be able to print to the laser printer. Currentlt
when anything needs printed from the PC its put on a Flasg Drive and plugged in tothe Imac and the the Apple Network is selected and data printed, The eMac upstairs has the option of using the attached Epson 3 in one or doing the Flash stick work around.
I would be verya appreciative if some one took a look at the set up above and advised me of what is right, what is not right* and what to do to fix things up
I would imagine after proper set up, delete the Apple Network from the PC and eMac upstairs and ? all of the computers as we should have one base station (the D-link and the spoke (the A/E connected by UBS to the A/E (it may be ethernet but the cable connection from the A/E to the HP laser printer is correct (the rest of the A/E set up ... Please , tell me where it is and where it should be
and ? any idea why we can print to the laser printer down stairs and not up stairs ? it did mention printer set up with Panther as possible, page 43 of themanual we have un chaper 5 Tips and Troubleshooting (under whn your printer isn't responding) (we do not have the interfereance listed in the manual,
our phones are land line, one 900 mghz and the others 5.8 ghz
It is possible to move the A/E and laser printer if that would help the two computers (desktops) upstairs) bt the distance is way less than 150 but their is a floor and ? duct work (metal ) but I think here is a place to stop typing and let some of the experts on the discussion forums take a look.
one lst note (as the lap top will be going off to college in the fall (runnning Snow Leopard, and the other 3 Mac's run Panther OSX 10.3.9 should the HP PC windows Xp Professional be the computer to set up the air port express and the Airport Utility proram installed & would this conflict with the current Router (set up by a Macc running OSX 10.3.9 (Panther) i.e (should both set ups be on the same computer?) but actually aThe D-Link is OSX10.3.9 compatible (and 802.11G) and set up requires ethernet connection to a Mac (You type in the numbers and . etc and password as administror and you are in, or should the admin be on the same cpmpuer for the router and A/E ?
(and considering a Airport Extreme Base Station as well as dual frequency simulataneus and 802.11N (for the laptop now) and future, or wait. The 802.11
in theory would broadcast farther..?? even if computers had 802.11b(our Mac Desk tops and the PC 802.11B card
Thanks Again!!!
Many, Many Thanks

Hello again,
D-Link Router is model DGL-4300 (along with a D-Link ANT24-0700 Omnidirectional
7dbi Antenna . Our Cable Internet ISP (Roadrunner) provides consumers with dynamic ISP address's . All Mac's have Airport Cards and The Hp Tower XW4550 has a D-Link Rangebooster G Desktop Adapter WDA-2320 (also with a D-Link ANT24-0700 Omnidirectional 7 dbi Antenna (the PC OS is Win XP Pro Service Pack 3) The 3 desktop Mac's run OSX Panther 10.3.9 , The 15" MacBook Pro OS is OSX 10.6 Snow
Leopard (not sure what is after the .6 (right now) D-Link's website is
http://www.dlink.com , I have configured this router multiple times in the past.
also added as clients on the network (Utilizing the D-Link Router) are a X-Box 360, Sony Play Station PS3, and a Nintendo Wii all of which have on line ability
and enables online video game play with any one online.
As mentioned prior the Airport Port Express is Model A1084 Part No. M9447OLL/A
which is USB conected to a HP LaseJet B&W , model 1020 and some how the two computers near it can switch to the Airport Express Network from the D-Link Router based Network and print wirelessly to the A/E connected LaserJetPrinter
I realize I will need to reconfigure the D-Link Router and add the A/E as a client. I will try first to use the Airport Utility and see if I can do anything
Utilizing it (adding it to the D-Link network, I think its unlikely but worth a try but* the password is unknown but I have a few guess's as to what it may be.
I do have the necessary admin and network paswwords to cconfigure the D-Link Router,
1) * If the the A/E Utility experiment fails and I need to re-configure the router * do I need to (as per the Airport Express Set Up Guide (Use a Mac with OSX 10.4 or later or a PC with Win Xp Home or Professional (have a desk top PC that has the specs) and The Mac Book Pro meets the Mac Spec's)
If I can not get a password to work on the A/E I would reset it using the reset button
And before plugging in the A/E , connect the appropraite cables in our case a USB cable to the LaserJet Printer then plug in the A/E
2) I would then connect by Ethernet from Either the Mac Laptop or The PC to the D-Link router (if not the router will not set-up correctly)
3) The one question that puzzles me is that we are not using the A/E as a base
but a client
in two sections(Using Airport Express , connecting a Printer via USB
and use Airprt Utility to create a new network or join a new newWireless computers using Mac OSX 10.2.7 (Tiger) or later or a PC with Windows XP and it then goes in to the steps of ising the printer for both a Mac and a PC (using Bonjour on the CD that came with the A/E (this appears to contradict needing to use Mac OSx 10.4 or a PC with Win Xp set the A/E up for use as a printer
(joiing a new network or existig one)
And in Chapter 5 Tips and Roubleshooting= Your Airport Express Status Light Flashes amber & Your Printer is not responding (it is flashing amber and the printer does not respond to the two computers upsstairs (one Mac running OSX 10.3.9 & One PC running WinXp and its states to make sure the printer is selected
in the Printer list o client computers, to do this on a Mac using OSX 10.3 or later , open Printer Set Up Utility and follow steps and if a PC with Windows XP , Open Printers and faxes and then follow steps
in Closing ? can I configure the A/E Utility with a Mac using 10.3.9 as above or
? Per Chapter 1 Getting Started use a Mac with OSX 10.4 or later or a PC with Windows Xp Home or Professional
Perhaps I am taking the tips and trouble shooting and Printer Set up out of context or does the getting Started Computer specs contradict them or are they
for use if the A/E was going to be a Base Station and not a client..
Will keep at it,

My home wifi is available at full bars on the settings menu, but when selected it says it cannot be joined, and when it does connect, it only lasts a few seconds before disconnecting. My laptop connects to the wifi perfectly fine though. Help?

When in the Wi-Fi menu under settings, my iPod five will display the different wifi networks in range, including my home wifi network. The shown network has full bars and my laptop will connect to the network with no trouble. When the wifi on my ipod is selected though, it will show it is loading to connect, it will actually connect for five-ten or sometimes twenty seconds, and then it will disconnect. The wifi never automatically connects on my iPod5. It always has to be done manually and then does not establish a complete connection. No matter where I stand in the house, even if it is right beside the router, this happens. Sometimes when the network is chosen it refuses to connect and gives the message "Unable to Join". I've had it for a year and a half and for about the first six months it never had this problem. But then it began, and it would go through monthly cycles of working perfectly and doing what it is doing now. As of now I haven't been able to connect for three months. I'd like to think it's simply the wifi itself but mine and my sibling's laptops will connect with no trouble. It's extremely frustrating and I have no idea how to handle the problem. Please help?

Hey Saanasaana, Have you tried going into Settings>General>Reset and tapping Reset All Settings. If still no joy... Reset Network Settings and rebooting the router. If that doesn't do it, try Settings then tap the offending Wi-Fi Network, then tap Forget this Network and re-load it, as if it was a new network.
Your next options are to Restore. Connect to your iPod with your computer with the cable, and make new backups / copies of all your stuff to your computer first, then Restore from Backup. If that does not solve, Restore to New, a full restore. Note restore to new will wipe you iPod put it back to factory specs, that's why your need to make backups of everything on your iPod before you do it so you can reload your stuff back to your iPod. If the full restore does not solve you may have a hardware issue, contact your Apple store or Apple Genius Bar and set up an appointment to have your iPod evaluated. Good luck. Cheers.
