Help with search within pl/sql code
Hi All,
Can you please help me to find all the objects with a database link.
I have some procedures,function and packages which uses database link. I need to fetch all the objects that uses a database link. Is there any way to get the list of object names using any database link?
Thanks in advance
Apppreciate your help!
Thanks
Bob
hi there,
the problem with dba_source is that the code might be wrapped.
another possibility is to query dba_dependencies, column referenced_link
Also you can have pl/sql routines that create dynamically code and might use dblinks in their dynamic code.
So you might not be able to be 100 percent complete.

Please help with search function
Heya, im currently working on code that will allow me to add, view, search and remove prisoners and wardens from a prison system. So far i have managed to allow the user to add and view. Im a bit stuck on the search part of the code, its a bit temperamental :S, sometimes it will find and display the data, but other times it will not and comes up with the error
Exception in thread "main" java.lang.NullPointerException
at Prison.getNum(Prison.java:128)
at TestPrison.main(TestPrison.java:101)
Below i have put my Prison and TestPrison Class files and highlighted the lines the compiler said had the error, any help would be really appreciated because i really cant work out wats going on.

Once again any help would really be appreciated : )The nextPrisoner is null, and you can't call getNum() on a null reference.
Try replacing that line with:if (nextPrisoner != null && nextPrisoner.getNum() == num) Oh, next time you're posting code, please use code tags:

Need help with navigation within a spark list...
hey guys, so in my application when you click on a list item, it opens up an image, and along with the image a few buttons are created dynamically...
the image and the url/labels for the dynamic buttons is provided through an xml/xmlListCollection.
what i need help with is the url or more specifically when you click on one of these dynamic buttons it needs to navigate me to another part of an list or display a certain set of images that is not in my spark list...

i have attached a copy of the xml that i have right now to this post for reference...
any help will be greatly appretiated!!! i've been stuck on this problem for the last week and my project is due soon
again thank you in advance...hey david... just nevermind my previous post... I was able to subclass a link button, so i now have two variables that get assigned to a link button,
one is "tabId" <-- contains the information on which tab to swtich to, and the second is, "changeTo"... this contans the label name which it needs to switch to
I'm just stuck on how to change my selected item in my tabNavigator/list
the code i have right now is
private function customButtonPressed(event:Event):void{
if(event.currentTarget.tabId == "troubleShooting"){
for each(var item:Object in troubleShootProvider){
if(item.@label == event.currentTarget.changeTo){
private function userOptionsChange(event:IndexChangeEvent):void{
dynamicButtons.removeAllElements();
navControl.source = userOptionProvider[event.newIndex].children();
currImage = 0;

as you know, my xml gets divided into two saperate xmllistcollections one is the userOptionProvider, and the troubleshootingProvider
as is in the following xml

tabWidth="137.5" creationPolicy="all" borderVisible="false">

<s:dataProvider>
<s:XMLListCollection id="userOptionProvider" />
</s:dataProvider>

Im having some trouble updating my list... basically change to the troubleshooting tab, and then select the one that i need...
hopefully that makes sence... -

Can anybody help with some subtleties to this code?
Hello,
I was wondering if anyone could take a look at the code in general for me, which is to go in an 'effects' pedal. The first while loop is for a footswitch that either reads high or low. It controls the mode of the pedal. the first mode is the default, where no signal manipulation occurs, and what comes in the audio input just comes out; the second mode stores data (fundamental frequency, average FFT amplitude from 3 kHz to 5 kHz) from the E string of a guitar, which is plucked after that mode is actuated; the third mode does the same for the A string; and the final mode takes in a note on the E or string, recognizes it as either on the E or A string, and adjusts the frequency content to be in tune based the data stored in modes 2 and 3. then the new magnitude vector is put through an inverse FFT and output through the DAC and sounded.
What I'm curious to know is, are there any blatant errors I've made? Will the signal coming out of the inverse FFT be sounded through the DAC? does it need to be changed from a double to an I32? I am trying to debug, but right now I'm having problems getting the correct output voltages on the Blackfin (the SPORT 0 pinout doesn't seem to match what is on the board....).
also, I was wondering if I will lose any phase information on the signal that I get out compared to the signal I put in. Will it be detectable by ear? Or would it all sound the same? along with the phase change for some signals, using an inverse FFT resulted in a loss of amplitude (from about 1 to on the order of 10^-5. that's a lot!). but when the test program was played on my computer, the phase change was not noticeable from the output signal, and neither was the magnitude change! the output played at the same volume as in the input, despite the waveform chart on the front panel showing an amplitude five orders of magnitude less! can you help explain that to me? what can I do, will it matter coming out of the Blackfin and into an amplifier?
i appreciate any input anyone can give me on all this!! thank you!!

102 project.vi 287 KBHi noahgrant,
I've had a look at your vi and can make some suggestions that you can try.
From what I can see, your while loop with the wait timer of 100 ms and continue if true condition on it (we shall cool this loop 1) will always keep running.
The other while loop (loop 2) is nested within a couple of case structures and will only run once (false to a continue if true condition). The default case has a different condition and will always run, instead.
From what I can make of this, loop 2 and all its case structures will only run once (except for case 0, default). WHEN it runs will depend on how it was compiled on the Blackfin - case structure/loop2 may go first or loop 1 will go first.
If you want loop 2 to go first (and only go once) then you need to link the output of the case structure to the input of loop 1 - this can be done by simply wiring up a boolean to it (data flow rules).
If you want loop 2 to always be checking the status of the mode then you need to place the whole case structure within a while loop, to run continuously.
That is a very quick interpretation of what you are trying to do. There are a lot of question marks (missing vi's) and some heavy use of local variables. I would consider using sub-vi's, in particular functional global variables (FGV's).
I hope that helps. -
Need help with division within a query
Hello all~
I am trying to divide these two columns to get a % of case numbers involving an accident. Im pretty sure you need to use decode to avoid the divide by 0 error but not sure how to implement this within my query. When i run this query below, it gives me the result of "1", which is not correct. Can someone help me please?
Oracle Version 10g
ACCIDENT is a datatype VARCHAR
CASE_NUMBER is a datatype VARCHAR
select to_char(count(ACCIDENT),'999,999,999') as "ACCIDENT",
to_char(COUNT(CASE_NUMBER),'999,999,999')as "CASE NUMBER",
round(ratio_to_report(count(accident))
OVER()*100,2)as "%"
from "PURSUIT"
WHERE ACCIDENT = 'Y'
AND
(:P1_BEG_DATE IS NULL AND :P1_END_DATE IS NULL
OR
pursuit_date BETWEEN to_date(:p1_beg_date,'MM/DD/YYYY') and to_date
(:p1_end_date,'MM/DD/YYYY'))
AND(:P1_TROOP=pursuit.officer_troop OR :p1_troop IS NULL)
AND(:P1_RADIO=pursuit.officer_radio OR :p1_radio IS NULL)
group by case_numberThanks
DeannaAre you sure that the ANDs and ORs in your WHERE clause will take precedence properly?
Also, if you always select only cases where there has been an accident, what percentage would you like to display? Surely in this case the percentage of cases involving in accident in cases where there was an accident.. is 100%?
as a simpler example
SELECT
accident,
ROUND(RATIO_TO_REPORT(count(*)) OVER() * 100)
FROM
pursuit
GROUP BY
accidentHere's a trick to neaten up those IS NULLs:
SELECT
accident,
ROUND(RATIO_TO_REPORT(count(*)) OVER() * 100)
FROM
pursuit
WHERE
pursuit_date >= COALESCE(:p1_beg_date, pursuit_date) AND
pursuit_date <= COALESCE(:p1_end_date, pursuit_date) AND
officer_troop LIKE :p1_troop AND
offcier_radio LIKE :p1_radio
GROUP BY
accidentTo wildcard a date, simply pass NULL in; the coalesce will replace the null with the pursuit_date from the record (thus the >= and <= becomes true)
To wildcard the troop or the radio, simply pass a '%' symbol as the value of the parameter. If the front end code is already set up to pass nulls, use the COALESCE trick above -
Need help with select within select - daterange
I use Crystal Reports v12.3.0.601 - I am a beginner.
Problem:
TABLE: ACCOUNTBILLFEE
Columns are
FOLDERRSN
STAMPDATE
BILLNUMBER
PAYMENTAMOUNT
There are over 500,000 rows/ records...
And I need to report the FOLDERRSN which has at least one {ACCOUNTBILLFEE.STAMPDATE} in DateTime
(2014, 05, 01, 00, 00, 01) to DateTime (2014, 05, 31, 23, 59, 59)
Out-put required is:
FOLDERSN | STAMPDATE | BILLNUMBER | PAYMENTAMOUNT
Group by FOLDERRSN
1010234 May01,2014 1111 25000
May25, 2014 1112 5000

1033999 May15, 2014 6752 15000
Dec5 , 2011 1132 25000
Please help -
The critical part for me, is to display payments not within the date range in 'select expert' statement.
Currenlty my report reflects only payments for FOLDERRSN, where {ACCOUNTBILLFEE.STAMPDATE} in DateTime
(2014, 05, 01, 00, 00, 01) to DateTime (2014, 05, 31, 23, 59, 59) and not other payments outside the date range specified.
Thank you for your time.Hi Abilash,
This worked !!!
My brother helped me with it here....ofcourse you have intiated the intial idea.
It worked when i used the following SQL at 'Add Command'
Select * from DATABASE_NAME.ACCOUNTBILLFEE A
Where A.FOLDERSN = any ( select B.FOLDERSN from DATABASE_NAME.ACCOUNTBILLFEE B
where B.STAMPDATE >= TO_DATE('20140501', 'YYYYMMDD')
AND B.STAMPDATE <= TO_DATE('20140531', 'YYYYMMDD'))
Excellent support - Thank you so much for your immediate attention and response.

Verity search results showing SQL code
This site is still in development and that's why the domain
hasn't transferred yet:
http://financial-strategist.dataride-previews.com/index.cfm.
If you perform a search for the word
business, for example, some of the search results display
the SQL query code. How can I eliminate this from being included in
the search results?
My results page is as follows:
<cfsearch
name = "fs_search"
collection = "fsdocs, affdocs, bodocs, profdocs, wibdocs"
criteria = "#Form.Criteria#"
maxrows = "35">
<CFOUTPUT QUERY="fs_search">
<a
href="#url#"><strong>#Title#</strong></a>
<br>
#Summary# <br />
<br />
</CFOUTPUT>There are two ways Verity can index your CF pages (that I know of). One is to do it through the CF Admin Verity Collection and the other is the command line vspider.exe. I believe only the vspider will actually process your CF pages (processing your SQL as well) and the Verity Collection method in the CF Admin will only "read" your CF pages, this "reading" will just display what's in the pages (minus CF includes, etc.).
I could be wrong in this of course because I've learned by trial and error. My experience has been the CF community sites (this one, HOF and Dev Shed) are very slim on Verity help. So I'd say RTFM as much as you can. HTH -
I need help with network install of SQL Developer 3.2
All,
Does anyone have any references on how to perform a network install for SQL Developer? Here is what I'm trying to achieve:
1. Network installation on drive S:\ (Windows, obviously)
2. User links to network installation
3. Connections are unique for each user
I found the 2006 posting of network install for Raptor, but I could not find anything that correlates with the latest release. All I have done so far is downloaded and unzipped. Any help/instructions/guides/tutorials are welcome.You have installed!. The code for SQLDeveloper does not have an installer.
If the software is on S, say a shared drive, each user will start sqldeveloper and a directory called sqldeveloper will be created in their local %APPLICATION_DATA% folder. This will keep all connections etc unique for all users.
You will have to create a link from the S drive to the sqldeveloper.exe if you want a shortcut to start it. We dont provide it.
Thanks

I have a pretty large iTunes library, mostly "classical" music, and I've tried to improve on the Grace Notes database when ripping my CDs into iTunes.
Unfortunately, iTunes does not provide a great foundation for cataloging music with an opus number or a key so I've tried to standardize most things in the name field.
For example, the first movement of a Bach concerto might be listed as "Concerto for violin and oboe in c, BWV 1060: 1. Allegro" using a fairly standard lower case c implying that it is in the key of c minor.
So, to my question: How do I find all the pieces in the key of, say, c minor? When I do a search (in the search field with the magnifying glass on the top right) with the parameters +in c+ I get several thousand pieces listed, many of which do not have the string +in c+. (My total database is about 17,000 songs.) If I try to put quotes around it so that it reads "in c" I get nothing returned.
Is there a way to search for a string of characters including a space that is case sensitive?
Thanks for any assistance.

Help with Searching a Datagrid
I am using the below code to search through a datagrid which is working fine. However, I want to search through more than one column and I can't seem to figure out the syntax. Can anyone help?
It is the city field (highlighted in red below) that tells it to only look at the one column...anyone know how to make it look at several columns?
Thanks.
Dave
private
function onResult(evt:ResultEvent):void
var sort:Sort = new Sort(); sort.fields = [new SortField("city",true) ];

this.homesForSale.refresh();
this.cursor = this.homesForSale.createCursor();}
private function searchCity():void {
if(search_ti.text != "") {
if(this.cursor.findFirst({city:search_ti.text})){
var idx:int = this.homesForSale.getItemIndex(this.cursor.current);
this.grid.scrollToIndex(idx);
this.grid.selectedItem = this.cursor.current;Hi Alex,
Thanks for the response. I should have been more clear in my question. I can add more fields to my Array but if I add them in the function as well, it looks for the combination of the colums...like an "AND" statement...what I want is an "OR" clause...if it is in this column or that column...so I can search through every column in the datagrid.
Another question I have is how to use a variable for the column name. I could loop through it and dynamically put a column name in if it would accept a variable but I can figure out why it won't. In other words, replace the red city with a variable...it keeps giving a Flash player error says it needs a field name.
Thanks for the comments.

Help with searching and replacing
This kind of carries on from the previous topic i posted, but that one came to a bit of a dead end. Here is the code that i have so far:
import java.io.*;
import java.util.*;
class SearchReplaceApp
public static InputStreamReader input =
new InputStreamReader(System.in);
public static BufferedReader keyboardInput =
new BufferedReader(input);
public static void main(String[] args) throws IOException
FileReader file = new FileReader(args[0]);
BufferedReader MyFile = new BufferedReader(file);
StringTokenizer TokenizeMe;
int NumberOfTokens = 0;
int NumberOfWords = 0;
TokenizeMe = new StringTokenizer(MyFile.readLine());
NumberOfTokens = TokenizeMe.countTokens();
while (NumberOfTokens != 0)
for (int WordsInLine=1; WordsInLine<=NumberOfTokens;
WordsInLine++)
System.out.print(TokenizeMe.nextToken()+" ");
System.out.println();
NumberOfWords += NumberOfTokens;
String line = MyFile.readLine();
if (line==null) break;
TokenizeMe = new StringTokenizer(line);
NumberOfTokens = TokenizeMe.countTokens();
String findWord;
String replaceWord;
System.out.println ("Search for?:");
findWord = keyboardInput.readLine();
System.out.println("Replace With?:");
replaceWord = keyboardInput.readLine();
if (line.equals(findWord)) {
line = replaceWord;
System.out.println("\nThis file contains " + NumberOfWords + " words");
MyFile.close();
}The problem is that it asks to search for a word after it has read each line of the file to the screen, instead of just asking when it has read in the whole file, which is what i want it to do. can anyone help me with this?
I think the problem lies in the part :
String findWord;
String replaceWord;
System.out.println ("Search for?:");
findWord = keyboardInput.readLine();
System.out.println("Replace With?:");
replaceWord = keyboardInput.readLine();
if (line.equals(findWord)) {
line = replaceWord;
I would also like the program to display the dedited text after the replace has been completed e.g.
java SearchReplaceApp test.txt
This is a test
This is a test
This is a Test
This is a Test
This file contains 16 words
Search for?: test
Replace with?: Test
This is a Test
This is a Test
This is a Test
This is a Test
Search for?:
etc............................
Any help at all would be appreaciated as im getting a bit frustated with this program and also my own lack of knowledge.
Thanks
