Oracle 8 pattern matching

Hi all,
I need to extract some data from a text field in an Oracle 8 database. I also need to do this within a stored procedure.
The data in the text field is of variable length, and is unformatted, containing name value pairs and other items. Somewhere in the text will be a substring like "foobar=12345" (without the quotes), I want to return the value 12345. The text "foobar" is constant, but the following number is variable and of variable length.
The best approach I can think of is to find the location of the constant text "foobar=" and create a substring starting after the "=" and terminating on the first subsequent non-numeric character. However, I understand that regular expressions are not supported, or not well supported in Oracle 8.
How would you solve this? Sadly, remodelling the data to store the foobar value in its own field is not an option.
Thanks,
Jack

Does Oracle 8 have the OWA_PATTERN package?

OBIEE 11G : Remove label (is like pattern match) in the prompt

Hi Experts,
I have Gone through this thread Re: OBIEE 11G : Remove label (is like pattern match) in the prompt and applied JS as mentioed but
It works for the first display of the page but its back as soon as you hit the apply button
can be it be removed permanently? Thanks in Advance

Hi Nagen,
You can try the following:
Create a variable prompt with the column vales that you want to match
Create a filter in the analysis criteria tab on the column, set to pick up the variable, and define the IS LIKE here.
It is effectively doing the same task as the standard prompt approach does, but in a round-a-bout way which doesn't include adding any of Oracle's text in.

The featest pattern match

Now I met a difficult question.Firstly,we have a criterion table as below:Combination Name     Service     UnitLength     UnitHeight     LoadStatus     Bill No ......(until unbounded fields). Some data like this
Combination Name |     Service |     UnitLength | UnitHeight | LoadStatus |     Bill No ......
COM1 | CSC | 40 | 96 |
COM2 | CSC | 40 | 96 | F |
COM3 | CSC | 40 | 96 | F | SEA-SCS
If there is an object has the attribute UnitLength equal 40 and UnitHeight equal 96 the correct combination COM1 is selected;otherwise, if
it has the attribute UnitLength equal 40 and UnitHeight equal 96 and LoadStatus equal F then the appropriate combination COM2 is selected; then if the object has UnitLength equal 40 and UnitHeight equal 96 and LoadStatus equal F and many other conditions ,the featest pattern match will be the completely match combination.But when there is no completely match combination,we may get a combination closer match the object.For example,an object has the following attributes UnitLength equal 40 and UnitHeight equal 96 and LoadStatus equal F Bill No equal SEA-SCS* ,the best result will be COM3.
How can we find a pl/sql procedure resolve this question?
Thanks very much! Look forward to your answer!

my best would be to do something like the following since i don't have oracle and can't simulate it right now:
select a.*,
       case when unitlength = 40 and unitheight = 96 and loadstatus ='F' and billno = 'SEA-SCS' then 'COM3'
              when unitlength = 40 and unitheight = 96 and loadstatus ='F' and billno != 'SEA-SCS' then 'COM2'
              when unitlength = 40 and unitheight = 96 and loadstatus != 'F' then 'COM1'
              else 'print what ever you want'
       end
from <table_name>
where <any_conditions_you_want_if_any>
;

Need to know the best method for pattern matching

Hi,
I need a best a way to do the pattern matching with better performance
for the following requirement.
i need to search for a set of records as per the following requirements.
1. The input string will be split into tokens with space as delimiter
so if the user enters the text 'severe head ache',the tokens formed will be
severe
head
ache
2. The terms which contain exact match of the tokens formed should be fetched from the database
(i.e)
i. the token should appear in the term as such and no alpha-numeric character should be appended to it but a single space or any single non alpha-numeric characer is allowed
ii. the token may occur anywhere in the string.(like start, end, middle etc.)
iii. the term should contain all the tokens
For ex. the following terms will be fetched for the above input
1. patient has severe head ache
2. severe, head ache are present
3. leg pain "severe" #head pain
4. pain, severe in head, leg
But following terms should not be fetched
1. severe leg pain - (it does not have the token 'head')
2. headache severe and leg pain - (head is a part of the word headache)
3. head67 severe pain - (head is a part of the word head67)
Thanks

Finding pattern match based on Octal characters

I have Octal values of various characters. For example:
€ = Octal value 128
I need to use the Octal values of various extended ascii characters and based on these values I need to do a pattern search.
According to the pattern class document, I can represent octal as:
patternStr = "\\o128";
http://download.oracle.com/javase/1....x/Pattern.html
Pattern p = Pattern.compile(patternStr);
Matcher m = p.matcher("aaaaab€aaaaa");
boolean b = m.matches();
If I do the above, then the match is not found. Can anyone tell me why? What is that is wrong in this code.
Mark

Getting Log File Pattern Matched Line Count metric to work ?

Hi
has anyone been able to get this to work with more complex Perl expressions ?
Basically I can get simple, single expressions to match.
EG *(does not exist)* will match the text *"does not exist"* anywhere in a file.
However, if I want to match either does not exist OR file not found I should be able to do something like
*(does not exist)|(file not found)* OR *(does not exist|file not found)* but this just doesn't work.
I want to be able to do more complex expressions, using *\i* (ignore case), and *^* (start of line) *$* (end of line) expressions too.
I can test the matching functionality using a simple perl program, and I know the expression works in Perl.
Oracle is supposed to be using a perl pattern match but seems to fail unless it is a single simple expression.
Anyone been able to use this functionality at all.
Many thanks.

I have a chance to look into the parse-log1.pl script which is responsible for monitoring the log files and generating the alerts for EMGC. I am just pasting the comments given in this file
# This script is used in EMD to parse log files for critical and
# warning patterns. The script holds the last line number searched
# for each file in a state file for each time the script is run. The
# next run of the script starts from the next line. The state file name
# is read from the environment variable $EM_STATE_FILE, which must
# be set for the script to run.
but in my case this is not happending according to log files it is storing the lst read line of the log file but it is not using that info in its next run. The file will be scanned from the begining again but this is not the case with emagent.log file monitoring its working fine as expected and explained in the script file.
According to my observation this is becasue of the script is rotating my log file for each run i dont know how stop it. I just want to scan my log file I dont want to rotate my log file for each run of the script. Could any one please help me to solve this problem
Thanks

How do I set multiple pattern matching Vi's and make overlapping pattern matches to count as one?

Hello! I'm a student and I'm currently making a project using pattern matching.
My patterns are from chick foot/feet.
I'm created multiple pattern matching VI's to detect all the feet because I find it difficult/impossible to match all the feet with a single pattern/template.
However, when using multiple pattern matching VI's some pattern matches detect the same foot, hence overlapping.
So how can I make the overlaping pattern matches to be counted as one?
Thank you in advance

Thank you for replying Sir Zwired1.
I'm still a newbie in using LabVIEW so pardon me if I can't understand fully
The objective of my project is to detect all the feet through pattern matching and count the pattern matches made.
"Keep a 2D array of counts, initialized to zero and the same size as your array of possible locations, and increment the value every time you get a match. If multiple pattern matching attempts result in a match a given location in your count array might be "3" but all you care about is if the number is greater than zero."
I'm sorry, but how do you do this? BTW, I'm using vision assistant.

Trouble using a pattern match in the GO URL when the value starts with %

Hi guys,
We are trying to use a Go URL as follows:
[http://hostname.com:9704/analytics/saw.dll?Go&Path=/users/administrator/Test/TestReport&Action=Navigate&col1=TestReport.SUBJECT&op1=like&val1="%25D8D8%25"|http://hostname.com:9704/analytics/saw.dll?Go&Path=/users/administrator/Test/TestReport&Action=Navigate&col1=TestReport.SUBJECT&op1=like&val1="%25D8D8%25"]
Basically, we want to send the filter : SUBJECT like '%D8D8%' in the GoURL. However, the report that opens up does not fetch any rows because BI somehow messes up the clause by not recognizing the leading %25 (which is an escaped % character). Instead it resolves the %25D8D8%25 into something like �D8% .
As you can see, the %25 at the end however gets resolved correctly but somehow the one at the beginning gets clubbed with the leading D8 to give �.
Any idea, how to get BI to accept a leading escaped % character when doing a pattern match in the Go URL?

How can I read a template and differentiate if it is a pattern matching template or a geometric matching template?

Hey all,
I would like to know how can I read a template´s information to know if it is a pattern macthing or a geometric matching template?
In my code, users provide templates and the algorithm must match them using pattern matching or geometric matching depending on the template.
At the moment I am doing it by including a P or a G in the name of the file, but I would like to avoid this and read the information from the file.
Any ideas?
Thanks in advance,
Esteban

Hey Esteban,
you can use the VI "IMAQ Is Vision Info Present 2 VI" to reice the information:

Is there a way to turn the pattern matching example in Labview to instead of loading a rectangle around what you want the template to be you can use an image display , I've be trying and can get no where with it

What I want to do is , have two images on image displays and the pass them through the same setup as the pattern matching example to get the number of matches , I have attached what I have done and also given the pattern matching example program as well.
Hope to get answers back soon,
Thanks Alan

Hi there!
The example used can be adapted for comparing two images, however the algorithm and coding for finding the differences is more specific to your actual problem. In terms of the loading and displaying of the images, this can be done in the same way.
Once you have some sort of algorithm, then you can automate the learning and matching by simply wiring them in order. (in the example, these are put in case structures as they are waiting on response from the front panel)
I hope that this helps,

Regular Expressions (Pattern/Matcher) --- Help

Hi,
I have an regex i.e. Pattern.compile("([0-9])D([0-9])'?(?:([0-9]+)\")?([NSEW])").{code}
It has to exactly match the input e.g *45D15'34"N*
I need to retrieve the values based on grouping.
Group1 = 45 (degree value)
Group2 = 15 (minutes value)
Group3 = 34 (seconds value) ----> this is a non-capturing group
Group4 = N (directions)
The regex works fine for most of longitude/latitude value but I get a StackOverFlow for some. There is a known bug on this http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5050507
According to the bug report, they have said that are many different regex that can trigger the stack overflow....even though the length of my input is not as long as the one posted on the bug report.
I was wondering if anyone could suggest a different way of writing the regex above to avoid the stack over flow.
Thank you in advance

Hi,
I missed the '+' in my original regex Pattern.compile("([0-9]+)D([0-9]+)'?(?:([0-9]+)\")?([NSEW])"){code}.
I have also tried {code} Pattern.compile("(\\d+)D(\\d+)'?(?:(\\d+)\")?([NSEW])");And, the other 2 expressions as suggested by you.
The problem happens when Durham Lat=35D52N Lon=78D47W value is selected from a Jtree(the values are parsed from a xml file to the tree - the xml file has a bout 800 longitude/latitude elements for different cities in the US). It does not happen for other values and If I increment the degree or min by, then the expression works. I am not sure how else i could re-write this exp.
Below is the snippet of the xml file:

I have done the following so far, but the issue is not getting resolved.
1) Generated JAR files using ADADMIN (Force)
2) Compiled JSP
3) Ran autoconfig multiple times without any error in both db and application tiers.
4) DB alert log did not have any error.

Who knows how to output some text once labview detects something I want using pattern matching(Vision assistant)?

who knows how to output some text once labview detects something I want using pattern matching(Vision assistant)?
The text is something like"Yes, this is a coin"
Thanks!

I attached a SubVI which I used to place an overlay next to a Pattern, found by a Pattern Match before:
As you can see, you simply pass the image reference and the Array of Matches to the VI along with the String you want to have as an overlay next to the Match.
I also modified your VI a bit, but didn't test it. I created an Array of clusters, each elment containing the template path along with the respective text.
Please note that this is just a hint!

Please anyone give example..

Stop asking these stupid vague questions and do some of your own research.

Pattern Matching and Vision Builder 6.0

Hi,
When I select a ROI from an image to generate a pattern matching, Builder
saves it as a PNG file.
If I open this pattern in other application (Paint Shop Pro 7) to modified
it and save as a PNG file, after I can't open this file as a pattern into
Builder, because it is considered as a not valid PNG file.
I have tested this case in LabView 6.i and this problem doesn't appear.
Any solution? Thanks.

When the template is first saved in Vision Builder, pattern matching information is stored in the header of the PNG file. This information lets LabVIEW and Vision Builder know how the template was learned. Paint Shop Pro does not keep this information in the file whenever it is saved so Vision Builder will not recognize it as a valid pattern matching template.

Pattern matching problme - not getting desired result.

Hi,
According my program , If 'san' is in 'sangeetha', then it should display "hello".
but I am getting only 'hi'
Why ? any idea?
<%@ page import="java.util.regex.Pattern"%>
<%
if(Pattern.matches("san", "sangeetha"))
out.println("hello");
else
out.println("hi");
%>
Result : Hi
