Getting count of occurances of a string in a within a string

Dear all,
I want to find how many times the particular number 11 is present in the string ',11,12,13,14,11,16,17,11,23,11,'.
expected answer 3.
Please help me to write the sql statement.
SQL> select length(regexp_replace(',11,12,13,12,11,', '[^11]')) / length('11') cnt from dual;
CNT
3.5
tried the above one but no luck.
Regards
Rajat

regexp_count ... But I see 4 11's .. Did I miss anything?
SELECT REGEXP_COUNT (',11,12,13,14,11,16,17,11,23,11,', ',11,') FROM DUAL;
Cheers,
Manik.

Getting count of occurances of a string in a column value

Hi,
Is there a way to get the number of occurences of a string in a single column value?
Example:
CREATE TABLE STRING_CNT(X VARCHAR2(100));
INSERT INTO STRING_CNT(X) VALUES('OracleXXOracleXXOracleXXOracle');
Commit;
Now the string 'Oracle' is repeated 4 times in the inserted value. I would like to get this count using SQL.Can some one tell me how to get this?
I was asked this interesting question in an interview today.

hi 
u can get the occurrence of a string in text as
follow 
>
SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) 
/ LENGTH('Oracle') as 
Occurrence FROM STRING_CNT; 
 
Are you sure...? 
 
 
SQL> with STRING_CNT as
2 (select '1.Oracle2.Oracle3.' x
3 from dual)
4 SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) / LENGTH('Oracle') as Occurrence
5 FROM STRING_CNT;
OCCURRENCE
1.66666667

To count number of occurances of a char in a very large string

Hi All,
I like to count the no of occurances of a char in a a very large string.
for example
char ch - 'c'
string str - "practical example is always needed"
c occured 2 times in the above string.
Thanks,
J.Kathir

> string str - "practical example is always needed"
Try to finish this:
 String str = "practical example is always needed";
 char search = 'c';
 int occurrence = 0;
 for(int i = 0; i < str.length(); i++) {
 // Use a method from the String-class to get a
 // char from a specific location in the String.
 // See: http://java.sun.com/j2se/1.5.0/docs/api/java/lang/String.html
 System.out.println("Occerrence of char "+search+" in \""+str+"\" is: "+occurrence);

Count the occurance of a character in a string

What is the function to count the occurance of a character in a string.
like 'test test1 test2 test3' with in this string there are 3 white spaces.
instr will give the first one, replace will change the all... and what's for the occurance (number of white spaces, which is 3 in this case) count

[Question]how to count the occurance of numbers inside the array

im just practicing my java skill but i cant get my program work can you give me guys some idea on how to determine a number that occured more than 1 inside the array e.g i have 10 elements and inside of my offset i have
1,2,5,4,5,6,5,8,9,5
and what im planning to do is count the occurances of the number who occures more than 1 and for that 5 occur 3 times how my program can know that i use for loop but cant figure out how to filter the occurances of numbers inside
my offset
thank's

Encephalopathic you said put - 1 instead i did - 2
public class sample
 public static void main(String args[])
 int num[] = {2,2,2};
 int index1, count = 0, find = 0;
 for(index1 = 0; index1 < num.length - 2; index1++)
 for(int index2 = 0; index2 < num.length; index2++)
 if(num[index2]==num[index1])
 find = num[index2];
 count++;
 System.out.println("i found " + find + " " + count + " same number inside your offset");
}output is:
i found 2 3 same number inside your offset
but another question is what if i want my program to tell the other number that occur 1 time
like this:
i found 1 2 same number inside your offset
i found 2 0 same number inside your offset
i found 1 2 same number inside your offset

Get count with Scope to show only once against rows

Hi I Have a matrix table with month on the rows and Year on the Columns
The expression I am using for the data is
=Count(Fields!data.Value,"Year")
This shows like this
2011_H1
Month 1 256
Month 2 256
Month 3 256
Month 4 256
Month 5 256
Month 6 256
I only want to show the data value once so it looks like this
2011_H1
Month 1 256
Month 2
Month 3
Month 4
Month 5
Month 6
I have tried using in the text box visibilty
=Iif(Previous(ReportItems!data.Value)=ReportItems!data.Value, true, false)
But I get an error message about aggregate functions can only be used on report items
How can achieve this?
Regards

Hi aivoryuk,
Just as you said, the previous aggregate function couldn’t be used in a tablix cell in Reporting Services. After testing the issue in my local environment, we can refer to the following methods to work around the issue.
Method1: Use RowNumber function to control the textbox visibility to only show the last value in the Year column.
Right-click the cell which contains the expression “=Count(Fields!data.Value,"Year")” to open the Text Box Properties dialog box.
Select Visibility tab, use the expression below to control the visibility:
=iif(RowNumber("Year")=reportitems!Year.Value,false,true)
The following screenshot is for your reference:
Method2: Use custom code to get the previous value.
Copy the custom code below and paste it to your report. (Right-click report>Report Properties>Code)
Public Shared previous as string
Public Shared current as string
Public Shared Function GetCurrent(Item as string) as string
previous=current
current=Item
return current
End Function
Public Shared Function GetPrevious()
return previous
End Function
Replace the original expression
=Count(Fields!data.Value,"Year")
with
=Code.GetCurrent(count(fields!data.Value,"Year"))
Use the following expression to control the visibility of the textbox:
=iif(Code.GetCurrent(count(fields!data.Value,"Year"))=Code.GetPrevious(),true,false)
The following screenshot is for your reference:
If you have any other questions, please feel free to ask.

Do you have any suggestions?

I need to WAP to count the number of occurences of an alphabet in a string.

I need to WAP to count the number of occurences of an alphabet in a string.I tried a lot and have surfed a lot regarding this problem.
I m not the most proficient with java.but this is all i could come up with,and would appreciate some help here.I hope you guys would help me find a solution to this.
e.g String : abcabrty
Result should be
a:2
b:2
c:1
r:1
t:1
y:1
public class chkoccurences
 public static void main(String args[ ])
 String user_Data=args[0];
 int counter=0;
 try
 for(int i=0;i<user_Data.length( );i++)
 for(int j=0;j<user_Data.length( );j++)
 if(user_Data.charAt(i) == user_Data.charAt(j))
 counter++;
 System.out.println(user_Data.charAt(i)+" exists "+counter+" time(s) in the word.");
 System.out.println(" ");
 catch(ArrayIndexOutOfBoundsException e)
 System.out.println("Check the array size.");
}This is the output i get out of the program:
a exists 2 time(s) in the word.
b exists 4 time(s) in the word.
c exists 5 time(s) in the word.
a exists 7 time(s) in the word.
b exists 9 time(s) in the word.
r exists 10 time(s) in the word.
t exists 11 time(s) in the word.
y exists 12 time(s) in the word.What i think is i need an array to store the repeated characters because the repeated characters are getting counted again in the loop,if you know what i mean.
Please, i would appreciate some help here.

Criticism is welcomed
public class tests {
 final int min = 10;

Getting multiple counters with get-counter ?

Just trying to get a handful of counters for sql server monitoring. but is there any way i can export-counters all into 1 .blg file or am i not getting this ? do they have to be in the same set i guess is the question.
Counters like :
Get-Counter "\\$computer\processor(_total)\% processor time"
Physical Disk: Average Disk/sec Reads
Physical Disk: Average Disk/sec Write
SQL Server: Memory Manager >> Free List Stalls/sec
SQL Server: Memory Manager >> Memory Grants Pending
thanks,
Chris

Mike, once again, thanks.
I guess i need to find out how to read the cmdlet powershell syntax. from the documentation that you've sent, and which i've read before, i can't find where you can comma separate counters. clearly, i need to decipher the syntax which is not
too clear.
That is why it is important to take a course or read a book or use the training materials on this site. The raining answers these obvious questions. It is like buying a new car - first you read the owners manual.
In the first couple of lessons the syntax of the CmdLets are explained.
You can also use help to discover how they work.
The CmdLets shows you how to call a CmdLet with an array of strings. A comma separated list of any kind is an array.
(1,2,3,43,5).GetType()
¯\_(ツ)_/¯

Ordering of objects by more than one field and get counts

i have an object visit (personid, city, street, place, date)
A person could have visited a same place in the same strret in the same city several times on different dates.
I have a visits 'Set' for a person and I have to get a count of visits he has done to a place..
its basically select count(visits) group by city, street , place.
I know to use interface comparator for a single field.. how to compare multiple fields and get counts??
if you know abt where i can find information please let me know.
Thanks.

For multiple fields, your comparator compares the most significant field first. If they're unequal, it returns +/- accordingly. If they're equal, then it moves on to the next field. And so on, until, finally, if all the relevant fields are equal, then the objects are equal.
Just like what you do when comparing, say, last names. If the first letters are unequal, you're done, else move onto the next letter, and so on..
For the count, you wouldn't use a comparator, as that's for sorting. Exactly how you do it depends on the details of what you're storing and how, which you haven't provided.

Why do I get "Error 1 occured at Config Data Registry.vi(get data) invalid object 0" while starting my application?

Why do I get "Error 1 occured at Config Data Registry.vi(get data) invalid object 0" when starting my application created in LabVIEW 7.1? I am starting the application in a PXI rack running Windows XP. I have an executable written in LabVIEW 7.0 that runs without this error. After clicking the Continue button in the error, the application seems to continue happily.
Is there something I need to include when I make the executable?
I would like to understand and eliminate this start up error.
Thanks in advance.

Hi Bob,
I looked through the program and I figured out where the error is coming from, and potentially what is causing it. In a lot of the cases of the program you are searching a 1-D array for the name of the case, and if you don't find it then it skips the function and gives "Error 1 occurred at Config Data Registry.vi(CASENAME) invalid object 0". I attached a screenshot that shows what I mean. The Search 1-D Array.vi is returning a -1 which means it didn't find the case. The reason I believe this is happening is because the shift register for that array is not initialized. While the other cases "reset" and "register" interact with the array shift registers and most likely create the array you need, if the program defaults to the "get data" case then it will try to run that before registering and won't have an array to search. This would also explain why it only has this problem at first and seems to run just fine after that. To fix this you should either make an initial array and wire it into the shift register or make the "reset" case the default as opposed to the "get data" case.

Peter W.

Move to new computer, get "An error occurred while reading files or writing files to disc. The disc

I tried to move my PE6 install and catalog to a new computer. It was on a Dell Windows XP machine, and I moved it to a Toshiba Windows 7 (64 bit) machine. I have always kept my photo files on an external hard drive. My photo library is 50GB, 10,000 files. Here is what I did.
Copied the original PE6 install file to the Toshiba. Installed but didn’t activate it.
Copied the entire My Catalog folder to the proper Windows 7 location.
Plugged the external drive into the Toshiba. Made sure the same drive letter as before (E).
Fired up PE6 on Toshiba. Looked good in Organizer. Everything seemed to be there, but I didn't try to make changes at that point.
Deactivated PE6 on the Dell. Activated on the Toshiba.
Then I realized that it is not right. I can edit Keywords and Rating stars on the pics, but not dates, captions or notes. I get “An error occurred while reading files or writing files to disc. The disc may be full or there may be problems with the source media.”
Only a fraction of the external drive is in use.
I can access the files on the external drive with another app (Windows Photo Viewer).
I tried Reconnect All Missing Files. Somewhat ambiguously, it says “There are no files to reconnect.”
In the properties in the Organizer for each picture are the proper file names and paths. Folder view works fine in Organizer.
I can put new files in the same external drive directories, import them into PE6, then edit them normally.
What is the easiest way to get Organizer properly connected to my files? I suppose I could reimport all the pics on the new machine, but I assume I'd lose some of my metadata. So that is out of the question.
Thanks,
Bill

Are you sure that file paths are correct? I say this because under XP they would have originally pointed to Documents & Settings/My Pictures whereas on W7 it will be User/Pictures, albeit you are using an external hd.
Take a look at this knowledge base note on the correct procedure for back-up and restore.
I think writing metadata to files for such a large catalog will be a thankless task.
