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

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

tried the above one but no luck.

To get the count of records and able to access the column value in a single

Hi
Is there any way to get the number of records in the query and access the column values
e.g
select count(*)
from
(SELECT department, COUNT(*) as "Number of employees"
FROM employees
WHERE salary > 25000
GROUP BY department ) a
This wil only get the Count, if i want to access each row from the inline view how can i do that.

Your question is not clear.
Are you looking for total record count as well as count by department ?
Something like this?
SQL>
SQL> with temp as
2 (
3 select 1 dept ,10000 sal from dual union
4 select 1 dept ,25100 sal from dual union
5 select 1 dept ,30000 sal from dual union
6 select 1 dept ,40000 sal from dual union
7 select 2 dept ,10000 sal from dual union
8 select 2 dept ,25100 sal from dual union
9 select 2 dept ,30000 sal from dual union
10 select 2 dept ,40000 sal from dual )
11 select count(*) over( partition by 1 ) total_count,dept,
12 count(*) over(partition by dept) dept_cnt from temp
13 where sal>25000;
TOTAL_COUNT       DEPT   DEPT_CNT
          6          1          3

Append string to each column value

JUPITER revolves around the sun
EARTH is a planet
EARTH is almost round
EARTH revolves around the sun
MARS is a planet

.Any idea how I could do this ?

You'll need to cross join a set of three rows to your base table.
There are different ways to do it, for example :
SQL> select name1 ||
2 case n when 1 then ' is a planet'
3 when 2 then ' is almost round'
4 when 3 then ' revolves around the sun'
5 end as final_name
6 from test1
7 cross join (
8 select level n
9 from dual
10 connect by level <= 3
11 )
12 order by 1
13 ;
FINAL_NAME
EARTH is a planet
EARTH is almost round
EARTH revolves around the sun
JUPITER is a planet
JUPITER is almost round
JUPITER revolves around the sun
MARS is a planet
MARS is almost round
MARS revolves around the sun
VENUS is a planet
VENUS is almost round
VENUS revolves around the sun
12 rows selected
SQL> select name1 || text as final_name
2 from (
3 select name1
4 , ' is a planet' as text1
5 , ' is almost round' as text2
6 , ' revolves around the sun' as text3
7 from test1
8 )
9 unpivot (text for text# in (text1, text2, text3))
10 ;
FINAL_NAME
JUPITER is a planet
JUPITER is almost round
JUPITER revolves around the sun
EARTH is a planet
EARTH is almost round
EARTH revolves around the sun
MARS is a planet
MARS is almost round
MARS revolves around the sun
VENUS is a planet
VENUS is almost round
VENUS revolves around the sun

Program to count the no. of times a character occurs in a string.

program to count the no. of times a character occurs in a string.
Say if u have a method :- Countclass(string s,char c) then using this u should be able to count a char ' T' in the string ="TESTING".
So it is appering 2 times.
How to count it.

int countChar(String s, char c) {
 int count = 0;
 for (int i=0; i<s.length(); i++) {
 if (s.charAt(i) == c)
 count++;
 return 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

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.
Regards,
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.
