Oracle function to caclulate occurance of a character in a string

Hi All,
I have a string lets say :
'rahul|rahul|rahul|'
I want to calculate the occurance of the charachter '|' which is 3.
PS : I dont want to use connect by or reg_exp and I am using oracle 9i

looking for an oracle built-in function.Sorry, there are only a couple of hundred built-in functions. To do any of the millions of things people want, they sometimes have to combine two or more of those functions, as Paul did.
Acutally, there is a single built-in function that does this, REGEXP_COUNT, but it was only introduced in Oracle 11.1, so it doesn't help you. The fact that they made a new function in Oracle 11 hints that the way to get the same results in earlier versions was too complicated, so don't be surprised if the best way to do this in Oracle 9 isn't as easy you'd like.
What exactly don't you like about Paul's solution?
Paul's solution is what I would use. If you have a reason why you can't use it, say what that reason is, and someone will help you work around it. I can think of other ways to get the same results, including returning 0 when the string doesn't contain any of the designated character, but posting them will only waste your time (not to mention mine) if they have the same problem that Paul's solution has, whatever that is.

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

Function in oracle to find number of occurances of a character in a string

hi,
is there any function in oracle to find the number of ocurrances of a character in a string ?
or is there any simple way of doing the same, rather than writting many lines of code as my program is already very complex.
Maria

Hi Maria,
I don't know of such a function in Oracle, but maybe you could use this:
length(search_string) - length(replace(search_string, character_to_be_found))
For example: select length('Hello') - length ( replace('Hello', 'l')) from dual;
Hope this is what you're looking for

Replacing a character in a string to another character

hi,
i need to write a function or procedure to replace the character of a string value suppose:
l_error:= 'abcdefghijklmnop' is a string
i need write a function or procedure to replace the character "c" to "z"
that data in l_error is not in any table.
thanks,
AJ

I want to Replace all the Existence of the word - "Test" in a string with "Test1" whereever a space exits before the word Test and someother alphabet after "Test" i.e. Test will be replaced with Test1 if a word starts with Test and contains more alphabets also. For example - TestName should be replaced with Test1Name while MyTest should not be updated to MyTest1.
I have tried to use below query which uses oracle regular expressions -
SELECT REGEXP_REPLACE('MYCOMPANY TEST TESTGEET INDIA PVT LTD TEST','\s(TEST)\w',' TEST1') FROM DUAL
Output -
"MYCOMPANY TEST *TEST1EET* INDIA PVT LTD TEST"
Here, it has also replaced the G also from TESTGEET and resulted in TEST1EET while i want TEST1GEET.
Can someone please suggest how can i do this..... may b m doing some silly mistake but sorry m a newbie to regular expression...
Thanks in advance..

How to get a function to return a value occuring after a character

I need to write a function to return the next value occurring after the ":" character in a column. If multiple values of ":" occurs then the function should return the sum of the next value occurring after each ":" in the column.
For example a rating value of 4:1 would return the value of 1. However, the rating of "5:1:1" should return a value of 1+1 = 2, and 6:2:1 will return of 2+1 = 3.
I have the below function skeletion and trying to figure out how the select statement will compute based on the position of : in the column and add the values and return the value back to function.
Function fn_check_internalrating(p_internalrating IN VARCHAR2)
      RETURN number
IS
    cnumber number;
    cursor c1 is
   select ................................
BEGIN
open c1;
fetch c1 into cnumber;
close c1;
RETURN cnumber;
EXCEPTION
WHEN OTHERS
THEN RETURN NULL;
END;

Hi,
You don't need a cursor: there's no table involved in this function, and no point in using any table.
Here's one way:
CREATE OR REPLACE FUNCTION fn_check_internalrating
(   p_internalrating   IN   VARCHAR2
,   p_delimiter            IN   VARCHAR2     DEFAULT     ':'
RETURN NUMBER
DETERMINISTIC          -- Same input always produces same output
IS
    cnumber     NUMBER     := 0;               -- value to be returned
    pos          PLS_INTEGER := INSTR ( p_internalrating
                                    , p_delimiter
                         );          -- position where delimiter was found
BEGIN
    WHILE pos != 0
    LOOP
        cnumber := cnumber + TO_NUMBER ( SUBSTR ( p_internalrating
                                              , pos + 1
                                     , 1
     pos := INSTR ( p_internalrating
                      , p_delimiter
               , pos + 1
    END LOOP;
    RETURN cnumber;
END fn_check_internalrating;
SHOW ERRORSThis assumes the function is a stand-alone function. If it's part of a package, you don't say CREATE OR REPLACE at the beginning.
Try to make functions generic, so that if a similar (but not identical) situation comes up in 6 months from now, you can use the same function. I'm guessing that somethimes you may want to do the same thing with some character other than ':' before each number, so I added the 2nd (optional) argument p_delimiter. You can call the fucntion with either 1 or 2 arguments.
If an error occurs in a PL/SQL fucntion, an error message (showing the exact location of the error) is displayed, and execution halts. If you use an EXCEPTION sectinn, you lose all that functionality, or have to code it yourself. Only use an EXCEPTION handler when you really have to.
For this function, you may or may not want to. For example, if the character right after a delimiter is not a digit, the call to TO_NUMBER in function will raise "ORA-01722: invalid number". You may want to catch that error in an exception handler, and return 0 or NULL. On the other hand, you may want to test that the character after the delimiter is a digit before calling TO_NUMBER, and not have an EXCEPTION section.
What else could go wrong? Try to think of potential problems and fix them when you first write the function. If you discover an error next year, you'll have to spend a fair amount of time finding the function, and getting acquainted with it again.
What should the function return if p_internalrating is NULL, or doesn't contain any delimiters?
What if there's a number longer than 1 digit after a delimiter, e.g. '6:78:9'?

Problem calling Oracle function from Access 2007 / ADO

Hopefully, I'm posting this in the correct forum. I'm also posting on an Access forum as I'm not entirely sure where the issue lies.
I'm calling an Oracle function from Access 2007 using an ADO Command object.
The function takes three input parameters and has a return value and an output parameter. The output parameter is a BLOB, and the return value is varchar2 (either "T" or "N") based on the outcome of the function.
If I pass correct values to the function, I get the following error message (errs out on the command.execute line):
Run-time error '-2147467259 (80004005)':
[Oracle][ODBC][Ora]ORA-06502: PL/SQL: numeric or value error
ORA-06512: at line 1
Here's the function:
FUNCTION GET_ITEMREV_ATTACH(P_ORGANIZATION_ID IN NUMBER,
P_INVENTORY_ITEM_ID IN NUMBER,
P_REVISION IN VARCHAR2,
X_DRAWING OUT BLOB) RETURN VARCHAR2 IS
RESULT VARCHAR2(1);
BEGIN
RESULT := 'T';
BEGIN
SELECT L.FILE_DATA
INTO X_DRAWING
FROM FND_ATTACHED_DOCUMENTS AD,
MTL_ITEM_REVISIONS_B IR,
FND_DOCUMENTS_TL D,
FND_LOBS L
WHERE AD.ENTITY_NAME = 'MTL_ITEM_REVISIONS' AND
AD.PK1_VALUE = IR.ORGANIZATION_ID AND
AD.PK2_VALUE = IR.INVENTORY_ITEM_ID AND
AD.PK3_VALUE = IR.REVISION_ID AND
AD.CATEGORY_ID = 1001216 AND
D.DOCUMENT_ID = AD.DOCUMENT_ID AND
D.LANGUAGE = 'US' AND
L.FILE_ID = D.MEDIA_ID AND
IR.ORGANIZATION_ID = P_ORGANIZATION_ID AND
IR.INVENTORY_ITEM_ID = P_INVENTORY_ITEM_ID AND
IR.REVISION = P_REVISION;
EXCEPTION
WHEN OTHERS THEN
RESULT := 'N';
END;
RETURN(RESULT);
END GET_ITEMREV_ATTACH;
Here's the VB code I'm using to call the function:
Private Sub Command8_Click()
Dim CMD As New ADODB.Command
Dim conn As ADODB.Connection
Dim Param1 As ADODB.Parameter
Dim Param2 As ADODB.Parameter
Dim Param3 As ADODB.Parameter
Dim ParamBlob As ADODB.Parameter
Dim ParamReturn As ADODB.Parameter
Set conn = New ADODB.Connection
With conn
.ConnectionString = "Driver={Oracle in OraHome92};Dbq=OAPLY;UID=***;PWD=*******"
.CursorLocation = adUseClient
.Open
End With
Set CMD = New ADODB.Command
Set CMD.ActiveConnection = conn
CMD.CommandText = "immi_attach_pub.get_itemrev_attach"
CMD.CommandType = adCmdStoredProc
Set ParamReturn = CMD.CreateParameter("RESULT", adVarChar, adParamReturnValue, 1)
CMD.Parameters.Append ParamReturn
Set Param1 = CMD.CreateParameter("P_ORGANIZATION_ID", adInteger, adParamInput, 1, 6)
CMD.Parameters.Append Param1
Set Param2 = CMD.CreateParameter("P_INVENTORY_ITEM_ID", adInteger, adParamInput, 4, 5207)
CMD.Parameters.Append Param2
Set Param3 = CMD.CreateParameter("P_REVISION", adVarChar, adParamInput, 2, "04")
CMD.Parameters.Append Param3
Set ParamBlob = CMD.CreateParameter("X_DRAWING", adLongVarBinary, adParamOutput, 200000)
CMD.Parameters.Append ParamBlob
CMD.Execute , , adExecuteNoRecords *** this is where the error occurs
conn.Close
MsgBox CMD.Parameters("RESULT")
End Sub
I've tried using different data types for the varchar2 parameters (adVarChar, adBSTR, adChar) with no difference.
If I pass a bogus value for Param3...."'04'"...the function returns "N" indicating that it actually executed something. But, when I pass the correct value "04", it returns the above mentioned error.
I can execute the function in PL/SQL just fine, so I'm thinking there's something wrong with the parameters, datatype, or other definitions on the Access side.
Does anyone have any thoughts? I'm at a dead end with this. Sorry for the long post. Thank you.

I tried your code with 11107 ODBC/client/database (but with a NULL output blob for convenience sake) and got no errors.
If you're using 92 ODBC/client, you may want to try upgrading to something more current, or at least getting the latest patch(9208) to see if that helps. Since it works for me I'm guessing it may be a resolved bug in that version.
Hope it helps,
Greg

Calling oracle function in OMB script

Hi
Can anyone please tell me how can i get the returned value of an oracle function in OMB script. or how can i get the value into OMB variable and use it.
Basically i want to set the properties of OWB mapping via OMB script.
Following OMB code sets the max error limit of a mapping.
OMBALTER MAPPING 'MAP_DATA' SET PROPERTIES (MAXIMUM_NUMBER_OF_ERRORS) VALUES ('100')
i dont want to hard code the value 100 rather i want this value to be returned from a function.
If it is not possible then plz tell me how can i set MAXIMUM_NUMBER_OF_ERRORS property of OWB mapping via sql or pl/sql.
Any type of clue will be highly appreciated.
Best Regards

Here is my bare-bones OMB SQL Library to allow you to do pure SQL calls from within OMB+. All I have ever used it for is to run queries, so I don't have a library procedure for calling a function, however if your function is SQL-callable (e.g. select my_func() from dual) then it would work. Either that or you'll want to augment this library to build a procedure that will call and return the results from a java preparedStatement. It's something I've been meaning to do, but haven't got around to it yet.
All you should need to do is save this as it's own tcl file and then source it at the top of your own script, or embed it into your script.
EDIT: Here is a page with some sample code on using java.sql.CallableStatement to call a Pl/SQL procedure from Java which should certainly do the trick for you in conjunction with the basic session control in my library.

SELECT LOAN_CODE,LOAN_DATE,DUE_DATE,LOAN_AMT FROM LOAN_MASTER
order by P_SROT;
return C_testssk;
end;Edited by: user10736825 on Dec 22, 2010 11:34 AM

you can go for a dynamic query ;)
create or replace
FUNCTION TEST_SSK
p_srot number
RETURN SYS_REFCURSOR
AS
C_testssk SYS_REFCURSOR;
l_str VARCHAR2(4000);
l_order VARCHAR2(100);
BEGIN
l_str := 'SELECT LOAN_CODE,LOAN_DATE,DUE_DATE,LOAN_AMT FROM LOAN_MASTER ';
IF p_sort = 'LC'
THEN
l_order := ' ORDER BY LOAN_CODE ';
ELSIF p_sort = 'LD'
THEN
l_order := ' ORDER BY LOAN_DATE ';
END IF;
l_str := l_str || l_order ;
OPEN C_TESTSSK FOR l_str;
return C_testssk;
end;
