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

Find number of occurances of a particular character

Hi,
is there any keyword to determine number of times a particular character is present in the string,
E.g. VAR1 = 'ghghj#ghjgjgh#ghjghjg#ghjg#'.
I want to find number of occurances of # in VAR1.
Regards,
Raghavendra

Hi,
       use folowing logic.
       data:begin 0f itab,
                var1 type c,
                 var2 type c,
                 var3 type c,
                  var4 type c,
              end of itab.
split var1 at '#' into itab-var1 itab-var2 itab-var3 itab-var4.
    if not itab-var1 is initial.
        count = count + 1.
    endif.
       if not itab-var2is initial.
        count = count + 1.
    endif.
    if not itab-var3is initial.
        count = count + 1.
    endif.
    if not itab-var4is initial.
        count = count + 1.
    endif.
write count.

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

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.

use the EM_GET_NUMBER_OF_ENTRIES. You just have to write your table name into the input table IT_TABLES in the TABNAME field

How to find number of lines in an internal table

Dear all,
how to find number of records present in an internal table.

DESCRIBE TABLE
Syntax
DESCRIBE TABLE itab [KIND knd] [LINES lin] [OCCURS n].
Extras:
1. ... KIND knd
2. ... LINES lin
3. ... OCCURS n
Effect
This statement determines some properties of the internal table itab and assigns them to the specified variables. The various additions enable you to determine the table type, the number of currently filled rows and the initial memory requirement.
In addition, the system fields sy-tfill and sy-tleng are filled with the current number of table rows and the length of a table row in bytes.
Notes
For detailed information about an internal table, you should use the methods of RTTS of the DESCRIBE TABLE statement.
Without the specification of an addition, the statement DESCRIBE TABLE only sets the system fields sy-tfill and sy-tleng.
Addition 1
... KIND knd
Effect
The table type of the internal table itab is determined and a corresponding one-digit identification is assigned to the data object knd. A character-type data type is expected for the data object. The identifications are "T" for standard tables, "S" for sorted tables and "H" for hashed tables. These values are also defined as constants sydes_kind-standard, sydes_kind-sorted, and sydes_kind-hashed in the type group SYDES.
Addition 2
... LINES lin
Effect
The current number of table rows of the internal table itab is determined and is assigned to the data object lin.The data type i is expected for the data object.
Note
As of release 6.10, the current number of rows of an internal table can also be determined using the in-built function lines.
Addition 3
... OCCURS n
Effect
The initial memory requirement defined during the creation of the internal table with the addition INITIAL SIZE or the obsolete addition OCCURS is determined and assigned to the data object n. The data type i is expected for the data object.
Example
Descending sorting of a generically typed internal table in a subprogram. Since sorted tables cannot be sorted in a descending order, the table type is checked to avoid an exception that cannot be handled.
TYPE-POOLS sydes.
FORM sort_descending CHANGING itab TYPE ANY TABLE.
DATA tabkind(1) TYPE c.
DESCRIBE TABLE itab KIND tabkind.
IF tabkind = sydes_kind-standard OR
     tabkind = sydes_kind-hashed.
    SORT itab DESCENDING.
ELSEIF tabkind = sydes_kind-sorted.
    MESSAGE '...' TYPE 'E'.
ELSE.
    MESSAGE '...' TYPE 'E'.
ENDIF.
ENDFORM.
DESCRIBE FIELD INTO
Note
This statement is for internal use only.
It cannot be used in application programs.
Syntax
DESCRIBE FIELD dobj INTO td.
Effect
All characteristics of the field f, its components , sub-components etc. are displayed in the field td (type description). td has to be of the type SYDES_DESC, defined in Type Group SYDES. Because of this, the type group SYDES must be integrated into the ABAP-program with a TYPE-POOLS statement .
The structure SYDES_DESC has two table-type components TYPES and NAMES:
In TYPES, the tree structure of the type belonging to f is displayed. The components of a node are stored in the table TYPES in a continuous manner. Beginning and end of the line area that represents the components are stored in TYPES-FROM and TYPES-TO. The reference to the superior node can be found in TYPES-BACK. If no superior resp. subordinate node exists, then this is marked by the value 0 (For the relevance of further components, refer to the following sections).
The names of components, types etc. are not stored directly in TYPES. Instead, the components TYPES-IDX_... hold an index in the name table NAMES. The value 0 indicates that there is no reference to the name table.
NAMES contains the possibly fragmented names in the component NAMES-NAME. If a name continues in the following line, this is indicated by an asterisk ('*') in the component NAMES-CONTINUE.
The type description table (TYPES) not only stores information about the tree structure but also further information about the type of f resp. its components. This includes especially all information that can be determined using the usual additions to DESCRIBE FIELD. In detail, TYPES contains the following columns:
IDX_NAME
Component Name
IDX_USER_TYPE
Name of a user-defined type, i.e., a type that was defined through its TYPES-statement. Derived types (... TYPE A-B) and structures from the ABAP-Dictionary are not considered to be user-defined types.
CONTEXT
For user-defined types only: The context, in which the type is defined. Possible values are defined in the constant SYDES_CONTEXT of the type group SYDES. Please only use these constants to carry out a comparison. In detail, we distinguish between the following type contexts:
SYDES_CONTEXT-PROGRAM: Program-global type
SYDES_CONTEXT-FORM   : FORM-local type
SYDES_CONTEXT-FUNCTION: FUNCTION-local type
SYDES_CONTEXT-METHOD : METHOD-local type
IDX_CONTEXT_NAME
For user-defined types only:
With a local context: The name of the FORM or FUNCTION, whose type was defined. The name of the associated program is then the first entry in the name table.
With a global context: The name of the program in which the type was defined.
IDX_EDIT_MASK
Conversion routine from the ABAP-Dictionary, is in accordance with the addition EDIT MASK at simple DESCRIBE.
IDX_HELP_ID
Help-Id when referencing to fields from the ABAP-Dictionary
LENGTH
Internal length, corresponds to the addition LENGTH at simple DESCRIBE
OUTPUT_LENGTH
Output length, corresponds to the addition OUTPUT-LENGTH at simple DESCRIBE
DECIMALS
Number of decimal digits, corresponds to the addition DECIMALS at simple DESCRIBE
TYPE
ABAP-Type, corresponds to the addition TYPE at simple DESCRIBE
TABLE_KIND
A table type is stored here for the components which represent an internal table. The same values are returned as with the variant DESCRIBE TABLE itab KIND k. Components which do not represent a table get the return value set to SYDES_KIND-UNDEFINED (see type group SYDES).
Example
Example definition of the complex data type EMPLOYEE_STRUC:
PROGRAM DESCTEST.
TYPES: BEGIN OF name_struc,
         first TYPE c LENGTH 20,
         last   TYPE c LENGTH 20,
       END OF name_struc,
       BEGIN OF absence_time_struc,
         day        TYPE d,
         from       TYPE t,
         to         TYPE t,
       END OF absence_time_struc,
       phone_number TYPE n LENGTH 20,
       BEGIN OF employee_struc,
         id         LIKE sbook-customid,
         name       TYPE name_struc,
         BEGIN OF address,
           street TYPE c LENGTH 30,
           zipcode TYPE n LENGTH 4,
           place   TYPE c LENGTH 30,
         END OF address,
         salary_per_month TYPE p LENGTH 10 DECIMALS 3,
         absent           TYPE STANDARD TABLE OF absence_time_struc
                               WITH NON-UNIQUE DEFAULT KEY,
         phone            TYPE STANDARD TABLE OF phone_number
                               WITH NON-UNIQUE DEFAULT KEY,
       END OF employee_struc.
You can determine the structure of the type EMPLOYEE_STRUC by collecting the type group SYDES as follows:
TYPE-POOLS: sydes.
DATA: employee TYPE employee_struc,
      td       TYPE sydes_desc.
DESCRIBE FIELD employee INTO td.
The following table shows a few selected columns of the type description table TD-TYPES. For a better overview, the names of the columns IDX_NAME, IDX_UERR_TYPE and IDX_EDIT_MASK have been shortened:
    |FROM| TO |BACK|NAME|UTYP|EMSK|TYPE
|--||||||--
1 | 2 | 7 | 0 | 0 | 2 | 0 | v
2 | 0 | 0 | 1 | 6 | 0 | 4 | N

16 | 0 | 0 | 13 | 22 | 0 | 0 | T
17 | 0 | 0 | 7 | 0 | 0 | 0 | N
Please note that the entries in rows 6 and 7 represent internal tables (ABAP-Type h). There is always an entry for the corresponding row type (rows 13 and 17) to an internal table.
The indices in the rows 5 to 7 refer to entries in the name table TD-NAMES. If you look, e.g., at row 3, you find the corresponding component name in TD-NAMES from row 7 (NAME) onward and the corresponding user type from row 5 (NAME_STRUC) onward.
In the name table TD-NAMES you find the following entries. Note that the names SALARY_PER_MONTH and ABSENCE_TIME_STRUC are stored in two parts:
    |CONTINUE|NAME                   |CONTINUE|NAME
|--|     -||--
1 |        |DESCTEST            12 |        |PHONE

Equivalent of DB2 functions in ORACLE 11g

Hi,
I am trying to convert the SQL queries written in DB2 to ORACLE. There are some db2 specific functions are used in the queries.I am not able to find the equivalent function in ORACLE. The function names are written below:
1) DateDD()
2) SELECT @@IDENTITY
3) SELECT *
FROM (
SELECT ROWNUMBER() OVER() AS rowId_1, INNER_TABLE.*
FROM (----)as innertable
) AS Outertable
Error is: ROWNUMBER is INVALID identifier.
4) DAYOFWEEK()
5) DAYS()
6) dayofyear()
Please help me in finding the equivalent function in ORACLE.
Thanks in advance!!

You probably don't need a DateAdd function in Oracle. You can add a number to a date in Oracle-- that adds the number of days to the date.
SELECT sysdate today, sysdate+1 tomorrow
FROM dualWhy are you using DAYS()? If, as in the example, you're just trying to determine the number of days between two dates, you can subtract dates in Oracle and the difference will be a number of days (including a fractional component if applicable)
SELECT date '2011-09-27' - date '2011-09-25' difference_in_days
FROM dualIf you really need the number of days since January 1, 0001, you could subtract the date from Jan 1, 0001, i.e.
SELECT date '2011-09-27' - date '0001-01-01'
FROM dualI would assume that Oracle and DB2 would return the same number but there could well be some differences since the current calendar didn't exist in the year 1 and I know there were issues in the transition from the Gregorian to the Julian calendar where some days were decreed not to exist. It wouldn't shock me if Oracle and DB2 counted some of the days in the 1500's differently.

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'?

Can I call MS Excel Function in Oracle

Hi everyone,
I prototyped my application in Microsoft Excel. In this prototype, I'm using the BETADIST() function, which returns the cumulative beta probability density function. And, yes, if you're like me, and not a statistician, it's pretty crazy. Just for fun, check out the wikipedia page on it, and you'll see what I mean. Anyway, so now, I'm trying to perform the same functionality as that function in my Oracle APEX 4.0/Oracle 10g-R2 app.
I've studied this function a bunch, and I couldn't find an equivalent function in Oracle to do what this function does. CUME_DIST... nope, DBMS_STATS_FUNC... nope. So, I assumed I would need to figure out what exactly the function does and basically rewirte it in Oracle using PL/SQL. I've already got questions out on Statistics and Excel forums trying to figure that out.
But, before I go any further and reinvent the wheel by coding out the logic embedded in this function (which is very hairy, of course), I wanted to check with you all and see if there's a way to invoke this MS Excel function through Oracle. Not sure if an external procedure can get to an Excel library, or how to do it if it can.
Any ideas?
Thanks!
Mark

I'm pretty sure this BETADIST exists in Java already.Not natively I think.
But one can download Cern's COLT Libraries for High Performance Scientific and Technical Computing in Java.
Loading the libraries via loadjava
loadjava -user michael/xxxx@oracle_server:1521:oracle_sid -verbose -force -order -resolve -thin colt.jar concurrent.jarand creating a function
create or replace function betadist (alpha number, beta number, c number)
     return number
as
     language java
     name 'cern.jet.stat.Gamma.incompleteBeta(double, double, double) return double';
/is rather straightforward.
Calling it
SQL> select betadist(4,5,0.4) from dual
BETADIST(4,5,0.4)
         ,4059136
1 row selected.the result coincides quite well with the example given in http://www.excelfunctions.net/Excel-Beta-Dist-Function.html.
