Note: In the above variable i see 8 transactions, where as in real scenario i donot how many transaction i may recive.
after modification i need above transactions should in below format
ALTR Varchar2(2000):=('12ERE-3MT-4Y','4IT-5O-SD','OP-K5-456','P04-SFS9-098','90P-SSF-334','3434-KJ4-O28','AS3-SFS0-J33','989-3KL-3434');

create or replace type myTableType as table of varchar2(255)
declare

v_new_str varchar2(4000);
function str2tbl
         (p_str   in varchar2,

    begin
        loop
            l_n := instr( l_str, p_delim );
            exit when (nvl(l_n,0) = 0);
            l_data.extend;
            l_data( l_data.count ) := ltrim(rtrim(substr(l_str,1,l_n-1)));
            l_str := substr( l_str, l_n+length(p_delim) );
        end loop;
        return l_data;
   end;
begin
v_array := str2tbl ('12ERE-3MT-4Y,4IT-5O-SD,OP-K5-456,P04-SFS9-098,90P-SSF-334,3434-KJ4-O28,AS3-SFS0-J33,989-3KL-3434', ',');
      FOR i IN 1 .. v_array.COUNT LOOP

   dbms_output.put_line(RTRIM(v_new_str, ','));

Spliting Column with a Substring and Charindex

I have a column in my database that stores title, first name and last name. But data in this column is not clean as sometimes, the customer's title is missing or null, other time the first name is not available and some other time, the last name is
void. Now, I want to separate or split the column into three - Title, FirstName, LastName bearing in mind that I have to check for nulls or empty data. How do I clean this data so that errors like:
Msg 536, Level 16, State 2, Line 1
Invalid length parameter passed to the RIGHT function.
or
Msg 537, Level 16, State 2, Line 1
Invalid length parameter passed to the LEFT or SUBSTRING function.
are not returned.
I wrote a script like this but not good enough.
SELECT FullName
, LEFT(FullName, ISNULL(NULLIF(CHARINDEX(' ', FullName) - 1, -1), LEN(FullName))) AS Title
, RIGHT(Salute, LEN(Salute) - CHARINDEX(' ', FullName, 1)) FirstName
, SUBSTRING(FullName, 1, CHARINDEX(' ', FullName, 19) - 1) LastName
FROM Details
If we have a title and a name, we should split into 'Title', 'FirstName'. If no title, we will treat it as 'FirstName' and 'LastName'
Thank you!

Using Substr and Instr together

Hi All,
I have a string like 'Employee_id,employee_name,employee_ssn,employee_ps'
I would like to extract all the four columns individually in a single statement.
For ex:
select SUBSTR('Employee_id,employee_name,employee_ssn,employee_ps',1,
INSTR('Employee_id,employee_name,employee_ssn,employee_ps',',',1,1)-1) from dual;
this gives me Employee_id. The same way how do i get the other coulmn names by comma position.
Pls help me out.
Please note that the column names have to be extracted depending on the comma position.
Thanks.

You can use regular expressions if you're running an Oracle version that's 10g or more recent, to make it very simple:
Connected to Oracle Database 11g Enterprise Edition Release 11.2.0.1.0
Connected as FSITJA
SQL>
SQL> select regexp_substr('Employee_id,employee_name,employee_ssn,employee_ps', '[^,]+', 1, 1) col_1,
2         regexp_substr('Employee_id,employee_name,employee_ssn,employee_ps', '[^,]+', 1, 2) col_2,
3         regexp_substr('Employee_id,employee_name,employee_ssn,employee_ps', '[^,]+', 1, 3) col_3,
4         regexp_substr('Employee_id,employee_name,employee_ssn,employee_ps', '[^,]+', 1, 4) col_4
5    from dual;
COL_1       COL_2         COL_3        COL_4

Hi,
REGEXP_REPLACE ( last_name
               , ' ((jr)|(sr))$'
               , NULL
               , 1
               , 1
               , 'i'
               )will do that, regardless of whether 'jr' or 'sr' is capitalized or not.
If you prefer a case-sensitive expression, omit the last argument. (Actually, you could omit the last four arguments ", NULL, 1, 1, 'i'").

PL-SQL Solve: Using INSTR and SUBSTR

I am trying to work on this and cannot get a solution. Please help
You have to use INSTR and SUBSTR to solve
Question:
You have the following acceptable value
Numberic: 0-34
80-100
or Non Numberic X S U D- D D+
Im have to use INSTR and SUBSTR functions to test that the value is a valid (as above) number before TO_NUMBER is called:
SELECT TO_NUMBER('?? ') //HERE ?? and a space (for 100 etc) is for the values as above
FROM DUAL
WHERE ....INSTR(......)<=;
(Hence if the number is true then number comes back or it says no rows)
and also id non numberic it should also be tested.
I am completely unsure about it but tried this
SELECT TO_NUMBER('34 ')
FROM DUAL
WHERE INSTR('0123456789',1,1)<=9 (looking at first number ?)
AND
INSTR('0123456789',2,2)<=9
AND
INSTR('0123456789',3,3)=0;
Please help

We have the following value that we can use:
Numeric: 0-34 and 80-100 only
or Non Numberic X S U D- D D+
Have to use INSTR and SUBSTR functions to test that the value is a valid
(for now only trying to create a function which can later be put into a procedure.)
SELECT TO_NUMBER('12 ') //e.g HERE 12 and a space for the values as above
FROM DUAL
the where clause looks at all three spaces to make sure values are correct (given number or non-numberic values only)
(Hence if the number is true then number comes back (meaning true)
or it says NO rows)
If value is non numeric, test it to allow non numberic also.
I am completely unsure about it but tried this
SELECT TO_NUMBER('34 ')
FROM DUAL
WHERE INSTR('0123456789',1,1)<=9 (looking at first number ?)
AND
INSTR('0123456789',2,2)<=9
AND
INSTR('0123456789',3,3)=0;
Something like this has to be done.....subst (instr, x,x,) i think mite help.

the length of the values can vary. eg the output can also be
"123,3,124567,443,1224"
I need to get each value and store it a separate variable. is it possible using substr..?
Please help me out...

Hi,
Here's how you can split a delimited list into parts in Oracle 9:
WITH     got_part_cnt     AS
     SELECT     pk
     ,     csv
     ,     1 + LENGTH (csv)
            - LENGTH (REPLACE (csv, ','))     AS part_cnt
     FROM     table_x
,     cntr     AS
     SELECT     LEVEL     AS n
     FROM     ( SELECT MAX (part_cnt)     AS max_part_cnt
            FROM       got_part_cnt
     CONNECT BY     LEVEL <= max_part_cnt
,     got_pos          AS
     SELECT     p.pk
     ,     p.csv
     ,     c.n
     ,     INSTR ( ',' || p.csv
                , 1
                , c.n
                )          AS start_pos
     ,     INSTR ( p.csv || ','
                , 1
                , c.n
                )      AS end_pos
     FROM    got_part_cnt     p
     JOIN     cntr          c     ON     c.n     <= p.part_cnt
SELECT       pk
,       csv
,       n
,       SUBSTR ( csv
             , start_pos
           , end_pos - start_pos
           )               AS item
FROM       got_pos
ORDER BY pk
,            n
;Pk is the primary key of table_x. If you don't need it, you can omit it.
Of course, this will work in versions later than 9, but you wouldn't want to if you could use REGEXP_SUBSTR.

How to use substr in external table defnition.

Hi All,
Im using oracle 11g. I have an external table which is reading data from a file. For one of the column, i need to get only the first 250 characters. My external table defnition looks like this
create table tbl_substr
( col1 varchar2(20),
col2 varchar2(250)
organization external
( type oracle_loader
default directory XXXX
access parameters (
records delimited by newline
FIELDS TERMINATED BY '|'
missing field values are null
( col1 ,
col2 "substr(:col2,1,250)"
) ) location ('file.txt') )
reject limit unlimited
But this defnition gives an error when i do select * from tbl_substr
I want to use substr in external table defnition its self and not in SELECT. Also i dont want to crete a view to solve this. If anyone has done this please help.

Using substring function with error

Hi Guys,
I have a source field with 1200 characters which need to map to multiple target segments for 132 count of this source field.
This is not a mandatory field so it sometimes come without any value.
I am using substring function to breakout the string for every 132 characters and mapped to the target segments.
There are two problems, first it seems that if source is blank, there will be error.
Second, if source field come with only eg. 300 characters, error will also occurs.
I have searched thru SDN and try some of the UDF but to no avail.
Appreciate your guidance on this problem.

SUBSTR ( str

       )Do you need to worry about not having 3 characters between the N-th comma and the next one? What if there are fewer than N commas?
I hope this answers your question.
If no, what is your question?
Does it involve reading a csv file that is not already in a table? Post a small sample file.
Does your qestion involve parsing strings that are already in a table? Post CREATE TABLE and INSERT statements.
In any case, post the exact results you want from the given data.

Substr.processFieldNames: fromConfiguration
Thanks

Hi Ram,
I think the problem is with the source file
it should be like this for your case
Substr.fieldFixedLengths: 10,10,10,10,10,10,10
Substr.fieldNames:FirstName,LastName,MiddleName,City,Place,State,Country
Sample file
FirstName LastName MiddleNameCity Place State Country
Each file length should be 10 and not like this
FirstName LastName MiddleName City Place State Country
Thanks,
Prakash

How to use substring ?

guys,
i have to get last 3 char. of the char. string.
now the problem is, the char. string is all different length. if it was the same i could use SUBSTRING formula. but in my case its all diff. and i have to get last 3 char. from the string .
what shoud i use ?

Hi Honar,
Try this
//<varname>- value whose last 3 character you want to read
Data : v_length type n length 3,
v_value_last3 like <varname> .
*****read the length of value
v_length = STRLEN( <varname> ) .
*****subtract string length index by 3 character
v_length = v_length - 3 .
*****read last 3 character of value
v_value_last3 = <varname>+v_length(3) .
v_value_last3 will have last 3 character
Please follow spaces as in code .
This will work .

(Sysdate-1) in filename using scheduler and ftp

Hello,
I'm having a little problem with BI Publisher.
What i am trying to do is use the sysdate-1 in the filename when using the scheduler in BIP.
I found out that for using the regular date there are functions like %d %m %y, so obviously the first thing i tried was using the %d-1 but that didn't work :(
Then i went looking on the internet and found the following article:
http://obiee-bip.blogspot.com/2010/05/dynamic-delivery-file-naming-in-bi.html
This mentions things like:
dd : CAST( DAYOFMONTH(NOW()) AS CHAR) ( ex, 01 - 31)
mon : CAST( SUBSTRING(MONTHNAME(NOW()) FROM 1 FOR 3) AS CHAR) (ex, Jan - Dec)
yyyy : CAST( YEAR(NOW()) AS CHAR) (ex, 2006,2010)
But when i use those in the same filename field then it just displays the string as text in the filename.
Could someone tell me what i am doing wrong, or what i need to do to make this work?
Thanks in advance
BIP version : Oracle BI Publisher 10.1.3.4.1
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bi

Hi Raafje,
Like I've already discussed in my Blog ,Using Date Expressions on Filenames of Burst Query has its own limitations. This date expression that you have tried for sysdate-1 (%d-1%m%y) will not hold good to the requirement. Anyways you can resolve the issue using other work arounds.
Method I (Using CAST and DATE Functions)
1.Previous Day -> CAST(DAYOFMONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)
2.Month of Previous Day -> CAST(MONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE ) ) AS CHAR)
3.Year of Previous Day -> CAST(YEAR(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)
Sample Code
+'ReportName'||'-'||CAST( DAYOFMONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)||'-'||CAST(MONTH(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE ) ) AS CHAR)||'-'||CAST( YEAR(TIMESTAMPADD(SQL_TSI_DAY, -1, CURRENT_DATE)) AS CHAR)||'.pdf'+
Method II (Using Server Variables)
1. Create a Dynamic Repository Variable like Previous_Date(Non-System Session variables can also be used)
2. Create a Initialization blocks
In Data Source Section - Edit Data Source and place the below query
Select TO_CHAR(SYSDATE-1,'MM/DD/YYYY')
FROM Dual (you can use any date format as required)
3. In Variable Target Section
Edit Target -
Give the Name as Previous_Date (as you created in Step1) and Enable the Radio Button as Dynamic
Place date in Default Value like '9/22/2010'
4. Now use this Repository Variable in the filename parameter of the burst query as VALUEOF("Previous_Date") for Repository Variable
and VALUEOF(NQ_SESSION.Previous_Date) in case you have created a session variable for the query
Thanks & Regards,
Goushalya
