SUBSTR and INSTR function

Hi Gurus,
I have the data as follows:
data
'BIDIE01H/TXT:ZUNE=HA011, CellIndex=144 /CAI:452-01-32201-47001/CAI:45201F7dc9b79a'
'BIDIE01H/TXT:ZUNE=HA111, CellIndex=124 /CAI:452-01-32201-471/CAI:45201F7dc9b79b'
and I am trying to write a SQL to get the results:
CAI
452-01-32201-47001
452-01-32201-471
Any idea to get it done? I did try around with SUBSTR and INSTR functions but not yet sucessed.
Thanks,
Alex

ClarkC,
Here just replace procedure1 and procedure2 with your procedure names;
create table temp_table

insert into temp_table values ('TESTME.MY_OBJECTS');
insert into temp_table values ('TESTME.OBJECTS');
insert into temp_table values ('ABC.ECFOBJECTLOG');

insert into temp_table values ('ABC.ABCTABLE');
insert into temp_table values ('ZYD.CLIENTTABLE');
insert into temp_table values ('NMS.CLIENTLOGTABLE');
COMMIT;
pl/sql anonymous blocks I defined 2 variables for readibility and understanding

      my_table     := NULL;
      my_table     := cur.table_name;
      table_name   := SUBSTR (my_table, INSTR (my_table, '.') + 1);
      IF (table_name LIKE ('%OBJ%'))
      THEN
         DBMS_OUTPUT.put_line ('table_name containing OBJ=' || table_name);
         -- NOTE : CALL YOUR PROCEDURE1 HERE for tables containing OBJ;
        procedure1(table_name);
      ELSE

SUBSTR and INSTR query

Hello all,
I need help in simple query how can show only MCCODE
SELECT SUBSTR('VMTOPIC=MCCODE', INSTR('VMTOPIC=MCODE', 'VMTOPIC=')+8,20) AS output FROM DUAL;But also when i used
SELECT SUBSTR('VMTOPIC=MCCODE', INSTR('VMTOPIC=MCODE', 'HHH')+8,20) AS output FROM DUAL;show same results, what i need only if words begin with " VMTOPIC= " retrived characters after "VMTOPIC=".
regards
Dheya

Hi, Dheya,
Here's one way:
SELECT SUBSTR ( str
            , INSTR ( str || 'VMTOPIC='
                        , 'VMTOPIC='
                 ) + 8
            , 20    -- or omit this argument
            )       AS output
FROM    table_x
;where tabe_x.str is the string you need to test.
You could also do this with REGEXP_SUBSTR or REGEXP_REPLACE, but you can do this easily enough without any slow regular expressions.

SELECT SUBSTR('VMTOPIC=MCCODE', INSTR('VMTOPIC=MCODE', 'HHH')+8,20) AS output FROM DUAL;show same results, what i need only if words begin with " VMTOPIC= " retrived characters after "VMTOPIC=".That's because 'HHH' wasn't found, and so INSTR returned 0. SUBSTR treats 0 like 1 in its 2nd argument, so, using that expresssion, not fnding the string is te same as finding it at position 1.
Of couse, looking for 'HHH' in a string that cotains 'VMTOPIC=' isn't the problem here; the real problem is looking for 'VMTOPIC=' in a string that doesn't contain it.
Making a special case when INSTR returns 0, as Solomon suggested, is one way to get around the problem. Another is what I posted above, which guarantees that INSTR will never return 0. If the 'VMTOPIC=' is not found in str, then lookng for it in str || 'VMTOPIC=' will cause INSTR to return a very high number; so high that SUBSTR will then return NULL.
I hope this answers your question.
If not, post CREATE TABLE and INSERT statements for a little sample data (maybe 5 rows), and the results you want from that data.
Point out where the query above is producing the wrong results, and explain, using specific examples, how you get those results from the sample data in those places.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).

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.

How to make an substr and instr combination in javascrip

Dear all,
I need to extract some information in a javascript function.
In sql we can do like this substr(:P1_ITEM, 1, instr(:P1_ITEM,'.',1,4)-1)
f.e.
01.02.03.04.05 --> 01.02.03.04
001.002.003.004.005 --> 001.002.003.004
How I can do it in javascript.
Thanks in Advance
lukx

Hi lukx,
You can use the following javascript function:
function processText(pString, pSearchString, pOccurrenceNum)
var j = 0;
for(var i = 0; i < pOccurrenceNum; i++)
j = pString.indexOf(pSearchString,j) + 1;
j = j - 1;
return pString.substr(0,j);
}To process, for example, the second example you showed, you would have to do the following call:
processText("001.002.003.004.005", ".", 4)Maybe this is not the best solution but as I've seen in the javascript API that indexOf and lastIndexOf are only for the first and last occurrence, that's why I included the for loop. Hope this helps.

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.

Substr and instr

Have a look at this 'blk_employee_detail',
Now what i want to do is, remove the blk prefix and also the '_'.
and return employee detail.
dipin

Thank you a lot,
That works but i doubt it for forms.
Since you are trying to help me i think i shud write the whole scenario to you.
Here it goes.
I have got a number of blocks named starting with 'blk_..'.
and i need to display the block name on a display item using system.current_block.
But that would display me the real block name, the name i had kept for the block.
SO my problem is to format the block name,for example removing the 'blk_' and if there are some underscores in between the names then they too need to be removed.
Now i think the problem is crystal clear to you, buddy.
Thanx a lot.

Dynamic PL/SQL & substr, instr function

I am having trouble with incorporating the SUBSTR and INSTR functions into my dynamic PL/SQL procedure using Oracle 8i.
I have data that is packed into one column seperated by a delimiter (':')
I need to seperate the data to use indicidual pieces.
If I run my query in general -
select substr(secondcol, 1, instr(secondcol, ':',1,1)-1) ONE,
substr(secondcol,instr(secondcol, ':',1,1)+1,instr(secondcol, ':',1,1)-1) TWO,
substr(secondcol,instr(secondcol, ':',1,2)+1,instr(secondcol, ':',1,1)-1) THREE,
substr(secondcol,instr(secondcol, ':',1,3)+1,instr(secondcol, ':',1,1)-1) FOUR
from temp_table where firstcol=100
This works and gives me the right result.
e.g
DATA :
Firstcol SECONDCOL
100 1:2:3:4
Result:
ONE TWO THREE FOUR
1 2 3 4
However to make this generic if I use it in a function passing it a parameter which has ':' delimited data it does not work and gives me errors. All I want is to get the output as a string that looks like my query above so I can use it in my proc.
create or replace function MYJUNK(TFieldNew IN CHAR)
RETURN CHAR IS
UpdateString Varchar2(100);
BEGIN
UpdateString := 'First=substr('||TFieldNew||', 1, instr('||TFieldNew||', '':'',1,1)-1) ONE, ';
UpdateString := UpdateString || ' Second=substr('||TFieldNew||', instr('||TFieldNew||', '':'',1,2)+1, instr('||TFieldNew||', '':'',1,1)-1) TWO, ';
UpdateString := UpdateString || ' third=substr('||TFieldNew||', instr('||TFieldNew||', '':'',1,3)+1, instr('||TFieldNew||', '':'',1,1)-1) THREE from temp_table';
return UpdateString;
END;
The function compiles but gives me run time errors
This is what I get -
SQL> select myjunk('''1:2:3:4''') from dual;
select myjunk('''1:2:3:4''') from dual
ERROR at line 1:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "SGHDTA.MYJUNK", line 8
ORA-06512: at line 1

You are getting an error because updatestring is longer than the 100 characters you defined it as. Try using VARCHAR2(4000). Also, if you are trying to generate the sql statement, you need to get rid of first=, second= and third= when you build the string.
This is what your function returns. I put in line breaks for clarity:

from temp_tableIf you are trying to actually parse the column, then you need something more like:
create or replace procedure MYJUNK(TFieldNew IN VARCHAR2,out1 OUT VARCHAR2,
                                   out2 OUT VARCHAR2, out3 OUT VARCHAR2) is
BEGIN
   out1 := SUBSTR(TFieldNew,1, INSTR(TFieldNew,':',1,1)-1);
   out2 := SUBSTR(TFieldNew, INSTR(TFieldNew,':',1,2)+1, INSTR(TFieldNew,':',1,1)-1);
   out3 := SUBSTR(, INSTR(TFieldNew,':',1,3)+1, INSTR(TFieldNew,':',1,1)-1);
END;
