I still don't understand why it is so complicated..
your problem: my task is to find whether the particular string is present or not
lets consider the following scenario.
1. you want the exact match.
select col_name from table1
where col_name='WOGENRESOUR';
2. the string 'WOGENRESOUR' can be present in any place in the column data
select substr(col_name,instr(col_
where instr(col_name,'WOGENRESOU
3. the string 'WOGENRESOUR' should be at the start in the column
select substr(col_name,1,length('
where instr(col_name,'WOGENRESOU
or
select substr(col_name,1,length('
where col_name like 'WOGENRESOUR%';
I hope this will resolve all your queries... just try it on your data depending on what scenario you are looking for. I think you are looking for scenario 3.
cheers,
Ajay
here is the example for your reference:
SQL> create table sampletable (col varchar2(100));
Table created.
SQL> insert into sampletable values ('WOGENRESOURC');
1 row created.
SQL> insert into sampletable values ('WOGENRESOUR1');
1 row created.
SQL> insert into sampletable values ('othervalue');
1 row created.
SQL> commit;
Commit complete.
SQL> select col
2 from sampletable
3 where instr(col,'WOGENRESOUR') = 1;
COL
--------------------------
WOGENRESOURC
WOGENRESOUR1
SQL>
With this test data:
insert into sampletable values ('WOGENRESOURC');
insert into sampletable values ('WOGENRESOUR1');
Your query produces:
COL
------------
WOGENRESOURC
WOGENRESOUR1
I meant to use TRANSLATE, not SUBSTITUTE in my query above, and I think he wants:
select 'WOGENRESOUR' as col
from sampletable
where translate(col,'.0123456789
COL
-----------
WOGENRESOUR
He gave the example as:
>here the table1 has
> WOGENRESOURC
>
>this data is not the same as WOGENRESOUR but it retruning this value i can also add the conditon
So, he does NOT want to return WOGENRESOURC. He adds a condition to eliminate this from his results:
>length(col_name)=length('
But then this will not be selected:
>WOGENRESOUR1
So if you have a table with
WOGENRESOUR
WOGENRESOURC
WOGENRESOUR1
it appears he only wants the first and third entry.
>you already know "WOGENRESOUR", why you bother to "GET" "WOGENRESOUR"?
Because his select was:
substr(col_name,1,length('
That will always resolve to WOGENRESOUR, so I decided to eliminate the function.
