RE: Finding Special Characters in Oracle Column

This does not work for me too.
I have Toad 9.7.2.5 and oracle 10g DB.
select 1 FROM DUAL where regexp_like ('ABC'||chr(9)||'DEF','[\t~*>]');

However, this trick works ( Thanks to Nate Schroeder )
select 1 FROM DUAL where regexp_like ('ABC'||chr(9)||'DEF','['||chr(9)||'~*>]');
Thanks,
Shiva.

Huh! It doesn't, for me. Toad 11.0 (or SQL*Plus), Oracle 11.2.0.2.0.

The following returns one row for me, in TOAD:

select 1 FROM DUAL where regexp_like ('ABC'||chr(9)||'DEF','[\t~*>]');

Hi Dennis ... Here is some sample query to test with.


select 1 FROM DUAL where regexp_like ('ABC'||chr(9)||'DEF',chr(9));  -- Works
select 1 FROM DUAL where regexp_like ('ABC'||'~'||'DEF','[~*>]'); -- Works

I want to combine these two.

select 1 FROM DUAL where regexp_like ('ABC'||chr(9)||'~*'||'DEF','[\t]'); --Does not work.

Sorry, I had nothing with which to test it; I wasn't the one with the problem.  Else my response would have been something like: "This works for me."

You might get by with pressing TAB after the [ character - that's worked for me in the past (in UNIX, though).  But that's horrible methodology from a documentation perspective, and TOAD - or something else - may manipulate that kind of tab.  But if it's a one-off, might be worth a try.

Everything I've read says that \t should work as a regex replacement for TAB.  But that's the beauty of standards: there are so many from which to choose.

Last thought on this: If you're doing this in an environment that can monkey with your \t (such as a shell command line), you may need to escape it like \\t<file:///\\t>

 No it does not.
Did you test it ?

 This doesn't work for you?

select * from seasons where regexp_like (season_desc,'[\t~>*]');
 or
 select * from seasons where regexp_like (season_desc,'[\9~>*]');

Hi Folks ... I want to find all the records in a table( Oracle 10g)  which has TAB,~,>,* in a VARCHAR2 column.

I can do it in two separate query using regexp_like.
But I am not able to do it in one query using regexp_like.

select * from seasons where regexp_like (season_desc,'[~>*]');
select * from seasons where regexp_like (season_desc,chr(9));

Can you help me do so.

Thanks,
Shiva.
