SELECT Records based on octal or decimal value at the end of a string

I need to select records from a table if they have a certain decimal value at the end of the string.  After an import we get many records that contain decimal value 13 as the final character.  I determined that based on doing a dump in PL/SQL.

select '('||website||')', dump(website)
from business
----------

I get the following:
(sunshinecavaliers.com ), Typ=1 Len=22:115,117,110,115,104,105,110,101,99,97,118,97,108,105,101,114,115,46,99,111,109,13

Now, that I know my problem records contain a decimal value of '13' I want to search my entire DB to find all records that contain the '13' at the end of the website field.

decimal character 13 is a carriage return rather than searching on the dump output
just search for that character



select '('||website||')', dump(website)
from business
where website like '%' || chr(13)


note, looking for trailing characters is not normally going to be something you can use an index, so this query might take a while if you have many rows

>>>  instr(website,chr(13)) = length(website);

same idea as LIKE '%' ||13 but more expensive to execute

I agree and wouldn't have even posted my suggestion except I wrote it much earlier but never submitted it after I received a phone call and never even saw the other responses. I was going to withdraw it, but apparently cannot after a new comment has been submitted. You're just too fast, Sean :-)

It works great.  Unfortunately I have far more records with problems than I thought.  I should be able to update those records and simply remove the chr(13) though right?

doing the update is easy, but only you can decide if it's ok to do so or not.

update business
set website = rtrim(website,chr(13))
where website like '%' || chr(13)
