Обсуждение: Like with special character

Hello,

I'm using postGre with tables which contain French character (éèçàù...). 
Is there a fonction which performs a like in replacing é (e cute) by e ?

thanks...

select translate('forêt', 'àâäéèêëîïôöùûü', 'aaaeeeeiioouuu');

Change the first word (forêt) by the string you want characters to be
replaced.

For more, see : http://docs.postgresqlfr.org/pgsql-8.1.3-fr/functions-string.html   (french docs)
http://www.postgresql.org/docs/8.1/interactive/functions-string.html  (english docs)
 

BTW, it is PostgreSQL, not postGre.

Perfect, thanks

I found regex for postgreSql too, it's interesting too

select * from divers
where s_libelle ~* '^t(e|é|ê)'

I got the following error:

select to_ascii('ê');
ERROR:  encoding conversion from UNICODE to ASCII not supported

Some comments about it.
