How to remove new line characters from data rows in mysql?

Question

I can loop through all of the rows in a php script and do

UPDATE mytable SET title = "'.trim($row['title']).'" where id = "'.$row['id'].'";

and trim can remove \n

But I was just wondering if something same could be done in one query?

 update mytable SET title = TRIM(title, '\n') where 1=1

will it work? I can then just execute this query without requiring to loop through!

thanks

(PS: I could test it but table is quite large and dont want to mess with data, so just thought if you have tested something like this before)

Answer 1

your syntax is wrong:

update mytable SET title = TRIM(TRAILING '\n' FROM title)

Answer 2

UPDATE mytable SET title=TRIM(REPLACE(REPLACE(title, "\n", ""), "\t", ""));
