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

update mytable set title=trim(replace(REPLACE(title,CHAR(13),''),CHAR(10),''));

Above is working for fine.

UPDATE test SET log = REPLACE(REPLACE(log, '\r', ''), '\n', '');

worked for me.

while its similar, it'll also get rid of \r\n

your syntax is wrong:

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

Addition:

If the newline character is at the start of the field:

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

1) Replace all new line and tab characters with spaces.

2) Remove all leading and trailing spaces.

 UPDATE mytable SET `title` = TRIM(REPLACE(REPLACE(REPLACE(`title`, '\n', ' '), '\r', ' '), '\t', ' '));
