Replace string using mysql's replace function

I have been researching CMS recently and I need to use MySQL’s replace function when converting data. Here is a brief introduction!

For example, if you want to replace abc in the f1 field in table tb1 with def

UPDATE tb1 SET f1=REPLACE(f1, 'abc', 'def');

REPLACE(str,from_str,to_str)
In the characters All occurrences of the string from_str in the string str are replaced by to_str, and then this string is returned: SELECT REPLACE('www.mysql.com', 'w', 'Ww'); -> ; 'WwWwWw. mysql.com'
This function is multi-byte safe.

Example:
UPDATE `dede_addonarticle` SET body = REPLACE ( body,
'',
'' );
UPDATE `dede_addonarticle` SET body = REPLACE ( body,
'' ,
'' );
UPDATE `dede_addonarticle` SET body = REPLACE ( body,
'',
'' );
UPDATE `dede_archives` SET title= REPLACE ( title,
'Dayang News- ',
'' );
UPDATE `dede_addonarticle` SET body = REPLACE ( body,
'../../../../../../',
'http://special.dayoo.com /meal/' );

mysql replace
