Replace strings in SQL

On occasion, I need to replace strings in entire database columns.

Here is how to do it in MySQL (reference link1 link2):

UPDATE
    table_name
SET
    column_name = REPLACE(column_name, 'text to find', 'text to replace with')
WHERE
    column_name LIKE '%text to find%';

Here is how to do it in SQL Server (reference link):

update my_table
set path = replace(path, 'oldstring', 'newstring')
