Find and Replace in SQL database

If you need to find and replace a small portion of code (such as ~<username> to <url>) in a database you can use something like:

[sql,n] update [table_name] set [field_name] = replace([field_name],'[string_to_find]','[string_to_replace]');

Just make sure [field_name] is set correctly on both sides. Otherwise you may overwrite data.
