MySQL string replace

Question

I have a column containing urls (id, url):

http://www.example.com/articles/updates/43
http://www.example.com/articles/updates/866
http://www.example.com/arti         


        

Answer 1

You can simply use replace() function,

with where clause-

update tabelName set columnName=REPLACE(columnName,'from','to') where condition;

without where clause-

update tabelName set columnName=REPLACE(columnName,'from','to');

Note: The above query if for update records directly in table, if you want on select query and the data should not be affected in table then can use the following query-

select REPLACE(columnName,'from','to') as updateRecord;
