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

The replace function should work for you   REPLACE str from str to str    Returns the string str with all occurrences of the string from str replaced by the string to str  REPLACE   performs a case-sensitive match when searching for from str

UPDATE your table SET your field   REPLACE your field   articles updates     articles news    WHERE your field LIKE   articles updates      Now rows that were like   http   www example com articles updates 43   will be   http   www example com articles news 43  http   www electrictoolbox com mysql-find-replace-text

In addition to gmaggio s answer if you need to dynamically REPLACE and UPDATE according to another column you can do for example   UPDATE your table t1 INNER JOIN other table t2 ON t1 field id   t2 field id SET t1 your field   IF LOCATE  articles updates    t1 your field   gt  0   REPLACE t1 your field   articles updates    t2 new folder   t1 your field   WHERE      In my example the string articles news  is stored in other table t2 and there is no need to use LIKE in the WHERE clause
