I m looking for a way to update just a portion of a string via MySQL query.
For example, if I have 10 records all containing string as part of the field value, is there a way to change string to anothervalue for each row via one query?
I.e. for the following:
Change something/string, something/stringlookhere, something/string/etcetera to
something/anothervalue, something/anothervaluelookhere, something/string/etcetera
I think this should work:
UPDATE table
SET field = REPLACE(field, string , anothervalue )
WHERE field LIKE %string% ;
UPDATE `table` SET `field` = REPLACE(`field`, string , anothervalue )
Use the LIKE operator to find the rows that you care about and update them using the REPLACE function.
For example:
UPDATE table_name SET field_name = REPLACE(field_name, search , replace ) WHERE field_name LIKE %some_value%
