MySql - Way to update portion of a string?

Question

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

Answer 1

Does something like this work in any way?

update table_name
set column_name = replace(column_name, 'string%', 'string') 
where column_name like '%string%'

Answer 2

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%'

Answer 3

UPDATE `table` SET `field` = REPLACE(`field`, 'string', 'anothervalue')

Answer 4

I think this should work:

UPDATE table
SET field = REPLACE(field, 'string', 'anothervalue')
WHERE field LIKE '%string%';
