问题:

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 (i.e., 'something/string', 'something/stringlookhere', 'something/string/etcetera', is there a way to change 'string' to 'anothervalue' for each row via one query, so that the result is 'something/anothervalue', 'something/anothervaluelookhere', 'something/string/etcetera', is there a way to change 'anothervalue'

回答1:

I think this should work:

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


回答2:

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


回答3:

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%'
