MySQL has a handy and simple string function REPLACE() that allows table data with the matching string to be replaced by new string. This is useful if there is need to search and replace a text string which affects many records or rows, such as change of address, company name, URL or spelling mistake.
- -- 1st example
- UPDATE files SET filepath = REPLACE(filepath,'path/to/search','path/to/replace');
- -- 2nd example
- UPDATE customers SET address = REPLACE(address,'_CODE_',postcode);
