See the example above where other_field_1 is set to insert_value on INSERT or to update_value on UPDATE while other_field_2 is always set to other_value.Ĭrucial for the Insert on Duplicate Key Update (IODKU) to work is the schema containing a unique key that will signal a duplicate clash. This way, you can set different values by using INSERT and UPDATE. Sometimes, when updating on duplicate key it comes in handy to use VALUES() (opens new window) in order to access the original value that was passed to the INSERT instead of setting the value directly. This will INSERT into table_name the specified values, but if the unique key already exists, it will update the other_field_1 to have a new value. INSERT INTO `table_name ` ( `index_field `, `other_field_1 `, `other_field_2 ` ) VALUES ( 'index_value', 'insert_value', 'other_value' ) ON DUPLICATE KEY UPDATE `other_field_1 ` = 'update_value', `other_field_2 ` = VALUES ( `other_field_2 ` ) Recover and reset the default root password for MySQL 5.7+.Dynamic Un-Pivot Table using Prepared Statement.Connecting with UTF-8 Using Various Programming language.
