Convert old temporal types on ALTER TABLE ... FORCE

    XMLWordPrintable

Details

    Description

      MySQL 5.6 converts temporal types to the new sub-second-enabled type on ALTER TABLE ... FORCE (while original old types are kept when doing ALTER TABLE ... ENGINE=..., and even on CREATE TABLE ... LIKE)

      MariaDB doesn't touch temporal types on ALTER TABLE ... FORCE though, here some explicit change to the table structure is needed to force a change to the new temporal implementation instead, e.g. a ADD COULUMN or MODIFY COLUMN.

      The MySQL implementation of the operation was added with the following change set:
