Question

我迁移数据时发生错误我试着在下面运行原始的sql：
ALTER TABLE wxwall_participation ADD COLUMN event INT DEFAULT 0
ALTER TABLE wxwall_scene ADD COLUMN welcome_msg VARCHAR（400）NULL
它们工作得非常好，这让我很开心。我怎么能解决这个问题呢？

错误明细：

 - Migrating forwards to 0002_auto__add_field_participation_event__add_field_scene_welcome_msg.
 > wxwall:0002_auto__add_field_participation_event__add_field_scene_welcome_msg
 ! Error found during real run of migration! Aborting.

 ! Since you have a database that does not support running
 ! schema-altering statements in transactions, we have had
 ! to leave it in an interim state between migrations.

! You *might* be able to recover with:   - no dry run output for delete_foreign_key() due to dynamic DDL, sorry
   = ALTER TABLE `wxwall_participation` DROP COLUMN `event` CASCADE; []
   - no dry run output for delete_foreign_key() due to dynamic DDL, sorry
   = ALTER TABLE `wxwall_scene` DROP COLUMN `welcome_msg` CASCADE; []

 ! The South developers regret this has happened, and would
 ! like to gently persuade you to consider a slightly
 ! easier-to-deal-with DBMS (one that supports DDL transactions)
 ! NOTE: The error which caused the migration to fail is further up.

Error in migration: wxwall:0002_auto__add_field_participation_event__add_field_scene_welcome_msg

_mysql_exceptions.Warning: InnoDB: ROW_FORMAT=DYNAMIC requires innodb_file_format > Antelope.

Answer 1

我发现了问题。关键是innodb_file_format
我从生产数据库backup.Production的mysql config innodb_file_format=Barracuda恢复数据，但我的本地是默认值Antelope。

我认为更合适的错误讯息是ROW_FORMAT=DYNAMIC requires innodb_file_format =Barracuda 我该怎么做才在innodb_file_format = Barracuda中设置my.ini，然后一切都会好的。

南迁移错误，InnoDB：ROW_FORMAT = DYNAMIC需要innodb_file_format＆gt;羚羊
