This topic describes the support of data migration or synchronization projects of different data source types for DDL statements related to tables and indexes.
Considerations
This topic does not cover all specific scenarios, such as all options of
ALTER TABLE ADD COLUMN
, due to the complexity of DDL statements. For any unsupported scenarios, take actions as prompted or contact OceanBase Technical Support.The DDL statements listed in this topic are only for your reference. The actual syntax varies slightly based on the database. Therefore, you must determine the supported DDL statements for synchronization based on the statement syntax of your database.
The
CREATE
DDL statements listed in this topic will be synchronized to the destination only if objects are selected by using the Match Rules option and the names of tables created by using theCREATE
statements match the migration object rules.The
RENAME
DDL statements listed in this topic will be synchronized to the destination only if objects are selected by using the Match Rules option and the names of tables renamed by using theRENAME
statement match the migration object rules.The index-related DDL statements listed in this topic will be synchronized to the destination only if the names of tables where the indexes belong match the migration object rules.
For the support status of DDL statements in reverse incremental migration in a data migration project, see the corresponding section in this topic based on the data source types in the order of "destination->source". For example, for the support status DDL statements in reverse incremental migration in a data migration project whose source is a MySQL database and destination is a MySQL tenant of OceanBase database, see the OB_MySQL -> MySQL section of this topic.
