The embodiment of the invention provides a DDL synchronization method and device for a V9.7 version DB2 database. The method comprises the following steps of: obtaining a target object, creating a DDLrecord auxiliary table in a source end DB2 database, starting the DATA CAPTURE CHANGES attribute of the DDL record auxiliary table, and starting the DATA CAPTURE CHANGES attribute of the DDL record auxiliary table; inserting a DDL operation in a source end DB2 database into the DDL record auxiliary table by adopting a DDL capture storage process, continuously executing the DDL capturing and storing process; starting the DATA CAPTURE CHANGES attribute of the DDL operation corresponding table, and starting the DATA CAPTURE CHANGES attribute of the DDL operation corresponding table; analyzing anINSERT operation log in the DDL record auxiliary table, extracting DDL operation information in the DDL record auxiliary table, and sending the DDL operation information to a target end data synchronization service; and extracting the DDL operation information at a target end data synchronization service, and executing the DDL operation information on a target end database to realize DDL synchronization. According to the DDL synchronization method and device for the V9.7 version DB2 database provided by the embodiment of the invention, the DDL synchronization can be realized in the data synchronization taking the V9.7 version DB2 database as the source.
