Checking the Additional Column of the Destination Database

Check whether the additional column is added to the additional column list of the destination database. If no additional column is added, the incremental synchronization task fails.

Failure Cause

Some columns are missing in the additional column processing table in the destination database.

Handling Suggestion

Add the missing additional columns to the destination database tables. Reference statement:

ALTER TABLE ` database `.` table ` ADD COLUMN ` column_name ` column_definition;
