Checking Whether the Databases and Tables Exist
Check whether the task objects meet the migration or synchronization requirements.
Failure Cause
- During object file import, there are databases and tables that do not exist in the source database. The synchronization fails.
- The selected tables contain identifier columns, but the destination database does not support identifier columns. As a result, data synchronization fails.
Handling Suggestion
- Remove these objects that do not exist in the source database and import the file again.
- Click Previous to return to the object selection page and deselect the tables containing identifier columns.
