Actually, executing select from information_schema.placement_policies
and show create table
resulted in errors. I suggest copying this show create table
statement and executing it in TiDB to see if the same error occurs.
Additionally, your dumping version is 7.1.0, but I see that your database version is 4.0.16. It seems like there is a version mismatch between the tool and the database. Some SQL statements that work fine in the new version may cause errors in the old version.
Because placement_policies
is likely a new feature introduced in version 5.0, it might be true that this table cannot be found in the 4.0 database.
