I also encountered the same issue, so I debugged the code. I found that in the `performTablesMigration` method of the `GroupedSchemaMigratorImpl` class, when calling `final NameSpaceTablesInformation tables = existingDatabase.getTablesInformation(namespace);` it failed to retrieve the tables. so resulted in the creation of new tables. Upon further investigation, I noticed that the `currentCatalog` field in the `JdbcEnvironmentImpl` was empty. This caused the `AbstractInformationExtractorImpl` to be unable to retrieve table information when calling `getTable`. The root cause of the issue appears to be that the `ShardingSphereConnection` class's `getCatalog` method is returning null. I'm using Hibernate version 6.2.5 and ShardingSphere version 5.3.2. -- This is an automated message from the Apache Git Service.
