For objects with the same name that already exist in the SQL Server database, the following steps need to be taken: Confirm the object type (table, view, stored procedure). IF NOT EXISTS can be used to skip creation if the object is empty. If the object has data, use a different name or modify the structure. Use DROP to delete existing objects (use caution, backup recommended). Check for schema changes to make sure there are no references to deleted or renamed objects.

If you accidentally delete a SQL Server database, you can take the following steps to recover: stop database activity; back up log files; check database logs; recovery options: restore from backup; restore from transaction log; use DBCC CHECKDB; use third-party tools. Please back up your database regularly and enable transaction logging to prevent data loss.
