Final answer:
It is true that the SQL command to delete a table's structure can be used with a table that has had its data removed. SQL 'DROP TABLE' command is indifferent to whether or not the table contains data.
Step-by-step explanation:
When considering the correct SQL command to delete a table's structure, it is true that the command can be used whether or not the table has data. The SQL DROP TABLE statement is used to remove a table's structure from the database regardless of its data content. If the data has already been removed using a DELETE statement, it has no impact on the ability to use DROP TABLE.
To address the prompts briefly:
- One table is not more correct than the other in this context; the question pertains to the ability to drop a table, not to the correctness of table design.
- Data can be grouped in many ways depending on the requirement of the database schema, query performance and normalization standards.
- There was no switching between tables in this explanation as the question solely focused on the use of dropping a table
