Question

When the correct SQL command is used to delete a table's structure, what happens to the data in the table?

1) If the deleted table was a parent table, the data is added to the appropriate rows of the child table.
2) If the deleted table was a child table, the data is added to the appropriate rows of the parent table.
3) The data in the table is also deleted.
4) Nothing because there was no data in the table since only an empty table can be deleted.
5) A and B

Answer 1

The correct SQL command for deleting a table's structure, known as the DROP TABLE operation, results in the deletion of both the table's structure and its associated data. It does not transfer data to any parent or child table.

Step-by-step explanation:

When the correct SQL command is used to delete a table's structure, the data in the table is also deleted. This is known as a DROP TABLE operation, which removes both the table structure and its associated data from the database. In the case of deleting a parent or child table in a relational database, the deletion operation does not result in transferring the data to the other table. Instead, all the data in the table specified in the DROP TABLE command is permanently removed.

It's important to differentiate between the DROP TABLE command and the DELETE command. The DROP TABLE command removes the entire table structure along with its data, while the DELETE command is used to remove specific rows from a table, leaving the table structure in place. Furthermore, when the DROP TABLE command is executed, it does not check for empty tables; it will remove a table regardless of whether it has data or not.
