Answer 1

To drop a 'customers' database and all associated tables and data, use the SQL command 'DROP DATABASE customers CASCADE;'. This command ensures both the database and its contained tables are dropped, without the need to drop tables individually.

Step-by-step explanation:

To drop a customers database along with all of its tables inside the database, you would typically use SQL commands that can handle both the database and the tables within it. If the tables are managed tables, they are tied closely to the database and dropping the database will also drop the tables. In many database systems, especially the ones that adhere to SQL standards, the command to drop a database and cascade the deletion to all contained objects is:

DROP DATABASE customers CASCADE;

This command ensures that the database called 'customers' and all its associated tables and data are dropped together. The 'CASCADE' keyword is important as it specifies that the drop action should also apply to any dependent objects within the database. It is not necessary to drop all the tables first before dropping the database if you are using the 'CASCADE' option. However, keep in mind that this exact syntax may vary depending on the database system you are using; some systems may have their own specific syntax or commands.
