Which command is used to delete a database in Databricks?

The command used to delete a database in Databricks is "DROP DATABASE." This command is part of SQL syntax used in relational databases and data warehouse management. When you issue the DROP DATABASE command, it removes the specified database and all of its associated objects, such as tables and views, if the "CASCADE" option is included. This ensures that both the database and its contents are entirely removed from the system.

Using "DROP DATABASE" aligns with standard SQL practices across various database platforms, making it a familiar command for users with experience in SQL. In contrast, commands like "REMOVE DATABASE," "DELETE DATABASE," and "ERASE DATABASE" do not conform to standard SQL syntax or Databricks' specific commands and, therefore, are not recognized by the system for deleting databases.
