Describe DROP TABLE command of SQL along with both the options - CASCADE and RESTRICT.
DROP TABLE command - This command drops the specified table. Dropping a table also drops indexes and grants related with it. Objects built on dropped tables are marked invalid and cease to work.
CASCADE and RESTRICT options - The DROP TABLE with RESTRICT option destroy the table unless a few view or integrity constraint refer to the given table; if so, the command fails. Other than along with the CASCADE option, any referencing views or integrity constraints are (recursively) dropped as well.
