DROP TABLE keyword
DROP TABLE
permanently deletes a table and its contents. DROP ALL TABLES
permanently deletes all the tables and their contents.
Backup your database to avoid unintended data loss.
Syntax
IF EXISTS
An optional IF EXISTS
clause may be added directly after the DROP TABLE
keywords to indicate that the selected table should be dropped if it exists.
Description
This command irremediably deletes the data in the target table. Unless the table was created in a different volume than the standard, see CREATE TABLE IN VOLUME, in which case the table is only logically removed and data remains intact in its volume. In doubt, make sure you have created backups of your data.
Disk space is reclaimed asynchronously after the table is dropped. Ongoing table reads might delay space reclamation.
Example
DROP TABLE ratings;
DROP ALL TABLES;
