DROP TABLE

On this page

Before you can remove a table, you must remove all its dependent objects (indexes, materialized views, etc.).

Syntax

DROP TABLE [ IF EXISTS ] [schema_name.]table_name [ CASCADE ];

Parameter	Description
schema	Specify the name of a schema to remove the table in that schema. You can use SHOW SCHEMAS to get a list of all available schemas. If you don’t specify a schema, the specified source in the default schema public will be removed.
table	The name of the table to remove. You can use SHOW TABLES to get a list of all available tables.
CASCADE option	If this option is specified, all objects (such as materialized views) that depend on the table, and in turn all objects that depend on those objects will be dropped.
