DROP TABLE
Function
DROP TABLE deletes a specified table.
Precautions
DROP TABLE forcibly deletes a specified table. After a table is deleted, any indexes that exist for the table will be deleted; any functions or stored procedures that use this table cannot be run. Deleting a partitioned table also deletes all partitions in the table.
Syntax
DROP TABLE [ IF EXISTS ] { [schema.]table_name } [, ...] [ CASCADE | RESTRICT ];
Parameter Description
- IF EXISTS
Sends a notice instead of an error if the specified table does not exist.
- schema
Specifies the schema name.
- table_name
Specifies the name of the table.
- CASCADE | RESTRICT
- CASCADE: automatically deletes objects (such as views) that depend on the table to be deleted.
- RESTRICT (default): refuses to delete the table if any objects depend on it. This is the default.
Example
Delete the warehouse_t1 table.
