DROP TABLE

Function

DROP TABLE deletes a table.

Precautions

DROP TABLE forcibly deletes the specified table and the indexes depending on the table. After the table is deleted, the functions and stored procedures that need to use this table cannot be executed. Deleting a partitioned table also deletes all partitions in the table.

The owner of a table, the owner of the schema of the table, users granted with the DROP permission on the table, or users granted with the DROP ANY TABLE permission can delete the specified table. The system administrator has the permission to delete the specified table by default.

Syntax

DROP TABLE [ IF EXISTS ] 
    { [schema.]table_name } [, ...] [ CASCADE | RESTRICT ];

Parameter Description

IF EXISTS
Reports a notice instead of an error if the specified table does not exist.
schema
Specifies the schema name.
table_name
Specifies the table name.
CASCADE | RESTRICT
- CASCADE: automatically deletes the objects (such as views) that depend on the table.
- RESTRICT: refuses to delete the table if any objects depend on it. This is the default action.
