DROP TABLESPACE

Name

DROP TABLESPACE -- remove a tablespace

Synopsis

DROP TABLESPACE [ IF EXISTS ] name

描述

DROP TABLESPACE removes a tablespace from the system.

A tablespace can only be dropped by its owner or a superuser. The tablespace must be empty of all database objects before it can be dropped. It is possible that objects in other databases might still reside in the tablespace even if no objects in the current database are using the tablespace. Also, if the tablespace is listed in the temp_tablespaces setting of any active session, the DROP might fail due to temporary files residing in the tablespace.

参数

注解

DROP TABLESPACE cannot be executed inside a transaction block.

例子
