Lindorm:DROP TABLE

Last Updated:Apr 08, 2024

You can use the DROP TABLE syntax to delete a specified table from the current database.

Applicable engines

The DROP TABLE syntax is applicable to LindormTable and LindormTSDB.

Syntax

drop_table_statement ::=  DROP TABLE [ IF EXISTS ] table_identifier

Usage notes

Before you execute the DROP TABLE statement to delete a specified table from the current database, take note of the following items:

  • If the LindormTable version of your instance is in a range from 2.2.16 to 2.4.1, you must manually execute an OFFLINE TABLE statement to set the state of the table to offline before you execute the DROP TABLE statement to delete the table. For more information about the OFFLINE TABLE syntax, see OFFLINE TABLE.

  • After a table is deleted by using the DROP TABLE syntax, the storage used to store the table is not immediately released. You can configure a TTL for the database to completely delete the data of a deleted table. For more information about how to configure a TTL for a database, see ALTER DATABASE.

Examples

Delete a table named sensor.

DROP TABLE IF EXISTS sensor;
