SingleStore DB

DROP TABLE

Drop the specified table.

Syntax
DROP [TEMPORARY] TABLE [IF EXISTS] <table_name> [FORCE];
Remarks
  • <table_name> is the name of a table in a SingleStore database.

  • This command can be run on the master aggregator node, or a child aggregator node (see Node Requirements for SingleStore DB Commands ).

  • If there is a view which depends on a table, the table cannot be dropped. See CREATE VIEW for more information.

  • By default, the DROP TABLE command waits for the running queries to finish before dropping the table. To override this behavior and kill any running queries, use the FORCE option.

  • Table memory can be freed when the DROP TABLE command is run.

    For information on when/how much table memory is freed when this command is run, see Managing Memory.

  • DROP TEMPORARY TABLE does not perform a COMMIT when run; issue a COMMIT prior to DROP TEMPORARY TABLE if there are uncommited statements.

  • Because temporary tables only exist for the duration of a client session, no access privileges are required to run DROP TEMPORARY TABLE.

  • Unlike when running the DROP TABLE command, running the DROP TEMPORARY TABLE command does not commit implicitly.

  • DROP TEMPORARY TABLE cannot drop global temporary tables.

  • A temporary or global temporary table can be dropped using DROP TABLE without specifying the TEMPORARY option.

Example
DROP TABLE IF EXISTS mytbl;
DROP TABLE IF EXISTS tab1 FORCE;
