|
Delete a table.
Syntax
<drop table statement> ::=
|
|
|
DROP TABLE [ IF EXISTS ] [ schema-name. ] table-name [ RESTRICT ]
|
Usage
The DROP TABLE statement deletes the table specified by table-name from the database.
Notes
§
|
The current database is implicit if a schema name is not specified.
|
§
|
The IF EXISTS clause can be specified to avoid an exception when attempting to delete a table that does not exist in the database.
|
§
|
Dropping a table automatically deletes all indexes and triggers owned by the table.
|
§
|
RESTRICT, which is implicit and the only supported drop behavior, prevents the table from being deleted if the table is referenced by other tables, views, triggers, procedures or functions.
|
§
|
The DROP TABLE statement requires exclusive access to the table being deleted.
