Syntax:
DROP [TEMPORARY] TABLE [IF EXISTS]
    tbl_name [, tbl_name] ...
    [RESTRICT | CASCADE]

DROP TABLE removes one or more tables. You must have the DROP privilege
for each table.

Be careful with this statement! For each table, it removes the table
definition and all table data. If the table is partitioned, the
statement removes the table definition, all its partitions, all data
stored in those partitions, and all partition definitions associated
with the dropped table.

Dropping a table also drops any triggers for the table.

DROP TABLE causes an implicit commit, except when used with the
TEMPORARY keyword. See
https://dev.mysql.com/doc/refman/8.4/en/implicit-commit.html.

*Important*:

When a table is dropped, privileges granted specifically for the table
are not automatically dropped. They must be dropped manually. See [HELP
GRANT].

If any tables named in the argument list do not exist, DROP TABLE
behavior depends on whether the IF EXISTS clause is given:

o Without IF EXISTS, the statement fails with an error indicating which
  nonexisting tables it was unable to drop, and no changes are made.

o With IF EXISTS, no error occurs for nonexisting tables. The statement
  drops all named tables that do exist, and generates a NOTE diagnostic
  for each nonexistent table. These notes can be displayed with SHOW
  WARNINGS. See [HELP SHOW WARNINGS].

IF EXISTS can also be useful for dropping tables in unusual
circumstances under which there is an entry in the data dictionary but
no table managed by the storage engine. (For example, if an abnormal
server exit occurs after removal of the table from the storage engine
but before removal of the data dictionary entry.)

The TEMPORARY keyword has the following effects:

o The statement drops only TEMPORARY tables.

o The statement does not cause an implicit commit.

o No access rights are checked. A TEMPORARY table is visible only with
  the session that created it, so no check is necessary.

Including the TEMPORARY keyword is a good way to prevent accidentally
dropping non-TEMPORARY tables.

The RESTRICT and CASCADE keywords do nothing. They are permitted to
make porting easier from other database systems.

DROP TABLE is not supported with all innodb_force_recovery settings.
