+<p>The DROP TABLE statement removes a table added with the
+<a href="lang_createtable.html">CREATE TABLE</a> statement. The name specified is the
+table name. The dropped table is completely removed from the database
+schema and the disk file. The table can not be recovered.
+All indices and triggers
+associated with the table are also deleted.</p>
+
+<p>The optional IF EXISTS clause suppresses the error that would normally
+result if the table does not exist.</p>
+
+<p>If <a href="foreignkeys.html">foreign key constraints</a> are enabled, a DROP TABLE command performs an
+implicit <a href="lang_delete.html">DELETE FROM</a> command before removing the
+table from the database schema. Any triggers attached to the table are
+dropped from the database schema before the implicit DELETE FROM
+is executed, so this cannot cause any triggers to fire. By contrast, an
+implicit DELETE FROM does cause any configured
+<a href="foreignkeys.html#fk_actions">foreign key actions</a> to take place.
+If the implicit DELETE FROM executed
+as part of a DROP TABLE command violates any immediate foreign key constraints,
+an error is returned and the table is not dropped. If
+the implicit DELETE FROM causes any
+deferred foreign key constraints to be violated, and the violations still
+exist when the transaction is committed, an error is returned at the time
+of commit.
