# DROP TABLE
## description
    该语句用于删除 table 。
    语法：
        DROP TABLE [IF EXISTS] [db_name.]table_name [FORCE];
        
    说明：
        1) 执行 DROP TABLE 一段时间内，可以通过 RECOVER 语句恢复被删除的表。详见 RECOVER 语句
        2) 如果执行 DROP TABLE FORCE，则系统不会检查该表是否存在未完成的事务，表将直接被删除并且不能被恢复，一般不建议执行此操作
        
## example
    1. 删除一个 table
        DROP TABLE my_table;
        
    2. 如果存在，删除指定 database 的 table
        DROP TABLE IF EXISTS example_db.my_table;
