# DROP DATABASE
## description
    该语句用于删除数据库（database）
    语法：
        DROP DATABASE [IF EXISTS] db_name [FORCE];

    说明：
        1) 执行 DROP DATABASE 一段时间内，可以通过 RECOVER 语句恢复被删除的数据库。详见 RECOVER 语句
        2) 如果执行 DROP DATABASE FORCE，则系统不会检查该数据库是否存在未完成的事务，数据库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. 删除数据库 db_test
        DROP DATABASE db_test;
## keyword
    DROP,DATABASE
