一段phpmyadamin导出的sql语句，请指教！
create database if not exists primavpdb001 ;
grant all
on primavpdb001.*
to primavpdb001_f@localhost
identified by 'changeme ' ;
flush privileges ;
use primavpdb001;
这段语句，请教各位了！详细点更好，嘿嘿！
------解决方案--------------------
create database if not exists primavpdb001 ;
检查数据库primavpdb001是否存在,不存在则创建
grant all
on primavpdb001.*
to primavpdb001_f@localhost
identified by 'changeme ' ;
flush privileges ;
赋予用户primavpdb001_f在localhost上对primavpdb001数据库中所有数据表的全局权限,密码设置为changeme
use primavpdb001;
打开数据库primavpdb001
