mysql我的散亂筆記，慎重參考

mysql學習筆記
 select substring(now(),1,10);

mysql登錄  大寫字母P是端口
C:\Program Files\MySQL\MySQL Server 5.6\bin>
 mysql -h 127.0.0.1 -P -u root -p

設置root帳戶的密碼
mysql> set password for 'xp'@'127.0.0.1'=password('xp132018');

修改密碼：
C:\Program Files\MySQL\MySQL Server 5.6\bin>mysqladmin -u root -ppasswd password abc

mysql數據庫遠程:
grant all PRIVILEGES on *.* to 'root'@'192.168.0.%' identified by '3613571';
flush privileges;
(第一個*是數據庫，第二個* 表示數據庫中的表， win表明帳戶，%表明ip地址，  win456 表明帳戶密碼)

show databases;
use TD_OA;
show tables;
select * from user;
select * into outfile 'd:/test.xls' from  表名



 create table aaa (ID INT(11),NAME varchar(255));

insert into student values('102','李四','八年級');

drop table student;     刪除表


數據庫的備份

C:\Program Files\MySQL\MySQL Server 5.5\bin>mysqldump.exe -u root -p mysql student > mysql_bak.sql  (備份指定的mysql數據庫的student表)

mysqldump.exe -u root -p mysql > mysql_bak.sql  （備份數據庫mysql中的所有表）


數據庫的還原
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysql -u root -p mysql < mysql_bak.sql


grant replication slave  on *.* to 'xp'@'192.168.1.9' identified by 'xp456' with grant option;
