MySQL Cookbook学习笔记第一章

1，create databse cookbook

2,给数据库cookbook创建一个用户burness，密码为123456

grant  all on cookbook.* to ‘burness’on ‘localhost’ identified by ‘123456’

3,生成一个备份

mysqldump –h localhost –u burness –p cookbook > cookbook.sql

生成的cookbook.sql内容如下：

-- MySQL dump 10.13  Distrib 5.5.25, for Win64 (x86)
--
-- Host: localhost    Database: cookbook
-- ------------------------------------------------------
-- Server version	5.5.25

4,mysql从文件中读取语句

mysql cookbook < filename

eg：mysql cookbook < limbs.sql

limbs.sql内容如下：

drop table if exists limbs;
create table limbs
(
	thing varchar(20),
	legs int,
	arms int
);

insert into limbs (thing,legs, arms) values('human',2,2);
insert into limbs (thing,legs, arms) values('insect',6,0);
insert into limbs (thing,legs, arms) values('squid',0,10);
insert into limbs (thing,legs, arms) values('octopus',0,8);
insert into limbs (thing,legs, arms) values('fish',0,0);
insert into limbs (thing,legs, arms) values('centipede',100,0);
insert into limbs (thing,legs, arms) values('table',4,0);
insert into limbs (thing,legs, arms) values('armchair',4,2);
insert into limbs (thing,legs, arms) values('phonograhp',0,1);
insert into limbs (thing,legs, arms) values('tripod',3,0);
insert into limbs (thing,legs, arms) values('Peg Leg Pete',1,2);
insert into limbs (thing,legs, arms) values('space alien',NULL,NULL);

或者使用source ，eg ： source test.sql

5，mysql还能使用pipe使用程序的查询命令

6，输出重定向：-H -X可以生成HTML，XML内容

mysql  -u burness –p cookbook -e “select * from limbs where legs=0” >1.txt

mysql –H -u burness –p cookbook -e “select * from limbs where legs=0” >1.html

mysql –X -u burness –p cookbook -e “select * from limbs where legs=0” >1.xml

7,当过长的查询输出到屏幕需要一行来垂直地显示输出使用G代替；

select * from limbsG

8，记录交互式的mysql对话

mysql –u burness –p cookbook --tee=tmp.out cookbook

T tmp.out

记录的命令及显示会输出到tmp.out

来停止记录

tmp.out 内容如下:

Welcome to the MySQL monitor.  Commands end with ; or g.

9，在mysql中使用自己定义的变量

@ var_name : value

eg: select @id := cust_id from customers where cust_id=’customer name’;

delete from orders where cust_id=@id;

delete from custers where cust_id=@id;
