shell脚本操作mysql数据库

使用 mysql -e 参数可以执行各种 sql 的各种操作语句。不用在mysql的提示符下运行mysql,即可以在shell中操作mysql的方法。

  格式:mysql  -hhostname -Pport -uusername -ppassword  -e "" 

  

#!/bin/bash  

HOSTNAME="192.168.111.84"                                           #数据库信息
PORT="3306"
USERNAME="root"
PASSWORD=""

DBNAME="test_db_test"                                                       #数据库名称
TABLENAME="test_table_test"                                            #数据库中表的名称

#也可以写 HOSTNAME="localhost",端口号 PORT可以不设定

 #创建数据库
create_db_sql="create database IF NOT EXISTS ${DBNAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} -e "${create_db_sql}"

注意:-p${PASSWORD}中间不能有空格

#创建表
create_table_sql="create table IF NOT EXISTS ${TABLENAME} (  name varchar(20), id int(11) default 0 )"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD}  -D ${DBNAME} -e "${create_db_sql}"

#插入数据
insert_sql="insert into ${TABLENAME} values('billchen',2)"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e  "${insert_sql}"

#查询
select_sql="select * from ${TABLENAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${select_sql}"

#更新数据
update_sql="update ${TABLENAME} set id=3"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e "${update_sql}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e  "${select_sql}"

#删除数据
delete_sql="delete from ${TABLENAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e  "${delete_sql}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e  "${select_sql}"
