shell脚本操作mysql数据库，使用mysql的-e参数可以执行各种sql的(创建，删除，增，删，改、查)等各种操作

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