#!/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 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 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}"
