shell脚本操作mysql数据库

#!/bin/bash HOSTNAME=192.168.1.224 #数据库Server信息 PORT=3306 USERNAME=root PASSWORD=123456 DBNAME=test_db_name #要创建的数据库的库名称 TABLENAME=test_table_name #要创建的数据库的表的名称 MYSQL_CMD=mysql -h${HOSTNAME} -P${PORT} -u${USERNA

#!/bin/bash

HOSTNAME="192.168.1.224" #数据库Server信息
PORT="3306"
USERNAME="root"
PASSWORD="123456"

DBNAME="test_db_name" #要创建的数据库的库名称
TABLENAME="test_table_name" #要创建的数据库的表的名称

MYSQL_CMD="mysql -h${HOSTNAME} -P${PORT} -u${USERNAME} -p${PASSWORD}"
echo ${MYSQL_CMD}

echo "create database ${DBNAME}"

create_db_sql="create database IF NOT EXISTS ${DBNAME}"
echo ${create_db_sql} | ${MYSQL_CMD} #创建数据库
if [ $? -ne 0 ] #判断是否创建成功
then
echo "create databases ${DBNAME} failed ..."
exit 1

echo "create table ${TABLENAME}"

create_table_sql="create table ${TABLENAME}(

echo ${create_table_sql} | ${MYSQL_CMD} ${DBNAME} #在给定的DB上，创建表
if [ $? -ne 0 ] #判断是否创建成功
then

或者如下操作

#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}"
