shell脚本操作mysql数据库—创建数据库，在该数据库中创建表(插入，查询，更新，删除操作也可以做)

#!/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
fi

echo "create table ${TABLENAME}"

create_table_sql="create table ${TABLENAME}(
name char(6) NOT NULL,
id int default 0
)ENGINE=MyISAM DEFAULT CHARSET=latin1"
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
 echo "create  table ${DBNAME}.${TABLENAME}  fail ..."
fi
