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}"
