可以用shell腳本操作mysql數據庫，使用mysql的-e參數可以執行各種sql的(創建，刪除，增，刪，改、查)等各種操作 。

mysql  -hhostname -Pport -uusername -ppassword  -e  相關mysql的sql語句，不用在mysql的提示符下運行mysql，即可以在shell中操作mysql的方法。

實例：

#!/bin/bash

HOSTNAME="192.168.111.84"                                           #數據庫信息
PORT="3306"
USERNAME="root"
PASSWORD=""

DBNAME="test_db_test"                                                       #數據庫名稱
TABLENAME="test_table_test"                                            #數據庫中表的名稱

#創建數據庫
create_db_sql="create database IF NOT EXISTS ${DBNAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} -e"${create_db_sql}"

#創建表
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}"

#插入數據
insert_sql="insert into ${TABLENAME} values('billchen',2)"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${insert_sql}"

#查詢
select_sql="select * from ${TABLENAME}"
mysql -h${HOSTNAME}  -P${PORT}  -u${USERNAME} -p${PASSWORD} ${DBNAME} -e"${select_sql}"

#更新數據
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}"

#刪除數據
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}"

mysql -e中 v的作用
