mysql 数据库 切表的脚本

#!/bin/sh



host=$1

port=$2

host=${host:="localhost"}  #host没赋值，那么就赋值为localhost

port=${port:="3306"}

schema=$3

echo $host, $port, $schema



#sleep 15

echo "=====bre2.0 archive tables ...."

date "+%F %T"



dater=`date -d "-1 day" "+%Y%m%d"`

exe_sql="create table Mapping_event_tmp like Mapping_event; rename table Mapping_event to Mapping_event_$dater, Mapping_event_tmp to Mapping_event;"



#如果只传了schema进来， 则只修改该schema下的所有表

if [ "$schema" ] 

then

echo "===="$schema

echo $exe_sql

echo $exe_sql | mysql -h $host -P $port -uusername -ppassword $schema

#如果schema没传则修改该服务器下面的所有表

else 

mysql -h $host -P $port -uusername -ppassword -e "show databases like 'DMP_GDMP%';" -N | while read schema

do 

echo "===="$schema

echo $exe_sql

echo $exe_sql | mysql -h $host -P $port -uusername -ppassword $schema

done

fi

date "+%F %T"

说明 schema是数据库名字
