导入数据到mysql的一种简单的方法_MySQL

shell脚本

cat ./employee.csv | while read LINE 
do 
 eval $( echo $LINE | awk -F ',' '{print "ds="$1 ";id="$2 ";name="$3}' ) 
 echo ds=$ds id=$id name=$name 
 mysql -uroot -p655453 test --default-character-set=utf8 -e "replace into wechat_employee values('$ds','$id','$name')"
done 

要导入数据到Mysql最重要的一点就是要三码合一，即client和server的编码还有表的编码要一致，server的编码可以在/etc/mysql找一下配置文件修改，客户端的编码在insert之前可以设置一下，可以忽略
