mysqldump导出部分数据的方法： 加入--where参数

mysqldump -u用户名 -p密码 数据库名 表名 --where="筛选条件" > 导出文件路径

 

mysqldump -uroot -p --set-gtid-purged=OFF mysql user --where="user='zejin'"  > zejin.sql;

加入--set-gtid-purged=OFF是因为我在配置中开启GTID

若不加入会报如下的警告：

Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed suppressed parts of the database. If you don't want to restore GTIDs, pass --set-gtid-purged=OFF. To make a complete dump, pass --all-databases --triggers --routines --events.

 

导出后结果如下：
