mysqldump对于DB进行逻辑备份的时候,是否会备份视图呢?

需求描述:
今天在mysql备份的书的内容,提到了mysqldump在备份数据库的时候,不会备份视图
所以,就做了个实验测试下,发现,是能够备份视图的,在此记录下.
环境描述:
Mysql版本:5.5.57-log
操作过程:
1.对某个DB进行备份,库中包含视图v_test01
[mysql@redhat6 mysql_backup]$ mysqldump -uroot -p --single-transaction --master-data --databases top_server > TopServerDB.sql Enter password:
2.查看备份出来的SQL文件是否包含view相关信息
[mysql@redhat6 mysql_backup]$ grep "v_test01" TopServerDB.sql -- Temporary table structure for view `v_test01` DROP TABLE IF EXISTS `v_test01`; /*!50001 DROP VIEW IF EXISTS `v_test01`*/; /*!50001 CREATE TABLE `v_test01` ( -- Final view structure for view `v_test01` /*!50001 DROP TABLE IF EXISTS `v_test01`*/; /*!50001 DROP VIEW IF EXISTS `v_test01`*/; /*!50001 VIEW `v_test01` AS select `goods_share_order`.`id` AS `id`,`goods_share_order`.`share_num` AS `share_num`,`goods_share_order`.`contack_user` AS `contack_user`,`goods_share_order`.`contact_tel` AS `contact_tel`,`goods_share_order`.`share_date` AS `share_date`,`goods_share_order`.`share_deptid` AS `share_deptid`,`goods_share_order`.`goods_desc` AS `goods_desc`,`goods_share_order`.`goods_memo` AS `goods_memo`,`goods_share_order`.`creat_time` AS `creat_time`,`goods_share_order`.`update_time` AS `update_time`,`goods_share_order`.`operate_user` AS `operate_user`,`goods_share_order`.`refuse_num` AS `refuse_num`,`goods_share_order`.`total_num` AS `total_num`,`goods_share_order`.`dept_id` AS `dept_id`,`goods_share_order`.`share_status` AS `share_status`,`goods_share_order`.`user_id` AS `user_id`,`goods_share_order`.`remark` AS `remark` from `goods_share_order` */;
备注:说明备份出来的包括视图的信息,与书上说的内容不符合,可能是版本的区别.
3.将DB进行还原,在navicat中查看是否有视图
备注:视图已经被还原回来了.说明这个mysql版本是能够备份视图的.
