备份 mysqldump-A.gz - | gzip > 恢复单表 $ mysql -e "truncate TABLE_NAME $ zgrep ^"INSERT INTO \ ' TABLE_NAME" mysqldump-A.gz | mysql DB_NAME

您可以尝试使用sed，以便只提取所需的表。

假设你的表名为mytable，文件名为mysql。Dump是包含你的巨大转储的文件:

$ sed -n -e '/CREATE TABLE.*`mytable`/,/Table structure for table/p' mysql.dump > mytable.dump

这将复制到文件mytable中。dump位于CREATE TABLE mytable和对应下一个表的下一个CREATE TABLE之间的内容。

然后可以调整文件mytable。其中包含表mytable的结构和数据(一个INSERT列表)。

这也可能有所帮助。

# mysqldump -u root -p database0 > /tmp/database0.sql
# mysql -u root -p -e 'create database database0_bkp'
# mysql -u root -p database0_bkp < /tmp/database0.sql
# mysql -u root -p database0 -e 'insert into database0.table_you_want select * from database0_bkp.table_you_want'

我尝试了一些选择，它们都非常慢。这将在几分钟内将一个360GB的转储拆分到它的表中:

如何将mysqldump的输出分割成更小的文件?

Get a decent text editor like Notepad++ or Vim (if you're already proficient with it). Search for the table name and you should be able to highlight just the CREATE, ALTER, and INSERT commands for that table. It may be easier to navigate with your keyboard rather than a mouse. And I would make sure you're on a machine with plenty or RAM so that it will not have a problem loading the entire file at once. Once you've highlighted and copied the rows you need, it would be a good idea to back up just the copied part into it's own backup file and then import it into MySQL.

一个简单的解决方案是仅为希望单独恢复的表创建一个转储。你可以使用mysqldump命令来这样做，语法如下:

mysqldump -u [user] -p[password] [database] [table] > [output_file_name].sql

然后像往常一样导入它，它只会导入转储的表。
