问题描述
我有我的mysql数据库的mysqldump备份，该数据库由我们的所有表组成，大约440兆.我想从mysqldump恢复表之一的内容.这可能吗?从理论上讲，我可以剪掉重建所需表的部分，但我什至不知道如何有效地编辑该大小的文本文档.
I have a mysqldump backup of my mysql database consisting of all of our tables which is about 440 megs. I want to restore the contents of just one of the tables form the mysqldump. Is this possible? Theoretically, I could just cut out the section that rebuilds the table I want but I don't even know how to effectively edit a text document that size.
推荐答案
您可以尝试使用sed来仅提取所需的表.
You can try to use sed in order to extract only the table you want.
让我们说表的名称是mytable，文件mysql.dump是包含巨大转储的文件:
Let say the name of your table is mytable and the file mysql.dump is the file containing your huge dump:
$ sed -n -e '/CREATE TABLE.*`mytable`/,/CREATE TABLE/p' mysql.dump > mytable.dump
这将在文件mytable.dump中复制位于CREATE TABLE mytable和对应于下一个表的下一个CREATE TABLE之间的内容.
This will copy in the file mytable.dump what is located between CREATE TABLE mytable and the next CREATE TABLE corresponding to the next table.
然后您可以调整文件mytable.dump，该文件包含表mytable的结构和数据(INSERT的列表).
You can then adjust the file mytable.dump which contains the structure of the table mytable, and the data (a list of INSERT).
