使用mysql命令导出表数据（不是mysqldump）

Question

I want to do an export of a table and we do not have mysqldump installed.

I thought I can do this:

root:~> mysql news media > news.media.7.26.2016.sql

where news is the database name and media is the table name

it doesn't seem to work correctly.

Answer 1

Your command tries to mimic mysqldump but mysql does not have a table parameter. You could run it like this:

mysql -D news -e "SELECT * FROM media" > news.media.7.26.2016.txt

That will work but you won't get nice SQL statements in the output, just tabular data export.

I mean that you may (or may not) run into problems when importing the data back. There's a chance to use

mysql -D news -e "LOAD DATA INFILE 'news.media.7.26.2016.txt' INTO TABLE media"

but I do not have much experience with that. First of your concerns is secure-file-priv setting that has been made strict starting in MySQL 5.7.6. Second, I would be a tad bit nervous about preserving data types.
