MySQL SELECT INTO OUTFILE to a different server?

问题:

I have a shell script on server a. The script spits out a csv file to a local directory. The problem is the database server is on server b. How do I use select * into outfile in a setup like this?

I get

Can't create/write to file '/home/username/test.csv/' (Errcode: 2)

Solved load data infile by using 'LOCAL' keyword. Is there something like that for outfile?

回答1:

select into outfile can only create the file on the server, not the client.

Here's what the manual recommends for your situation:

If you want to create the resulting file on some client host other than the server host, you cannot use SELECT ... INTO OUTFILE. In that case, you should instead use a command such as mysql -e "SELECT ..." > file_name to generate the file on the client host.

Use the command below:

mysql -uusername -ppassword -h DBIP DBNAME -e \
"SELECT * FROM tablename" > /destinationpath/outputfilename.csv
