MySQL - SELECT * INTO OUTFILE LOCAL ?
MySQL is awesome! I am currently involved in a major server migration and previously, our small database used to be hosted on the same server as the client.
So we used to do this : SELECT * INTO OUTFILE .... LOAD DATA INFILE ....
Now, we moved the database to a different server and SELECT * INTO OUTFILE ....
no longer works, understandable - security reasons I believe.
But, interestingly LOAD DATA INFILE ....
can be changed to LOAD DATA LOCAL INFILE ....
and bam, it works.
I am not complaining nor am I expressing disgust towards MySQL. The alternative to that added 2 lines of extra code and a system call form a .sql script. All I wanted to know is why LOAD DATA LOCAL INFILE
works and why is there no such thing as SELECT INTO OUTFILE LOCAL
?
I did my homework, couldn't find a direct answer to my questions above. I couldn't find a feature request @ MySQL either. If someone can clear that up, that had be awesome!
Is MariaDB capable of handling this problem?
From the manual: The SELECT ... INTO OUTFILE
statement is intended primarily to let you very quickly dump a table to a text file on the server machine. 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."

An example:
mysql -h my.db.com -u usrname--password=pass db_name -e 'SELECT foo FROM bar' > /tmp/myfile.txt
You can achieve what you want with the mysql console with the -s (--silent) option passed in.
It's probably a good idea to also pass in the -r (--raw) option so that special characters don't get escaped. You can use this to pipe queries like you're wanting.
mysql -u username -h hostname -p -s -r -e "select concat('this',' ','works')"
EDIT: Also, if you want to remove the column name from your output, just add another -s (mysql -ss -r etc.)
