Re: Exporting to CSV. Error Code: 2013. Lost connection to MySQL server during query
Hi Monty, First of all, thanks so much for responding to my question! I am using MySQLworkbench 5.2.37CE. I'm pretty sure the issue has to do with something on the administrator side of things. We managed to get it so that I can click the icon to export the file, but he's still working on getting it so that we can write an sql query to do this. So for all practical purposes on my end, the question is being resolved. But I don't understand how clicking the icon after running a select query works for exporting, but the command to outfile in a sql query would not work.

2012/07/26 06:52 +0530, Dhaval Jaiswal SELECT * FROM test INTO OUTFILE '/home/test.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '' LINES TERMINATED BY '\n' as above give your join condition before INTO OUTFILE. Right: MySQL server writes into some directory where it is, not where MySQL client is. If less than a full path name is given, almost certainly the server will attempt to write into a directory to which it has no permission, and almost certainly also not into one that you want it to write into. If server and client run on separate machines with separate disks, there is no means through OUTFILE of there setting the output where the client is, only through client s standard output, where you get no choice of field separator, line separator, or field-quote character (there is none), although you can keep or skip the column names (-N for skipping them), and suppress the one-character escape character (-r), same as FIELDS ESCAPED BY ''. There is no means of skipping NULL or \N for nulls, which is not CSV format. And if your MySQL is under Windows, be sure to read all instructions about entering full pathnames. It is best to avoid the backslash (\), because that is a C-escape introduced (along with much other C-stuff) into SQL s original PL1. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql
