RE: remote mysqldump to csv (--tab)
Hi You can use on shell, connect at the client mysq -h (host or IP) -p(password) and run the query: SELECT a, b, c INTO OUTFILE '/tmp/result.txt' FIELDS TERMINATED BY ';' OPTIONALLY ENCLOSED BY '' LINES TERMINATED BY '\n' FROM test_table more info see the link http://dev.mysql.com/doc/refman/5.0/en/select-into-statement.html Carlos Caldi Date: Wed, 28 Apr 2010 14:11:14 +0200 From: ma...@psb.vib-ugent.be To: mysql@lists.mysql.com Subject: remote mysqldump to csv (--tab) Hi all, posted this in the backup list, but that one seems to be pretty dead, so i'll try my luck again here: We're currently looking for a way to backup a pretty big mysql table to a csv file. However, we don't want to allow the user ssh or file access to the server, so it'd have to happen remotely. the --tab/-T option allows exporting to csv, but not remotely. So we're looking for a way to have mysqldump store these files remotely, on the client where mysqldump is executed. I've been looking up and down, only to find bad news, so I'm pretty sure it's just not possible. I know there are ways to do this (little script to convert the sql to csv, or pipe it all through sed), but we were just wondering if we're really not overlooking a nifty option in mysqldump :-) Thanks in advance mavoo -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=ce_ca...@hotmail.com _ O Internet Explorer 8 quer te ajudar a navegar seguro.

RE: Trancate table from command line?
John I think you can do this way on shell: mysql -h db_server -u user -pPASSWORD DATABASE -e truncate table table1 Carlos Eduardo Caldi Date: Tue, 16 Mar 2010 14:12:42 -0700 From: joli...@john-oliver.net To: mysql@lists.mysql.com Subject: Trancate table from command line? Is there a way to use mysqladmin (or mysql) to truncate a table as a one-off command from the command line? I have an issue with importing data from one database into another, but the second database might have columns that the first did not. On database 1, I use mysqldump to grab certain tables, and when I try to simply overlay those tables onto the new database, I get an error ERROR 1062 (23000) at line 24: Duplicate entry '378-4' for key 1 So we're thinking we should truncate the table first, but it appears this must be done manually in the mysql shell, which won't work... this operation needs to be scripted, or to be presented as one command line that can be copy-and-pasted. How can I do something like : mysqladmin -h db_server -u user -pPASSWORD DATABASE truncate table table1 ? -- *** * John Oliver http://www.john-oliver.net/ * * * *** -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/mysql?unsub=ce_ca...@hotmail.com _ Não deixe rastros ao navegar na Internet.
