问题 I want to back up only the Views with mysqldump. Is this possible? If so, how? 回答1: NOTE: This answer from Ken moved from suggested edit to own answer. here's a full command line example using a variant of the above mysql -u username INFORMATION_SCHEMA --skip-column-names --batch -e "select table_name from tables where table_type = 'VIEW' and table_schema = 'database'" | xargs mysqldump -u username database > views.sql This extracts all of the view names via a query to the INFORMATION_SCHEMA

由 馋奶兔 提交于 2019-12-17 22:04:36
问题 I'm confused how to import a SQL dump file. I can't seem to import the database without creating the database first in MySQL.

问题 I am looking for the syntax for dumping all data in my mysql database. I don't want any table information. 回答1: mysqldump --no-create-info ...

问题 I need to do a mysqldump of a database on a remote server, but the server does not have mysqldump installed. I would like to use the mysqldump on my machine to connect to the remote database and do the dump on my machine. I have tried to create an ssh tunnel and then do the dump, but this does not seem to work. I tried: ssh -f -L3310:remote.server:3306 user@remote.server -N The tunnel is created with success. If I do telnet localhost 3310 I get some blurb which shows the correct server mysql

How to deal with enormous line lengths created by mysqldump

问题 I'm using mysqldump in a cron job to backup a database with over 2 million rows. It creates a text file which can be used to restore the datalog from the command line. I thought it would be useful to edit the dump before a restore as a quick way of changing values and table or column names - at least until I learn more and become confident about doing it with ALTER and UPDATE. Editing large text files does not bother me, but I was surprised to find that in a 250 megabyte dump of my database,

How can I slow down a MySQL dump as to not affect current load on the server?

问题 While doing a MySQL dump is easy enough, I have a live dedicated MySQL server that I am wanting to setup replication on. To do this, I need dumps of the databases to import to my replication slave. The issue comes when I do the dumps, MySQL goes full force at it and ties up resources to the sites that connecting to it. I am wondering if there is a way to limit the dump queries to a low priority state to which preference is given to live connections? The idea being that the load from external

Where I can find a list of “mysqldump” exit codes?

问题 I know that exit code = 0 means No error . I got exit code = 2 . What does it means ? Where I can see the complete list of mysqldump exit codes ? 回答1: Taken from client/mysqldump.c in MySQL 5.1.59: #define EX_USAGE 1 #define EX_MYSQLERR 2 #define EX_CONSCHECK 3 #define EX_EOM 4 #define EX_EOF 5 /* ferror for output file was got */ #define EX_ILLEGAL_TABLE 6 Skimming through the source, EX_MYSQLERR seems to be used mostly for errors from the server, but also in case malloc fails. CONSCHECK
