There are times when you only want to take partial dump of a mysql table. You can use mysqldump command with one extra option “–where”. You will have to provide your where clause (partial dump condition) in the “–” where option.
Below is the command to take a partial dump of a table.
mysqldump -u [username] -p [databasename] [mytablename] --where " mycolumn = 'somevalue' " > filename.sql
1. MySQL dump in XML format.
2. MySQL general query logs.
To take dump in XML format you have to provide an extra option in default mysqldump command. This can be useful in cases where you want to migrate your MySQL database to some other database.
You can use below command to take MySQL Database dump in XML format.
mysqldump --xml -u[username] -p[password] [db_name] > filename.xml
mysqldump -X -u[username] -p[password] [db_name] > filename.xml
For example if you have a database test_database with an username as root and password as mypassword the command to take dump will be,
mysqldump --xml -u root -p mypassword test_database > filename.xml
