Is it possible to take the table level backup in mysql using any of the script? I am new to MySQL and I am in need of the script which is taking backup of  multiple tables from the multiple databases in single file in MySQL?
To dump only specific tables from a database, name them on the command line following the database name:

mysqldump my_database table1 table3 table5 &gt; dump.sql

To dump only specific tables from multiple database, use mysqldump again, but append to the end of the previously created file:

mysqldump my_database2 table1 table3 table5 &gt;&gt; dump.sql Note the &gt;&gt; sign
