c:\users\jack> mysqldump-uroot-pmysql Sva_rec date_rec_drv> e:\date_rec_drv.sql
3. Export a database structure
c:\users\jack> mysqldump-uroot-pmysql-d sva_rec > E:\sva_rec.sql
4. Export a table with only a table structure
Mysqldump-u User name-p password-d database name Table name > exported file name
c:\users\jack> mysqldump-uroot-pmysql-d Sva_rec date_rec_drv> e:\date_rec_drv.sql
5. Import the database

mysql> use MySQL;
mysql> UPDATE user SET Password = Password (' newpass ') WHERE user = ' root ';
