Export MySQL Database using Command line Interface

First check if your command line recognizes mysql command. If not go to command and type in

set path=c:\wamp\bin\mysql\mysql5.1.17\bin

Then use this command to export your database

mysqldump -u YourUserName -p YourDatabaseName > backup_database_file_name.sql

This exports the database to the path you are currently in, while executing this command

More commands fro export/Backup database or databases.

# Backup a single database
# NOTE: you can also use the shortcuts -u and -p to specify username and password
mysqldump –user=… –password=… your_database_name > your_database_name.sql

# Backup multiple databases:
mysqldump –user=… –password=… –databases db1 db2 > backup.sql

# or all the databases in one shot:
mysqldump –user=… –password=… –all-databases > backup.sql

# Optionally, it’s easy to compress the backup, for example with gzip:
mysqldump –user=… –password=… your_database_name \
| gzip > your_database_name.sql

# And, if your database also has other objects (apart from tables) such as functions,
# views, and stored procedures, you can back them up too with –routines:

mysqldump –user=… –password=… –routines \
your_database_name > your_database_name.sql

# It may also be useful to include a timestamp in the target file name, so to know
# right away when a backup was taken:

mysqldump –user=… –password=… \
your_database_name > “your_database_name-$(date +%Y-%m-%d-%H.%M.%S).sql”

# If you are backing up data with the purpose of restoring it to an instance you want
# to use as replication slave, then the option –master-data is handy as it adds to
# the dump the information needed to configure the connection with the
# replication master:

mysqldump –user=… –password=… –all-databases –master-data > backup.sql
