If you ve got many database it import and the dumps is big  I often work with multigigabyte Gzipped dumps    There here a way to do it inside mysql     mkdir databases   cd databases   scp user orgin   sql gz      Here you would just use putty to copy into this dir    mkfifo src   mysql -u root -p Enter password  Welcome to the MySQL monitor   Commands end with   or  g  Your MySQL connection id is 1 Server version  5 5 41-0 Copyright  c  2000  2014  Oracle and or its affiliates  All rights reserved  Oracle is a registered trademark of Oracle Corporation and or its affiliates  Other names may be trademarks of their respective owners Type  help   or   h  for help  Type   c  to clear the current input statement   mysql gt  create database db1  mysql gt       zcat  db1 sql gz  gt  src  amp    mysql gt  source src     mysql gt  create database db2  mysql gt       zcat  db2 sql gz  gt  src  amp    mysql gt  source src   The only advantage this has over  zcat db1 sql gz   mysql -u root -p    is that you can easily do multiple without enter the password lots of times

If the mysql dump was a  gz file  you need to gunzip to uncompress the file by typing   gunzip mysqldump sql gz  This will uncompress the  gz file and will just store mysqldump sql in the same location   Type the following command to import sql data file     mysql -u username -p -h localhost test-database  lt  mysqldump sql password

The file is a gzipped  compressed  SQL file  almost certainly a plain text file with  sql as its extension  The first thing you need to do is copy the file to your database server via scp   I think PuTTY s is pscp exe    Copy it to the server via pscp C   gt  pscp exe numbers sql gz user serverhostname  home user   Then SSH into your server and uncompress the file with gunzip  user serverhostname   gunzip numbers sql gz user serverhostname   ls   numbers sql   Finally  import it into your MySQL database using the  lt  input redirection operator   user serverhostname   mysql -u mysqluser -p  lt  numbers sql   If the numbers sql file doesn t create a database but expects one to be present already  you will need to include the database in the command as well   user serverhostname   mysql -u mysqluser -p databasename  lt  numbers sql   If you have the ability to connect directly to your MySQL server from outside  then you could use a local MySQL client instead of having to copy and SSH   In that case  you would just need a utility that can decompress  gz files on Windows   I believe 7zip does so  or you can obtain the gzip gunzip binaries for Windows

For an oneliner  on linux or cygwin   you need to do public key authentication on the host  otherwise ssh will be asking for password     gunzip -c numbers sql gz   ssh user host mysql --user user name --password your password db name   Or do port forwarding and connect to the remote mysql using a  local  connection   ssh -L some port host local mysql port user host  then do the mysql connection on your local machine to localhost some port   The port forwarding will work from putty too  with the similar -L option or you can configure it from the settings panel  somewhere down on the tree
