SQL syntax error near gunzip when restoring a database using .sql.gz file

I am trying to restore a mysql db using a .sql.gz file. I am using mySql console to run a command because file size is too large for phpMyAdmin. Command I am using is

gunzip C:/Vik/Gya/Source/beed_2013-04-06.sql.gz | mysql -u root -p bd

where root is the user id. There is no password for root. bd is the database to which I am trying to import. mysql is running on my local machine (Windows 8). I have a wamp setup.

This is the error I am getting:

ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near
C:/Vikalp/Gyankosh/Source/beedictionary_2013-04-06.sql | mysql -u root
at line 1.

Any help will be greatly appreciated.

Thanks and regards,

If you type gunzip and you get a SQL syntax error that complaints about gunzip, you are already logged into the mysql console. The mysql console is not a general purpose shell!

You are using Windows and I suspect you haven't installed gzip in your computer (it isn't a builtin utility). It's a classical Unix tool but you can find binaries for Windows. Install it and run your original command with a couple of tweaks:

  1. Make sure you're in Windows prompt (C:\>)

  2. Redirect gunzip result to stdout rather than a file:

    gunzip --stdout C:/Vik/Gya/Source/beed_2013-04-06.sql.gz | mysql -u root -p bd

Alternatively, you can run the dump from within MySQL promt (mysql>) if you uncompress it first (you don't need specifically command-line gzip, most GUI archivers such as 7-Zip support this format):

mysql> \. C:/Vikalp/Gyankosh/Source/beedictionary_2013-04-06.sql
