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

You need -c option (output to stdout)

gunzip -c xxx.sql.gz |mysql -u root -p

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

While Kisoft´s answer is the correct one, I just wanted to point out that you don´t need the -c, it works just fine as it is. this command will unzip the database dump and import it into the database at the same time.

gunzip < output.sql.gz | mysql -u <username> -p<password> <database>
