restoring mysql backup

I'm trying to restore database from backup. I've create new DB:

CREATE DATABASE `my_db` CHARACTER SET utf8

after that I launch big sql, afrter some time there written

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that

line 1

Does anyone know what's up here? I've tried on two backups, and I don't think both are invalid.

Thank you in advance!
