Error when importing sql database to phpmyadmin

Hi everyone..

I am attempting to transfer my site to my host and have taken the following steps:

1) I have exported the mysite.sql database and saved as a text file (sql).

2) I have changed the http://localhost/mysite occurrences with http://www.mysite.com, so that hte paths to all documents are correct

3) I also have chanched C:\wamp\www\mysite\blog\wp-content\uploads
with /wp-content/uploads

However, when I go to import the sql file into phpmyadmin I get the following error:

Error
SQL query:

—
— Database: ososantoso
—
— ——————————————————–
—
— Table structure for table wp_commentmeta
—
CREATE TABLE wp_commentmeta (

meta_id BIGINT( 20 ) UNSIGNED NOT NULL AUTO_INCREMENT ,
comment_id BIGINT( 20 ) UNSIGNED NOT NULL DEFAULT ‘0’,
meta_key VARCHAR( 255 ) DEFAULT NULL ,
meta_value LONGTEXT,
PRIMARY KEY ( meta_id ) ,
KEY comment_id ( comment_id ) ,
KEY meta_key ( meta_key )
) ENGINE = MYISAM DEFAULT CHARSET = utf8 AUTO_INCREMENT =1;
