I use Dreamweaver also to program my sites, but I think an easier way to achieve this would be this....
Goto your phpMyAdmin - select your appropriate database name, then in the SQL query window paste the contents of your insert.sql file which in this case is the following,
CREATE TABLE comments (
COMMENT_ID int(11) NOT NULL auto_increment,
FIRST_NAME varchar(50) default NULL,
LAST_NAME varchar(50) default NULL,
TELEPHONE varchar(20) default NULL,
EMAIL varchar(50) default NULL,
SUBMIT_DATE datetime default NULL,
COMMENTS longtext,
ANSWERED tinyint(4) default NULL,
PRIMARY KEY (COMMENT_ID),
KEY PRIMARY_KEY (COMMENT_ID)
)
Press GO!
and there you have it! the table "comments" will now be created for you with all the appropriate properties, i.e. varchar, int, longtext, etc...
Thats the way I create my tables....
Surely though you could write your own script for creating tables from a web-form located locally on your workstation.
Hope that helps.
