importing data into sql phpadmin

sorry if this is considered a noob question, but i have only just started to learn about sql and php.

I am using phpmyadmin on a remote server to import a sql file which will make some table and import some information.

so far I have the following to make the tables

Code:

---

CREATE TABLE IF NOT EXISTS `est_costcenters` (
  `est_ccorder` int(11) NOT NULL auto_increment,
  `est_cccode` varchar(100) NOT NULL default '',
  `est_ccname` varchar(100) default '',
  `est_ccgl` varchar(100) default '',
  `est_ccsubgroup` varchar(100) default '',
  `est_ccsecret` varchar(100) default '',
  PRIMARY KEY  (`est_ccorder`)
) TYPE=MyISAM;

---

so I have 2 questions.

- can i get it to check if the fields exist and create them if they dont ?
- Can someone show me the code to include information in the fields, the original information is in an access database, but i export to txt csv etc.

Thanks.
