Problem with my ALTER TABLE query

[jeddiki]

Can anyone please tell me what is wrong with this query.

This is my code:

$sql = "ALTER TABLE `cb_temp`
   ADD cb_id int(8) auto_increment, primary key (cb_id)
   ADD INDEX id (id),
   ADD INDEX start_date (start_date)";
	
$result = mysql_query($sql)
	or die("could not UPDATE cb_temp". mysql_error());

And I get this error:

could not UPDATE cb_temp:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'primary key (cb_id) ADD INDEX id (id), ADD INDEX start_date (start_date)' at line 2

The columns that I am trying to index id and start_date already exist in the table , but cb_id does not exist, I want to create it and have it filled with consecutive numbers.

Thanks for any help.

Use the following query.
[code=mysql]ALTER TABLE `cb_temp` ADD cb_id int(8) auto_increment, add primary key (cb_id),
ADD INDEX id (id),
ADD INDEX start_date (start_date)[/code]
You were missing ADD before primary key and a comma after (cb_id).
