When you need to create a new database table, all you should be thinking about are the table columns, right? Well, with the new scbTable class added in version 1.2, you can.
Creating a table is as easy as:
new scbTable('my_table', __FILE__, " id bigint(20) unsigned NOT NULL default 0, foobar varchar(100) NOT NULL, PRIMARY KEY (id), ");
The class takes care of creating or updating the table structure, as necessary.
Also, you can access it with
$wpdb->my_table, just like you would any other WordPress table.
