Upgrade Problem: Run db_upgrade0.2-0.3.sql

[kance]

I'm trying to upgrade and in step 3 it says to "3. Run db_upgrade0.2-0.3.sql (example) using phpMyAdmin or a similar tool" The hosting company I use provides phpMyAdmin 2.5.2-pl1. Where do I go on phpMyAdmin to do step 3 to upgrade?

Thanks in advance.
