How can I reset an autoincrement database table to rebuild it's numbers?

Here's the scenario: I have a database table with 118 rows. Due to testing the first 82 rows are gone. So I want to reset the autoincrement field for all rows - 82 so row 83 is numbered 1, 84 = 2, 85 = 3 and so on.

I tried UPDATE autoincrement SET autoincrement = (autoincrement - 82) but that doesn't seem to work. I'm guessing maybe because the autoincrement field is the primary key for the database.

I know I could change these all manually... but can't it be done with one simple query?

Thanks
