I can't drop the table. I have to add as many columns as posible and when I exceed the limit I have to create another table.
I've tried normalizing but then the join's cost is too big. I always need to use all columns, so getting a all information into a single row it's the most efficient solution.

Also, can you drop and recreate the table every so often? That would
certainly help.
