I have two tables:

TB1: Has the population of cities. Multiple cities in a state.
    int population
    varchar city
    varchar state (FK)

TB2
   varchar state (PK)
   int status

Now I need to run queries that do the following:

1) Set the column TB2.status = 1 if the population of a state > 1 million
2) Delete records from TB2 where population of state < 100,000

Can you point me in the right direction.

Thanks.
