mysql - How do I order by multiple columns in a SELECT query?

I have a table of records like below

int_record_id     int_category_id  str_name   int_order   bit_active
      1                 1            test1        2           1
      2                 1            test2        1           1
      3                 2            test3        1           1
      1                 3            test4        3           1

i want to select this record in a such a way that it should be sorted in the order of both int_category_id and int_order

so the result should be like below

int_record_id     int_category_id  str_name   int_order   bit_active
      2                 1            test2       1           1
      1                 1            test1       2           1      
      3                 2            test3       1           1     
      4                 3            test4       3           1

Does any one have an idea about its sql query, i have tried a lot i'm not getting the result correct. can any one show me the exact sql query for this.
