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

问题

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.

回答1:

select * from your_table order by int_category_id, int_order

回答2:

This query should do:

select * from myTable
order by int_category_id, int_order

You need to decide what you primary sort will be and inside that the secondary (and so on).

So, if you want to sort first by order then by category, you would use:

select * from myTable
order by int_order, int_category_id

See the mySql order by documentation.
