Question

I have a table, TableA, that looks like this:

ColA    ColB
0        20
1        10
0        5
1        15

I want to sort the rows so that all the records where ColA = 0 are listed first, and then these records are sorted by ColB ascendingly. After all the rows with ColA = 0 are listed, I then want to list all the rows with ColA = 1 but these rows sorted by ColB descendingly.

The results should look like this:

ColA    ColB
0        5
0        20
1        15
1        10

Is this possible? Thanks for your help.

order by t.ColA
   ,case when t.ColA = 0 then t.ColB end asc
   ,case when t.ColA = 1 then t.ColB end desc
