Question

I want to make a query that will give the result on order by using two columns.
I made query like this.

select 
    el.*,
    lb.LabName,lb.LabType,
    lb.LabDescription
from encounterlab el
INNER JOIN
    labs lb
    ON 
    lb.LabType=el.LabType
where 
    PatientAcctNo=4 ORDER BY el.DataOfService,lb.LabName DESC

It gives the results.But My aim is IF in the DataOfService contain the same date I want to make the Order depending upon the LabName and this should be ASC

Answer 1

you can optionally specify the order for each single field in the order by statement

ORDER BY field1 DESC, field2 ASC
