检查从SQL查询返回的多个值

Question

I am trying to run a query on a table which returns two values (call it fstValue and lstValue). I am trying to get my query to return True in cases when the fstValue >=0 AND lstValue <=100, and false in all other cases.

Is there any way to do this in MySQL?

Answer 1

select case when fstValue >=0 AND lstValue <= 100
            then 'true'
            else 'false'
       end as result
from your_table

Answer 2

This one:

set @firstvalue = 98;
set @lastvalue = 100;
select case when (@firstvalue>=0 and @firstvalue<=100) 
and @lastvalue>=0 and @lastvalue<=100 then  'True'
 else  'False' end as '0 to 100';
