Get the value of the column of which the Serial no is greatest

Question

I have a table(table_name), the columns of which are Sno,count. If wanna get the value of the count column where Sno is, say 1..

SELECT count FROM `table_name` WHERE Sno=1;

gives

count
 2

it works!!!

But what if I wanna get the value of count where Sno is Max?

Sno  count
 1    2
 2    1

Basically I need help creating hybrid of :

SELECT count FROM `table_name` WHERE Sno=1;

&

select MAX(Sno) from table_name;

Answer 1

You can use order by and limit :

SELECT t.*
FROM `table_name` t
ORDER BY Sno DESC
LIMIT 1;
