You can simply do this,

select @count:=@count+1 as SNO, col1, col2 
FROM table, (SELECT @count:=0) r ;

Just like adding RowNumber for each row

select @rownum:=@rownum+1 ‘rank’, 
       p.* 
from player p, (SELECT @rownum:=0) r 
order by score 
desc limit 10;

As per my understanding,you are looking for Row_Number function in this case. If this is correct, please have a look here

e.g. 

Select @count := @count + 1 As SNO, col1, col2
From table ,(SELECT @count:=0) foo

may help

Also you can refer ROW_NUMBER, Partition, and Over in MySQL for more understanding on the same

Combining two queries..

SELECT t1.field1, t1.field2, t2.field1
FROM (query1) as t1, (query2) as t2
WHERE t1.field1= t2.field1
