Question

I have two sql queries…

set  @count:=0;
select @count:=@count+1 as SNO, col1, col2 FROM table;

I want to combine above queries into a single query. Any Help?

Answer 1

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;
