Thanks Don. I had a nested query as shown below and a WHERE clause in it wasn't able to determine alias v1. Here is the code which isn't working:

Select 
    teamid,
    teamname
FROM
    team as t1
INNER JOIN (
    SELECT 
        venue_id, 
        venue_scores, 
        venue_name 
    FROM venue 
    WHERE venue_scores = (
        SELECT 
            MAX(venue_scores) 
        FROM venue as v2 
        WHERE v2.venue_id = v1.venue_id      /* this where clause wasn't working */
    ) as v1    /* v1 alias already present here */
);

So, I just added the alias v1 again inside the JOIN. Which made it work.

Select 
    teamid,
    teamname
FROM
    team as t1
INNER JOIN (
    SELECT 
        venue_id, 
        venue_scores, 
        venue_name 
    FROM venue as v1              /* added alias v1 here again */
    WHERE venue_scores = (
        SELECT 
            MAX(venue_scores) 
        FROM venue as v2 
        WHERE v2.venue_id = v1.venue_id   /* Now this works!! */
    ) as v1     /* v1 alias already present here */
);

Hope this will be helpful for someone.
