Question

I have different MySQL SELECT queries, all with different where statements. These produce totals, unique totals, totals of a certain type.

So for-instance:

Loc    | total | unique | missing

London | 10 | 5 | 2

New York |20 |10 |5

Currently I am running each of these Select queries separately, but I’d rather run them all at once. Is there a way to do this in MySQL?

Something like:

SELECT
    Location
    Count(total)
    SELECT 
        count(unique)
    FROM
        .. my tables..
    WHERE
        .. where clause for unique part ..
    GROUP BY
        unique
FROM
    .. my tables ..
WHERE
    .. where clause for total part ..
GROUP BY
    total

Thank you all. For anyone else trying to get to grips with this, my eventual solution was:

SELECT
   Geo,
   total,
   SUM(unique) as unique
FROM
   (SELECT
      Geo,
      COUNT(total) AS total,
      0 unique,
    FROM
      -- my tables --
    WHERE
      -- where clause for totals --
    GROUP BY 
      Geo)
  UNION
    (SELECT
      Geo,
      0 total,
      COUNT(unique) AS unique,  
     FROM
       -- my tables --
     WHERE 
       -- where clause for unique --
     GROUP BY
       Geo)
) as tmptable
GROUP BY 
   Geo
