Luca writes "I would like to run the following nested query using MS Access:
Query to be run first (called AGGREGA):
SELECT DatiIndagine.R4A as Risposta
FROM DatiIndagine
WHERE [DatiIndagine.R4A] Is Not Null
UNION ALL SELECT DatiIndagine.R4B as Risposta
FROM DatiIndagine
WHERE [DatiIndagine.R4B] Is Not Null
UNION ALL SELECT DatiIndagine.R4C as Risposta
FROM DatiIndagine
WHERE [DatiIndagine.R4C] Is Not Null
Query to be run once the AGGREGA has been run:
SELECT Aggrega.Risposta, Count(Aggrega.Risposta) AS Totale_Risposte
FROM Aggrega
GROUP BY Aggrega.Risposta
ORDER BY Count(Aggrega.Risposta) DESC
Can you suggest how I can code this in order to create a recordset? Can I do it with a single SQL statement? If yes, how?
Thank you,
Luca" |
