Transpose a set of values in rows to columns in Access 2010

Question

I have an Access database that looks something like this:

ID     |   TestDate   |  Test1  |  Test2  |  Test 3  |
1      |    Date1     |   10    |    20   |          


        

Answer 1

How about:

TRANSFORM SUM(q.testval) AS sumoftestval
SELECT q.id,
       q.test
FROM   (SELECT t2.id,
               t2.testdate,
               "test1"  AS Test,
               t2.test1 AS TestVal
        FROM   t2
        UNION ALL
        SELECT t2.id,
               t2.testdate,
               "test2"  AS Test,
               t2.test2 AS TestVal
        FROM   t2
        UNION ALL
        SELECT t2.id,
               t2.testdate,
               "test3"  AS Test,
               t2.test3 AS TestVal
        FROM   t2) AS q
GROUP  BY q.id,
          q.test
PIVOT q.testdate; 

Select an ID

TRANSFORM Sum(q.testval) AS sumoftestval
SELECT q.test
FROM (SELECT t2.id,
               t2.testdate,
               "test1"  AS Test,
               t2.test1 AS TestVal
        FROM   t2
        UNION ALL
        SELECT t2.id,
               t2.testdate,
               "test2"  AS Test,
               t2.test2 AS TestVal
        FROM   t2
        UNION ALL
        SELECT t2.id,
               t2.testdate,
               "test3"  AS Test,
               t2.test3 AS TestVal
        FROM   t2)  AS q
WHERE q.id=1
GROUP BY q.test
PIVOT q.testdate;
