I have an Access DB I have coded in VBA which my team use to log all of our requests. I want to create a query which will pull multiple counts from a single table with different criteria. An example of the table follows:

    Table TLogging
    logTypeId - Int [ this is 0 - 5 ] 
    isResolved - Boolean [ this is stored as -1 for true, 0 for false ]

I want to create a query which will output something like the following:

    Resolved, LogType1, LogType2
    True      101       39
    False     49        104
    All       150       144

So I want:

    Count of LogType1 where isResolved = True
    Count of LogType1 where isResolved = False
    Count of LogType1 where isResolved = True OR isResolved = False

And the same for LogType2.

I have already searched SO and other forums, but found no solutions. Also, CASE WHEN does not work in Access VBA.

Thanks in advance for your help!

你可以从这样的事情开始：

SELECT logTypeId, Count(logTypeId) AS nbTotal, -1 * Sum(isResolved) AS nbTrue, Count(logTypeId) + Sum(isResolved) As nbFalse
FROM TLogging
GROUP BY logTypeId;

它给出了与您想要的结果大致相同的结果，但已转置。

编辑：或者这个，它很丑，但我认为它给出了你想要的结果

SELECT 'True' As Resolved, t0.nb As LogType0, t1.nb As LogType1, t2.nb As LogType2, t3.nb As LogType3, t4.nb As LogType4, t5.nb As LogType5
FROM (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 0)  AS t0
    , (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 1)  AS t1
    , (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 2)  AS t2
    , (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 3)  AS t3
    , (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 4)  AS t4
    , (Select -1 * Sum(isResolved) As nb From TLogging Where logTypeId = 5)  AS t5
Union All
SELECT 'False' As Resolved, t0.nb As LogType0, t1.nb As LogType1, t2.nb As LogType2, t3.nb As LogType3, t4.nb As LogType4, t5.nb As LogType5
FROM (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 0)  AS t0
    , (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 1)  AS t1
    , (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 2)  AS t2
    , (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 3)  AS t3
    , (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 4)  AS t4
    , (Select Count(*) + Sum(isResolved) As nb From TLogging Where logTypeId = 5)  AS t5
Union All
SELECT 'All' As Resolved, t0.nb As LogType0, t1.nb As LogType1, t2.nb As LogType2, t3.nb As LogType3, t4.nb As LogType4, t5.nb As LogType5
FROM (Select Count(*) As nb From TLogging Where logTypeId = 0)  AS t0
    , (Select Count(*) As nb From TLogging Where logTypeId = 1)  AS t1
    , (Select Count(*) As nb From TLogging Where logTypeId = 2)  AS t2
    , (Select Count(*) As nb From TLogging Where logTypeId = 3)  AS t3
    , (Select Count(*) As nb From TLogging Where logTypeId = 4)  AS t4
    , (Select Count(*) As nb From TLogging Where logTypeId = 5)  AS t5
