Question

I have a question:

Does it possible to collect multiple query in one query?

i.e in a Form I have 10 query like this:

1.  SELECT ThisValue FROM thatTable1 WHERE
2.  SELECT ThisValue FROM thatTable2 WHERE
                 .......
10.      SELECT ThisValue FROM thatTable10 WHERE

where should I write i.e this code in Access.It it possible in Access or only I can do that in MS SQL and….

CREATE PROC dbo.proc_app_CollectControlData
AS
    SET NOCOUNT ON

    DECLARE @t TABLE
    (
      CONTROLNAME   nvarchar(74),
      CONTROLVALUE  nvarchar(255)
    )

    -- Now we collect the data for the 10 different controls
    INSERT INTO @t
    (CONTROLNAME, CONTROLVALUE)
    SELECT 'MyFirstControl',
            ThisValue
    FROM dbo.ThatTable
    WHERE Condition1

    ...

    INSERT INTO @t
    (CONTROLNAME, CONTROLVALUE)
    SELECT 'MyTenthControl',
            ThisValue
    FROM dbo.ThatTable
    WHERE Condition10

    -- And now we return all found data to the client
    SELECT * FROM @
    SET NOCOUNT OFF
GO

I think you are looking for the UNION Operator.

SELECT  'MyFirstControl' AS ControlName, ThisValue AS ControlValue
FROM    thatTable1 
WHERE   Condition1 
UNION ALL
SELECT  'MySecondControl' AS ControlName, ThisValue AS ControlValue
FROM    thatTable2
WHERE   Condition2
UNION ALL
SELECT  'MyThirdControl' AS ControlName, ThisValue AS ControlValue
FROM    thatTable3
WHERE   Condition3
