Answer 1

Please try this, it is helpful to you

It is possible by using a stored procedure and function, which I created it's have a extra column which you could be create in your table FLAG name and column all field value should be 0 Then it works

create Procedure proc_randomprimarykeynumber
as
    declare @Primarykeyid int  

    select top 1  
        @Primarykeyid = u.ID 
    from 
        StateAbbreviation u  
    left join  
        StateAbbreviation v on u.ID = v.ID + 1 
    where 
        v.flag = 1 

    if(@Primarykeyid is null )
    begin
        UPDATE StateAbbreviation 
        SET flag = 0  

        UPDATE StateAbbreviation 
        SET flag = 1 
        WHERE ID IN (SELECT TOP 1 ID 
                     FROM dbo.StateAbbreviation)
    END
    ELSE
    BEGIN
        UPDATE StateAbbreviation 
        SET flag = 0 

        UPDATE StateAbbreviation 
        SET flag = 1 
        WHERE ID IN (@Primarykeyid)
    END 

    SET @Primarykeyid = 1 

    SELECT TOP 1 
        ID, Abbreviation 
    FROM
        StateAbbreviation 
    WHERE
        flag = 1

It is made in stored procedure run this and get serial wise primary key

exec proc_randomprimarykeynumber

Thanks and regard

Answer 2

You need both a variable and a time seed to not get the same sequence(s) each time you open Access and run the query - and to use Access SQL in Access:

SELECT TOP 1 Abbreviation
FROM STATEABBREVIATION
ORDER BY Rnd(-Timer()*[ID]);

where ID is the primary key of the table.

Answer 3

Ypercude provided a link that led me to the right answer below:

SELECT TOP 1 ABBREVIATION
FROM STATEABBREVIATION 
ORDER BY RND(ID);

Note that for RND(), I believe that it has to be an integer value/variable.

Answer 4

Try this:

SELECT TOP 1 *
FROM tbl_name
ORDER BY NEWID()

Of course this may have performance considerations for large tables.
