For SQL server, the following will return the first row from giving table.

declare @rowNumber int = 1;
    select TOP(@rowNumber) * from [dbo].[someTable];
EXCEPT
    select TOP(@rowNumber - 1) * from [dbo].[someTable];

You can loop through the values with something like this:

WHILE @constVar > 0
BEGIN
    declare @rowNumber int = @consVar;
       select TOP(@rowNumber) * from [dbo].[someTable];
    EXCEPT
       select TOP(@rowNumber - 1) * from [dbo].[someTable];  

       SET @constVar = @constVar - 1;    
END;
