I\'m using SQL Server and I\'m trying to find results but I would like to get the results in the same order as I had input the conditions.
My code:

This is not an answer, just some test-code to check John Cappelletti's approach.
DECLARE @tbl TABLE(ID INT IDENTITY,SomeGuid UNIQUEIDENTIFIER);
--Create more than 6 mio rows with an running number and a changing Guid
WITH tally AS (SELECT ROW_NUMBER()OVER(ORDER BY (SELECT NULL)) AS Nmbr
FROM master..spt_values v1
CROSS JOIN master..spt_values v2)
INSERT INTO @tbl
SELECT NEWID() from tally;
SELECT COUNT(*) FROM @tbl; --6.325.225 on my machine
--Create an XML with nothing more than a list of GUIDs in the order of the table's ID
DECLARE @xml XML=
(SELECT SomeGuid FRom @tbl ORDER BY ID FOR XML PATH(''),ROOT('root'),TYPE);
--Create one invalid entry
UPDATE @tbl SET SomeGuid = NEWID() WHERE ID=10000;
--Read all GUIDs out of the XML and number them
DECLARE @tbl2 TABLE(Position INT,TheGuid UNIQUEIDENTIFIER);
INSERT INTO @tbl2(Position,TheGuid)
SELECT ROW_NUMBER() OVER(ORDER BY (SELECT NULL))
,g.value(N'text()[1]',N'uniqueidentifier')
FROM @xml.nodes(N'/root/SomeGuid') AS A(g);
--then JOIN them via "Position" and check,
--if there are rows, where not the same values get into the same row.
SELECT *
FROM @tbl t
INNER JOIN @tbl2 t2 ON t2.Position=t.ID
WHERE t.SomeGuid<>t2.TheGuid;
At least in this simple case I always get exactly only the one record back which was invalidated...
