Union Query?

I have the following query;

SELECT TOP 1 DateTime, TagName, Value, CONVERT(varchar(15), DateTime, 108) AS Time
FROM v_AnalogHistory
WHERE (DateTime >= CAST(CONVERT(VARCHAR(8), GETDATE() - 1, 112) AS DATETIME)) AND (DateTime < CAST(CONVERT(VARCHAR(8), GETDATE(), 112)
AS DATETIME)) AND (TagName = N'LI_759') AND (wwRetrievalMode = N'delta') AND (CONVERT(decimal(38, 3), Value) IS NOT NULL)
ORDER BY CONVERT(decimal(38, 3), Value), CONVERT(varchar(15), DateTime, 108)

which produces the following:






LI_759
-0.001
13:28:20

The second query;

SELECT TOP 1 DateTime, TagName, Value, CONVERT(varchar(15), DateTime, 108) AS Time
FROM v_AnalogHistory
WHERE (DateTime >= CAST(CONVERT(VARCHAR(8), GETDATE() - 1, 112) AS DATETIME)) AND (DateTime < CAST(CONVERT(VARCHAR(8), GETDATE(), 112)
AS DATETIME)) AND (TagName = N'LI_759') AND (wwRetrievalMode = N'delta') AND (CONVERT(decimal(38, 3), Value) IS NOT NULL)
ORDER BY CONVERT(decimal(38, 3), Value) DESC, CONVERT(varchar(15), DateTime, 108) DESC

Produces the following:





LI_759
0.3661
06:09:30


I have tried the previous answers to this post and none of them worked, i get various errors saying sql is unable to parse. what I would like to have is one query that produces the following:

min:



LI_759
-0.001
13:28:20

max:




LI_759
0.3661
06:09:30

Thank You.
