Using the Min() function Source provided

[Jeff Strenge]

I need to find the shortest distance that is calculated on lines 2 and 3 of the SQL statement below. When I use SQL statement below it gives me all four records, with the calculated value as expect.

Select Building.Building_Name,
sqrt(pow((342506-Building_Location.Lat_North),2)
+pow((cos(342506)*(874104-Building_Location.Long_West)),2))
from Building inner join Building_Location on
Building.BuildingID=Building_Location.BuildingID
where Building_Location.CellID=31
group by Building_name

if I use the min() function I STILL get all four RECORDS all I want is the record with the Smallest calculated value.
Does anyone know what is wrong with the SQL statement below.

Select Building.Building_Name, the
MIN(sqrt(pow((342506-Building_Location.Lat_North),2)
+pow((cos(342506)*(874104-Building_Location.Long_West)),2)))
from Building inner join Building_Location on
Building.BuildingID=Building_Location.BuildingID
where Building_Location.CellID=31
group by Building_name

Thanks
for your helpful Solutions
