SQL 2005 Group By Query

The below SQL 2005 Group by query works. The additional solution I am looking for is when a Null appears for the ProName. I would like a solution that places the word: "unknown" when the group by results in a Null for ProName? Currently it lists the ProNames and sometimes a Null when the provider is missing from the tables.

SELECT zReports.PhysResp, sum(1) as Volume,
Provider.ProLName + ' ' + Provider.ProFName + ', ' + Provider.Protitle as ProName
FROM Orders
INNER JOIN zReports ON Orders.VisitID = zReports.VisitID
left JOIN Provider ON Provider.ProID = zReports.PhysResp
WHERE
(zReports.TimeIn2 >= '200701010000' AND zReports.TimeIn2 <= '201108302359' and zReports.FacNo = 1 and Orders.OrderType = 'RAD')
Group by ZReports.PhysResp,Provider.ProLName, Provider.ProFName, Provider.Protitle
Order by Provider.ProLName, Provider.ProFName, Provider.Protitle

SELECT 'Number of Titles', Count(*)
FROM titles
GROUP BY
CASE
WHEN price IS NULL THEN 'Unpriced'
WHEN price < 10 THEN 'Bargain'
WHEN price BETWEEN 10 and 20 THEN 'Average'
ELSE 'Gift to impress relatives'
END
GO

It looks like you just need to wrap ProName expression with COALESCE():
COALESCE(Provider.ProLName + ' ' + Provider.ProFName + ', ' + Provider.Protitle, 'Unknown') as ProName

You may also want to account for NULL in any one of the columns also.

COALESCE(Provider.ProLName + COALESCE(' ' + Provider.ProFName, '') + COALESCE(', ' + Provider.Protitle, ''), 'Unknown') as ProName

might need to switch Provider.ProID = zReports.PhysResp around.

SELECT		zReports.PhysResp, 
			sum(1) as Volume,
			CASE WHEN ISNULL(Provider.ProID, '') = '' THEN 'unknown'
				ELSE Provider.ProLName + ' ' + Provider.ProFName + ', ' + Provider.Protitle
				END as ProName
FROM 
			Orders INNER JOIN 
			zReports ON Orders.VisitID = zReports.VisitID left JOIN	
			Provider ON zReports.PhysResp = Provider.ProID
WHERE 
			(zReports.TimeIn2 >= '200701010000' 
			AND zReports.TimeIn2 <= '201108302359' 
			and zReports.FacNo = 1 
			and Orders.OrderType = 'RAD')
Group by 
			ZReports.PhysResp,
			Provider.ProLName, 
			Provider.ProFName, 
			Provider.Protitle 
Order by 
			Provider.ProLName, 
			Provider.ProFName, 
			Provider.Protitle

Try this

SELECT zReports.PhysResp, sum(1) as Volume,
isnull(Provider.ProLName + ' ' + Provider.ProFName + ', ' + Provider.Protitle, 'Unknown') as ProName
FROM Orders 
INNER JOIN zReports ON Orders.VisitID = zReports.VisitID
left JOIN Provider ON Provider.ProID = zReports.PhysResp  
WHERE 
(zReports.TimeIn2 >= '200701010000' AND zReports.TimeIn2 <= '201108302359' and zReports.FacNo = 1 and Orders.OrderType = 'RAD')
Group by ZReports.PhysResp,Provider.ProLName, Provider.ProFName, Provider.Protitle 
Order by Provider.ProLName, Provider.ProFName, Provider.Protitle

all answer were thoughtful. Below is solution:

SELECT zReports.PhysResp, sum(1) as Volume,
IsNull(Provider.ProLName + ' ' + Provider.ProFName + ', ' + Provider.Protitle, 'Unknown') as ProName
FROM Orders
INNER JOIN zReports ON Orders.VisitID = zReports.VisitID
left JOIN Provider ON Provider.ProID = zReports.PhysResp
WHERE
(zReports.TimeIn2 >= '200701010000' AND zReports.TimeIn2 <= '201108302359' and zReports.FacNo = 1 and Orders.OrderType = 'RAD')
Group by ZReports.PhysResp,Provider.ProLName, Provider.ProFName, Provider.Protitle
Order by Provider.ProLName, Provider.ProFName, Provider.Protitle
