sql query help - trying to get rid of temp tables - sql

Question

I have the following tables -
Resource
--------------------
Id, ProjectId, Hours, ApproverId
Project
--------------------
Id, Name
The input is ApproverId. I need to retrieve all the rows that have matching ApproverId (simple enough). And for every resource that I get back, I also need to get their hours (same table) whose approverId is not the one that is passed in (business requirement, to be grayed out in the UI). What I'm doing right now is - get all resources based on ApproverId, stored them in a temp table, then do a distinct on Resource.Id, store it in a different temp table, and then for every Resource.Id, get the rows where the ApproverId is not the one that is passed. Can I combine it all in a single query instead of using temp tables?
Thanks!
Edit: I'm using SQL Server 2008 R2.
Edit 2: Here's my stored procedure. I have changed the logic slightly after reading the comments. Can we get rid of all temp tables and make it faster -
ALTER PROCEDURE GetResourceDataByApprover
#ApproverId UNIQUEIDENTIFIER
AS
CREATE TABLE #Table1
(
Id SMALLINT PRIMARY KEY
IDENTITY(1, 1) ,
ResourceId UNIQUEIDENTIFIER
)
CREATE TABLE #Table2
(
ResourceId UNIQUEIDENTIFIER ,
ProjectId UNIQUEIDENTIFIER ,
ProjectName NVARCHAR(1024)
)
INSERT INTO #Table1
SELECT DISTINCT
ResourceId
FROM dbo.Resource T
WHERE T.ApproverId = #ApproverId
DECLARE #i INT
DECLARE #numrows INT
DECLARE #resourceId UNIQUEIDENTIFIER
SET #i = 1
SET #numrows = ( SELECT COUNT(*)
FROM #Table1
)
IF #numrows > 0
WHILE ( #i <= ( SELECT MAX(Id)
FROM #Table1
) )
BEGIN
SET #resourceId = ( SELECT ResourceId
FROM #Table1
WHERE Id = #i
)
INSERT INTO #Table2
SELECT
T.ResourceId ,
T.ProjectId ,
P.Name AS ProjectName
FROM dbo.[Resource] T
INNER JOIN dbo.Project P ON T.ProjectId = P.ProjectId
WHERE T.ResourceId = #resourceId
SET #i = #i + 1
END
SELECT *
FROM #Table1
SELECT *
FROM #Table2
DROP TABLE #Table1
DROP TABLE #Table2

Answer 1

This query should return two rows for every resource, one for the specified approver and one for all other approvers.
SELECT
Id,
CASE
WHEN ApproverId=#approverId THEN 'SpecifiedApprover'
ELSE 'OtherApprover'
END AS Approver,
SUM(Hours) AS Hours
FROM Resource
GROUP BY
Id,
CASE
WHEN ApproverId=#approverId THEN 'SpecifiedApprover'
ELSE 'OtherApprover'
END

Answer 2

Do you want to know how concrete Approver wastes his time?
SELECT p.Id, p.Name, SUM(r.Hours) as TotalHours
FROM Resource r
LEFT JOIN Project p
ON r.ProjectId = p.Id
WHERE ApproverId = %ConcreteApproverId%
GROUP BY p.Id, p.Name
HAVING SUM(r.Hours) > 0
This query will produce this table example:
+-----+----------+-------+
| Id | Project | Hours |
+-----+----------+-------+
| 203 | ProjectA | 25 |
| 202 | ProjectB | 34 |
| 200 | ProjectC | 46 |
+-----+----------+-------+
