我正在使用SQL Server 2008，我正在尝试只返回一个结果集。
当前存储过程：
ALTER PROCEDURE dbo.Usp_rptofficertotalef2 (@sFromClause NVARCHAR (1000),
@sWhereClause NVARCHAR (3000),
@sOfficerID VARCHAR(8000))
AS
BEGIN
DECLARE @sSQL NVARCHAR (4000)
SET @sSQL = '

as [Officer Name]
, count (gc_type.code) as [Total GCs]
from officer
, gc_type
, gc
, gc_officer_dispatch
where (gc.gc_final_type_id = gc_type.gc_type_id)
and (officer.officer_id = gc_officer_dispatch.officer_id)
and (gc.gc_id = gc_officer_dispatch.gc_id)
and (gc.gc_id in (select gc.gc_id ' + @sFromClause + ' '
+ @sWhereClause + '))'
IF ( @sOfficerID <> '~' )
BEGIN
SET @sSQL = @sSQL + ' and officer.officer_id in ( '

END
SET @sSQL = @sSQL + '

END
BEGIN
DECLARE @vSQL VARCHAR (8000),
@vTemp VARCHAR(8000)
CREATE TABLE #tempgctime

SET @vTemp = ' insert into #tempGCtime

EXEC (@vTemp)
SET @vSQL =

DROP TABLE #tempgctime
END
这是使用：
执行的exec usp_rptOfficerTotalEF 'from GC
, GC_TYPE
, GC_DISPATCH_LOCATION
, ADDRESS
, CALL_STATUS
, OFFICER'
, 'where GC.GC_ID = GC_DISPATCH_LOCATION.GC_ID
and ADDRESS.ADDRESS_ID = GC_DISPATCH_LOCATION.ADDRESS_ID
and GC.GC_FINAL_TYPE_ID = GC_TYPE.GC_TYPE_ID
and GC.CALL_STATUS_ID = CALL_STATUS.CALL_STATUS_ID
and GC.PRIMARY_OFFICER_ID *= OFFICER.OFFICER_ID
and GC.INITIAL_CALL_TIME >= ''12/1/2013''
and GC.INITIAL_CALL_TIME <= ''2/25/2014 11:59:59 PM'''
, '~'
我将清理为exec传递的变量，这不是问题。 问题是这会返回
Officer name | Total GCs
------------------------------------------
Officer 1 | 2
Officer 2 | 1
Officer name | Total GC Time (Minutes)
------------------------------------------
Officer 1 | 27
Officer 2 | 0
我想要实现的是
Officer name | Total GCs | Total GC Time (Minutes)
------------------------------------------
Officer 1 | 2 | 27
Officer 2 | 1 | 0
为了尝试解决这个问题，我使用了这个：
create table #temp
([Officer Name] VARCHAR(100),
[Officer ID] INT,
[Total GC] INT,
[Total GC Time (Minutes)] INT,
[Total Side Job (Minutes)] INT,
[Total Arrests] INT);
GO
SELECT gc.gc_id
INTO #temp2
FROM GC
, GC_TYPE
, GC_DISPATCH_LOCATION
, ADDRESS
, CALL_STATUS
, OFFICER
WHERE GC.GC_ID = GC_DISPATCH_LOCATION.GC_ID
and ADDRESS.ADDRESS_ID = GC_DISPATCH_LOCATION.ADDRESS_ID
and GC.GC_FINAL_TYPE_ID = GC_TYPE.GC_TYPE_ID
and GC.CALL_STATUS_ID = CALL_STATUS.CALL_STATUS_ID
and GC.PRIMARY_OFFICER_ID *= OFFICER.OFFICER_ID
and GC.INITIAL_CALL_TIME >= '12/1/2013'
and GC.INITIAL_CALL_TIME <= '2/25/2014 11:59:59 PM'
GO
INSERT INTO #TEMP
select
o.last_name + ', ' + IsNull (o.first_name, '') as [Officer Name],
o.OFFICER_ID as [Officer ID],
count (gt.code) as [Total GCs],

from

INNER JOIN GC_TYPE gt ON gc.gc_type_id = gt.gc_type_id
LEFT JOIN GC_PARTY_INVOLVED gpi ON gc.gc_id = gpi.gc_id
where
gc.gc_id in (SELECT gc_id FROM #temp2)
group by
o.officer_id,
o.last_name,
o.first_name
order by

o.first_name
GO
Create Table #tempGCtime(gc_id numeric(9))
GO
insert into #tempGCtime
select gc.gc_id

and INITIAL_CALL_TIME <= '2/25/2014 11:59:59')
GO
DECLARE @gcid int
DECLARE TableCursor CURSOR FOR
SELECT gc_id FROM #tempGCtime
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @gcid
WHILE @@FETCH_STATUS = 0
BEGIN
UPDATE #TEMP SET [Total GC Time (Minutes)] =
(SELECT
isNull(Sum(DateDiff(mi, GC_OFFICER_DISPATCH.ARRIVAL_TIME,
GC_OFFICER_DISPATCH.CLEAR_TIME)),0) as [Total GC Time (Minutes)]
FROM GC_CATEGORY
INNER JOIN GC_TYPE
ON GC_CATEGORY.GC_CATEGORY_ID = GC_TYPE.GC_CATEGORY_ID
INNER JOIN GC
ON GC_TYPE.GC_TYPE_ID = GC.GC_FINAL_TYPE_ID
INNER JOIN GC_OFFICER_DISPATCH
ON GC.GC_ID = GC_OFFICER_DISPATCH.GC_ID
INNER JOIN OFFICER
ON GC_OFFICER_DISPATCH.OFFICER_ID = OFFICER.OFFICER_ID
WHERE (gc.gc_id in (select isNull(gc_id,-1)
from #tempGCtime))
and #temp.[Officer ID] = (SELECT OFFICER_ID
FROM GC_OFFICER_DISPATCH
WHERE GC_ID in (SELECT gc_id
FROM #temp2
WHERE gc_id = @gcid)))
FETCH NEXT FROM TableCursor INTO @gcid
END
CLOSE TableCursor
DEALLOCATE TableCursor
GO
输出格式正确，但数据不正确。
Officer name | Total GCs | Total GC Time (Minutes)
------------------------------------------
Officer 1 | 2 | 0
Officer 2 | 1 | 14
有没有更简单的方法来实现这一点，而不是通过游标使用更新？ （是的，我知道，人们对游标不屑一顾，但这个查询永远不会有太多数据，因此速度慢不是问题）
