Question

以下是我的查询

select    
@monNameStr as [MName],             
IsNull(count(c.AssignmentID),0),                
IsNull(sum(s.ACV),0),               
IsNull(sum(s.GrossReturn),0),               
IsNull(sum(s.NetReturn),0),             
IsNull(avg(a.Total),0)          
FROM

dbo.Assignment_ClaimInfo c,             
dbo.Assignment_SettlementInfo s,                
dbo.Assignment_AdvCharges a         

Where
c.Assignmentid=s.Assignmentid and               
s.Assignmentid=a.Assignmentid and               
a.Assignmentid in                   

(select AssignmentID from dbo.Assignment_ClaimInfo                  
where (upper(InsuranceComp)=upper(@CompName) or upper(@CompName)='ALL COMPANIES') 
and (DateName(month,DATEADD(month, 0, DOFileClosed))+' '
+cast(year(DATEADD(month, 0, DOFileClosed)) as varchar)=@monNameStr))
Group By c.InsuranceComp
Order By c.InsuranceComp

where @monNameStr is calculated date field like 'October 2009'

我需要知道的是什么。受此选择查询影响的记录。

我不需要用COUNT（）函数将这个查询到另一个查询。

非常感谢您的宝贵帮助。

Answer 1

将@@ ROWCOUNT捕获到变量中，因为每次选择它时都会更改值：

DECLARE @Rows   int

---your query here

SELECT @Rows=@@ROWCOUNT

然后您可以根据需要使用@Rows

Answer 2

查询运行后，您可以检查@@ ROWCOUNT的值。有关详细信息，请参阅http://technet.microsoft.com/en-us/library/ms187316.aspx。

Answer 3

select @@ROWCOUNT

（例如Counting the number of deleted rows in a SQL Server stored procedure）

Answer 4

You can just use `@@ROWCOUNT` to get the records affected/returned

DECLARE @rowsreturned INT
SET @rowsreturned = @@ROWCOUNT

没有。在SQL Server 2005中运行select查询后受影响的行数
