Question

create procedure dat(
@d datetime,
@e datetime,
@LEFT datetime,
@day int)
as
begin 
set @d=(SELECT (DATEADD(WEEK, DATEDIFF(WEEK, 0,DATEADD(DAY,6-DATEPART(DAY,GETDATE()),GETDATE())), 0) +28)) 
set @e=( select SYSDATETIME ()) 
SET @LEFT=@d-@e; 
set @day=(select DAY(@LEFT)) 
select region,cast((((TOTAL*55)/100)-(CAST((SUM(EMI)/100) AS DECIMAL(2,2))+CAST((SUM([REPO ARREAR])/100) AS DECIMAL(2,2))))/@day as decimal(3,3)) DRR from DCC GROUP BY TOTAL ,CIRCLE ,REGION  ORDER BY CIRCLE,REGION 
end

这是我的程序。我正在SQL Server 2008中编写此过程。

try
{
 Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
 con = DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=Repo;user=sa;password=sam123;");
String SQL=("{call [DCR].[dbo].[dat]()}");  
CallableStatement cs = con.prepareCall(SQL);
rss=cs.executeQuery(); 
while(rss.next())
{
 float day=rss.getFloat(2);
}
}
catch(Exception e){
 }

这是我的jsp代码。我没有得到ResultSet中的值。请帮帮我。

你不能从JSP调用一个过程，这不是这样做的方法。它需要用Java完成，如下所示

 CallableStatement sqlCallStmt = null; 
 sqlCallStmt = connection.prepareCall("{call Time(?,?)}")
 sqlCallStmt.registerOutParameter(1, java.sql.Types.VARCHAR);
 sqlCallStmt.setString(2,test);
 sqlCallStmt.execute();

如何在jsp中调用过程
