在经典asp中执行存储过程并返回值

Question

我需要从asp页调用SQL 2008中具有的存储过程，并将其传递给它两个值，最后返回两个变量的计数。

这是我的存储过程：

        /****** STUDATATAB******/
CREATE PROCEDURE StdntReconcileDups @NewSTDNT int = NULL, @OldSTDNT int = NULL output
AS
--use ZLDP01RD;
--count = 9 rows
Select count (*) from STUDATA.dbo.STUDATATAB
 where STDNT = @NewSTDNT;

-- count = 576 rows
select count(*) from STUDATA.dbo.STUDATATAB
 where STDNT = @OldSTDNT;

-- select duplicate keys with new student# count = 3 rows
select a.STDNT,a.crs,a.CRS_VRSN,a.QSTN,a.SCR
    from STUDATA.dbo.STUDATATABa, STUDATA.dbo.STUDATATABb
        where a.STDNT = @NewSTDNT
        and b.STDNT = @OldSTDNT
        and a.crs = b.crs
        and a.CRS_VRSN=b.CRS_VRSN
        and a.QSTN=b.QSTN
        and a.SCR=b.SCR 

-- select duplicate keys with new student# count = 3 rows
select count (*)
     from STUDATA.dbo.STUDATATABa
     where exists (select 1 from STUDATA.dbo.STUDATATABb
                    where a.STDNT = @NewSTDNT
                      and b.STDNT = @OldSTDNT
                      and a.crs = b.crs
                      and a.CRS_VRSN=b.CRS_VRSN
                      and a.QSTN=b.QSTN
                      and a.SCR=b.SCR );


-- delete duplicate keys with new student# 3 rows deleted
 WITH STUDENT_CTE
  AS
  (select a.*
     from STUDATA.dbo.STUDATATABa
     where exists (select 1 from STUDATA.dbo.STUDATATABb
                    where a.STDNT = @NewSTDNT
                      and b.STDNT = @OldSTDNT
                      and a.crs = b.crs
                      and a.CRS_VRSN=b.CRS_VRSN
                      and a.QSTN=b.QSTN
                      and a.SCR=b.SCR ))
delete from STUDENT_CTE;

--Convert student #10826 history records to student #123196, should update 579 rows
UPDATE STUDATA.dbo.STUDATATAB
 SET STDNT = @NewSTDNT, LSTUPDT_USER_ID_CD = 'DFERN', LSTUPDT_TS = getDate()
 where STDNT = @OldSTDNT;

-- count= 582
select count(*) from STUDATA.dbo.STUDATATAB
 where STDNT = @NewSTDNT;

-- count= 0
Select count(*) from STUDATA.dbo.STUDATATAB
 where STDNT = @OldSTDNT;
go

我想在if参数中插入代码，以便它调用StdntReconcileDups并将其值KeepSTDNT和RemoveSTDNT传递给它

    Dim DBConn  ' Connection object
If Request.Form("Action") = "Go!" then


Endif

Answer 1

这个概念就是执行您的请求...您将返回一个记录集，您将对其进行迭代直到到达eof ...然后将调用下一个记录集以获取下一个结果。

...您是否正在寻找这样的东西？

connectstring = "..."
sql = "StdntReconcileDups '" & NewSTDNT & "','" & OldSTDNT & "'"
set rs = Server.CreateObject("ADODB.RecordSet")

rs.Open sql, connectstring, 3

Answer 2

如果我明白了您的意思...那么请执行以下操作：

 SqlConnection con = new SqlConnection("Data Source=  ; initial catalog= Northwind ; User Id=  ; Password=  '");

        con.open();

创建SqlConnection之后，您将如下创建Storedprocedure：

        CREATE PROCEDURE RegionUpdate (@RegionID INTEGER,@RegionDescription NCHAR(50)) AS
        SET NOCOUNT OFF
        UPDATE Region
        SET RegionDescription = @RegionDescription

创建一个SqlCommand对象，并使用参数作为要执行的存储过程的名称以及将要发送命令以执行的连接对象。

        SqlCommand command = new SqlCommand("RegionUpdate",con);

将命令对象的CommandType属性更改为存储过程 。

    command.CommandType = CommandType.StoredProcedure;

使用Parameters集合和SqlParameter类将参数添加到命令对象。

        command.Parameters.Add(new SqlParameter("@RegionID",SqlDbType.Int,0,"RegionID"));

        command.Parameters.Add(new SqlParameter("@RegionDescription",SqlDbType.NChar,50,"RegionDescription"));

使用参数的Value属性指定参数的值

        command.Parameters[0].Value=4;

        command.Parameters[1].Value="SouthEast";

使用ExecuteNonQuery方法执行存储过程，该方法返回由存储过程影响的行数。

         int i=command.ExecuteNonQuery();

上面的代码是正确的方法...您可以完全替换@KeepSTDNT和@RemoveSTDNT而不是@RegionID和@RegionDescription ...我自己使用过...如果您需要更多帮助...告诉然后
