where附近有语法错误
CREATE   PROCEDURE   H_FENYE  
@PAGENUM   INT   OUTPUT   ,--页数
@BG_ID   INT,--信息所属的大类
@CURRPAGE   INT,--当前页的索引
@PAGESIZE   INT--页大小
AS
  DECLARE   @SQLTABLE   AS   NVARCHAR(500)
  SELECT   @PAGENUM=COUNT(*)   FROM   DETAILCLASS   WHERE   BG_ID=@BG_ID
IF(@PAGENUM=1)
  BEGIN
      SET   @SQLTABLE=N 'SELECT   TOP '+STR(@PAGESIZE)+ '*   FROM   DETAILCLASS   WHERE   BG_ID= '+STR(@BG_ID)
  END
ELSE
  BEGIN
      SET   @SQLTABLE=N 'SELECT   TOP '+STR(@PAGESIZE)+ '*   FROM   DETAILCLASS   WHERE   (DET_ID> (SELECT   MAX(DET_ID)   FROM   (SELECT   TOP '   +STR(@PAGESIZE   *   (@CURRPAGE-1))+ 'DET_ID   FROM   DETAILCLASS   WHERE   BG_ID=STR(@BG_ID)   ORDER   BY   DET_ID)AS   T   ))WHERE   @BG_ID= '+STR(@BG_ID)
  END
  EXEC   sp_executesql   @SQLTABLE
GO
大家帮忙看一下!我在查询分析器里执行了一下,能输出参数,可是老报错说where附近有语法错误

------解决方案--------------------
--简单存储过程如下:
----------------------------------------------------
CREATE PROC P_TEST
@Name VARCHAR(20),
@Rowcount INT OUTPUT
AS
BEGIN
SELECT * FROM T_Customer WHERE NAME=@Name
SET @Rowcount=@@ROWCOUNT
END
GO
----------------------------------------------------
--存储过程调用如下:
----------------------------------------------------
DECLARE @i INT
EXEC P_TEST 'A ',@i OUTPUT
SELECT @i
--结果
/*
Name Address Tel
---------- ---------- --------------------
A Address Telphone

(所影响的行数为 1 行)


-----------
1

--DotNet 部分(C#)
--WebConfig 文件:
----------------------------------------------------
......
</system.web>

<!-- 数据库连接字符串
-->
<appSettings>
<add key= "ConnectString " value= "server=(local);User ID=sa;Password=;database=Test " />
</appSettings>

</configuration>
----------------------------------------------------
--C#代码:(用到两个测试控件,DataGrid1(用于显示绑定结果集合),Lable(用于显示存储过程返回单值)
----------------------------------------------------
//添加数据库引用
using System.Data.SqlClient;
......
private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
String DBConnStr;
DataSet MyDataSet=new DataSet();
System.Data.SqlClient.SqlDataAdapter DataAdapter=new System.Data.SqlClient.SqlDataAdapter();
DBConnStr=System.Configuration.ConfigurationSettings.AppSettings[ "ConnectString "];
System.Data.SqlClient.SqlConnection myConnection = new System.Data.SqlClient.SqlConnection(DBConnStr);
if (myConnection.State!=ConnectionState.Open)
{
myConnection.Open();
}
System.Data.SqlClient.SqlCommand myCommand = new System.Data.SqlClient.SqlCommand( "P_Test ",myConnection);
myCommand.CommandType=CommandType.StoredProcedure;
//添加输入查询参数、赋予值
myCommand.Parameters.Add( "@Name ",SqlDbType.VarChar);
