我的页面一运行就提示‘@pagesize‘ 附近有语法错误。但是我在数据库里直接查询，把那些参数替换掉就OK，这句SQL我不知道到底错在哪里
- C# code
-
string sql = "select top @pagesize from member where userid not in(select top(@pagesize*(@pagecount-1)) userid from member order by userid) order by userid";
-----------------------------------------这里是使用这句SQL的方法--------------------------------
- C# code
-
/// <summary> /// 分页获取用户 /// </summary> /// <param name="pageSize">每页用户数</param> /// <param name="pageCount">第几页</param> /// <returns></returns> public DataTable GetUser(int pageSize, int pageCount) { string sql = "select top @pagesize from member where userid not in(select top(@pagesize*(@pagecount-1)) userid from member order by userid) order by userid"; SqlParameter[] parameters = new SqlParameter[2]; parameters[0] = new SqlParameter("@pagesize", SqlDbType.Int); parameters[0].Value = pageSize; parameters[1] = new SqlParameter("@pagecount", SqlDbType.Int); parameters[1].Value = pageCount; return new SqlDbHelper(connectionString).ExecuteDataTable(sql, CommandType.Text, parameters); //todo:必须将上面的代码修改正确！ /* string sql = "select top 20 * from member"; return new SqlDbHelper(connectionString).ExecuteDataTable(sql); */ }
-------------------------------这里是ExecuteDataTable方法---------------------------------------------- ExecuteDataTable是周金桥老师写的那个SqlDbHelper数据库操作的通用类里的 下面是SqlDbHelper中ExecuteDataTable的代码
- C# code
-
/// <summary> /// 执行一个查询,并返回查询结果 /// </summary> /// <param name="sql">要执行的SQL语句</param> /// <param name="commandType">要执行的查询语句的类型，如存储过程或者SQL文本命令</param> /// <param name="parameters">Transact-SQL 语句或存储过程的参数数组</param> /// <returns></returns> public DataTable ExecuteDataTable(string sql, CommandType commandType, SqlParameter[] parameters) { DataTable data = new DataTable();//实例化DataTable，用于装载查询结果集 using (SqlConnection connection = new SqlConnection(connectionString)) { using (SqlCommand command = new SqlCommand(sql, connection)) { command.CommandType = commandType;//设置command的CommandType为指定的CommandType //如果同时传入了参数，则添加这些参数 if (parameters != null) { foreach (SqlParameter parameter in parameters) { command.Parameters.Add(parameter); } } //通过包含查询SQL的SqlCommand实例来实例化SqlDataAdapter SqlDataAdapter adapter = new SqlDataAdapter(command); adapter.Fill(data);//填充DataTable } } return data; }

改成这样试试 top (@pagesize)

改成这样试试 top (@pagesize)
string strSql = @"select m.* from MemberInfo m left join Dictionary d on m.RepresentativeName=d.Name where 1=1 and m.DeleteFlag=0 "; List<DbParameter> list = new List<DbParameter>(); if (!string.IsNullOrEmpty(name)) { strSql += " and m.MemberName like @name"; list.Add(new SqlParameter("name", "%"+name+"%")); } if (!string.IsNullOrEmpty(meetingSesName)) { strSql += " and [email protected]"; list.Add(new SqlParameter("@meetingSesName", meetingSesName)); } strSql += " order by d.Sort asc,convert(int,m.Sequence),convert(int,m.SerialNo)"; return base.ExecuteDataset(strSql, CommandType.Text,list.ToArray()).Tables[0].DefaultView;
DAL中的一句sql总是提示'@pagesize'附近有语法错误。
