语法错误 (操作符丢失) 在查询表达式
/// <summary>

/// <returns></returns>
public List<prod_news> ProductFenYe(int begin, int end)
{
try
{
string sqlStr = "select*from(select row_number()over(order by infotime desc)as RowIndex,*from prod_news)as a where RowIndex between "+begin+" and "+end;
OleDbCommand cmd = new OleDbCommand(sqlStr, con);
OleDbParameter par1 = new OleDbParameter("@begin",OleDbType.Integer);
OleDbParameter par2 = new OleDbParameter("@end",OleDbType.Integer);

cmd.Parameters.Add(par1);

while (reader.Read())

prod_news.ok = Convert.ToBoolean(reader["ok"]);
list.Add(prod_news);
}
return list;
}
catch (Exception ec)
{
throw ec;
}
连接的是ACCESS数据库 老提示语法错误 (操作符丢失) 在查询表达式 'row_number()over(order by infotime desc)' 中。 如果是SQL server就没事啊 谁帮解决 谢谢
[解决办法]
把你的sql发到sqlserver专区里面去，可能效果会更好一点。
