asp.net 网站代码本地和服务器是一样的，但是测试的结果却不同！！！
网站代码是在本地改好测试没问题后再上传到服务器上的，本地能取到数据表中对应参数所有的记录，但是远程浏览器测试时只能取到一条，且每个参数下取到的都是相同的！前台代码

--------------------编程问答-------------------- 你用sqlserver跟踪器跟踪一sql语句，然后在sql里查下看看到底这条语句查询出什么结果 --------------------编程问答-------------------- 用SqlServer profiler 抓sql语句 看看就知道了 --------------------编程问答--------------------
这是数据表中的记录，http://www.400visa.com/visalist_q_beijing.html 测试 ，只能得到一条啊--------------------编程问答--------------------
图传错了！--------------------编程问答--------------------
不会用！
--------------------编程问答--------------------
百度一下了.有图说明
--------------------编程问答--------------------
嗯
--------------------编程问答--------------------
先不说别的，只读一条记录，貌似C#里面有个方法是只读出一条记录的。貌似ExecuteScalar()这个函数就是只读一样或者一列的，你看看你是不是用到了这个方法。。。
--------------------编程问答--------------------
把sql语句单显示出来，放到数据库上去测，看到底有多少条记录，然后就知道大概是代码问题，还是sql或库的问题了
--------------------编程问答--------------------
测试了，无论本地还是服务器数据库，符合条件的记录都能读出来，不止一条
--------------------编程问答--------------------
应该是代码方面的问题的可能性打了。在程序中多设几个数据显示的点，看出来的结果和期望的是否一致，是能发现问题所在的
--------------------编程问答--------------------
把执行的sql 放到查询分析器执行下
--------------------编程问答--------------------
我找到问题的原因，程序没有执行if (type == "q")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='1'", id);
typeid = 2;
}
if (type == "j")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='2'", id);
typeid = 3;
}
这段代码， 直接进入后台执行region = Td_RegionManager.GetTd_RegionByRegionEname(name);，那我现在要怎么才能让程序先执行if (type == "q")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='1'", id);
typeid = 2;
}
if (type == "j")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='2'", id);
typeid = 3;
}，呢
using System.Web.Security;--------------------编程问答-------------------- 我现在只想通过 region = Td_RegionManager.GetTd_RegionByRegionEname(name);
using System.Web.UI;
using System.Web.UI.HtmlControls;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Xml.Linq;
using visa.BLL;
using visa.Models;
public partial class visalist : System.Web.UI.Page
{
protected Td_Region region;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string get = Request.QueryString["id"].ToString();
string[] array = get.Split('_');
string name = array[2];
region = Td_RegionManager.GetTd_RegionByRegionEname(name);
int id = region.RegionId;
string type = array[1];
string sql = "";
int typeid = 0;
if (type == "q")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='1'", id);
typeid = 2;
}
if (type == "j")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='2'", id);
typeid = 3;
}
region = Td_RegionManager.GetTd_RegionByRegionId(id);
Repeaterlx.DataSource = Td_VisaManager.SelectAllTd_VisasBySql(sql);
Repeaterlx.DataBind();
Td_Kword kword = Td_KwordManager.GetTd_KwordByKwordId(typeid);
//国家region.FK_Country.CouName;
//大区 region.RegionName;
LtlKword.Text = "<title>" + kword.KwordTitle + "</title><meta name=\"keywords\" content=\"" + kword.KwordKey + "\" /><meta name=\"description\" content=\"" + kword.KwordDescribe + "\"/>";
}
}
}
int id = region.RegionId; 这个方法得到td_region数据表记录的id，但是现在在执行这个方法的过程中后台已经把程序走了一遍，导致只能读取表中的第一条记录，根本没有执行
if (type == "q")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='1'", id);
typeid = 2;
}
if (type == "j")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='2'", id);
typeid = 3;
}
所以得不到表td_visa中匹配的记录，那我怎么才能只得到td_region数据表记录的id，同时不阅遍数据表，程序继续运行根据id通过以下方法
f (type == "q")在阅历数据表啊 --------------------编程问答--------------------
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='1'", id);
typeid = 2;
}
if (type == "j")
{
sql = string.Format("select * from td_visa where visaregionid={0} and visatype='2'", id);
typeid = 3;
}
region = Td_RegionManager.GetTd_RegionByRegionId(id);
Repeaterlx.DataSource = Td_VisaManager.SelectAllTd_VisasBySql(sql);
Repeaterlx.DataBind();
--------------------编程问答--------------------
一般引起数据问题就是环境变化引起的，你只看到代码有没有问题,就没考虑过你服务器环境和你本地有什么不同吗？比如数据库
--------------------编程问答--------------------
我发现问题了，是代码在执行过程中调用方法执行顺序 有问题，但是不知道怎么改
--------------------编程问答--------------------
那就按照正确的逻辑思维改呗
补充：.NET技术 , C#
