问题描述

我已经创建了一个WCF服务来连接我的Android应用程序和我在线网站上的SQL数据库。当我尝试使用Android应用程序从我的数据库中获取数据时我没有错误，没有数据我不知道是否有错误在我的代码中。



我尝试过：



编辑网页.config添加：

< webservices>

< protocols>

< add name =HttpSoap12/>

< add name =HttpSoap/>

< add name =HttpGet/>

< add name = HttpPost/>

I have created a WCF services to connect my android app with my SQL database on online site.when I try to get data from my database using android app I got no error and no data I do not know if there is an error in my code.

What I have tried:

editing web.config by adding this :
<webservices>
<protocols>
<add name="HttpSoap12"/>
<add name="HttpSoap"/>
<add name="HttpGet"/>
<add name="HttpPost"/>

推荐答案

我不是100％肯定这个，但你已经将saveStaff定义为查询

I'm not 100% sure about this but you have saveStaff defined as a query

Dim saveStaff As String = "select Spec from Password where Num = @AndroidNum AND Pass = @AndroidPass"

但你用ExecuteNonQu调用它ery

But you call it with ExecuteNonQuery

querySaveStaff.ExecuteNonQuery()

我不确定这个的净效果。它可能会忽略查询，因为它是一个查询，你说的是ExecuteNonQuery，或者它可能正在运行查询而只是忽略而不返回结果。

I'm not sure the net effect of this. It could be ignoring the query because it's a query and you're saying ExecuteNonQuery, or it could be running the query and just ignoring and not returning the results.
