我正在将 wcf rest 服务消耗到 angular js 应用程序中。我正在尝试通过 Wcf Rest Service 显示来自 sql 数据库的数据。我正在使用 Union 函数来加入多表记录。当我在输入字段中输入帐户并单击提交按钮时，我想在网页中显示帐户信息，但问题是它不是所需的数据..
这里是类。
public class AccountTransaction
{
public int? Account_Number { get; set; }
public decimal? Deposit { get; set; }
public decimal? Withdrawal { get; set; }
public decimal? Account_Balance { get; set; }
public string Account_Type { get; set; }
public string Account_Holder_Tittle { get; set; }
public string Account_Holder_FirstName { get; set; }
public string Account_Holder_LastName { get; set; }
public string Date { get; set; }
}
这是方法实现。
public string AccountDetails(string Account_Number)
{
var accountNumber = int.Parse(Account_Number);//It could be better to use TryParse
using (HalifaxDatabaseEntities context = new HalifaxDatabaseEntities())
{
var inOut = context.Current_Account_Deposit.Where(x => x.Account_Number == accountNumber).Select(w => new AccountTransaction
{
Account_Number = w.Account_Number,
Account_Balance = (decimal?)0M,
Deposit = (decimal?)w.Amount,
Withdrawal = (decimal?)null,
Date = w.Date,
Account_Type=null,
Account_Holder_Tittle = null,
Account_Holder_FirstName =null,
Account_Holder_LastName = null
}).Union(context.Current_Account_Withdraw.Where(x => x.Account_Number == accountNumber).Select(d => new AccountTransaction
{
Account_Number = d.Account_Number,
Account_Balance = (decimal?)0M,
Deposit = (decimal?)null,
Withdrawal = (decimal?)d.Amount,
Date = d.Date,
Account_Type = null,
Account_Holder_Tittle = null,
Account_Holder_FirstName = null,
Account_Holder_LastName = null
})).OrderBy(r => r.Date)
.Union(context.Current_Account_Details.Where(x => x.Account_Number == accountNumber).Select(e => new AccountTransaction
{
Account_Number = e.Account_Number,
Account_Balance = (decimal?)e.Account_Balance,
Deposit = (decimal?)0M,
Withdrawal = (decimal?)0M,
Date = e.Account_Creation_Date,
Account_Type=e.Account_Type,
Account_Holder_Tittle = null,
Account_Holder_FirstName =null,
Account_Holder_LastName = null
}))
.Union(context.Current_Account_Holder_Details.Where(x=>x.Account_Number ==accountNumber).Select(d=> new AccountTransaction
{
Account_Number = d.Account_Number,
Account_Balance = null,
Deposit =null,
Withdrawal = null,
Date = null,
Account_Type = null,
Account_Holder_Tittle =d.Tittle,
Account_Holder_FirstName=d.Account_Holder_First_Name,
Account_Holder_LastName=d.Account_Holder_Last_Name
}));
var js = new System.Web.Script.Serialization.JavaScriptSerializer();
return js.Serialize(inOut);
}
}
这是 Angular JS 代码。

这是我运行应用程序时的屏幕截图。 帐户类型标签未捕获数据
这是网络选项卡屏幕截图
最佳答案
我看不到您要显示的位置 帐号标签 ?
您只显示这些列
<th> Account Number</th>
<th> Money In</th>
<th>Date</th>
<th> Money Out</th>
<th>Date</th>
关于javascript - Angular Js web应用程序数据绑定(bind)无法从Sql数据库中捕获数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47965624/
