使用多个 LINQ 语句的 SQL 日期时间溢出答案

【问题标题】：SQL DateTime Overflow Using Multiple LINQ Statements使用多个 LINQ 语句的 SQL 日期时间溢出
【发布时间】：2017-01-23 16:55:59
【问题描述】：

我有以下问题。

在下面的代码块中，第一次通过 if 语句触发，一切正常。第二次通过 formData.Where 出现 SQL DateTime 溢出错误。被拉回的值是一个字符串，与日期无关。被引用的记录确实有日期，但它是当天。我已经更改了这些 if 语句触发的顺序，无论哪个是第一个或第二个都没有关系。第二个总是抛出异常。

foreach (string riderGroup in riderGroups)
            {
                if (riderGroup == "69")
                {
                    var deathRiderValue = formData.Where(x => x.FieldName == "rider69Value").Select(x => x.FieldValue).Single().ToString();
                    var rider = _riderDataService.GetRiderById(Convert.ToInt32(deathRiderValue));
                    premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy });                        
                }
                if (riderGroup == "211")
                {
                    var gmabRiderValue = formData.Where(x => x.FieldName == "rider211Value").Select(x => x.FieldValue).Single().ToString();
                    var rider = _riderDataService.GetRiderById(Convert.ToInt32(gmabRiderValue));
                    premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy });
                }
                if (riderGroup == "96")
                {
                    var giveawayPromoValue = formData.Where(x => x.FieldName == "rider96Value").Select(x => x.FieldValue).Single().ToString();
                    if (giveawayPromoValue == "1")
                    {
                        var rider = _riderDataService.GetRiderById(5);
                        premiumAccount.AddRider(new PolicyRider { Rider = rider, PremiumAccount = premiumAccount, Policy = policy });
                    }
                }
            }

有什么想法吗？

FormData 类

public class FormData : Entity
{
    public virtual int FormSubmissionID { get; set; }
    public virtual string FieldName { get; set; }
    public virtual string FieldValue { get; set; }

    public FormData()
    {

    }
}

它继承的实体类

[Serializable]
public class Entity
{
    public virtual int ID { get; set; }
    public virtual bool IsActive { get; set; }
    public virtual DateTime DateCreated { get; set; }
    public virtual DateTime? DateModified { get; set; }
    public virtual int? ModifiedBy { get; set; }

    public Entity()
    {
        IsActive = true;
        DateCreated = DateTime.Now;
    }
    public override bool Equals(object obj)
    {
        if (ID != 0)
        {
            Entity obj2 = obj as Entity;
            return ((obj2 != null) && (ID == obj2.ID));
        }
        return base.Equals(obj);
    }

    public override int GetHashCode()
    {
        return (ID != 0) ? ID.GetHashCode() : base.GetHashCode();
    }

    public virtual void Deactivate()
    {
        IsActive = false;
    }

    public virtual void EncryptFields()
    {
    }

    public virtual object AddHistoryRecord()
    {
        return null;
    }
}

表单数据映射

public class FormDataMap : BaseMap<FormData>
{
    public FormDataMap ()
    {
        Table("tblFormData");
        Id(x => x.ID, "FormDataID");
        Map(x => x.FormSubmissionID);
        Map(x => x.FieldName);
        Map(x => x.FieldValue);
    }        
}

实体图

public BaseMap()
    {
        Id(x => x.ID);
        MapEntity();
        Map(x => x.IsActive).Not.Nullable().Default("1");
        Map(x => x.DateCreated).Not.Nullable().Default("getdate()");
        Map(x => x.DateModified);
        Map(x => x.ModifiedBy);
    }
    protected virtual void MapEntity()
    {
    }

【问题讨论】：

DateTime overflow 是什么意思？在所有这些代码中，DateTime 是在哪里使用的？实际错误是什么？ datetime 字段根本不允许您存储无效值，那么怎么会有溢出呢？您是否将日期存储为字符串并尝试将它们转换为DateTime？这本身就是一个严重的错误。
发布 full 异常，包括其调用堆栈。您可以通过Exception.ToString() 获得它。还要发布实际引发错误的代码。您在此处发布的内容似乎没有在任何地方使用日期
添加了异常和堆栈跟踪
您可能正在将0001-01-01 值传递给datetime 字段，但是，Single 调用如何导致 INSERT 语句？属性里面发生了什么？？？您的课程中是否有任何 getter 尝试在某处插入数据？

标签： c# sql-server linq

【解决方案1】：

您的异常定义了“fromdate”变量中发生的情况，它设置为空。在那里使用断点，“fromdate”内的跟踪值，它不能小于 1/1/1753 12:00:00 AM 并且不大于 12/31/9999 11:59:59 PM。如果您尝试将 DateTime 类型的变量设置为 null，则会发生此错误。将变量声明为可为空，即 DateTime? 。这样就可以解决问题了。

【讨论】：

有 2 列必须使用 DateTime。 1 是我们不允许为空的 DateCreated 和已经可以为空的 DateModified。
fromdate 是 DateTime 类型吗？
没有起始日期。我不确定你在哪里看到的。有一个 FormData 类继承自具有 DateCreated 和 DateModified 的 Entity 类。
分享那个类的实现。
添加了类和地图

【解决方案2】：

这应该是评论，但是太长了：

就像@M Adeel Khalid 在他的回答中所说，导致此异常的最常见条件是试图在 SQL Server datetime 列中放入一个有效的值strong> 用于 C#，而 invalid 用于 SQL Server。 这可能发生在哪里是关键，但很难从您提供的内容中判断。

您粘贴的代码的哪一行发生了异常？
堆栈跟踪中的那两个行号（粘贴在下面）呢？

c:\Users\hprentiss\Documents\SI Project\T3 Core\Dev\FrontOffice\HelperExtensions\FormProcessHelper.cs:314 中的 FrontOffice.HelperExtensions.FormProcessHelper.AddOnPremiumProcess(Int32 id)

C:\Users\hprentiss\Documents\SI Project\T3 Core\Dev\FrontOffice\Areas\NewBusiness\Controllers\ImportFormsController.cs:135 中的 FrontOffice.Areas.NewBusiness.Controllers.ImportFormsController.ProcessFormAddOnPremium(Int32 id)

我猜这些不是您自己的代码，但您可以从中获得线索。如果我们假设 Datetime.Now 是一个有效值，那么将 null 值更改为其他值怎么样，只是为了进行健全性检查？

【讨论】：

那里没有日期时间。它是 NHibernate 触发更新并决定空日期应该是最小值。
很公平，但这实际上是“带有日期时间的东西”。仅仅因为它发生在 NHibernate 中并不会改变异常的性质。
