无效的ObjectName xxx.dbo.xxx，但它就在那里
我不明白，为什么下面的代码不起作用：
//Database connection
using (var db = new KassenautomatEntities())
{
//Create Model
var quittung = new WAWI_Quittungen
{
QuittungText = "WebInterface",
QuittungBetrag = amount,
QuittungDatum = DateTime.Now,
KartenIDKassierer = 0,
KartenIDKunde = userInfo.CardId,
Zahlungsart = 4,
ClientNr = WebInterfaceInfo.ClientId,
LastPrintDate = null,
PrintedCount = 0,
StornoQuittungID = null,
Status = 0
};
//Save Model
db.WAWI_Quittungen.Add(quittung);
db.SaveChanges(); //<----- Crash
我收到此错误：
无效的对象名称'KasseJournal.dbo.WAWI_Quittungen'
一般来说每张桌子都适合我。这是唯一一个没有的。
WAWI_Quittungen有一个名为QuittungID的自动增量的主键，我在这里没有定义，但我不认为，这就是问题所在。
我还从diagramm中删除了表格并将其从数据库中添加。
有兴趣点：
- 在SQL Studio中，它的名称为
[Kassenautomat].[dbo].[WAWI_Quittungen]，而不是KasseJournal.dbo.WAWI_Quittungen。 - 如果我通过实体框架从这张表中读取，我没有问题。
- 我在
KasseJournal的整个解决方案中完成了文本搜索，但结果为零。
我当然搜索过很多东西。我没有这个问题之一：
- 数据库触发器
- 连接错误的数据库
- 将新对象设置为false
我缺少什么？
的ConnectionString：
<add name="KassenautomatEntities" connectionString="metadata=res://*/Models.Database.KassenautomatModel.csdl|res://*/Models.Database.KassenautomatModel.ssdl|res://*/Models.Database.KassenautomatModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.;initial catalog=Kassenautomat;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
使用生成的SQL：
SELECT
[GroupBy1].[A1] AS [C1]
FROM ( SELECT
COUNT(1) AS [A1]
FROM [dbo].[WAWI_Quittungen] AS [Extent1]
WHERE [Extent1].[KartenIDKunde] = @p__linq__0
) AS [GroupBy1]
不工作SQL：
INSERT [dbo].[WAWI_Quittungen]([QuittungText], [QuittungBetrag], [...])
VALUES (@0, @1, @2, @3, @4, @5, @6, NULL, @7, NULL, @8)
SELECT [QuittungID]
FROM [dbo].[WAWI_Quittungen]
WHERE @@ROWCOUNT > 0 AND [QuittungID] = scope_identity()

1 个答案:
答案 0 :(得分：1)
好吧我明白了。我给你错误的信息，对不起。
这是一个触发器。
我正在研究数据库触发器而不是表触发器。我不知道MsSQL每个表都有一个Trigger Definition。在MySQL中，它是一个很大的触发器表。
所以我删除了触发器，一切正常。
