Question

我创建了一个视图，你可以看到：

CREATE VIEW [dbo].[ViewMTO]
AS
    SELECT        
        dbo.Lines.Unit, dbo.Lines.LineNumber, dbo.Lines.DocumentNumber, 
        dbo.BaseMaterials.Name AS MaterialName, 
        dbo.MaterialDescriptions.Name AS MaterialDescription, 
        dbo.MaterialDescriptions.Description, 
        dbo.MaterialScopes.ScopeName, dbo.MaterialScopeObjectNames.ObjectName, 
        dbo.MaterialDescriptions.Size1, dbo.MaterialDescriptions.Size2, 
        dbo.MaterialDescriptions.ItemCode, dbo.Materials.Quantity, 
        dbo.Materials.Discipline
    FROM            
        dbo.Materials 
    INNER JOIN
        dbo.Lines ON dbo.Materials.LineId = dbo.Lines.Id 
    INNER JOIN
        dbo.BaseMaterials ON dbo.Lines.BaseMaterialId = dbo.BaseMaterials.Id 
    INNER JOIN
        dbo.MaterialDescriptions ON dbo.Materials.MaterialDescriptionId = dbo.MaterialDescriptions.Id 
    INNER JOIN
        dbo.MaterialScopes ON dbo.MaterialDescriptions.MaterialScopeId = dbo.MaterialScopes.Id 
    INNER JOIN
        dbo.MaterialScopeObjectNames ON dbo.MaterialDescriptions.MaterialScopeObjectId = dbo.MaterialScopeObjectNames.Id

在我的应用程序中，我想调用它，因为你可以看到：

public List<DAViewMTO> ViewMTOByDetail()
{
    List<DAViewMTO> lst = new List<DAViewMTO>();
    lst = _ctx.Database.SqlQuery<DAViewMTO>("SELECT * FROM [SPMS2].[dbo].ViewMTO").ToList();
    return lst;
}

但是这个查询永远不会返回任何结果。我在这个函数中设置了一个断点，断点从不通过这一行：

 lst = _ctx.Database.SqlQuery<DAViewMTO>("SELECT * FROM [SPMS2].[dbo].ViewMTO").ToList();

我有另一个具有此结构的其他函数的视图，并且没有任何问题。当我直接在SQL中执行查询时，它没有任何问题。

我在UI中调用它：

private void frmViewMaterialTakeOf_Load(object sender, EventArgs e)
    {
        splashScreenManager1.ShowWaitForm();
        gridControl.DataSource = new BindingList<DAViewMTO>(_materialRepository.ViewMTOByDetail()) { AllowNew = true };
        splashScreenManager1.CloseWaitForm();

    }

Database.SqlQuery不会返回任何结果
