實體框架7無效的列名稱

c# entity-framework entity-framework-core

我正在為現有數據庫創建EF7映射,並且我收到“無效列名”錯誤。拋出錯誤的代碼是:

public class DepositContext : DbContext
{
    public DbSet<tblBatch> Batches { get; set; }
    public DbSet<tblTransaction> Transactions { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<tblBatch>().HasKey(b => b.BatchID);

        modelBuilder.Entity<tblTransaction>().HasKey(t => t.TransactionID);

        modelBuilder.Entity<tblBatch>().HasMany(b => b.tblTransactions).WithOne().HasForeignKey(t => t.fBatchID);
    }
}

public class tblBatch
{
    public int BatchID { get; set; }
    public int? fDepositID { get; set; }
    public Guid BRN { get; set; }
    public string BCN { get; set; }
    public decimal? BCT { get; set; }
    public string BatchFileName { get; set; }

    public List<tblTransaction> tblTransactions { get; set; }
}

public class tblTransaction
{
    public int TransactionID { get; set; }
    public string TRN { get; set; }
    public string TransactionStatus { get; set; }

    public int fBatchID { get; set; }
    public tblBatch tblBatch { get; set; }
}

這會拋出一個Invalid column name 'tblBatchBatchID1'.當我使用SQL事件探查器查看發送到數據庫的內容時,它是:

exec sp_executesql N'SELECT [t].[TransactionID], [t].[fBatchID], [t].[TRN], [t].[TransactionStatus], [t].[tblBatchBatchID1]
FROM [tblTransaction] AS [t]
INNER JOIN (
    SELECT DISTINCT TOP(1) [b].[BatchID]
    FROM [tblBatch] AS [b]
    WHERE [b].[BatchID] = @__BatchId_0
) AS [b] ON [t].[fBatchID] = [b].[BatchID]
ORDER BY [b].[BatchID]',N'@__BatchId_0 int',@__BatchId_0=37

有人知道如何解決這個問題嗎?

熱門答案

EF RC1中存在一些錯誤,這些錯誤在查詢生成中產生了錯誤的列名。查看可能與您的問題相關的錯誤列表

您可以通過顯式設置列名來嘗試解決此問題。

modelBuilder.Entity<tblBatch>().Property(e => e.BatchID).HasColumnName("BatchID");

如果您感覺很勇敢,可以嘗試升級到RC Core的RC2夜魘,看看問題是否已解決。
