BLToolKit保存null而不是0

Question

（不能将其用作标记，但我们将BLToolkit用作ORM）

我有这个奇怪的问题，BLToolkit在我们的数据库中保存NULL而不是0。

如果您查看图像，这是我保存的值。 （gIdx代表GroupIndex）

以下是数据库中的结果。如果你查看GroupIndex列，我只有1和2.（这也适用于SortIndex列）

这是我的存储过程。该列只是一个NULL，INT

USE [ASTUSADMINISTRATION]
GO
/****** Object:  StoredProcedure [dbo].[stpr_GridColumnLayout_Update]    Script Date: 2015-06-22 08:08:28 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[stpr_GridColumnLayout_Update]
    @ID AS [usrID],  
    @Width AS int,
    @Index AS int,
    @IsCellMerged AS [usrBoolean],
    @GroupIndex AS int,
    @SortIndex AS int,
    @SortDirectionType AS int,
    @SummaryItemType AS int,
    @UpdatedDate AS datetime OUTPUT,
    @UpdatedUser AS [usrUsername]
AS
BEGIN
    SET NOCOUNT ON

    SET @UpdatedDate = GETDATE()

    -- Vérifier si c'est un groupe système
UPDATE [dbo].[GridColumnLayout] SET
    [Width] = @Width,
    [Index] = @Index,
    [IsCellMerged] = @IsCellMerged,
    [GroupIndex] = @GroupIndex, 
    [SortIndex] = @SortIndex,
    [SortDirectionType] = @SortDirectionType,
    [SummaryItemType] = @SummaryItemType,
    [UpdatedDate] = @UpdatedDate, 
    [UpdatedUser] = @UpdatedUser
  WHERE [GridColumnLayoutID] = @ID
END

您是否考虑过为相关字段设置默认约束值为0？
