在我的组织中，我们正在做非常有限的日志记录或任​​何类型的记录，以捕捉谁在何时改变什么。

我在这里寻求帮助，以了解什么是捕获 SQL Server 数据库中发生的任何日志记录的最佳实践。

我正在考虑根据用户可以使用应用程序执行的重要业务用例来查看表格，然后制作一个包含以下字段的 xl 文件，以便我将此文件作为自己的参考。

当前 XL 文件开始捕获初始更改

我的问题：还有其他更好的方法来捕获数据库中的当前更改吗？SQL Server 中是否有一种方法可以用来确定我们是否正在捕获数据库中的任何日志记录？

我们没有任何 CDC 实施或 C2 审计跟踪启用或更改跟踪启用。

管理层希望利用数据库表中捕获的数据。

我正在做一个类似的项目，您可以使用下面的设计，我正在用学生主题示例进行解释

CREATE TABLE [dbo].[AudRel](
    [AudId] [int] IDENTITY(1,1) NOT NULL,
    [AudTableName] [varchar](100) NULL,
    [AudFieldName] [varchar](100) NULL,
    [AudFieldID] [varchar](30) NULL,
 CONSTRAINT [PK_AuditRel] PRIMARY KEY CLUSTERED 
(
    [AudId] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

CREATE TABLE [dbo].[Student](
    [StudentID] [int] IDENTITY(1,1) NOT NULL,
    [StudentName] [varchar](100) NULL,
 CONSTRAINT [PK_Student] PRIMARY KEY CLUSTERED 
(
    [StudentID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]


CREATE TABLE [dbo].[Student_Audit](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [StudentID] [int] NOT NULL,
    [StudentName] [varchar](100) NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[StudentSubject](
    [SSID] [int] IDENTITY(1,1) NOT NULL,
    [StudentID] [int] NULL,
    [SubjectID] [int] NULL,
 CONSTRAINT [PK_StudentSubject] PRIMARY KEY CLUSTERED 
(
    [SSID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

CREATE TABLE [dbo].[StudentSubject_Audit](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [SSID] [int] NOT NULL,
    [StudentID] [int] NULL,
    [SubjectID] [int] NULL
) ON [PRIMARY]

CREATE TABLE [dbo].[Subject](
    [SubjectID] [int] IDENTITY(1,1) NOT NULL,
    [SubjectName] [varchar](50) NULL,
 CONSTRAINT [PK_Subject] PRIMARY KEY CLUSTERED 
(
    [SubjectID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

CREATE TABLE [dbo].[Subject_Audit](
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [SubjectID] [int] NOT NULL,
    [SubjectName] [varchar](50) NULL
) ON [PRIMARY]


SET IDENTITY_INSERT [dbo].[AudRel] ON 
INSERT [dbo].[AudRel] ([AudId], [AudTableName], [AudFieldName], [AudFieldID]) VALUES (1, N'Student', N'StudentName', N'StudentID')
INSERT [dbo].[AudRel] ([AudId], [AudTableName], [AudFieldName], [AudFieldID]) VALUES (2, N'Subject', N'SubjectName', N'SubjectID')


SET IDENTITY_INSERT [dbo].[AudRel] OFF

SET IDENTITY_INSERT [dbo].[Student] ON 
INSERT [dbo].[Student] ([StudentID], [StudentName]) VALUES (1, N'Alex')
INSERT [dbo].[Student] ([StudentID], [StudentName]) VALUES (2, N'DSouza')
SET IDENTITY_INSERT [dbo].[Student] OFF

SET IDENTITY_INSERT [dbo].[StudentSubject] ON 
INSERT [dbo].[StudentSubject] ([SSID], [StudentID], [SubjectID]) VALUES (1, 1, 1)
INSERT [dbo].[StudentSubject] ([SSID], [StudentID], [SubjectID]) VALUES (2, 2, 1)
INSERT [dbo].[StudentSubject] ([SSID], [StudentID], [SubjectID]) VALUES (3, 2, 2)
SET IDENTITY_INSERT [dbo].[StudentSubject] OFF

SET IDENTITY_INSERT [dbo].[Subject] ON 
INSERT [dbo].[Subject] ([SubjectID], [SubjectName]) VALUES (1, N'English')
INSERT [dbo].[Subject] ([SubjectID], [SubjectName]) VALUES (2, N'Mathematics')
SET IDENTITY_INSERT [dbo].[Subject] OFF

然后使用以下查询动态获取已更改的字段。您需要从 UI 传递 AudRelID

DECLARE @TableName VARCHAR(100),@FieldName VARCHAR(100),@FieldID VARCHAR(100)

SELECT @TableName = [AudTableName]
, @FieldName=[AudFieldName]
, @FieldID=[AudFieldID] 
FROM [dbo].[AudRel] WHERE [AudId] = 1 -- (Ex : StudentHistory)


DECLARE @SQL NVARCHAR(MAX) = N'
 SELECT ID,'  + @FieldID +
','  + @FieldName + ' FROM ' +  @TableName + '_Audit ' + ' WHERE ' + @FieldID + ' = ' 
+ Convert(varchar(20),@FieldID) 

print @SQL
EXECUTE sp_executesql @SQL
