Question

我正在尝试使用存储过程创建数据库日志。但问题是它不跟踪多列更新或修改。

以下是我的存储过程

ALTER Procedure [dbo].[Proc_TrackFollowup]
     @Followup_ID int,@FollowType nvarchar(50),@ContactPerson nvarchar(50),
     @FollowDate datetime,@FollowTime nvarchar(50),@Status nvarchar(50),@Comment nvarchar(MAX)

     AS
     DECLARE @OldFollowup_ID int
     DECLARE @OldFollowType nvarchar(50)
     DECLARE @OldContactPerson nvarchar(50)
     DECLARE @OldFollowDate datetime
     DECLARE @OldFollowTime nvarchar(50)
     DECLARE @OldStatus nvarchar(50)
     DECLARE @OldComment nvarchar(MAX)
     DECLARE @OldCompanyName nvarchar(50)
     DECLARE @audit_action varchar(100)

     SELECT @OldFollowup_ID=Followup_ID,@OldCompanyName=CompanyName,@OldFollowType=FollowType,@OldContactPerson=ContactPerson,@FollowDate=FollowDate,@OldFollowTime=FollowTime,@OldStatus=Status,@OldComment=Comment
     from FollowUpTable where Followup_ID=@Followup_ID

     UPDATE FollowUpTable SET FollowType=@FollowType,ContactPerson=@ContactPerson,FollowDate=@FollowDate,FollowTime=@FollowTime,Status=@Status,Comment=@Comment where Followup_ID=@Followup_ID

     IF @OldFollowType<>@FollowType
     SET @audit_action='Follow Type Changed From ' + Cast(@OldFollowType AS VarChar) + ' to ' + Cast(@FollowType As Varchar)  

     IF @OldContactPerson<>@ContactPerson
     SET @audit_action='Contact Person Changed From ' + Cast(@OldContactPerson AS VarChar) + ' to ' + Cast(@ContactPerson As Varchar)

     IF @OldFollowDate<>@FollowDate
     SET @audit_action='Follow Date Changed From ' + Cast(@OldFollowDate AS VarChar) + ' to ' + Cast(@FollowDate As Varchar)

     IF @OldFollowTime<>@FollowTime
     SET @audit_action='Follow Time Changed From ' + Cast(@OldFollowTime AS VarChar) + ' to ' + Cast(@FollowTime As Varchar)

     IF @OldStatus<>@Status
     SET @audit_action='Status Changed From ' + Cast(@OldStatus AS VarChar) + ' to ' + Cast(@Status As Varchar)

     IF @OldComment<>@Comment
     SET @audit_action='Comment Changed From ' + Cast(@OldComment AS VarChar) + ' to ' + Cast(@Comment As Varchar)

     INSERT INTO LoggerFollowUpTable
     (Followup_ID,CompanyName,FollowType,ContactPerson,FollowDate,FollowTime,Status,Comment,Audit_Action,Audit_Timestamp) 
     VALUES(@Followup_ID,@OldCompanyName,@FollowType,@ContactPerson,@FollowDate,@FollowTime,@Status,@Comment,@Audit_Action,getdate());

我已经在c＃表单中给出了更新选项，其中Type是一个下拉列表，我将其传递给@ Type.But每当我从下拉列表中选择另一个项目并将其传递给存储过程时，它都不会跟踪修改。甚至之后在表单中编辑多个字段，我面临同样的问题

请建议更改存储过程

如果你从一个不同的角度接近它可能会更容易。有一个跟踪更改的表格。

CREATE TABLE [dbo].[LoggerFollowUpTable](
    [LogId] [int] IDENTITY(1,1) NOT NULL,
    [TableName] [varchar](50) NOT NULL,
    [FieldName] [varchar](50) NOT NULL,
    [RecordId] [int] NOT NULL,
    [OldValue] [varchar](50) NULL,
    [NewValue] [varchar](50) NULL,
    [DateChanged] [datetime] NOT NULL
) ON [PRIMARY]

GO

然后在你的存储过程中更像（重复每个字段）

IF @OldFollowType<>@FollowType
BEGIN
 INSERT INTO LoggerFollowUpTable (TableName, FieldName, RecordId, OldValue, DateChanged), NewValue) VALUES ('FollowUpTable', 'FollowType', @Followup_ID, Cast(@OldFollowType AS VarChar), Cast(@FollowType AS VarChar), GetDate())
END

然后，每个值都会更改一行。

如果你想在每次价值测试之后坚持你所需要的INSERT ......那就像......

 IF (@OldFollowDate<>@FollowDate)
 BEGIN
    SELECT @audit_action='Follow Date Changed From ' + Cast(@OldFollowDate AS VarChar) + ' to ' + Cast(@FollowDate As Varchar)
     INSERT INTO LoggerFollowUpTable
 (Followup_ID,CompanyName,FollowType,ContactPerson,FollowDate,FollowTime,Status,Comment,Audit_Action,Audit_Timestamp) 
 VALUES(@Followup_ID,@OldCompanyName,@FollowType,@ContactPerson,@FollowDate,@FollowTime,@Status,@Comment,@Audit_Action,getdate());  
END

您错过了开始和结束关键字，请尝试此操作，右键单击数据库并选择新查询打开新的SQL查询窗口，然后使用代码：

         ALTER Procedure Proc_TrackFollowup
         @Followup_ID int,
         @FollowType nvarchar(50),
         @ContactPerson nvarchar(50),
         @FollowDate datetime,
         @FollowTime nvarchar(50),
         @Status nvarchar(50),
         @Comment nvarchar(MAX),
         @OldFollowup_ID int,
         @OldFollowType nvarchar(50),
         @OldContactPerson nvarchar(50),
         @OldFollowDate datetime,
         @OldFollowTime nvarchar(50),
         @OldStatus nvarchar(50),
         @OldComment nvarchar(MAX),
         @OldCompanyName nvarchar(50),
         @audit_action varchar(100),

         AS
         Begin

         SELECT @OldFollowup_ID=Followup_ID,@OldCompanyName=CompanyName,@OldFollowType=FollowType,@OldContactPerson=ContactPerson,@FollowDate=FollowDate,@OldFollowTime=FollowTime,@OldStatus=Status,@OldComment=Comment
         from FollowUpTable where Followup_ID=@Followup_ID

         UPDATE FollowUpTable SET FollowType=@FollowType,ContactPerson=@ContactPerson,FollowDate=@FollowDate,FollowTime=@FollowTime,Status=@Status,Comment=@Comment where Followup_ID=@Followup_ID

         IF @OldFollowType<>@FollowType
         SET @audit_action='Follow Type Changed From ' + Cast(@OldFollowType AS VarChar) + ' to ' + Cast(@FollowType As Varchar)  

         IF @OldContactPerson<>@ContactPerson
         SET @audit_action='Contact Person Changed From ' + Cast(@OldContactPerson AS VarChar) + ' to ' + Cast(@ContactPerson As Varchar)

         IF @OldFollowDate<>@FollowDate
         SET @audit_action='Follow Date Changed From ' + Cast(@OldFollowDate AS VarChar) + ' to ' + Cast(@FollowDate As Varchar)

         IF @OldFollowTime<>@FollowTime
         SET @audit_action='Follow Time Changed From ' + Cast(@OldFollowTime AS VarChar) + ' to ' + Cast(@FollowTime As Varchar)

         IF @OldStatus<>@Status
         SET @audit_action='Status Changed From ' + Cast(@OldStatus AS VarChar) + ' to ' + Cast(@Status As Varchar)

         IF @OldComment<>@Comment
         SET @audit_action='Comment Changed From ' + Cast(@OldComment AS VarChar) + ' to ' + Cast(@Comment As Varchar)

         INSERT INTO LoggerFollowUpTable
         (Followup_ID,CompanyName,FollowType,ContactPerson,FollowDate,FollowTime,Status,Comment,Audit_Action,Audit_Timestamp) 
         VALUES(@Followup_ID,@OldCompanyName,@FollowType,@ContactPerson,@FollowDate,@FollowTime,@Status,@Comment,@Audit_Action,getdate()); 

         End

存储过程不跟踪列修改
