Question

我正在创建一个触发器，我想在编辑行时解析Deleted和Inserted的所有列。因此，如果删除的col1与插入的col1不同，则将此更改存储在另一个表中。以下是我如何实现这一目标，但我想让它变得充满活力。

    if not exists (select * from deleted d join inserted i on d.Cisitid = i.Cisitid ) and @Action in ('U') -- UpdateCisitid
BEGIN
    select  @audit_oldvalue = Cisitid from deleted;
    select @audit_value = Cisitid from inserted;

    insert into [dbo].[AuditTrailCTables]([TSid],[TableName],[TSField],[OldValue],[NewValue],[changedate],[Change_Action],[Change_user],[Columns_Updated])
    select Cisitid,@tablename,'Cisitid', @audit_oldvalue, @audit_value,getdate(),@Action, coalesce(ModifiedBy,suser_name()), 'Cisitid'
    from inserted 

    --Cformid

    select  @audit_oldvalue = Cformid from deleted;
    select @audit_value = Cformid from inserted;

    insert into [dbo].[AuditTrailCTables]([TSid],[TableName],[TSField],[OldValue],[NewValue],[changedate],[Change_Action],[Change_user],[Columns_Updated])
    select Cisitid,@tablename,'Cformid', @audit_oldvalue, @audit_value,getdate(),@Action, coalesce(ModifiedBy,suser_name()), 'Cformid'
    from inserted 

    --CreatedDate

    select  @audit_oldvalue = CreatedDate from deleted;
    select @audit_value = CreatedDate from inserted;

    insert into [dbo].[AuditTrailCTables]([TSid],[TableName],[TSField],[OldValue],[NewValue],[changedate],[Change_Action],[Change_user],[Columns_Updated])
    select Cisitid,@tablename,'CreatedDate', @audit_oldvalue, @audit_value,getdate(),@Action, coalesce(ModifiedBy,suser_name()), 'CreatedDate'
    from inserted 

    --CreatedBy

    select  @audit_oldvalue = CreatedBy from deleted;
    select @audit_value = CreatedBy from inserted;

    insert into [dbo].[AuditTrailCTables]([TSid],[TableName],[TSField],[OldValue],[NewValue],[changedate],[Change_Action],[Change_user],[Columns_Updated])
    select Cisitid,@tablename,'CreatedBy', @audit_oldvalue, @audit_value,getdate(),@Action, coalesce(ModifiedBy,suser_name()), 'CreatedBy'
    from inserted 
END

尝试使用UPDATE功能：

IF UPDATE(Cisitid)
    insert into [dbo].[AuditTrailCTables]([TSid],[TableName],[TSField],[OldValue],
    [NewValue],[changedate],[Change_Action],[Change_user],[Columns_Updated])
         select Cisitid,@tablename,'Cisitid', @audit_oldvalue, 
    @audit_value,getdate(),@Action, coalesce(ModifiedBy,suser_name()), 'Cisitid'
    from inserted 

etc..

已删除和已插入的每列的SQL
