我正在尝试创建一个数据库触发器，该触发器能够创建“事务”表的快照并将其与与插入、更新或删除任何数据行的日期有关的信息一起存储在“审计”表中。

提前道歉，但我对这种东西非常陌生！

就目前而言，我的触发器如下：

create trigger AuditTransactions
on dbo.Transactions
after insert, update, delete
as

    if exists(select * from inserted)
    begin
        if exists(select * from deleted)
        begin
            -- this is for an update
            update Audit
            set DeleteDate = getdate()
            where TransactionId in (select TransactionId from deleted)
        end 

        -- this is just for an insert
        insert into Audit
        select *, getdate() as CreateDate
        from inserted
    end
    else
    begin
        -- this is just for a delete
        update Audit
        set DeleteDate = getdate()
        where TransactionId in (select TransactionId from deleted)
    end

go

我的审计表如下所示：

    [TransactionId] [int] NOT NULL,
    [InvoiceNumber] [nvarchar](1) NULL,
    [InvoiceType] [nvarchar](1) NULL,

    [OrganizationId1] [int] NULL,
    [CreateDate] [datetime] NOT NULL,
    [DeleteDate] [datetime] NULL
) ON [PRIMARY]

GO

尝试执行触发器查询时，我收到以下错误消息：

Msg 213, Level 16, State 1, Procedure AuditTransactions, Line 17
Column name or number of supplied values does not match table definition.

这似乎是“插入审计”命令，但我不知道从这里做什么！

任何帮助将不胜感激，在此先感谢！

INSERT似乎记录得很差。对于VALUES()元素，它声明以下内容：

如果 Value 列表中的值与表中的列的顺序不同，或者表中的每一列都没有值，则column_list必须用于显式指定存储每个传入值的列。

（重点补充）

但是，我的理解和信念是，无论值/行的来源是什么，都适用相同的约束 - 除非您完全匹配表中的所有列，否则您需要提供column_list.

现在，对于您的实例，如果您只为表中的每一列提供一个值，可能会更容易：

insert into Audit
select *, getdate() as CreateDate,null as DeleteDate
from inserted

现在，我的另一个观察结果是，所有这些与条件控制流有关的事情都是毫无意义的——0insert行将没有任何效果，而对空表update使用in同样没有效果。所以我只有：

create trigger AuditTransactions
on dbo.Transactions
after insert, update, delete
as

    update Audit
    set DeleteDate = getdate()
    where TransactionId in (select TransactionId from deleted)

    insert into Audit
    select *, getdate() as CreateDate,null as DeleteDate
    from inserted

 insert into Audit
        select *, getdate() as CreateDate, null
        from inserted

您的“审计”表的列数比您插入的多（删除日期）；您需要命名所有列，或插入空值。

从风格上讲，为列命名更好——它可以清楚地说明什么在哪里，并在添加新列时避免错误。
