以下は、すべてのテーブルにある監査トリガーです。私の問題は、何らかの理由でデータを失ったことであり、監査トリガーによってログに記録されたレコードからデータを取り戻すことだけを望んでいます

ALTER TRIGGER [Production].[trQuotationEntryAuditChanges] 
   ON  [Production].[QuotationEntry]
   AFTER DELETE,UPDATE
AS 
BEGIN
    SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED
    SET NOCOUNT ON;

        INSERT INTO [Security].[Audit]
            ( [OUID],[NUID],[TableName], [OldContent],[NewContent])

        SELECT 
            [OUID]=(SELECT TOP 1 [UID] FROM DELETED),   
            [NUID]=(SELECT TOP 1 [UID] FROM INSERTED),
            [TableName]=object_name([parent_obj]),
            [OldContent]=CAST((SELECT * FROM DELETED I FOR XML RAW) AS XML),
            [NewContent]=CAST((SELECT * FROM INSERTED I FOR XML RAW) AS XML)
        FROM sysobjects 
        WHERE
            [xtype] = 'tr' 
            and [name] = OBJECT_NAME(@@PROCID)
END

これは私のトリガーがデータをテーブルに記録する方法です [Security].[Audit].[OldContent];xml の下からデータを抽出してテーブルに書き込む方法はありますか?

これを試して：

SELECT A.*, t.t.value('@UID', 'int'), t.t.value('@ScanID', 'int') 
   /*, ...*/ FROM Security.Audit A CROSS APPLY 
OldContent.nodes('/row')t(t)
