Question

我正在使用SQL Server2016。以下是适用于UPDATE和INSERT操作的代码。这意味着在将记录插入或更新到MyDB。[dbo]。[DocumentText]表中之后，相应的记录将插入到[AnotherDB]。[dbo]。[Audit]

但是同一场景不适用于同一表上的DELETE操作。但是，我确实从MyDB。[dbo]。[DocumentText]表中删除记录时触发了触发器。删除单个记录时，DELETE操作的结果如下：

（影响0行）（受影响的1行）

同时，UPDATE和INSERT操作的结果如下（考虑单个记录）：

（受影响的1行）（受影响的1行）

除此表外，此表上没有定义其他触发器...

CREATE TRIGGER [dbo].[TR_DocumentText_UPDATE_INSERT_DELETE]
   ON MyDB.[dbo].[DocumentText] AFTER INSERT, DELETE, UPDATE
   NOT FOR REPLICATION 
AS 
BEGIN
            ;WITH CTE AS (
            SELECT ISNULL(ins.DocumentID, del.DocumentID) AS DocumentID,
                CASE 
                    WHEN ins.DocumentID IS NOT NULL AND ins.DocumentID  = del.DocumentID THEN 'UPDATE' 
                    WHEN ins.DocumentID IS NOT NULL AND del.DocumentID IS NULL THEN 'INSERT'
                    ELSE 'DELETE' END AS AuditType         
                FROM inserted ins 
                FULL OUTER JOIN deleted del 
                        ON ins.DocumentID = del.DocumentID
                        )

            ,AUDIT_CTE AS (
            SELECT          
                CTE.DocumentID AS PkId, 
                'ODRT' AS Code,
                CTE.AuditType,
                'TSRE' AS MainEntityCode,
                doc.OppId AS MainEntityPkId
            FROM [MyDB].[dbo].[DocumentText] t WITH (NOLOCK)
            INNER JOIN [MyDB].[dbo].[Document] doc WITH (NOLOCK)
                        ON t.DocumentID = doc.DocumentID
            INNER JOIN CTE 
                        ON CTE.DocumentID = t.DocumentID
                            WHERE doc.OppId IS NOT NULL
                        )

            INSERT [AnotherDB].[dbo].[Audit] (Code, PKID, AuditType, MainEntityCode, MainEntityPKID)
            SELECT
                Code,
                PKID, 
                AuditType,
                MainEntityCode,
                MainEntityPkId
            FROM AUDIT_CTE;

END

Answer 1

按照建议的ZLK，我应该从[MyDB]。[dbo]。[DocumentText] t WITH（NOLOCK）中删除，然后直接查询为“ FROM CTE ...”。就是这样。

AFTER DELETE触发器触发，但不将记录插入审核表
