INSERT文は実行されますが、新しい行は作成されませんか？

Question

私は、UPDATEまたはINSERTで実行されるSQL Serverの社内テーブルのいずれかのトリガーを作成しました。 INSERTを扱うときは、2つの行を別々のテーブルに挿入する必要があります。最後のINSERT文を除いて、トリガのすべての部分が正しく動作しています。 SQLプロファイラでは、エラーは発生していませんが、INSERTが実行され、SQL Serverの独自のクエリにコピーして貼り付け、ローカル変数を定数に置き換えても問題なく動作します。しかし、トリガーは、それが挿入されるはずのテーブルに新しい行を作成していません。

私のコードは以下の通りです：私が間違って何をやっている

？どのようにしてINSERTが（SQLプロファイラによれば）エラーを出さずに実行されますが、まだ何もしていませんか？

Answer 1

いくつかの技術サポートの助けを借りて、私は実用的な解決策を見つけ出すことができました。

このトリガーを有効にしたステートメントのバッチには、INSERTステートメントによって加えられた変更が取り消されたUPDATEステートメントが含まれていたので、ステージングテーブルとスケジュールされたジョブを使用して、ステートメント。

私は新しいテーブルを作成：

USE [DLIDEMO3] 
GO 

CREATE TABLE [dbo].[DLI_STAGING_RAWS](
    [PROGRAM_ID] [nvarchar](30) NOT NULL, 
    [ID] [nvarchar](30) NOT NULL, 
    [DOCUMENT_ID] [nvarchar](128) NULL, 
    [DATE_VAL] [datetime] NULL, 
    [STRING_VAL] [nvarchar](128) NULL, 
    [CREATE_DATETIME] [datetime] NOT NULL 
) ON [PRIMARY] 

GO 

私は私のトリガーでINSERTステートメントを変更：

INSERT INTO [DLIDEMO3].[dbo].[DLI_STAGING_RAWS] 
     (PROGRAM_ID, ID, DOCUMENT_ID, DATE_VAL, STRING_VAL, CREATE_DATETIME) 
     VALUES 
      (N'VMPRTMNT', N'UDF-0000023', @part_id, GETDATE(), NULL, GETDATE()), 
      (N'VMPRTMNT', N'UDF-0000024', @part_id, NULL, N'NEW PART CREATED BY '+SYSTEM_USER, GETDATE()); 

そして、私は、これらのコマンドに続いて、1時間に1回実行するようにスケジュールされたジョブを作成しました：

WHILE EXISTS (SELECT * FROM [DLIDEMO3].[dbo].[DLI_STAGING_RAWS]) 
BEGIN 
    DECLARE 
    @program_id nvarchar(30), 
    @id nvarchar(30), 
    @document_id nvarchar(128), 
    @date_val datetime, 
    @string_val nvarchar(250), 
    @create_datetime datetime; 

    SELECT TOP 1 
    @program_id = PROGRAM_ID, 
    @id = ID, 
    @document_id = DOCUMENT_ID, 
    @date_val = DATE_VAL, 
    @string_val = STRING_VAL, 
    @create_datetime = CREATE_DATETIME 
    FROM [DLIDEMO3].[dbo].[DLI_STAGING_RAWS] 
    ORDER BY ID ASC; 

    IF DATEDIFF(mi, @create_datetime, GETDATE()) >= 15 
    BEGIN 

     INSERT INTO [DLIDEMO3].[dbo].[USER_DEF_FIELDS] 
     (PROGRAM_ID, ID, DOCUMENT_ID, DATE_VAL, STRING_VAL) 
     VALUES 
     (@program_id, @id, @document_id, @date_val, @string_val); 

     DELETE FROM [DLIDEMO3].[dbo].[DLI_STAGING_RAWS] 
     WHERE PROGRAM_ID = @program_id AND ID = @id AND DOCUMENT_ID = @document_id; 
    END; 
END; 

（条件DATEDIFF）

このソリューションは、私が前のINSERTのステートメントでやってみたことは本質的に何もしていませんが、それは1時間でずれています（これは時間単位ではありません）。特にこの場合の問題）。

すべての建設的な入力をありがとう。 :)
