SQL Server 2008 には、新しい try/catch 構造があります。入れ子になった一連のストアド プロシージャでエラーが発生した場合は、呼び出し履歴をエラー テーブルに記録したいと考えています。問題は、トランザクションを開始した場合 (これはデータベースを更新する操作に当てはまります)、try/catch ステートメントのキャッチ部分のコードがトランザクションをロールバックすると、エラー テーブルに書き込まれたレコードが削除されることです。 .
これを回避する方法についてのヒントは大歓迎です。
いくつかのオプション:
SO SET XACT_ABORT ON に関する質問 (エラー処理あり)
これにより、トランザクションを含む 2 つのテスト テーブルと 3 つのネストされたプロシージャが作成されます。
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureA') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureA
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureB') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureB
if exists (select * from sysobjects where id = object_id(N'[dbo].ProcedureC') and OBJECTPROPERTY(id, N'IsProcedure') = 1) drop procedure [dbo].ProcedureC
if exists (select * from sysobjects where id = object_id(N'YourLogTable') and OBJECTPROPERTY(id, N'IsTable') = 1) drop table YourLogTable
if exists (select * from sysobjects where id = object_id(N'YourTestTable') and OBJECTPROPERTY(id, N'IsTable') = 1) drop table YourTestTable
