Question

我有两个独立的存储过程，第二个在第一个存储过程的try块中调用。

第一个程序框架代码：

CREATE PROCEDURE [dbo].[Procedure1]
-- Parameters
@procedure1_parameter

AS
SET ANSI_NULLS ON
SET NOCOUNT ON
SET XACT_ABORT ON
BEGIN

  BEGIN TRANSACTION;
  BEGIN TRY

  EXEC [dbo].[Procedure2] @procedure2_parameter;

  END TRY

  BEGIN CATCH

  SELECT
    ERROR_SEVERITY() AS ErrorSeverity,
    ERROR_MESSAGE() AS ErrorMessage;

  IF @@TRANCOUNT > 0
    BEGIN
      ROLLBACK TRANSACTION;

    END

  END CATCH;

  IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;

END

第二个程序框架代码：

CREATE PROCEDURE [dbo].[Procedure2]
-- Parameters
@procedure2_parameter

AS
SET ANSI_NULLS ON
SET NOCOUNT ON
SET XACT_ABORT ON
BEGIN

  BEGIN TRANSACTION;
  BEGIN TRY

  -- Procedure2 code 

  END TRY

  BEGIN CATCH

  DECLARE @ErrorMessage NVARCHAR(4000);
  DECLARE @ErrorLine INT;
  DECLARE @ErrorNumber INT;
  DECLARE @ErrorProcedure NVARCHAR(200);
  DECLARE @ErrorSeverity INT;
  DECLARE @ErrorState INT;

  SELECT
    @ErrorNumber = ERROR_NUMBER(),
    @ErrorSeverity = ERROR_SEVERITY(),
    @ErrorState = ERROR_STATE(),
    @ErrorProcedure = ERROR_PROCEDURE(),
    @ErrorLine = ERROR_LINE(),
    @ErrorMessage = ERROR_MESSAGE();

  IF @@TRANCOUNT > 0
    BEGIN
      ROLLBACK TRANSACTION;

      RAISERROR (@ErrorMessage,
      @ErrorNumber,
      @ErrorSeverity,
      @ErrorState,
      @ErrorLine,
      @ErrorProcedure
      );
    END

  END CATCH;

  IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;

END

正如您所看到的，它们具有几乎相同的代码，除了第二个代码在catch块中引发了错误。如果第二个程序失败，第一个程序应该从第二个程序中捕获错当我们在第一个存储过程的try块中有第二个存储过程调用时，这是处理事务回滚/提交的正确方法吗？

在procedure1中调用procedure2时处理事务回滚
