事务内的T-SQL EXEC命令

Question

我需要使用通用EXEC命令从另一个执行存储过程。我需要确保所有sql语句都将处于事务状态。

BEGIN TRANSACTION
BEGIN TRY   

    SET @Esercizio = (SELECT ESERCIZIO_OBIETTIVI_CONSUNTIVARE from TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE)
    SET @TipoProcesso = (SELECT ISNULL(TipoProcesso, 'middle') from TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE)

    DELETE FROM TB_SCHEDE WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE
    DELETE FROM TB_SCHEDE_AUTOVAL WHERE MATRICOLA = @iMATRICOLA and COD_VALUTAZIONE = @iCOD_VALUTAZIONE
    DELETE FROM TB_OBIETTIVI WHERE MATRICOLA = @iMATRICOLA and ESERCIZIO =  @Esercizio
    DELETE FROM TB_OBIETTIVI_AUTOVAL WHERE MATRICOLA = @iMATRICOLA and ESERCIZIO =  @Esercizio

    EXEC AnotherStore @iCOD_VALUTAZIONE, @iMATRICOLA, @TipoProcesso
    COMMIT TRANSACTION

END TRY
BEGIN CATCH
    ROLLBACK TRANSACTION
END CATCH

如果该AnotherStore过程引发异常，那么数据库引擎是否确保从调用者存储过程回滚？

希望清楚。

有关存在事务时执行处理的示例，请参阅异常处理和嵌套事务：

create procedure [usp_my_procedure_name]
as
begin
    set nocount on;
    declare @trancount int;
    set @trancount = @@trancount;
    begin try
        if @trancount = 0
            begin transaction
        else
            save transaction usp_my_procedure_name;

        -- Do the actual work here

lbexit:
        if @trancount = 0   
            commit;
    end try
    begin catch
        declare @error int, @message varchar(4000), @xstate int;
        select @error = ERROR_NUMBER(), @message = ERROR_MESSAGE(), @xstate = XACT_STATE();
        if @xstate = -1
            rollback;
        if @xstate = 1 and @trancount = 0
            rollback
        if @xstate = 1 and @trancount > 0
            rollback transaction usp_my_procedure_name;

        raiserror ('usp_my_procedure_name: %d: %s', 16, 1, @error, @message) ;
    end catch   
end
