Question

这是正常现象还是我缺少什么？这些语句不会产生回滚

BEGIN TRAN
BEGIN TRY
    CREATE TABLE dbo."aCTIONS" ("ID" int  NOT NULL IDENTITY(1,1) )

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Date" datetime

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Name" nvarchar(50) COLLATE Latin1_General_CI_AS

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "ActionID" int;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT PK_aCTIONS_ActionID 
            PRIMARY KEY NONCLUSTERED ("ActionID") 

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Notes" nvarchar(255) COLLATE Latin1_General_CI_AS;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_Notes DEFAULT (N'MISLIM') FOR "Notes"

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Consequence_Paid" bit;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_Consequence_Paid DEFAULT ((1)) FOR "Consequence_Paid"

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Reward_Paid" bit

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "username" int

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "time" time(0)

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "DateOnly" date;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_DateOnly DEFAULT (getdate()) FOR "DateOnly"
END TRY
BEGIN CATCH
    IF @@TRANCOUNT > 0
        ROLLBACK TRAN
END CATCH
IF @@TRANCOUNT > 0
    COMMIT TRAN

请注意，... ADD“ ActionID” int之后的大空间应该有NOT NULL，并且在该语句之后，下一条语句将尝试在其上创建PK约束。因此错误将在那里发生，这是可以的。但是不知何故，我在SSMS中显示了错误，之前回滚了，事务仍然处于活动状态，但是如何？为什么？

请注意，这只是我正在构建的脚本过程的输出，并试图确保如果存在错误将永远不会部分创建表。

谢谢，德扬

好的，好的，但是这只动物是由SSMS本身生成的：

/* Toprevent any potential data loss issues, you should review this script in detail before running it outside the context of the database designer.*/
BEGIN TRANSACTION
SET QUOTED_IDENTIFIER ON
SET ARITHABORT ON
SET NUMERIC_ROUNDABORT OFF
SET CONCAT_NULL_YIELDS_NULL ON
SET ANSI_NULLS ON
SET ANSI_PADDING ON
SET ANSI_WARNINGS ON
COMMIT
BEGIN TRANSACTION
GO
ALTER TABLE dbo.Stavke ADD
    dsad nchar(10) NULL
GO
ALTER TABLE dbo.Stavke SET (LOCK_ESCALATION = TABLE)
GO
COMMIT

？

除此之外，还需要做更多的事情，最后，我正在寻找一种解决方案，以将其全部放入交易中。

有一个解决方案：

https://dba.stackexchange.com/questions/29544/rollback-group-of-ddl-statements

以及更多信息：

https://docs.microsoft.com/en-us/sql/t-sql/language-elements/try-catch-transact-sql?view=sql-server-2017

这使我想到了这个解决方案：

SET XACT_ABORT ON; 

BEGIN TRAN
BEGIN TRY
    CREATE TABLE dbo."aCTIONS" ("ID" int  NOT NULL IDENTITY(1,1) )

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Date" datetime

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Name" nvarchar(50) COLLATE Latin1_General_CI_AS

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "ActionID" int;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT PK_aCTIONS_ActionID 
            PRIMARY KEY NONCLUSTERED ("ActionID") 

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Notes" nvarchar(255) COLLATE Latin1_General_CI_AS;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_Notes DEFAULT (N'MISLIM') FOR "Notes"

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Consequence_Paid" bit;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_Consequence_Paid DEFAULT ((1)) FOR "Consequence_Paid"

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "Reward_Paid" bit

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "username" int

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "time" time(0)

    ALTER TABLE "dbo"."aCTIONS" 
        ADD "DateOnly" date;

    ALTER TABLE "dbo"."aCTIONS" 
        ADD CONSTRAINT DF_aCTIONS_DateOnly DEFAULT (getdate()) FOR "DateOnly"
END TRY
BEGIN CATCH
    IF (XACT_STATE()) = -1  
    BEGIN
        ROLLBACK TRAN
        THROW
    END
END CATCH
IF (XACT_STATE()) = 1  
    COMMIT TRAN

，并且由于错误而未创建表。很酷，不是吗？
