我们有一个DACPAC（sqlproj）解决方案，它有一些表和一个运行一些DML查询的部署后脚本。 如果DML查询失败（我引发严重性为20的错误），我想回滚所有更改 - 包括dacpac完成的DDL更改和部署后文件更改。当我升级现有目标数据库时，这尤其有用。
我在发布DACPAC时努力进行原子数据库升级 - 只有在部署后脚本中的所有内容都成功时，才应发布DACPAC解决方案中提到的所有DDL更改。
由于DACPAC DDL更改在调用部署后脚本之前已提交，因此我认为使用DacServices.GenerateDeployScript将所有DAC更改作为单个脚本文件生成将有所帮助。看起来不那么直接。
有没有人尝试过这样的事情（失败/通过）？
我面临许多挑战，比如...... 创建/更改数据库不应该在事务中。 回滚没有发生。
[编辑10Nov]：粘贴dacpac生成的部署脚本，以便我能更好地解释我的问题（希望如此）

从我理解的问题中你知道如何为主脚本包含回滚，所以为了能够回滚前/后脚本你需要做类似的事情（只做快速测试，所以它可能不是理想的解决方案）。发布脚本2次，第二次因为表已经存在而失败：
前脚本：
IF (SELECT OBJECT_ID('tempdb..#tmpErrors2')) IS NOT NULL DROP TABLE #tmpErrors
GO
CREATE TABLE #tmpErrors2 (Error int)
GO
SET XACT_ABORT ON
GO
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
GO
BEGIN TRANSACTION
GO
--Your prescript part goes here
GO
IF @@ERROR <> 0
AND @@TRANCOUNT > 0
BEGIN
ROLLBACK;
END
IF @@TRANCOUNT = 0
BEGIN
INSERT INTO #tmpErrors2 (Error)
VALUES (1);
BEGIN TRANSACTION;
END
发布脚本：
CREATE TABLE tttt4 (a int);
GO
IF @@ERROR <> 0
AND @@TRANCOUNT > 0
BEGIN
ROLLBACK;
END
IF @@TRANCOUNT = 0
BEGIN
INSERT INTO #tmpErrors2 (Error)
VALUES (1);
BEGIN TRANSACTION;
END
GO
IF EXISTS (SELECT * FROM #tmpErrors2) ROLLBACK TRANSACTION
GO
IF @@TRANCOUNT>0 BEGIN
PRINT N'Post/Pre script finished'
COMMIT TRANSACTION
END
ELSE PRINT N'Pre/Post scripts failed'
GO
DROP TABLE #tmpErrors2
GO
