SQL Server: guide with Nested Transactions Not Rolling Back as Expected
I need some guidance on I keep running into I'm working on a project and hit a roadblock. I'm relatively new to this, so bear with me. I'm relatively new to this, so bear with me. I'm working with a question with nested transactions in SQL Server 2019. I've implemented a series of stored procedures that insert records into multiple tables, and I'm using explicit transactions to handle errors gracefully. However, when an behavior occurs in one of the inner transactions, it seems that the outer transaction does not roll back as I expected. Here's a simplified version of the code I'm using: ```sql BEGIN TRY BEGIN TRANSACTION OuterTransaction; -- First insert INSERT INTO TableA (Column1) VALUES ('Value1'); BEGIN TRANSACTION InnerTransaction; -- This insert will unexpected result due to a constraint violation INSERT INTO TableB (Column2) VALUES (NULL); COMMIT TRANSACTION InnerTransaction; -- This will not be reached if the inner transaction fails INSERT INTO TableC (Column3) VALUES ('Value3'); COMMIT TRANSACTION OuterTransaction; END TRY BEGIN CATCH ROLLBACK TRANSACTION OuterTransaction; SELECT ERROR_MESSAGE() AS ErrorMessage; END CATCH; ``` When I run this, if the insert into `TableB` fails, I get an behavior message, but the `TableA` insert is still committed. The expected behavior is that if the inner transaction fails, the outer transaction should also rollback, but it seems to be only rolling back the inner transaction without affecting the outer one. I’ve also tried using `SAVEPOINT` to handle this, but the behavior remains the same. Could anyone explain why this is happening or how to properly manage nested transactions in SQL Server? I'm looking for best practices to ensure that all related operations are either fully committed or fully rolled back on any behavior, especially in complex stored procedures like these. This is part of a larger service I'm building. Thanks in advance! Any ideas what could be causing this? For context: I'm using Sql on Linux. Could someone point me to the right documentation? The project is a desktop app built with Sql.
