I have SQL Server 2008 and want to do such a transaction:
begin transaction oo;
......
begin try
save transaction xx;
alter table ....; -- this will fail
alter table ....;
alter table ....;
end try
begin catch
rollback transaction xx; -- error here
end catch;
......
commit transaction oo;
At rollback transaction xx;
, I get the message
3931 The current transaction cannot be committed and cannot be rolled back to a savepoint. Roll back the entire transaction.
What am I doing wrong here?
Update To explain the scenario:
There is a big transaction "oo", which will change the table structures of the database from product version X to product version Y.
In the nested transactions, user-specific-tables should be tried to be changed (= inner transaction).
If an user-specific-table is somehow corrupted, the whole product-upgrade process should not be rolled back.
On the other hand, the user-specific-tables should not be upgraded if something else failed during the main product table upgrade (outer transaction).
