ADO.NET and working with different db
I need to implement reading data from one db and insert/update data in two other databases (Db2 and Db3). All databases are SQL Server.
Now I'm using the next scenario:
Open connection and start transaction for my source db.
1.1 Open connection and start transaction for Db2
1.2 Insert/Update records.
1.3 Commit/Rollback transaction
2.1 Open connection and start transaction for Db3
2.2 Insert/Up开发者_运维技巧date records.
2.3 Commit/Rollback transaction
Mark record as exported in source db.
Commit transaction.
Everything is working correct. But if I have exception in 1.2 or 2.2 steps, the current transaction will be rolled back, but transaction from other step will stay committed.
How I can implement scenario when if steps (1.2 or 2.2) have exception, steps 1.3 and 2.3 will be rolled back, too?
I can't use one transaction for Db2 and Db3 because I have exception
The transaction is either not associated with the current connection or has been completed.
Any ideas?
Thanks,
UPDATE: I solved my problem: Now I'm using the next scenario:
Open connection and start transaction for my source db.
1.1 Open connection and start transaction for Db1
1.2 Open connection and start transaction for Db2
1.3 Insert/Update in DB1
1.4 Insert/Update in DB2
1.5 Commit/Rollback transaction for Db1
1.6 Commit/Rollback transaction for Db2
Mark record as exported in source db.
Commit transaction.
You can use the TransactionScope class to interact with multiple databases inside a single distributed transaction.
using (TransactionScope scope = new TransactionScope())
{
//put all logic here
scope.Complete();
}
Here's another example
