I have 3 function in my component . all 3 something are like this
Open Connection
Issue SQL statements(inse rt /update/delete)
Close connection
Now I have an application that uses these 3 functions in various parts.
I want this application to manage transaction.
When doing operation1 this is what I need
Start Transaction
Call Function1
Call Function2
Call Function3
Commit transaction
When doing operation2 this is what I need
Start Transaction
Call Function1
Call Function3
Commit transaction
So in short I want to manage transactions across connection to the same
DB.
Is this possible with ADO.Net or Data Access Application Blocks? Or
Should I go for System.Transact ion(have not read that yet).
Thanks

You cannot make transactions with more than one connection. You can do
the following.
Open ConnectionA
Start Transaction
Call Function1 (using ConnectionA)
Call Function2 (using ConnectionA)
Call Function3 (using ConnectionA)
Commit transaction
Close Connection
You can try to create 3 transactions (with 3 conections) and commit
then only if the 3 Functions success. Example:
Open ConnectionA
Open ConnectionB
Open ConnectionC
Start TransactionA
Start TransactionB
Start TransactionC
Call Function1 (using ConnectionA)
Call Function2 (using ConnectionB)
Call Function3 (using ConnectionC)
Commit transactions A, B, C if success, else rollback.
Close Connections A, B, C
Will try these out.
THanks for your help

Oh no! It's me and transactions again :)
I'm not really sure whether this is a limitation of psycopg or
postgresql. When I use multiple cursors in a transaction, the records
inserted at the start of the transaction aren't visible to those later
on in that transaction (using a different cursor).
Attached is a simplified example (the except's are a bit blunt, I know)
of what I'm trying to do. In reality, the different cursors are...

Hi
I have a transaction requirement that spawns across components. Typical
example is saving address, order etc. Each of these components will do
their part of transaction. If any of the transactions failed, then all
the transactions have to be rolled back. One way is to go for COM+
transaction using ServicedComponent. But this affects performance and
moreover we have no across database transactions. Another way I found is
to use...

Hello ppl,
Imagine some online system, based on PgSql. There are 'many' parts which
depends on each other. I will give small example, but instead of simple
table imagine changing tenths various tables (editing). So, 'change table A'
can be work for hours.
There are tables tableA and tableB. Changes are made by thin client. If
you change tableA, you have to also change tableB to 'finish' operation.
Between starting changing tableA...

I've implemented transactions in my dotNet 2.0 project using
System.Transactions and TransactionScope.

TransactionOptions options = new TransactionOptions();
options.IsolationLevel = System.Transactions.IsolationLevel.Serializable;
options.Timeout = new TimeSpan(0, 5, 0);
