Sample Code Oracle stored procedure - In this simple implementation, call commit at the end of work done, and Rollback if any exception occur.

PROCEDURE SAVE_TWO_THINGS(
IN_THING_ONE IN VARCHAR2,
IN_THING_TWO IN VARCHAR2)
IS

BEGIN

INSERT INTO TABLEONE
(ACTIVE, THING_DESC)
VALUES
('Y', IN_THING_ONE);


INSERT INTO TABLETWO
(ACTIVE, THING_DESC)
VALUES
('N', IN_THING_TWO);

COMMIT;

EXCEPTION WHEN OTHERS THEN 
ROLLBACK;
END;

Today I need to implement transaction in .NET. Front end language was VB.NET and database was Oracle.

This transaction is being implemented using Oracle Data Access Provider - ODP.NET.

Simple implementation is that create and open a connection, begin transaction using that connection, create command using that connection, call stored procedures or statments using command(s), if every thing gone fine and success then call commit of that transaction else rollback, and in last close and dispose connection and transaction.

Be sure not to use commit, rollback or statement that causes transaction invalidate inside the procedure that is being called within .NET transaction, otherwise that .NET transaction scope will no longer valid as within that connection commit or rollback have been called.

Sample code that make my work done is :-

=============

Private Sub Save()
Dim conn As New OracleConnection("ConnString")
Dim trans As OracleTransaction
Dim success as Boolean = False

Try
conn.Open()
 trans = conn.BeginTransaction
success =  saveThingOne(conn)
If success Then
success = saveThingTwo(conn)
End If

If success  Then
 trans.Commit()
else
trans.Rollback()
End If

Catch ex As Exception
 trans.Rollback()
Finally
trans.Dispose()
conn.Close()
conn.Dispose()
End Try
End Sub

The great leader of Pakistan, Quaid-e-Azam, Muhammad Ali Jinnah - On this birth day...

I(Doc Kazi of flickr) got this rare photgraph from Mahmood on Victoria Road. He could not identify the others although the man in the center resembles the Nawab of Jungadh. The British General resembles Gen Musa. Mr Jinnah seems in a relaxed mood ostensibly with his favorite 'Craven A' cigarettes, which finally got him

In 1916, an even younger Mr Jinnah(in front center, mustachioed) presiding over a joint meeting of Indian National Congress and All India Muslim League.
