Problem in rolling back some transactions.

[Pooja Agarwal]

Hai All,

I am finding diff in rolling back some transactions.
Actually in my application (ie in Servlet) i have 5 callable statements to execute 5 stored procedures.
cstmt1,cstmt2,cstmt3,cstmt4,cstmt5
I have one connection object.

I have to execute these stored procedures in sequence. If any stored procedures returns non zero value i have to stop

execution and roll back all the transactions.
If all the 5 stored procedures return 0 then i have to commit the transaction.
i have used the following logic to do so.
But the problem is, i am failing to rollback the tranaction.
SP5 is returning non zero value, its displaying "error in SP5", but
is not rolling back all the transactions. Plz let me know how to roll back all the transactions.
Is there any mistake in my logic. ??

SP2 and SP3 are executed more than once and are included in for loop.

SP = Stored procedure.

            Execute SP1 
            if SP1 returns status == 0 then //1
               Execute SP2 (n number of times)
               if SP2 returns status == 0 then //2
                  Execute SP3 (n number of times)
                  if SP3 returns status == 0 then //3
                     Execute SP4
                     if SP4 returns status == 0 then //4
                        Execute SP5
                        if SP5 returns status == 0 then //5
                           Return Success.
                           Connection.Commit.
                           Display commited.
                        else //5
                        connection.rollback. 
                        Display error in SP5.
                     else  //4
                     connection.rollback. 
                     Display error in SP4
                  else  //3
                  connection.rollback. 
                  Display error in SP3
                else  //2
                connection.rollback. 
                Display error in SP2
              else  //1
              connection.rollback.
              Display error in SP1.
 

Any help would be appreciated.
Thanks in advance
POOJA.

Hi Pooja,

I just went through the history of queries posted by you.
From that, what I could understand, the possibility of the
error segment can be
1. either you need to make sure that you wanted to execute
all the callable statements using the same connection.
2. check your stored procedures, if there is any bug, like
commit within itself.

Otherwise, code, logic looks fine.
