ODBC - MySQL Commit Error

Hi,

I am using euphoria odbc.e v1.33 with MySQL Database v5.0.6 + MySQL ODBC driver
v3.51 on WinXP (SP2).
Created MySQL entry under User DSN.

MySQL by default has autocommit set to true. (autocommit=1)
With autocommit set to 1, my program properly reads and updates the table.

I am trying to use commit and rollback by setting autocommit to false (set
session autocommit=0;)
While executing 
rc = commit(Pswrd_hndl)
I am getting the error "No Data".

I am executing the following steps:

1] connect to database using odbc - odbc-handle
2] execute "set session autocommit=0;" using prepareSQL() and executeSQL()
3] Prepare "begin;" using prepareSQL() - begin-handle
4] Prepare "update USERS set paswrd = ..;" using prepareSQL() - pswrd-handle
. 
. 
5] accept the new password
. 
. 
6] execute "begin;" using executeSQL(begin-handle)
7] Set parameters for password update using bindParameter(pswrd-handle,..) 
8] execute "update users set paswrd = ..;" using executeSQL(pswrd-handle)
9] if rc >= 0 commit the transaction  using commit(pswrd-handle)

At step 9, I am encountering this error "No Data".

The parameter for commit is "atom handle", I assumed it will be the statement
handle used for executing update statement.
I removed the "begin;" part and executed the code but ended up with same result.

Please advice. 

Regards,
Rad.
