ibm_db doesn't support SAVEPOINT? #103

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Simple test script:

import ibm_db
ibm_db_conn = ibm_db.connect('pydev', 'db2inst1', 'secret')
import ibm_db_dbi
conn = ibm_db_dbi.Connection(ibm_db_conn)
cur = conn.cursor()
cur.execute('SAVEPOINT test ON ROLLBACK RETAIN CURSORS')
cur.execute('RELEASE SAVEPOINT test')

will cause exception:

ProgrammingError: ibm_db_dbi::ProgrammingError: Statement Execute Failed: 
[IBM][CLI Driver][DB2/LINUXX8664] SQL0880N  SAVEPOINT "TEST" does not exist or 
is invalid in this context.  SQLSTATE=3B001 SQLCODE=-880

The test works fine with pyodbc.

Found the problem...

>>> ibm_db.autocommit(ibm_db_conn)
1

>>> ibm_db.autocommit(conn)
0

Autocommit is actually still on. Reopen issue 6?

The error you are getting in SAVEPOINT is because of your application is in 
autocommit mode and in this mode there is no concept of SAVEPOIT.

Please turn autocommit OFF before using SAVEPOINT, you can set it by following 
command.

>>>ibm_db_dbi.set_autocommit(0)

I am agree with your view regarding autocommit default value. We will modify 
this in our next release.
