Hi Michael Bayer, I can't set isolation_level='SERIALIZABLE' at global level, since it affect behaviour of other existing operations of my application.
So I done following changes where-ever I want to get changes committed by other transactions 1) Set Session isolation_level to READ-COMMITTED DBSession.execute("SET SESSION tx_isolation='READ-COMMITTED'"); 2) Query and get changes committed by other transactions 3) Set Session isolation_level back to REPEATABLE-READ DBSession.execute("SET SESSION tx_isolation='REPEATABLE-READ'"); * Unfortunately, It is not working as expected. Is there any other way to do it ?? Thanks, -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
