The problem i have right now is,
I have updated the database table passwords with SHA1 encryption algorithm. Since its a hash algorithm which cannot be re-converted back to string, i need to get the original table with string format password content back.
I tried with rollback option, but its not getting back. I think this is because rollback works fine only when the application is alive. Once we close the application, the database engine does the auto-commit.
Please help me to resolve my problem. I need some guidelines to start with.
