autocommit

I have two branches A and B in a project that I am working on. B differs from A by a single commit, which is a section of the code completely independent from what I'm working on for the next while (aka, I will have many commits I want to push to both branch A and B). Is there any way in git that I can commit to both branch A and branch B at the same time, without having to commit it to one branch, checkout the other, and try to cherry pick out the commit(s). You could: make all your commits on A rebase B on top of A (if you haven't pushed B already, that is) That way, B will include all

In Hibernate API, there is a property hibernate.connection.autocommit which can be set to true. But in the API, they have mentioned that it is not recommended to set it like so: Enables autocommit for JDBC pooled connections (it is not recommended). Why is it not recommended ? What are the ill-effects of setting this property to true ? user3145373 ツ By default the autocommit value is false, therefore the transaction needs to be commited explicitly. This might be the reason why the changes not getting reflected in database, else can try flush to force the changes before commit. When you close

I have a web app that has been written with the assumption that autocommit is turned on on the database, so I don't want to make any changes there. However all the documentation I can find only seems to talk about using init_connect on the database, i.e. a global setting for all client connections. Is there a way to set autocommit=0 just when running mysql on a Linux command line (without having to type it in every time)? Perhaps the best way is to write a script that starts the mysql command line client and then automatically runs whatever sql you want before it hands over the control to you.

I have a Spring application which uses Hibernate on a PostgreSQL database. I'm trying to store files in a table of the database. It seems it stores the row with the file (I just use persist method on EntityManager), but when the object is loaded from the database I get the following exception: org.postgresql.util.PSQLException: Large Objects may not be used in auto-commit mode. To load the data I'm using a MultipartFile transient atribute and in its setter I'm setting the information I want to persist (byte[], fileName, size). The entity I'm persisting looks like this one (I've ommitted the

I did a big mistake that I updated a table without 'where' clause in MySQL :'( It is auto-committed. Is there any way to rollback from it? No, there's no query that will "undo" a committed data-modifying query. If you have a backup of the database, you can restore the backup and use DBA tools (in MySQL's case, it's mysqlbinlog ) to "replay" all data-modifying queries from the logs since the backup back to the database, but skip over the problem query. If you don't have a backup and all logs since the that backup, there's nothing you can do to recover the data. Look up transaction logs. I'll
