- MySQL Connector/J 5.1 Developer Guide / JDBC Concepts / Retrieving AUTOINCREMENT Column Values through JDBC 6.4 Retrieving AUTOINCREMENT Column Values through JDBC Before version 3.0 of the JDBC API, there was no standard way of retrieving key values from databases that supported auto increment or identity columns.
After the query is executed, I use this code to return back the generated key for the record I just inserted
I need to be able to do the same thing with Hibernate but I don't know how. Can anyone please help???
Oct 11, 2006 Just recently I ran into a problem with what seems to be a deficiency in the Oracle Database. When trying to return an auto-generated key as is done in Microsoft's SQL database, it seems Oracle for whatever reason didn't add this capability, the key couldn't be passed back to the.Net call.

Wednesday, January 08, 2003 10:57 Subject: Re: retrieving auto-generated keys on bulk insert The code that we have has a low-level save. Meaning if a statement causes the creating of more than one key then the ResultSet object should return all. Using auto generated keys.; 2 minutes to read +2. A way to make IDENTITY values available to an application that is updating a database table without a requiring a query and a second round-trip to the server. Updates that have to use the auto-generated key feature must operate against a table that contains an IDENTITY column. This field is known as an auto increment field in MySQL, and either an identity or serial field in other databases like SQL Server or Postgresql. In either case, the problem is the same: How to get the value of the primary key field following your SQL INSERT statement.) Java Spring JDBC - Auto-generated database key source code.

Why do you need to do this? The save method will return the value of the generated identifier. Calling merge is an unecessary step.
This is the code that I'm trying to convert to Hibernate. I'm fairly new to Hibernate so please bear with me.
the dao.insertApplication() returns the generated key as a String (appKey) because it will be a foreign key in the next insert of this transaction (dao.insertAppModuleInfo), and the generated key (moduleKey) will also serve as a foreign key for dao.insertModuleFunctionality() and dao.ModuleBusArea(). Am I making myself clear? There's probably a better way to do this in hibernate, I just don't know how. I'm hoping you all can help.
Thanks,
if you are gerenating your AppId using key generators then it automatically hibernate does for you.
for e.g.
i have a POJO
I am not setting user_id becoz it is auto generated by database sequence or hibernate incerement
just after calling the session.save(user)
if i want user_id i just now user user.getUserId() it will return user id generated by hibernate while inserting.
