Return Auto Generated Key Query Mysql Java
Ms office 2010 product key generator. This example shows how to retrieve auto generated primary key by the database (via an insert statement). Following method of JdbcTemplate takes KeyHolder argument which will contain the generated key on the successful insert execution. Aug 23, 2013 The above code should give us auto generated primary key value. The one thing to note here is method prepareStatement. We passed two arguments first the insert query string and second an array of column name. The column name should be the primary key column name of table where you inserting the record. 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. ResultSet res = stmt.getGeneratedKeys; while (res.next) System.out.println('Generated key: ' + res.getInt(1)); Sample Java source code to retrieve auto increment key values in MYSQL using JDBC prepared statement. When we insert a record in a table that contains an auto increment column then we can easily obtain its id (primary key). Below example will show you how you can get the id of last inserted record in MySQL using Java (JDBC). In my example the table has following structure. In this case id column is auto increment primary key. Most of the time, the primary key is auto generated and once a row is inserted it is a common requirement to fetch auto generated primary key value after insert statement execution.So in this topic we will take a look into fetching that auto generated primary key once an insert statement is executed.We will implement this fetching of auto generated primary key while inserting through.

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???
You can use merge method of Session interface,
In the above code ,
nsb is the object to persist.
nsbC is the the object to return a copy of persisted object.

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,
Mysql Insert Query
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.
