Question

Folks,

I am using Play 1.2.5. The database is Oracle 10g and I am using an existing table for my application.

I am generating a unique key like this:

@GeneratedValue(strategy=GenerationType.SEQUENCE)
public int transactionId;

When I use the below code, the transactionId is generated and saved successfully ib the database:

transactionDetails.save();

But I am not able to get the uniquely generated transactionId once the save operation performs successfully. The save method returns a type <JPABase>. Then how can I retrieve the transactionId after a successful save operation from the <JPABase> ?

Note: I don’t want to make another DB hit for fetching the transactionId because I believe that there might be some way to retrieve it for a successful save operation.

Please let me know about this.

Thanks,

You should be able to write

TransactionDetails savedDetails = transactionDetails.save();

save() method actually is not returning JPABase, it is declared as so you will get the saved entity
