Question

I have a table (Oracle database) that looks like:

CREATE TABLE example
(
    idEx INTEGER,
    idAdh INTEGER,
    date DATE,
    PRIMARY KEY (idEx, idAdh)
)

I have generated the corresponding classes in Netbeans and I have two classes created for this table: Example.java and ExampleId.java, this last one containing the two values of my primary key.

Now let’s say I have some records here and I would like to delete one using only one value of the primary key (idEx for example, which is unique too). So first I need to get that row, but I can’t find a way to do this. Would it be possible to do something like this?

Example ex = (Example) session.get(Example.class, new ExampleId(?, idEx));

I’d need something to replace that ? that would act as a wildcard.

Or maybe this is absolutely not the way to go and in this case I’d really appreciate some advices.

Answer 1

You should be able to get the ex with a HQL query.
