I am new to Hibernate. I have a doubt.
I have a HashMap with a (Key,Value ) pair like this
Key Value
1 A
2 B
3 C

And i have a table like this

Table :
------------------------
Id Value
1 null
2 null
3 null
1 null
2 null
3 null

I want to write an update query to update the table with the values of the HashMap. Can anyone suggest how should my update query look like using java code.

At the End my table should look like this
Id Value
1 A
2 B
3 C
1 A
2 B
3 C


Please anyone help me ? :-)

First your HashMap should be stored on a persistent class (eg, a class mapped to Hibernate). Then you just save one instance of that class, containing your desired HashMap.

Like:

Container example = new Container();

example.setMap(new HashMap());
example.getMap().add(key, value);

session.save(example);

Thanks for the help elvanor. It was very useful. Can i solve the same problem using HQL(Hibernate Query Language) . Can you help in writing the HQL query. Can you help in that ?

I am not sure you can use an HQL query to update this (although I am not experienced in HQL). I think HQL is only for querying (I may be wrong).
