Hibernate execute multiple update statements within the same query

Question

I have two update statements. I want to have these two update statements in one query.

String hq1 = "update Table1 set xxxxx";
String hq2 = "update Table2 set xxxxxxxx";
Query query = session.createQuery(hq1);
int result = query.executeUpdate();

Suggest me the right approach. Thanks

The standard SQL syntax doesn't work in this way.
The expected syntax for an UPDATE is :

UPDATE table_name

SET column1 = value1, column2 = value2, ...

WHERE condition;

The column value have to be set with one specific value.
In your case, you want to SET the featured column with a value ( 0 or 1 ) that depends on the matching of the WHERE clause.
You cannot do it.

To achieve your requirement, you could use specific features of your DBMS (some provide a way to go further).
But to do it, you will also have to use native query and not Hibernate query.
