updating boolean value in spring data jpa using @Query, with hibernate

Question

I have spring-data and hibernate configured and running. I can save records using spring-data but for some reason I am not able to run query that will update all Boolean fields in a table.

I tried this:

@Query("update Content v set v.published = false where v.division = :division and v.section = :section")
void unPublishContent(@Param("division") String division, 
                         @Param("section") String section);

I also tried this:

 @Query("update Content v set v.published = 0 where v.division = :division and v.section = :section")
void unPublishContent(@Param("division") String division, 
                         @Param("section") String section);

Parameters division and section are coming true but no change on the table.

p.s. I am also using mysql database.

I'm using Spring 3.1 and Spring JPA Data. I was having a similar problem. I was constantly getting an error while trying to update multiple records in 1 query.

So, I had something like this.

@Query("UPDATE User u SET u.state = ?1 WHERE u.server.id = ?2")
public void updateAllUsers(long state, long serverid);

Error:

org.hibernate.hql.QueryExecutionRequestException: Not supported for DML operations

So, after googling for a while, I found out that you had to add @Modifying.

@Modifying  
@Query("UPDATE User u SET u.state = ?1 WHERE u.server.id = ?2")
public void updateAllUsers(long state, long serverid);

But then I was getting the following error:

...    
nested exception is org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; 
nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query
...

So, I figured my problem was now a transaction problem and I went back to google to research it and found out that you have to add @Transactional now. It appears that @Modifying also requires @Transactional.

@Modifying  
@Transactional
@Query("UPDATE User u SET u.state = ?1 WHERE u.server.id = ?2")
public void updateAllUsers(long state, long serverid);

but then I got the following error:

No value for key [org.apache.commons.dbcp.BasicDataSource (...) ] bound to thread

Again I googled for a while and came to the conclusion that my configuration was wrong and it turned out to be true. I was missing some xml configs.

<beans:bean class="org.springframework.orm.jpa.JpaTransactionManager" id="transactionManager">
    <beans:property name="entityManagerFactory" ref="entityManagerFactory"/>
</beans:bean>

<tx:annotation-driven transaction-manager="transactionManager"/>

It was long journey but I finally got it working. I hope this will help someone, trying to "pay it forward" as many others have helped me with their wonderful blogs, answers and comments.
