Why hibernate always call "update" statement after using "select" statement in MySQL?

Most probably, one of the properties of your entity does not return the exact same value that is set by hibernate after loading. Do you have some if statements like null handling or anything like this in a getter or setter?

Is there anybody help me in this case. I am using hibernate for select data from db, but when I check from sql debug log. I always see the update sql printed after I use "select" sql to get data from DB.

Edit: Code for getting the data:
@Override public MObjectId findResult(final MObjectId id, boolean isLocked) { Criteria c = getSession().createCriteria(Test.class); c.add(Expression.eq("objectId", id)); if(isLocked) { c.setLockMode("this", LockMode.UPGRADE); } Test extension = (Test) c.uniqueResult(); return (extension != null) ? new MObjectId("/ontPotsSipExtNr=" + extension.getId()) : null; }

user1525949 almost 11 yearsThe below is my code for getting data. Please help me check it. @Override public MObjectId findResult(final MObjectId id, boolean isLocked) { Criteria c = getSession().createCriteria(Test.class); c.add(Expression.eq("objectId", id)); if(isLocked){ c.setLockMode("this", LockMode.UPGRADE); } Test extension = (Test) c.uniqueResult(); return (extension != null) ? new MObjectId("/ontPotsSipExtNr=" + extension.getId()) : null; }

Stefan Steinegger almost 11 yearsI don't think that the problem is in the code to get the entity from the database. It is in the entity itself.
-
user1525949 almost 11 yearsI have already tried to remove LockMode.UPGRADE, but the issue was not still resolved. The update sql still appears in sql log.
-
user1525949 almost 11 yearsI just update my entity class. Could you please help me check?
-
Stefan Steinegger almost 11 yearsTo find the problem, turn on dynamic update using
@org.hibernate.annotations.Entity(dynamicUpdate = true)
. Check the update statement again. You see only the modified fields being updated. This helps finding the field that accidentally changed. -
user1525949 almost 11 yearsI try to turn on dynamicUpdate = true and see the log printed: 2013-08-14 16:24:38,163 DEBUG [RMI TCP Connection(9)-192.168.95.114]-[org.hibernate.SQL] update VoIPExtension set currentSipClientProfileType=?, currentSipSubscriberProfileType=? where id=?
-
Stefan Steinegger almost 11 yearsNow you know that in the class VoIPExtension the values currentSipClientProfileType and currentSipSubscriberProfileType changed. Check your code where these changes may happen.
-
user1525949 almost 11 yearsReally, I found out all the code and I didn't any code for updating the values of these above fields.
-
user1525949 over 10 yearsMany thanks Stefan. I know why the update statement is always called when selecting the data because its value is null. The type of attribute is configured as MObjectTypeUserType and Hibernate will base on the its equal method to decide the loaded object has change or not, but the equal method in my code is really wrong, it always return "false" if the object is null :(
-
Rudi Wijaya over 9 yearsFor Hibernate 4.3 / JPA 2.1, use
@org.hibernate.annotations.DynamicUpdate
instead of@Entity(dynamicUpdate=true)

Eric over 6 yearsA persistent entity has been associated with a database table row and it’s being managed by the current running Persistence Context. Any change made to such entity is going to be detected and propagated to the database (during the Session flush-time).
