Question

I have enabled second level and query caches in my app
Looks like when I invoke following code

String sql = "update SOME_TABLE set SOME_FIELD=somevalue";
SQLQuery query = getSession().createSQLQuery(sql);
query.executeUpdate();

hibernate updates UpdateTimestampsCache for ALL tables. Why he does this? I have about 1000 tables and many sql queries in my app. I dont need this updates because I dont update cached tables via sql. It causes huge netwrok traffic and slowneess of application.

Is there a way to tell hibernate to NOT do any updates when running sql queries?

I found solution!

You can use addSynchronizedEntityClass() method

String sql = "update SOME_TABLE set SOME_FIELD=somevalue";
SQLQuery query = getSession().createSQLQuery(sql);
query.addSynchronizedEntityClass(SomeTable.class)
query.executeUpdate();

In this case it will reset just cache for SOME_TABLE
