Slow searching with two indexes

I'm running queries on a large database (tens of millions of objects), and I'm running into a performance problem using two indexes.  An entity I'm querying has two indexed fields - one is the primary key (id) and so is different for each object, and the other is an object reference that only has a few tens of different values.   When I query by just the primary key, it's (of course) extremely fast, but when I also query using the other key, queries can take minutes. #1 2016-11-15 12:01 I'm running queries on a large database (tens of millions of objects), and I'm running into a performance ...

Foreign key constraint issue

Hi, I'm trying to create two tables (Parent and Child) with a foreign key constraint from Child to Parent so that when the parent is deleted all children are removed as well. Unfortunately, in one specific case that foreign key constraint doesn't apply and I can't figure out what I'm missing. The definitions of the classes are as follows: ... @OneToMany(cascade = {CascadeType.MERGE, CascadeType.REMOVE}, mappedBy = "parent", orphanRemoval = true)     ... the parent's list get deleted, whereas I'd want to remove all orphaned child entities (as with a foreign key constraint). ...


String comparison in query where clause

I am having trouble getting a simple string comparison to work in an SQL "where" clause.  It is my understanding that queries are case sensitive by default and I do not want that, so I am constructing the query as follows...
