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.... a full scan. Does it run fast if the ORDER BY is removed? ObjectDB Support ObjectDB - Fast Object ... 10 results - 460384 milliseconds. If ORDER BY is removed, the queries run very fast ...

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: ... so that when the parent is deleted all children are removed as well. Unfortunately, in one specific case that foreign key ...

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... SELECT e FROM Exercise AS e WHERE UPPER(e.name) = ?0 and then I am converting the parameter (representing by position ?0) to upper case.  I am certain the parameter value is correct, and there should be a matching record in the database, but my query returns no result. #1 2016-03-23 14:38 I am having trouble getting a simple string comparison to work in an SQL "where" clause.  It is my understan ...
