Hello,

I am using Firebird 1.5.2 for my project and I encountered one
problem. When executing a (rather complex) query I get the following
error messages:

Implementation limit exceeded
Block size exceeds implementation restriction

Besides Firebird I am using Hibernate for the OR mapping. I have
searched the web for the description and found only the following page
http://www.ibphoenix.com/main.nfs?a=ibphoenix&page=ibp_fb1_faq
describing the problem (at the bottom of the page). However, I am not
sure where exactly the problem is and what does "..expressions do not
exceed the maximum size of a column..." mean.

Thanks a lot in advance

Tom
