Re: [hibernate-dev] HQL and spatial

Karel, Any further thoughts? I looked over the link you gave in regards to literals, but did not fully understand. I'd prefer this follow some "escape syntax" form, beyond that maybe you could just enumerate the literal types you'd want to support and their formats. ALso, I have not seen any

Re: [hibernate-dev] HQL and spatial

What do you mean "have these functions integrated into HQL"? What you describe is exactly how sql functions are supported as well. Perhaps you mean defining standard support for spatial functions. As a corollary, take something like the ANSI SQL TRIM function. Not all databases support TRIM as

Re: [hibernate-dev] HQL and spatial

Hi Steve, Have a look at this table: http://www.hibernatespatial.org/documentation/03-dialects/01-overview/ It provides an overview of the HQL functions that are supported in Hibernate Spatial. They are currently registered into each concrete SpatialDialect. I think it might be a good start

[hibernate-dev] HQL and spatial

Karel, etal We have discussed spatial-specific extensions to HQL for quite some time. But those discussions have always been kind of esoteric (boy wouldn't it be nice to have some spatial support in HQL). As we are working on redesigning the parsing and interpretation of HQL queries and since
