JDBC and Hibernate mappings

Hi,

This is about use of JDBC along with Hibernate when required.

Mapping of objects is available to Hibernate. So it can know which column corresponds to which attribute of an object and generate SQL queries accordingly.

But if an application has to use JDBC (alongside with use of Hibernate) then to write a SQL query based on any attribute (a simple example), how would the application retrieve the corresponding column name?

It seems that the application has to ensure on its own that it uses correct column name (the one that is specified in the mapping). If I have not mistaken or missed anything, Hibernate does not seem to provide helper for application to retrieve such info.

Please let us know.

Thanks,
Jay

RTM chapter 13 of the reference manual.

If this is not enough, and you want to relay on the mapping look at

does this help?
http://www.hibernate.org/hib_docs/refer ... a-metadata

you can get all metadata info stored into the mapping files

Thanks Ernst and Anthony for a quick response. I feel information on your links will be sufficient for me.

I once wrote a nasty hack for something like this - don't know if it still works http://www.gloegl.de/26.html
