Gavin's comment from the mailing list:

Yes, I can certainly see the attraction - and it *has* been requested
before.

It would be nice to be able to plug in a something like:

NamingStrategy strategy = new MyCustomNamingStrategy();
Configuration cfg = new Configuration();
cfg.setNamingStrategy(strategy);

perhaps we could even allow this as:

<hibernate-mapping naming="pkg.MyCustomNamingStrategy">

The naming strategy itself would have methods like:

String getColumnName(String propertyName)
String getTableName(String className)
String overrideColumName(String columnName)
String overrideTableName(String tableName)


Add a feature request to JIRA!


Note that this is *really* easy to do, with just a little bit of playing
with the .cfg package.
Why not implement it yourself, and send a patch?

Description:
Initial feature idea from mailing list:

Hi all!

When I design database datamodels I usually encounter clashes between 
reserved names and names I'd like to use for my tables/columns, e.g. 
"user", "role", etc.. So I ended up prefixing all tables/views/columns: 
Tables have a "tbl" prefix, views a "qry" prefix and columns either 
have a "fld" or a prefix based on the datatype ("txt"/"str" for 
varchars, etc.).

I like to keep my mapping files small (/ to have few xdoclet tags) and 
like the fact that hibernate has smart default for column names: it 
uses the property's name. 

Would it be possible/would you consider it useful to be able to specify 
"default prefixes" for tables/columns so that I don't have to name my 
columns manually in my mappings when I have to use prefixes? Such 
settings could go into the SessionFactory configuration. 


Opinions?

Timo
