This will be especially convenient when static imports are introduced in Java 1.5. :)

Description:
generation of static final String for fields

While using Hibernate, we sometimes still call some 
direct sql queries that 
return resultsets that we process afterwards. We find 
easier to use direct sql 
than Hibernate in these cases. 


Anyway, Hibernate could provide some help: if every 
field in each persistent 
class had a corresponding constant string, that string 
could be used in the 
sql statement. 

Example: 

Given table A_table: varchar fieldone, int fieldtwo... 


Something like this woudl be generated: 

class Atable 

public static final String TABLENAME="A_table" 

public static final String FIELDONE ="fieldone" 

public static final String FIELDTWO ="fieldtwo" 

... 


And these constants can be used in the java code: 
String sql = "select ..." + A.FIELDONE +" = 'avalue'"... 



That way, when the field change in the db (as it 
happens very often, at least 
in our projects), and code is regenerated, it is easier 
to handle, as errors 
are catched at compile. We were doing that in our 
previous home made persistance 
stuff. Also, for the lazy, you get code completion to 
work :) 


The generation could be set conditionally in the xml or 
at command line when 
generating the code. It must be quite easy to add to 
the current generator, 
but maybe is not usefull for other people, I dont know.
