hi together,
I am evaluating JPA(OpenJPA) for one of our customers. The usage scenarios
have a very special
problem of which I do not know if there is a clear solution by using JPA:
The customers Oracle databases have very restricted access privileges:
==> the testing and development schemas/databases allow access to the
schema owner (i.e. user) e.g. "USRT"
==> the production schemas/databases only allow access to the schema
owner e.g. "USRP"
this means that during development all queries have to specify the usrt
owner, e.g.
select col1,col2,col3 from USRTEST.TBL_NAME where cond1=cond2 .
all of the statements have to be changed when being deployed to the
production system to:
select col1,col2,col3 from USRPROD.TBL_NAME where cond1=cond2 .
Currently I am implementing iBatis-based solutions where I configured a
global parameter ${owner} in a "datasource.properties"
file which is loaded in sql-map-config.xml at initialization time of the
iBatis SQLMaps Engine. In all queries throughout the project
I use the ${owner} variable -> so I just need to change the centralized
property value when deploying the system to the production
server.
Is there any similar approach which will solve this issue when working with
OpenJPA?
regards,
HANS
