How to parameterize the database schema

[Laxapanj]

I want my set of BIRT reports to target 2 different Oracle databases (e.g. test and prod), according to a report parameter. This can be done with the data source property bindings, by adding if - then logic in the various fields of the JDBC connection.

Now the problem is that these 2 databases have different schema names (but with same tables in them of course). What are my options to handle this?
- in the Data Set SQL request, I can put the schema before each table name <schema>.<table> but this cannot be parameterized AFAIK
- in the Data Source connection, I have seen that some databases provided a property in the JDBC URL connection to set the default schema. But I can't find any for Oracle.

I am using Birt RCP designer 2.3.0 and Oracle ojdbc14 driver.
Anyone had a similar problem ?
