No, you need one table (or view if you like) containing all data. If you can't do this, you could write your own copy of a JDBCDataModel that can query multiple tables, or, that changes its SQL queries to use UNION statements. I imagine it will slow down a lot.
If you mean, can you use a table with preferences with a model that ignores preferences, sure you can. The extra column is ignored. 2010/7/19 Young <[email protected]>: > Hi, > I have three tables, one is with preference and another two are without > preference.
