Thanks for the reply.
Also in jena 2, we can set TableNamePrefix on an IDBConnection with the
following statements:
IDBConnection conn = null;
IRDBDriver driver = conn.getDriver();
driver.setTableNamePrefix("prefix");
So what actually does this achieve. And how can we achieve the same
functionality in jena 3 with org.apache.jena.sdb.sql.SDBConnection class?

Hi,
You can check whether the dataset contains a specific named model with
dataset.containesNamedModel() [1]

Hi All,
We are upgrading from jena 2 to jena 3.
We have the following method in com.hp.hpl.jena.db.IDBConnection in jena 2:
------------------------------------------------------------------------------------------------------------
containsModel
boolean containsModel(String name) throws
RDFRDBException
Test if a given model is contained in the database.
Parameters:
name - the name of a model which may be in the database
Returns:
Boolean true if the model is contained in the database
Throws:
RDFDBException
RDFRDBException
Since:
Jena 2.0
------------------------------------------------------------------------------------------------------------
This method is used to check whether a given model exists in the underlying
database.
So is there a corresponding method to check for models in database in jena
3 in org.apache.jena.sdb.sql.SDBConnection.java class or in any other jena 3
jar?
