Re: [dtp-connect-dev] Where to get the shared connection?
|
Hui,
Sorry for taking so long to get back to you.
Currently, the SQL model can be accessed using the java.sql.Connection
factory. This factory returns an object of type ConnectionInfo. From this
object, use the getSharedDatabase() method to get the SQL model Database
object. getSharedConnection() and getRawConnection() both return the
underlying java.sql.Connection used by the ConnectionInfo object.
We will be refactoring this for M3 so that it functions as specified in the
quick start guide (or at least close to what is specified). So, for M3,
you will need to use
org.eclipse.datatools.connectivity.sqm.internal.core.connection.ConnectionInfo
for the connection factory ID and getRawConnection() on the returned
object will be a ConnectionInfo object. The java.sql.Connection factory
will return a java.sql.Connection.
ConnectionInfo.getSharedConnection() is slightly misnamed, since it returns
the java.sql.Connection object used by the underlying ConnectionInfo
implementation; this is a carry over from the WTP code. This method, along
with other methods and object names may be adjusted when we complete our
API review prior to M4.
Also expected in the M3 release will be some form of connection management
that will facilitate connection sharing. I will have a preliminary design
out sometime next week.
Please let me know if you need anymore information.

A related question is how to get the catalog model. I have tried to create
a SQL model connection using
"org.eclipse.datatools.modelbase.sql.schema.Database" as the connection
factory id but got a NullPointerException. SQL Dev Tools is on a tight
schedule, so any help is highly appreciated!
Best Regards!

Hi,
Is there any API for SQL Dev Tools to get the shared connection
created by a connection profile? I see that ConnectionInfoImpl maintains a
shared connection, but the ConnectionInfoImpl instance itself can only be
accessed through IConnectionProfile.createConnection, which will cause
IllegalStateException when called more than once.
Best Regards!
