Is there any external documentation/example showing how to programmatically access a JDBC connection via DTP and create/populate tables via DTP. I am trying to develop a plugins which requires JDBC connection to persistent some of the data in database.
Thanks.
Joshua

Ok... First, the DDL question... The only example I can find is this:
private void executeDDL(String[] sqlStatements,
IConnectionProfile connectionProfile) {
DatabaseIdentifier databaseIdentifier = new DatabaseIdentifier(
connectionProfile.getName(), "");
if (databaseIdentifier != null) {
try {
Job job = new GroupSQLResultRunnable(null, sqlStatements, null,
null, databaseIdentifier, false, new HashMap(),
Messages.BaseExecuteAction_group_exec_title,
"Generate DDL");
job.setName(Messages.BaseExecuteAction_job_title);
job.setUser(true);
job.schedule();
PlatformUI.getWorkbench().getActiveWorkbenchWindow()
.getActivePage().showView(EditorConstants.RESULTS_VIEW);
} catch (Exception e) {
}
}
}
For the ability to pop up the property page as we do, check out
ConnectAction in o.e.d.connectivity.ui in the
o.e.d.connectivity.ui.actions package. The public void run(IAction
action) method pops up the dialog.

Hi Fitz,
Instead of directly using java.sql to establish a JDBC connection and manipulate the tables in the database, I would like to leverage DTP to use existing connection profile that is configured in the project and issue SQL statement. It is like the latter answer in your question.
Thanks.

I'll work up an example over the next couple of days. Sorry for the delay.

Ok...
So to get a named connection profile and connect via APIs, you use:
IConnectionProfile profile =
ProfileManager.getInstance().getProfileByName("myprofile");
IStatus status = profile.connect();
if (status.equals(IStatus.OK)) {
// success
} else {
// failure :(
if (status.getException() != null) {
status.getException().printStackTrace();
}
}
And then once you have your IConnectionProfile reference, you can get
the JDBC connection this way:
public java.sql.Connection getJavaConnectionForProfile
(IConnectionProfile profile) {
IConnection connection =
ProfileConnectionManager.
getProfileConnectionManagerInstance().getConnection(profile,
"java.sql.Connection");
if (connection != null) {
return (java.sql.Connection) connection.getRawConnection();
}
return null;
}
From there you can treat it like any other JDBC connection and create a
JDBC statement and execute it how you'd like.
Does that help?

There really isn't, or wasn't until I created one this morning for FAQs.
You can see it here: http://wiki.eclipse.org/DTP_FAQ
What exactly are you looking for? I have a number of things I'll add to
that page over time.

Hi Fitz,
Apart from using the raw JDBC connection, I am also looking for ways to programmatically invoke a ddl script from DTP. Is there a way to do it?
BTW, I tried your suggestion. It works except for
public java.sql.Connection getJavaConnectionForProfile( IConnectionProfile profile)
I have to change the following to get hold of the sql connection.
IManagedConnection connection = profile.getManagedConnection("java.sql.Connection");
if (connection != null) {
return (java.sql.Connection) connection.getConnection().getRawConnection();
}
return null;
Thanks.

Hi Joshua...
Thanks for the correction - I'll update that code in the FAQ too. :)
Let me ask around and see if we have an example of how to use the APIs
to invoke some DDL.

Hey Joshua...
Are you trying to execute DDL so that the results appear in the results
view or simply execute some DDL with the JDBC connection you got from a
connection profile?
