Anirudh,

The SQL Query Builder (SQB) is a Data Tools Platform project component
integrated with BIRT. It requires the use of a DTP database connection
profile. It is technically feasible to convert a BIRT JDBC data source
design to a DTP database profile, so it can be used with SQB. Please go
ahead and submit an enhancement request in Bugzilla, if this feature is
important.
You can certainly adopt the DTP SQB component directly. Here are some links
to the SQB project:

>> why is it only a part of eclipse framework and not included in the RCP
>> Designer

The SQB component has dependency on other bundles (i.e. org.eclipse.ui.ide
and org.eclipse.debug.core) that are not normally packaged in a RCP
application.
