read dat from a java class

Hello,

I have seen something like:

"values (package.Class)"

it was something about lucene integration?

how should be that class? where I can find documentation for this method
 to generate values for "VALUES"?


best regards,
Slavic

Hi Slavic,

VTIs were removed from Cloudscape before it was open-sourced as Derby. 
This is because the VTI syntax conflicts with the syntax for the 
corresponding ANSI SQL feature (function tables). DERBY-716 is an 
enhancement request to re-enable VTIs using the ANSI syntax. Currently, 
no one is working on this issue.

Regards,
-Rick

I have found with google

Virtual Table Interface (VTI)
A Cloudscape construct that provides an interface to external data
within an SQL-J statement. Classes that fulfill the VTI requirements can
be used in the FROM clause to provide data to a SELECT statement.
Cloudscape’s bulk import utility, COM.cloudscape.vti.FileImport, is an
example of such a class.


it's what I want? where is this in docs?

best regards,
Slavic
