Rick Hillegas updated DERBY-3069:
---------------------------------
Attachment: derby-3069-08-aa-stringArrayTable.diff
Attaching derby-3069-08-aa-stringArrayTable.diff. This patch adds a VTI which I
find useful for ad-hoc testing of VTIs. Committed at revision 1431623.
Here is the javadoc for the VTI:
/**
* <p>
* This is a table function which creates a StringArrayVTI out of
* a space separated list of column names, and a varargs of rows.
* Each row is a space separated list of column values. Here is
* a sample usage:
* </p>
*
* <pre>
* connect 'jdbc:derby:memory:db;create=true';
*
* create function leftTable
* (
* columnNames varchar( 32672 ),
* rowContents varchar( 32672 ) ...
* )
* returns table
* (
* a varchar( 5 ),
* b varchar( 5 )
* )
* language java parameter style derby_jdbc_result_set no sql
* external name
'org.apache.derbyTesting.functionTests.tests.lang.VarargsRoutines.stringArrayTable';
*
* select * from table( leftTable( 'A B', 'APP T', 'APP S' ) ) l;
* </pre>

> Varargs were added in Java 5. It would be nice if Derby let you invoke a
> function bound to a method with a variable length argument list. The
> Reference Guide states a small number of restrictions for methods which can
> be invoked as Derby functions: They must be public, static, and not have
> arguments which are long datatypes. I see no reason that Derby shouldn't be
> able to resolve and invoke functions which are bound to methods which don't
> suffer these limitations but which have variable argument lists.
