Rick Hillegas commented on DERBY-3971:
--------------------------------------

Hi Mayuresh,

The preferred (and supported) way to invoke the diagnostic VTIs is via the 
table function syntax, as described in the Reference Guide section titled 
"SYSCS_DIAG diagnostic tables and functions". So, for instance, the supported 
way to invoke  SpaceTable is this:

   select * from table( syscs_diag.space_table( 'APP', 'T' ) ) s

The information in the javadoc is stale and reflects the old Cloudscape syntax 
for instantiating a VTI. That syntax was largely deprecated as part of an 
effort to bring us into compliance with the ANSI/ISO standard. I don't see 
aliases defined for any of the diagnostic VTIs and I think that the javadoc 
should be corrected. Thanks for finding this.

> select * from new SPACETABLE ('<tablename>') t; throws an error

>            Priority: Minor

> The alias for SpaceTable diagnostic table does not work. I can reproduce this 
> on 10.2 trunk and also on the head.
> ij> select * from new SPACETABLE('t') ts;
> ERROR 42X01: Syntax error: SPACETABLE.
> The following works query works though,
> ij> select * from new 
> org.apache.derby.diag.SpaceTable('schemaname','tablename') a;
> The SpaceTable.java has a javadoc comment, as below,
>     Alternatively, the table can be invoked through the system alias 
> SpaceTable
>     <PRE> select * from new SPACETABLE('MYTABLE') t; </PRE>
> I believe either the alias should work or the javadoc comment should be 
> corrected.
