Global-dump-to-SQL

Globals in Caché / Ensemble / IRIS are normally invisible over SQL access
This example shows how to overcome this limit.
Globals are presented as content of a table with their subscripts and
the stored content.
The global to view is passed to SQL by a static WHERE condition that
requires 3 parameters:

• the global name (required)
• the start subscript (optional)
• the stop subscript (optional)

Just providing the global name results in a full global dump.
Globals may also be provided with the extended reference
and as this is a table all kind of additional conditions apply.

Be careful.
Correct quoting between SQL and Caché / Ensemble / IRIS could be a challenge

Example:
select * from zrcc_G.dump where zrcc_G.Dump(’^|“CACHE”|Sample.PersonD’,2,4)=1

ID	       Global	        Subscript	      Value
