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 SQL table all kinds 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('^|"SAMPLES"|Sample.PersonD',2,4)=1
ID Global Subscript Value
