问题
I have a Intersystems CacheSQL Database which I have to work with in .net (VB or C#). The problem though, is that most data are not stored in Intersystem's CacheSQL, but rather in it's GLOBALS storage (which I think are arrays).
A GLOBALS array looks like this:
^BACKTR("INDX","COMPANY",1,63543,5870)
^BACKTR("DATA","STATISTICS",5870) = "613"_$c(1)_"3503||0"_$c(1)_"82"_$c(1)_"1"_$c(1)_"49"_$c(1)_"1"_$c(1)_"1950"_$c(1)_"63543"_$c(1)_"11301"_$c(1)_"3"_$c(1)_"CORP-A1"_$c(1)_"1656.06"_$c(1)_"150"_$c(1)_"0"_$c(1)_"N"_$c(1)_"82.8"_$c(1)_"198.72"_$c(1)_"12.42"_$c(1)_"N"_$c(1)_"0"_$c(1)_"0"_$c(1)_"0"_$c(1)_"N"_$c(1)_"Y"_$c(1)_"1"
Is there a way to call Database GLOBALS in Intersystems cacheSQL to VB.net or C#?
I am Using CACHE2010

You can get direct access to you globals with Caché eXTreme and Globals API but it is available since 2013.1
Or you could define custom Storage for your globals in you 2010 version, and get SQL access to your data and use it through ODBC or any other ways. You can find a lot examples here, how to do so.
UPD: You may try this class as an example for access to your data.
Class malky.test Extends %Persistent [ StorageStrategy = NewStorage1 ]
{
Property ID As %Integer;
Index ID On ID [ IdKey, Unique ];
Property prop1 As %String;
