Hi guys!
As you know there are two (at least) ways to get the stored value of the property of InterSystems IRIS class if you know the ID of an instance (or a record).
1. Get it by as a property of an instance with "Object access":
ClassMethod GetPropertyForID(stId As %Integer) As %String
{
set obj=..%OpenId(stId)
return obj.StringData
}
2. Get it as a value of a column of the record with "SQL access":
