Hi Ram�n,
I am interested in the way to get the TableName from the Class,
in my case the Table Name is the same as the Class Name (standard storage
method)
but I can not get the Class name also:
##this.Name does not work
in the manual I found:
Set result = ##class(%ResultSet).%New("%Dictionary.ClassDefinition:Summary")
Do result.Execute()
While (result.Next()) {
Write result.Data("Name"),!
}
and
Set cdef = ##class(%Dictionary.ClassDefinition).%OpenId("Sample.Person")
Write cdef.Name,!
=> ??? isnt "cdef" the same as "##this" ???
