I'm using PI System Explorer (188.8.131.5258) and I'm having trouble trying to get a data lookup aggregate based on a list of components.
What I'm trying to achieve is something as simple as an attrbute defined as a table lookup:
select 'pippo' from dual
union all select 'pluto' from dual
union all select 'caio' from dual
and an attribute (@Attribute1) of type String that I'd like to store 2 values: pippo and pluto
The table lookup would then have a where clause on the first column value that has to be IN the list defined in @Attribute1.
I've tried to define @Attribute1 in numerous ways but the only time it works is when it's of type String and has only a single value from the table lookup (so, either pippo, pluto or caio).
Is there a way to achieve what I'm trying to achieve with PI System Explorer?
Thanks in advance.
