I asked the following question during the PI OLEDB webinar

 

Can you give an example of a simple SQL statement that gives the average of  values that match a given alias, say "pH", across all modules in a MDB?

 

The speaker mentioned the following concepts relevant to this question :

 

Versioning

 

Historization of modules

 

Can someone give guidance to find the right answer?

 

Thanks
