Pi Web API Search Criteria Question

Hi Erik Lee​ ,

I don't think there's a way to do this in 1-Go. But I imagine doing a batch query with 2 steps could work. Please refer to: Batch Execute.

Batch {

1. Find the element with a template name and attribute(s) value search. You could probably use OR to search on 2 attributes.
2. Get all elements under the Element#1.

}

EDIT: I was using the wrong controller -'attributes' worked!

According to this link I just found, there is a way to do what I'm looking for: Knowledge (osisoft.com)

(see "7.Search for AF Attributes on an AF Database")

However, I cannot seem to get it to work. ("An exception has occurred. Please contact your PI Web API administrator for help in enabling debug mode."

)

I have an element name of 0020228481 and AF Attribute name of kW.

&query=Element:{Name:='0020228481'} Name:kW 

Hi Erik Lee​,

Your query looks ok to me. Perhaps there may be other issues.

Please try enabling DebugMode in PI Web API server following this article, PI Web API shows this: An exception has occurred. Please contact your PI Web API administrator for help in enabling debug mode.

And re-try your request to see why it failed.

Thanks Jinmo - I had the wrong controller in the url, so it's working now.

I'm glad to hear it's working now! Best,
