Query returns 0 results [message #1816021]

Good morning,

A simple query, select * from matrix.db.JPOSupport returns zero results. When entering the query the autofill finds the correct class, matrix.db.JPOSupport.

I can easily find the class object via Dominator, REGEX search. I'm just wondering why the query returns zero results. I used both MAT 1.8 and 1.9.

Thanks,
Rich

select * from matrix.db.JPOSupport

finds all the instances of that class. Does the class have any instances?

select * from objects matrix.db.JPOSupport

would find the actual class object.
See https://help.eclipse.org/2019-09/topic/org.eclipse.mat.ui.help/reference/oqlsyntaxfrom.html for more information about OQL.
